  3. 3. Announcement OverviewQuestion:What did IBM announce on July 12th, 2011 for the IBM zEnterprise™ System?Answer:On July 12th 2011, IBM announced significant enhancements and extensions to the IBM zEnterpriseSystem that was initially rolled out just one year before.The IBM zEnterprise System, introduced last July is arguably the most significant new systemsarchitecture in 20 years and took smarter computing and optimized systems to a whole new level.This revolutionary system introduced a new hybrid computing model capable of integrating andmanaging multiple (or today’s most prevalent) architectures in a single integrated system making itpossible to begin collapsing individual islands of computing to reduce complexity, improve security,and bring business applications and workloads closer to the data they need. This hybrid environmentallows clients to optimize workloads, deploy enterprise clouds, and take action based on real-timeanalytics and big data.Highlights of this latest announcement include:A new entry point for hybrid computingWe have rounded out the zEnterprise System family with the introduction of the newest entry-levelmainframe, the IBM zEnterprise 114 (z114). The z114 offers a lower hardware entry cost, extensivegrowth options and significant improvements in packaging, performance and total system scalabilityover its predecessor, the IBM System z10 Business Class™ (z10 BC™). It can be used as a standalonedevelopment machine, a coupling facility or as an on ramp for any growing business looking to exploitmainframe technologies. And, when combined with the IBM zEnterprise BladeCenter® Extension(zBX) and Unified Resource Manager, the z114 extends the mainframe’s unique hybrid capabilities toclients of all sizes.Extending the scope of the hybrid computing modelWe have extended the scope of the hybrid computing model and the zEnterprise BladeCenterExtension (zBX) with the ability to integrate select HX5 IBM System x® blades running Linux®, and inthe future Microsoft® Windows®1, to open up the benefits of the hybrid model to a whole new set ofworkloads. This continues to add to the options in zBX that were previously announced includingselect IBM blades such as POWER7® blades running AIX®, and specialized workload optimizers suchas DataPower® XI50z and the IBM Smart Analytics Optimizer.We also issued two important statements of direction with regard to the Unified Resource Manager.The first is in the management area of Operational Controls. An enhancement will be available relatedto the auto-discovery and configuration support for new resources. We can now auto detect theinstallation of storage resources installed in support of blades and make them available to the UserInterface when doing workload resource configurations. Without this, users have to manually enter allthe storage resources. The second Statement of Direction is around delivery of APIs, or applicationprogramming interfaces, to enable the integration, discovery, monitoring, and management of UnifiedResource Manager from external tools, (such as Tivoli® or CA); providing greater flexibility and choicefor companies to build this into their integrated service management model. These APIs will be openand documented so they are available for clients to use if they’d like. Access will be by using commonscripting languages like Perl and Python. 3
  4. 4. Enhancements to the zEnterprise server technology at its coreA number of additional enhancements for the zEnterprise have been made which strengthen existingcapabilities in areas such as I/O performance, clustering and security. These new enhancementsapply to both the existing IBM zEnterprise 196 (z196) as well as the new z114.In the area of connectivity, we have revamped the I/O subsystem to be PCIe-based (PeripheralComponent Inter-connect Express), supporting the industry standards and direction for highperformance I/O facilitating increased capacity, port granularity, infrastructure bandwidth, andreliability. The new PCIe I/O drawer provides an 8 GBps host bus for performance and increasedgranularity. zHPF and the new FICON-Express8S cards offers huge performance boost on zHPFenabled storage devices, and the new OSA-Express4S offers more granularity.In the area of security, we delivered multiple cryptography improvements through TKE (Trusted KeyEntry) and updates to various industry cryptographic standards and Crypto Express3 has beenenhanced to support key ANSI and ISO standards for the banking and finance industry.In the area of clustering, new Hub cards offer increased coupling performance for 12x InfiniBand® (forshort distance) providing a 40% improvement in latency and 1x Infiniband (for long distance) and moreconnectivity for 1x InfiniBand (long distance asynchronous card) with a 4 port card to facilitate thefurther consolidation of ISC3 links into the Infiniband technology. And finally are using STP as the timesource for the entire zEnterprise. So the processor itself now becomes the NTP server for the zBX.SummaryThe mainframe continues to evolve while holding true to our core strengths of the platform. ThezEnterprise is driving new relevance and expanding its role to support smarter computing. Theseongoing enhancements with the zEnterprise System demonstrate our steadfast commitment tocontinuously deliver innovation and value for our clients.1 All statements regarding IBM future direction and intent are subject to change or withdrawal withoutnotice, and represents goals and objectives onlyQuestion:What did IBM announce on April 12, 2011 for IBM System z®?Answer:In Hardware Announcement 110-177, "IBM zEnterprise BladeCenter Extension (zBX)" dated July 22,2010, IBM introduced a new dimension in computing with the announcement of the IBM zEnterpriseServer (zEnterprise). This first in the industry offering makes it possible to deploy an integratedhardware platform that brings mainframe and distributed technologies together - a system that canstart to replace individual islands of computing and can work to reduce complexity, lower costs,improve security, and bring applications closer to the data they need.As part of that announcement we provided a road map for IBMs hybrid capabilities, the delivery ofspecial-purpose workload optimizers and select general-purpose IBM blades. In 2010 we began todeliver, first with our business analytics solution - IBM Smart Analytics Optimizer and thengeneral-purpose POWER7 blades. In February 2011 we continued with the announcement of the IBMWebSphere® DataPower XI50 for zEnterprise (DataPower XI50z), a multifunctional appliance for theSystem z environment that can be implemented to help provide XML hardware acceleration, and tostreamline and secure valuable service-oriented architecture (SOA) applications.The next step of the road map is to incorporate select IBM System x technologies, originally targetedfor the first half of 2011. The reaction to delivering IBM System x capabilities has been very positive,with our clients also asking that we support Microsoft Windows. Therefore, today we are revising ourroad map to include planned support for Windows on System x as well as a revised schedule for IBMSystem x blade delivery on the IBM zEnterprise Systems. 4
  5. 5. In the third quarter of 2011, IBM intends to offer select IBM System x blades running Linux onSystem x in the IBM zEnterprise BladeCenter Extension Model 002 1 .Question:What did IBM announce on February 15, 2011 for IBM System z?Answer:On February 15th, IBM announced the IBM WebSphere DataPower Integration Appliance XI50 for IBMzEnterprise (DataPower XI50z), delivering on our statement of direction in the July 22, 2010zEnterprise System (zEnterprise) announcement. The DataPower XI50z appliance is a multifunctionalappliance that can help provide multiple levels of XML optimization, streamline and secure valuableservice-oriented architecture (SOA) applications, and provide drop-in integration for heterogeneousenvironments by enabling core Enterprise Service Bus (ESB) functionality, including routing, bridging,transformation, and event handling. It can help to simplify, govern, and enhance the network securityfor XML and Web services.When the DataPower XI50z is installed within the zEnterprise environment, zEnterprise UnifiedResource Manager will provide integrated management for the appliance to simplify control andoperations including change management, energy monitoring, problem detection, problem reporting,and dispatching of an IBM System z Service Representative as needed.Question:What did IBM announce on July 22, 2010 for IBM System z?Answer:On July 22nd, IBM introduced the IBM zEnterprise System - a system that combines unprecedentedinnovations to the gold standard of enterprise computing with new, built-in functions that extend manyof IBMs leading mainframe-like governance and qualities of service even further to specializedapplication optimizers and select POWER7 and IBM System x 2 blade servers, to simplify operationsacross all these application environments. IBM also introduced the IBM zEnterprise Unified ResourceManager which dramatically simplifies operations across multiple application environments. TheUnified Resource Manager provides energy monitoring and management, goal-oriented policymanagement, increased security, virtual networking, and information management, all consolidatedinto a single easy-to-use interface firmly grounded in real-world business requirements. The IBMzEnterprise System includes the z196, the Unified Resource Manager, the IBM zBX, and integratedoptimizers and/or IBM blades. IBM also announces strategic software and services innovations for theIBM zEnterprise System that help many more customers solve critical problems that were impossibleor unaffordable to solve with any previous technologies, in areas such as business analytics andinsight, accelerating new business function delivery, auditing and risk reduction, and business processoptimization, among others.1 System x blades on the zEnterprise were a Statement of Direction in July 2010. With the announcement on July 12, 2011 we are announcing support forthe System x blade within the zBX.2 System x blades on the zEnterprise were a Statement of Direction in July 2010. With the announcement on July 12, 2011 we are announcing support forthe System x blade within the zBX. 5
  6. 6. Question:What part does the IBM zEnterprise System play in a “Smarter Planet™”?Answer:Businesses and governments need smarter systems and software for enterprise computing and forrobust cloud environments. They must unify and optimize multiple systems to work as a single,integrated service delivery platform to address real-world business problems in real time. They needto scale without adding complexity to meet ever-growing demands on infrastructure. They need vastlysimplified data center management that slashes space, power, and cooling requirements to respectboth their budgets and our planet. They need to move well beyond business-as-usual to transform ITinto the leading catalyst for continuous business growth and innovation. And they must do all thatwhile improving service qualities: eliminating business interruptions for any reasons (includingsoftware and application upgrades), preventing security breaches, assuring customer privacy, andreducing enterprise risk.With these accomplishments we can all live on a "Smarter Planet." In July 2010, System z introducedthe smartest technologies ever created that will help customers meet and exceed these challenges:the new IBM zEnterprise System. The zEnterprise System is a “System of Systems,” integrating IBM’sleading technologies to dramatically improve the productivity and quality of today’s multi-architecturedata centers and tomorrow’s clouds. The z196 is the world’s fastest and most scalable enterprisesystem with unrivaled reliability, security, and manageability as well as the industry’s most efficientplatform for large-scale data center simplification and consolidation. The new z114, introduced in July2011 offers a new design point, new packaging, more flexibility and granularity, and improved priceperformance.Question:What are the three layers of management function in System z hardware, software and servicesarchitecture?Answer:The new management functions IBM is introducing fit into three categories, or layers. Each layerenhances the business value of workloads whether they are running in one or in some combination ofapplication environments. All the layers are transparent to the applications and do not requireapplication programming or other special action to exploit. The three layers are: Hardware management – Capabilities designed to discover, configure, virtualize and manage the basic system hardware and networking resources of multiple processor families from a single, consistent point of control. Platform management – Capabilities designed to manage the lifecycle and operational characteristics of virtualized runtime environments in support of several application architectures, driven by a workload context that is independent of the underlying architectures. Service management – Capabilities designed to align the management of IT with business goals, provide IT service management and automation, incorporate software and process management, handle multi-site IT operations and multi-ensemble management scope. 6
  7. 7. Question:Is IBM positioning the zEnterprise System replace all servers in the entire data center? Should Iconsider moving all my applications that run on UNIX® to the zEnterprise?Answer.In most cases no, IBM is not yet quite that ambitious! There are different servers because the worldneeds different servers. However, the zEnterprise System can indeed “replace” the end-to-endinfrastructure for a large collection of multi-environmental enterprise applications. Specifically,enterprise customers with one or more applications that are currently running in a complex,heterogeneous, multi-tiered environment now have the opportunity to upgrade that infrastructure withzEnterprise and enjoy the management benefits that the Unified Resource Manager brings. The zBXsupports scores of blades running hundreds or even a thousand virtual servers, and the z196 deliversunprecedented opportunities for enterprise simplification that build upon the well-known strengths ofSystem z.Many of the largest data centers already have far more blades and/or rack-mounted servers in theirinventory than could realistically fit into the zBX. However, IBM expects that current System zcustomers will (and should) start to bring particular end-to-end enterprise applications onto zEnterprise,particularly those where there are affinities between the application components and System z-basedapplications and information. Customers can then manage these end-to-end applications in commonways and achieve higher service qualities and reduced costs. And with the new z114, IBM is targetingnew zEnterprise customers that may never have had System z in the past. They, too, will benefit fromzEnterprises end-to-end application management as they move the application componentsrepresenting many whole business processes onto the zBX. For both new and existing customers,zEnterprise represents a breakthrough in IT simplification and, combined with IBMs other serverofferings, the most potent and sophisticated data center consolidation and simplification portfolio in theindustry for even the worlds largest data centers.Question:What kind of cloud computing options do I have with zEnterprise?Answer:IBM System z has provided superior levels of cloud infrastructure support for decades. This includesextreme levels of resource sharing, sophisticated virtualization technology, rapid provisioning of virtualservers and applications, the highest levels of application availability and efficient operational andmanagement support. With z/VM® and zEnterprise, customers can run virtual servers for less than $1each day when hosting workloads that achieve high levels of consolidation and scale while enjoyingthe other cost savings and service quality improvements. IBM Tivoli products including TivoliProvisioning Manager, Tivoli Service Automation Manager, and Tivoli OMEGAMON® XE on z/VM andLinux provide even greater levels of automation, control, and service management, helping clientsincrease the productivity of their staff and improve the quality of service offered by a zEnterprise cloud.Also, hosting virtual Linux servers on zEnterprise IFLs is a very efficient and reliable way to leveragethe industry-leading application and information data serving capabilities of z/OS® within a cloudinfrastructure.IBM offers the System z Solution Edition for Cloud Computing and the Smart Analytics Cloud forSystem z. These zEnterprise offerings provide a very cost-attractive packaging of hardware, software,and services to help customers deploy cloud infrastructures for general purpose virtual server hostingand business intelligence respectively. 7
  8. 8. The zEnterprise provides even greater flexibility for cloud computing than “one architecture fits all”alternatives. The inclusion of Power® and IBM System x blades in a zEnterprise System allowscustomers to optimize workload placement in order to more closely align IT spending with businessgoals. The zEnterprise Unified Resource Manager helps IT staff integrate and manage amulti-architecture environment at a platform level, enabling businesses to unlock the value ofworkload-optimized systems without suffering the operational complexity that might be experienced ina non-integrated environment.Question:Will the new zEnterprise System be supported for SAP solutions?Answer:Yes. SAP certifies the database and operating system versions, that means DB2® for z/OS, z/OS,Linux on System z, AIX, etc. The certified versions are listed in the OS/DB Product Availability Matrixfor SAP NetWeaver® (PAM). This certification is valid for any IBM hardware, including the zEnterpriseSystem with the zEnterprise BladeCenter Extension (zBX) running with AIX.Question:What are the planned availability dates for the new IBM zEnterprise 114 (z114) and System xhardware offerings?Answer:IBM plans to start shipping zEnterprise products according to the following schedule:September 9, 2011IBM zEnterprise 114 Models M05 and M10 new buildsMES orders for the following features:IBM System z9® Business Class (z9 BC) 2096 and System z10 BC 2098 model conversions tozEnterprise 114 Models M05 and M10Field installed features and conversions that are delivered solely through a modification to themachines Licensed Internal Code (LIC).Full Hardware Management Console (HMC) support for 9x driverFull Trusted Key Encryption (TKE) support for 7.1 codez114 entitlement features for POWER7, IBM Smart Analytics Optimizer, and DataPower blades on azBXSeptember 26, 2011Manage suite (#0019) enhancements for z196Automate / Advanced Management Firmware Suite (#0020) enhancements for z196Manage Firmware System x Blade (#0042)Advanced Management Firmware System x Blade (#0046)IBM zEnterprise BladeCenter Extension support for select System x blades 8

  11. 11. z114 Hardware OverviewQuestion:What is the relevance of the naming zEnterprise 114 or z114?Answer:zEnterprise, first generation, 14 processors.Remembering back to how the z196 got its name, the z114 is no different. The 1 signaling this is thefirst generation of zEnterprise branded hybrid server technology; and the 14 representing the 14processors that power the system (10 of which are customer configurable).Question:What is new about the z114 processor chip?Answer:The z114 leverages the same microprocessor technology as the zEnterprise 196 (z196) but is tunedand optimized for the processing requirements of the entry-level mainframe.The core CPU design combines all the best qualities of the latest mainframe design philosophy with agenerous infusion of POWER7-inspired computational muscle, a reflection of the teamwork betweenIBMs best processor designers.The new microprocessor chip has a higher-frequency superscalar design, improved cache structure,new “out of order” execution sequence and over 100 new hardware instructions that deliversworld-class per-thread performance for DB2, WebSphere and Linux workloads. For CPU intensiveworkloads, additional gains of up to 25 percent can be achieved via multiple compiler levelimprovements.1The z114 is powered by up to 14 microprocessors running at 3.8 GHz and delivers up to 18 percentimprovement in performance per core compared to its predecessor, the z10 BC.1 The z114 will exhibit up to 25% performance improvement, based on measurements and projections, for CPU intensiveworkloads when accompanied by multiple C/C++ compiler level improvements going from XL C/C++ V1R9 to V1R12Question:What about the z114 makes it so adept for consolidation and infrastructure simplification?Answer:Today, most datacenters contain mainframe and distributed systems, running a diverse set ofworkloads or industry applications. The zEnterprise 114 is designed to help address the complexityand inefficiencies of these silo’ed IT infrastructures.As businesses look to transform their IT infrastructures, many choose to start this journey byaddressing existing inefficiencies by consolidating workloads to lower the cost of operations. System zcan do this on a grand scale. The extreme virtualization capabilities of the z114 can support anaverage of 30 distributed servers or more on a single core depending on the workload, or up tohundreds in a single footprint, delivering a virtual Linux server for under $1.45 day1 and provides anopportunity to help you to collapse infrastructures and drive greater data center efficiencies.Unlike other proclaimed cloud solutions that are defined by a siloed architecture resource pool, thez114 leaps beyond the virtualization of a single platform and can integrate, virtualize and managemultiple server architectures for optimal application placement. You have the flexibility to deploy andmanage applications across a virtualized pool of heterogeneous resources and operatingenvironments including z/OS, z/VM, z/VSE, Linux on System z, AIX, Linux on System x and Windows2. 11

When configured with a zEnterprise BladeCenter Extension (zBX), you can combine System z, UNIXand Intel3 server technologies into a single unified system—integrating workloads with affinity tomainframe applications and data—and with the zEnterprise Resource Manager, manage it all with thesame tools, techniques and resources for consistent, automated and reliable service delivery.The z114 offers a range of scaling capabilities: Scale up—over 3100 general purpose MIPS in a single footprint Scale out—consolidate up to 300 distributes servers Scale within—specialty engines, cryptographic processors, hypervisors Scale beyond its traditional boundaries—when configured with the zBX—supports the integration of up to 112 distributed blade servers and workload optimizers5With improved processor performance, increased capacity, new hybrid computing capabilities, andsignificant power, space and cooling benefits, the z114 is now a genuine “data-center in a box” solutionand a perfect fit for infrastructure simplification and true Cloud Computing.1 Linux on System z virtual servers can be: Less than $1545 for 3 years; Less than $515 per year; Lessthan $1.45 per day. Based on US Enterprise Linux Server pricing. Pricing may vary by country. Modelconfiguration included 10 IFL cores running a mixed workload averaging 31 virtual machines per corewith varying degrees of activity. Includes zEnterprise hardware and z/VM virtualization software. Doesnot include Linux OS or middleware software.2 Statement of direction. All statements regarding IBM future direction and intent are subject to changeor withdrawal without notice, and represents goals and objectives onlyQuestion:What is the machine type of the z114?Answer:The machine type is 2818.Question:What z114 models were announced?Answer:The z114 is available in two models; a single central processing drawer model, the M05 and a twodrawer model, the M10 which offers the additional flexibility for I/O and coupling expansion and/orincreased specialty engine capability. The M05 and M10 are hardware differentiated models unlike theLICCC differentiator on z9® BC. With up to 10 configurable cores, the model naming is indicative ofhow many total processor units are available for customer purchase and characterization.The cores can be configured as general purpose processors (CPs), Integrated Facilities for Linux(IFLs), System z Application Assist Processors (zAAPs), System z Integrated Information Processors(zIIPs), Internal Coupling Facilities (ICFs), additional System Assist Processors (SAPs), or used asadditional spares. And on the M10, you can have up to two “dedicated” spares as well, a first for themidrange product offering.With up to 5 CPs and 130 available capacity settings offered across either model, you have thefreedom to choose the right capacity setting for your needs with the flexibility to scale on demand asworkload demands increase.And we offer both IFL only and ICF only configurations where you can have up to 10 IFLs or ICFs in astandalone environment. 12
  13. 13. Question:How much memory is available on the z114? What is the RAIM feature you mentioned earlier?Answer:The z114 supports up to 256 GB of customer purchased real (usable) RAIM-protected memory—anindustry exclusive currently available only on System z. Beyond the 248 GB of “customer purchasablememory,” there is an additional 8 GB of memory for the Hardware System Area (HSA) which holds theI/O configuration data for the server.The minimum initial amount of memory that can be ordered is 8 GB on the Model M05 and 16 GB forthe Model M10. Memory can be ordered in increments of 8 or 32 GB.The z114 and z196 are the only high-end servers in the industry to offer the redundant array ofindependent memory (RAIM) technology. RAIM is similar to what is known in the disk storage industryas RAID. RAIM technology provides protection for the dynamic random access memory (DRAM), dualinline memory modules (DIMMs), and at the memory channel level, delivering the most resilientmemory subsystem to date. RAIM is always active, and IBM has already factored internal RAIMoverhead into all advertised memory configuration amounts.Question:Why did you introduce a 2 model packaging structure and what are the differences between the M05and M10?Answer:We have basically halved the resources of the z10 BC processor drawer and split them into twoseparate containers if you will, to make a more cost effective entry level solution for clients that don’tneed the full resources of a fully configured machine. So where on the z10 BC we had 4 Single ChipModules (10 configurable engines) and 2 Storage Control Modules which are your level 4 cache and20 DIMMs for memory, we have now essentially split them so the resources are spread across 2drawers on the z114 with each drawer separately containing 2 SCMs, 1 Storage Control Module and10 DIMMs for memory. This allows us to avoid shipping and charging for unnecessary technology thatsome clients will never need or use.It is important to select the appropriate model for your processing needs. Other than just for capacity orfor raw engine count, there are other variables or reasons that may dictate the need for an M10 suchas: When you require more than 5 total processor units (mix of CPs or specialty engines) or are on the verge today and want to be able to grow non-disruptively into the M10 (e.g. you are on a 4 way today and want the ability to add more the one specialty engine in the future If you need more than 128 GB of memory offered on the M05 you can get up to 248 GB of customer usable memory on the M10. There is a limit to the amount hub slots and bandwidth that is available with the 1 drawer system (M05) and if you exceed that bandwidth or need additional I/O capability or for increased coupling link requirements then the 2nd drawer (M10) will be needed. 13

Unused or unassigned engineson either the M05 or M10 can be used as spares.Question:Can either of these ‘dedicated’ IBM provided spare processing cores be used for other purposes?Answer:No, these spares are exclusively reserved to provide failover in the extremely unlikely event of aprocessor failure. The spare cores protect all processor types (CPs, IFLs, zAAPs, zIIPs, and ICFs).Any additional spares or unassigned cores can be activated for other purposes within the limits of theallowable configuration. 14
  15. 15. Question:How many System Assist Processors (SAPs) are on the z114?Answer:2 System Assist Processors (SAPs) are standard on both the model M05 and M10. Additionally, moreSAPs may be acquired from the pool of available processing units within the model.Question:Have you made improvements to the just-in-time deployment of capacity on z114?Answer:Yes. Please see the capacity on demand section of this FAQ document.Question:Is the z114 physically bigger than the System z10 BC?Answer:No, the z114 is actually physically smaller than the z10 BC with a 9 inch reduction in depth. Althoughthe product dimensions are slightly smaller, the z114 still requires the same floor cutouts as the z10 BCIf you choose the top-exit cabling option, the clearance requires an additional 6 inches to the width ofthe standard z114.Below are is a summary of the Physical Configuration requirements for both models of the z114.

Also,there are some changes to licensing of certain firmware in a zEnterprise System. First, firmware forthe z114 cryptography feature includes technology that requires license terms in addition to thestandard license terms governing use of LIC, so an addendum to the LIC license will be included whena z114 is configured with a crypto card feature having elliptical curve cryptography capabilities.Second, certain zBX components and features include firmware that is licensed under non-IBM terms(called "separately licensed code" or "SLC"). IBM will deliver the license agreements governing use ofSLC along with the IBM license agreement for LIC when a zBX is ordered. 15
  16. 16. Question:What is the maximum allowable distance between the z114 frame and the zBX frame?Answer:The controlling z114 must be connected to the zBX with a 26 meter (85’) cable. This requirement is forserviceability reasons.Question:If I order a z114 with the non-raised floor (NRF) option, can I also order a zBX with a NRF option?Answer:Yes. Both the z114 and zBX support NRF implementations.Question:What cooling options are available for the z114 and the zBX?Answer:The z114 is a single frame, air cooled system only. Water cooling is not an option for the z114, like it ison the z196.For the zBX there is an optional rear door heat exchanger available.Question:Is it possible to update driver code on the zBX separately from the z114, on a different schedule?Answer:No. Once the zBX is installed the firmware is common and updated as a unified zEnterprise system.Question:Can I buy a z114 that has only IFL or ICF processors without including a general-purpose processor(CP)?Answer:Yes. Similar to the System z10 BC, you can order only IFLs or ICFs in a z114, using a model capacityidentifier of A00 with 1 to 10 IFLs or ICFs.Question:Does the z114 offer the same hybrid capabilities as the z196?Answer:Yes. The z114 offers the exact same hybrid computing capabilities as the z196. The z114 simplyrepresents a new entry point into the hybrid computing model for mid-sized clients.When we are talking about hybrid computing and the introduction of the z114, its important to realizethat the central processing complex can be either the z196 or now the z114. It’s the only componentthat is different or interchangeable based on the size and capacity requirements of the mainframefootprint. 16
  17. 17. The entire hybrid environment is equally accessible to the z114 client as the z196 provides. There areno limitations in terms of what you can put in a zBX or how Unified Resource Manager works whenyou’ve got a z114 vs a z196 in the mix. It is not kneecapped in ay way. It uses the same zBX, the sameblades, optimizers and operating environment support, and the same Unified Resource Managerfirmware. Everything we will talk about regarding hybrid computing applies equally to a z114 and z196environment.Question:Is the z114 just a high end derivative of the z196?Answer:The z114 offering features many of the leadership capabilities of the z196 in a package that isdesigned for mid-sized businesses, bringing hybrid computing within the reach of a much broader setof clients. The new z114 is much more than just a high end derivative. While it boast similar qualities ofservices, what we built was unique for the mid-sized business – new design point, new packaging,more flexibility and improved price performance are just a few of elements of the new design. 17
  18. 18. z196 HardwareQuestion:What is new about the z196 processor chip?Answer:The z196 represents the worlds finest microprocessor engineering. This new CPU combines all thebest qualities of the latest mainframe design philosophy with a generous infusion of POWER7-inspiredcomputational muscle, a reflection of the teamwork between IBMs best processor designers. Whenconsidering all-important single threaded operations, the new z196 processor chip is quite simply thefastest processor on the market today. At 5.2 GHz, the z196 is also the highest clock speed serverCPU ever created in all of computing history to date. The z196 microprocessor delivers astonishinglevels of performance also achieved through: New Out-of-Order instruction execution provides improved throughput across a broad range of workloads while preserving and extending the mainframe’s strength in delivering predictable, reliable, assured processor results. In particular, Out-of-Order execution yields significant improvements for compute-intensive applications dramatically increasing the breadth and scope of mainframe computing in areas such as real-time business analytics. There are 100 new instructions added to improve compiled code efficiency. Again, CPU-intensive applications should benefit the most, including applications written in C++ on z/OS. There are an unprecedented four levels of cache in the CPU packaging. Compared to the industry’s previous reigning cache leader, the IBM System z10® Enterprise Class (z10 EC™), there is more than twice as much on-chip cache memory and four times as much shared cache per processor book. This rich shared-cache structure is particularly optimized for the enterprise information serving workloads, mixed application workloads with high rates of context switching, and pervasive virtualization workloads which are mainframe hallmarks and which provide the strongest possible foundation for maximum cloud computing efficiency. There is also a substantial performance improvement for multiprocessor systems with a large number of cores (over 30) even compared to the already leading System z10. Like the z10™, there are on-chip hardware accelerators for compression, encryption, decimal floating point, and other important aspects of business computing, but these accelerators run even faster and support more algorithms directly in hardware. Moreover, each pair of cores shares a coprocessor for data compression and cryptographic functions, to improve throughput and to help keep all cores maximally focused on productive business computing. Even with all these improvements and amazing performance attributes, the overall result is a system with more cores and even more performance while holding the line on data center space, power, and cooling requirements. That means the z196 CPU delivers market-leading performance with market-leading efficiency. 18
  19. 19. Question:What about the z196 makes it so adept at for consolidation of server farms?Answer:Scale is the first big factor making the z196 so compelling for consolidating distributed servers. The5.2 GHz chip means more processing power per core, and there are lots more cores available in eachframe – up to 80 “visible” cores per server but many more helping to keep those 80 focused on realwork. The z196 has a new RAIM (redundant array of independent memory) structure that deliversdouble the amount of useable memory over the z10 EC (now 3.0 TB, up from 1.5 TB) with muchgreater memory reliability.The use of integrated blades offers an added dimension for workload consolidation and optimization.And Unified Resource Manager governs Linux on System z and blade resources for greater commandand control.Question:What is the machine type of the z196?Answer:The machine type is 2817.Question:What z196 models were announced?Answer:IBM announced the following z196 models. Please note that the last two digits of the model numberindicate the maximum number of processor units (PUs) available for customer purchase on thatmodel.A z196 M15 model can be a 1-way through 15-way – which means there are 15 orderable corescontained on one processor “book” (plus many supporting cores in every model, including a minimumof two spare cores).A z196 M32 model can be a 1-way through 32-way (32 orderable cores) contained on two books.A z196 M49 model can be a 1-way through 49-way (49 orderable cores) contained on three books.A z196 M66 model can be a 1-way through 66-way (66 orderable cores) contained on four books.The enhanced capacity z196 M80 model can be a 1-way through 80-way (80 orderable cores)contained on four books.Customers that reach book limits can easily upgrade from smaller models to larger models (except theM80) nondisruptively, i.e. without requiring a service interruption of the machine.The cores can be configured as general purpose processors (CPs), Integrated Facilities for Linux(IFLs), System z Application Assist Processors (zAAPs), System z Integrated Information Processors(zIIPs), additional System Assist Processors (SAPs), Internal Coupling Facilities (ICFs) and/or used asadditional spares.Up to fifteen subcapacity CPs can be active on the server regardless of hardware model. In otherwords, subcapacity configurations are available on any of the models (M15 to M80) as long as theserver is configured (not necessarily the same as purchased) with fifteen or fewer general-purposeprocessors. 19
  20. 20. Question:Does the z196 offer more available subcapacity processors than the z10 EC?Answer:Yes. The z196 can have up to 15 subcapacity Central Processors (CPs) per server while thez10 EC accommodates up to 12 subcapacity CPs. These subcapacity processors can physicallyreside in multiple books. These additional subcapacity options provide customers with the flexibility tomatch their infrastructure to their business volumes at every moment in time, to improve operationalefficiency.Question:How much memory is available on the z196? What is the RAIM feature you mentioned earlier? Will Istill have a 16 GB HSA?Answer:The z196 server supports up to 3 TB of real memory per server and 1.0 TB per LPAR, but the actualmaximum physical memory sizes are related to the number of books in the system. The minimuminitial amount of memory that can be ordered is 32 GB for all models.The z196 is the first and only high-end server in the industry to offer redundant array of independentmemory (RAIM) technology. RAIM is similar to what is known in the disk storage industry as RAID.RAIM technology provides protection for the dynamic random access memory (DRAM), dual inlinememory modules (DIMMs), and at the memory channel level, delivering the most resilient memorysubsystem to date.Please note that the 3 TB maximum memory is customer-usable, RAIM-protected memory. RAIM isalways active, and IBM has already factored internal RAIM overhead into all advertised memoryconfiguration amounts.IBM still provides 16 GB of HSA in every z196, independent of customer-purchased memory.Question:What is different about the Model M80 compared to M66?Answer:The Model M80 is an enhanced capacity model which contains a different configuration of MCMs thanother models. The z196 is fully populated with four high density books and 80 orderable cores. Youcan configure the M80 machine to be a 1 to 80-way. Like the other four-book model, the M66, the M80can be ordered with a minimum of 32 GB of memory and up to a maximum of 3 TB.Upgrading from any other model of the z196 to a Model M80 will require a planned outage of thatmachine, but you can still avoid application service interruptions if you exploit Parallel Sysplex® whichcan automatically and dynamically shift workloads to another machine.Question:How many spare processing cores are on the z196?Answer:IBM ships every z196 machine with a minimum of two spare processing cores. These spares can beshared across the books. The z196 offers core-level (engine-level) level sparing. 20
  21. 21. Question:Can any of these spare processing cores be used for other purposes?Answer:No, the minimum allotment of spare cores are exclusively reserved to provide failover in the extremelyunlikely event of a processor failure. The spare cores protect all processor types (CPs, IFLs, zAAPs,zIIPs, and ICFs). Any additional spare cores above the minimum allotment can be activated for otherpurposes.Question:How many System Assist Processors (SAPs) are on the z196?Answer:The answer depends on the model. The standard number of SAPs provided to the customer is asfollows:The z196 Model M15 has three.The z196 Model M32 has six.The z196 Model M49 has nine.The z196 Model M66 has twelve.The z196 Model M80 has fourteen.These are in addition to the "visible" customer configurable cores. For example, an M80 has 14 SAPs,2 mandatory minimum spare cores, and up to 80 customer configurable cores.Additionally, more SAPs may be acquired from the pool of available processing units within the model.Question:Have you made improvements to the just-in-time deployment of capacity on z196?Answer:Yes. Please see the capacity on demand section of this FAQ document.Question:Is the z196 physically bigger than the System z10 EC?Answer:No, the z196 has the same floor cutouts as the z10 EC. If you choose optional water cooling or top-exitI/O cabling the clearance is be different (4” additional depth for water and 12” width for top-exit I/Ocabling) from the standard z196.Question:Can you help me understand the firmware implementation of z196?Answer:In general, z196 and zBX firmware is implemented in the traditional System z manner. What is differentis that firmware (for example, the hypervisors) for blades installed in a zBX are supported from theattached z196 firmware, to help optimize the integration of the zBX with the z196, as well as treatingthe blade firmware as an "always there" component of the zEnterprise System. Also, there are somechanges to licensing of certain firmware in a zEnterprise System. First, firmware for the z196cryptography feature includes technology that requires license terms in addition to the standardlicense terms governing use of LIC, so an addendum to the LIC license will be included when a z196 isconfigured with a crypto card feature having elliptical curve cryptography capabilities. Second, certainzBX components and features include firmware that is licensed under non-IBM terms (called 21
  22. 22. "separately licensed code" or "SLC"). IBM will deliver the license agreements governing use of SLCalong with the IBM license agreement for LIC when a zBX is ordered.Question:What is the maximum allowable distance between the z196 frame and the zBX frame?Answer:The controlling z196 must be connected to the zBX with a 26 meter (85’) cable. This requirement is forserviceability reasons.Question:What cooling options are available for the z196 and the zBX?Answer:For the z196 there is optional water cooling available. For the zBX there is an optional rear door heatexchanger available.Question:Is it possible to update driver code on the zBX separately from the z196, on a different schedule?Answer:No. Once the zBX is installed the firmware is common and updated as a unified zEnterprise system.Question:Can I buy a z196 that has only IFL or ICF processors without including a general-purpose processor(CP)?Answer:Yes. Similar to the System z10 EC, you can order only IFLs or ICFs in a z196, using a model capacityidentifier of 700 with 1 to 80 IFLs or a maximum of 16 ICFs. 22
  23. 23. z196 and z114 AvailabilityQuestion:What availability enhancements are provided on the z196 and z114?Answer:With the introduction of the IBM zEnterprise 196, IBM continues to deliver enterprise reliability andavailability with enhancements to the memory subsystem, multichip module (MCM) and power deliverytechnologies. The z114 is built using IBM’s SCM (single-chip module) design which hosts the newlydesigned CMOS 12S processor units, storage control chips and connectors for I/O. Both designs offerencapsulated processor unit connectors and soft error rate (SER) hardened latches throughout thedesign.The industrys most robust memory error detection and correction architecture to date is found in thezEnterprise server’s new memory subsystem. A new redundant array of independent memory (RAIM)technology provides protection at the dynamic random access memory (DRAM), dual inline memorymodule (DIMM), and memory channel levels. IBMs RAIM technology can correct three full DRAMfailures per rank. DIMM level failures, including components such as the memory controllersapplication specific integrated circuit (ASIC), the power regulators, the clocks, and the board, can allbe corrected. Memory channel failures such as signal lines, control lines, and drivers/receivers on theMCM can be corrected, too. Upstream and downstream data signals can be spared using two sparewires on both the upstream and downstream paths. One of these signals can be used to spare a clocksignal line (one upstream and one downstream). Together these improvements are designed to deliverthe most resilient memory subsystem to date.Since data center environmental deviations are becoming more common and can quickly disruptoptions if undetected and unchecked, IBM has increased self-protection capabilities on the zEnterprisefamily of servers. IBM includes voltage transformation module (VTM) technology with tripleredundancy on the VTM. This redundancy protects processor workloads from loss of voltage due toVTM failures. Humidity and altitude sensors are also triple redundant, for increased reliability.Both the z196 and z114 offers the new hot pluggable PCIe I/O drawers and I/O drawers, redundant I/Ointerconnect, and concurrent PCIe fanout and Host Channel Adapter (HCA-O and HCA-C fanout cardhot-plug.Of course, the z196 and z114 also inherit the already industry-leading availability characteristics of theSystem z10 design.Question:Will the z196 and the z114 still offer Plan Ahead Memory?Answer:Yes. Plan Ahead Memory allows future memory upgrades to be preplanned and installednon-disruptively. The preplanned memory feature adds the necessary physical memory required tosupport target memory sizes. If you anticipate an increase in memory requirements, a "target" logicalmemory size can now be specified in the configuration tool along with a "starting" logical memory size.The configuration tool will then calculate the physical memory required to satisfy this target memory.Should additional physical memory be required, it will be fulfilled with the preplanned memory features.Activation of any preplanned memory requires the purchase of preplanned memory activation features.You can activate memory to any logical size offered between the starting and target size. 23
  24. 24. Question:Will the z196 offer the flexible memory option?Answer:Yes. Flexible memory was introduced on the z9 EC as part of design changes and offerings to supportenhanced book availability. Flexible memory provides the additional resources to maintain a constantlevel of memory when replacing a book. On the z196, the additional resources required for the flexiblememory configurations are provided through the purchase of preplanned memory features along withthe purchase of a memory entitlement.The flexible memory option is not available on the z114.Question:How is Flexible memory different than the Plan Ahead memory?Answer:Flexible memory provides a constant level of memory when you are replacing a book on the system.Thus it is used during a repair action. On the other hand, Plan Ahead memory is pre-plugged in theanticipation of wanting to increase memory non-disruptively at some point in the future. Memory ispre-plugged based on the target capacity. 24
  25. 25. zBX Hardware and associated featuresQuestion:What is the hardware machine type of the zBX? Is there a machine type for the optimizers and bladesinstalled in the zBX?Answer:The zBX machine type is 2458 Model 002. IBM Smart Analytics Optimizer is ordered as a feature ofthe 2458. POWER7 and System x blades are ordered independent of the zBX (see the POWER7 andHX5 7873 section of this document for details). DataPower XI50z is ordered as a feature of the zBXbut will generate machine type 2462 Model 4BX.Question:If I have four zBX racks connected to one z196 or z114, is that considered one zBX or four zBXs?Answer:IBM considers that configuration to include one zBX with four racks. Customers can order one optionalzBX per z196 or z114 server, and the zBX can include one, two, three, or four racks.Question:If I have more than one rack in the zBX are they bolted together?Answer:Yes IBM offers ‘marriage kits’ in the ship group if you have more than one frame. These bolt theframes together.Question:Is there anything that I will need to customize on the BladeCenter Chassis?Answer:No. The zBX is a totally integrated system. The only thing that is different per installation is that acustomer decides which blades they put into the zBX – either IBM Smart Analytics Optimizer,DataPower XI50z or select POWER7 or System x blades.Question:How many z196s or z114s can connect to a zBX?Answer:A combination of up to eight z196s or z114s can connect over the intra-ensemble data network (IEDN)to one zBX, but only one z196 or z114 “owns” the management and support connection. 25
  26. 26. Question:What is the physical size of the zBX?Answer:It depends on what size zBX is ordered. Customers can order one to four zBX racks depending uponthe number of optimizers and blades required. The first rack will be a standard 42u 19” sized rack andthe rest will be 42u 19” expansion racks. Customers can request a 36u height reduction option ifneeded. There are 2 to 4 power distribution units (PDU) and 2 to 4 60A line cords per rack. Rear doorheat exchanger and acoustic doors are optional.Question:How much time will it take to load the firmware on the blades using a zBX?Answer.It depends. There will be some difference based on the configuration. Firmware load times can rangefrom a few minutes to several hours.Question:What if I put a supported blade in the zBX that has data on it already?Answer:When the supported blade is discovered and configured it will be loaded, and the zBX will wipe theBIOS level clean so any data will be removed – including any Machine Code that was on the blade.Question:If you have a zBX Model 002 with four frames, are there top-of-rack (TOR) switches in each frame?Answer:No, TOR switches for management and data are only in the first frame, so all zBX-002 networkconnectivity flows through those switches.Question:If I have more than one frame in the zBX are they bolted together?Answer:Yes, IBM offers “marriage kits” in the package for customers ordering more than one frame. These kitsbolt the frames together using standard tools.Question:If I order a z114 with a non-raised floor (NRF), can I also order a zBX with a NRF option?Answer:Yes. Both the z114 and zBX support NRF implementations. 26
  27. 27. Question:Will I be able to mix supported blades and optimizers in the same chassis within a zBX?Answer:It depends. The BladeCenter PS701 Express and BladeCenter HX5 blades and DataPower XI50z canshare the same BladeCenter chassis — note that DataPower XI50z blades are “doublewide” and usetwo slots. They can be mixed in the same zBX with IBM Smart Analytics Optimizer blades—but not inthe same BladeCenter Chassis. Total zBX capacity can not exceed 112 total blades.Question:Why can’t I mix general-purpose blades or DataPower XI50z blades and IBM Smart Analytic Optimizerblades within the same chassis?Answer:The IBM Smart Analytics Optimizer has certain technical requirements for setting up control andworker nodes that demands this uniformity within the same chassis.Question:Why are there only two BladeCenter chassis per zBX frame?Answer:The maximum power that a rack can support is 240amps. Two BladeCenters, fully configured inaccordance with the zBX infrastructure and the redundancy requirements, could reach this limit.Additionally, as the zBX is shipped as a single unit, more than two BladeCenters would exceedshipment tilt and weight limitations.QuestionWhat is the benefit of have a zBX compared to blades installed in a BladeCenter H?Answer:There are several benefits of using the zBX. One is the high speed 10 Gb layer2 network that isconfigured for high availability and secured by the Unified Resource Manager. The connectivity canreduce latency and overhead and potentially remove the requirement for additional hardware(specifically firewalls). Another benefit is the Unified Resource Manager, which provides uniformity ofmanagement tasks, independent of server type or operating system. The system administrator usesUnified Resource Manager to set up new virtual servers in the same way, independently of theoperating system and the hardware.Question:Can an IFL-only server (z196 model capacity identifier 700 or z114 model capacity identifier A00) runUnified Resource Manager with a zBX attached?Answer:The Unified Resource Manager does not require a specific configuration or operating system, so anIFL-only server is compatible with the zBX. 27
  28. 28. Question:What is the configuration of the BladeCenter chassis in the zBX?Answer:All the blades are virtualized, so the underlying hardware is never material for management andprovisioning. The BladeCenter chassis is part of the configured hardware that comes with the zBXorder. When an order is placed, depending on the number of blades specified in the configurator youplan to install, the required hardware is placed into the zBX. This also means that when you want toupgrade the zBX to add additional blades, or optimizers, the z configurator (eConfig) will do thatplanning work again and the resulting configuration will have the necessary hardware.The components of the BladeCenter chassis are not managed independently either. The operationalcontrols provided on the z196 by the Unified Resource Manager enable the underlying hardwareinfrastructure components to be managed transparently to the user.Question:Is the Unified Resource Manager the mechanism for managing the BladeCenter chassis and its I/Omodules?Answer:Yes. Using the Unified Resource Manager (part of the enhanced management suite) you define thevirtual server2. All aspects of a virtual server can be defined – CPU, memory, network, console, diskstorage, and virtual DVD – taking into account differences in the underlying capabilities. (For examplea virtual DVD is not supported for a z/VM-based virtual server). In addition, virtual guests can be listed,started and stopped, reconfigured, and deleted when no longer required. A virtual server definition canalso be moved from one hypervisor to another of the same type.You also define workloads. A workload is a logical grouping of physical and virtual resources withinthe context of named business processes. When you set up a workload you will assign the virtualservers, storage and network (VLANs) resources that you want to make available to the workload.Question:What workloads are good candidates to run on the zEnterprise System?Answer:The zEnterprise provides the opportunity to bring together most or all of the application and informationcomponents of important end-to-end business applications into one unified, simplified, and easilymanaged server environment. Strong candidates for zBX hosting include application components withaffinities to System z application and information services. Such applications are found in everyindustry, including banking, insurance, retail, government, and manufacturing. Some of the candidateworkloads include business intelligence, data warehousing, business analytics, ERP (including SAPapplications), CRM, infrastructure services (such as monitoring, storage management, and securityservices), Web serving, and other multi-tier application architectures. The zEnterprise also offers newopportunities for recentralizing enterprise information (for improved governance and customer privacyprotection), master data management, and enterprise reporting.IBM System z representatives can meet with prospective zEnterprise customers and use a newassessment tool to identify the strongest application candidates and determine the business value thatzEnterprise delivers. Please contact an IBM representative for more information. 28
  29. 29. Question:Today I have WebSphere Application Server running on distributed servers, and Ive been consideringmoving at least some of those applications to the mainframe. Should I move my applications toWebSphere Application Server for z/OS, WebSphere Application Server for Linux on System z, or to azBX blade?Answer:It depends. For example, if your applications have close affinity to z/OS-based information and/orapplications, or require the highest service qualities, hosting them on WebSphere Application Serverfor z/OS is likely the best strategy. If z/OS affinity is less important, or if there are particular affinitieswith Linux or AIX (operational or otherwise), System z Linux, System x blades or AIX blades may makethe most sense. In some cases the best choice may be to run WebSphere Application Server on allthree operating systems.IBM offers "Fit for Purpose" workshops to review your IT architectures and make recommendations forserver platform placement. Please ask your IBM representative for more information.Question:I am a user of a large ERP application and have been running it on System z for a long time. I havemigrated everything in my entire shop over to System z and now run DB2 for z/OS, severalapplications on z/OS, all my ERP application servers on Linux on System z, and some otherapplications on Linux on System z. The few exceptions to our general deployment strategy consist ofsome third party applications. The application vendors do not support their products on System z, butthe applications are critical to our business. I think these applications would be good candidates for azBX blade solution. Correct?Answer:Yes. The zBXs System x or POWER7 blades provide an excellent option for such applications, andcustomers can use them to consolidate applications that do not yet run on Linux on System z or onz/OS.Customers should also ask their vendors for the solution attributes they need, including support fortheir preferred platforms. Through its PartnerWorld® program, IBM welcomes and assists vendors inbringing their applications to more operating systems, including Linux on System z and z/OS. In thisway, vendors can expand their market opportunities, increase customer satisfaction and retention, andthus grow their revenues and profits. Typically the effort required is minimal, and IBM is happy to workwith vendors to help them achieve these goals.Question:Are there any zBX-based applications tested with the zBX?Answer:There is no such thing as a “zBX-based application” per se. The IBM Smart Analytics Optimizer is anoptimizer that runs completely under the control of DB2 for z/OS, so there is no application-relateddependency nor are there customer-installed applications on the optimizer. The POWER7 blades, orSystem x blades, installed in the zBX are exactly the same POWER7 orSystem x blades installed in any other BladeCenter chassis and are interchangeable. Naturally, thosePOWER7 blades run the same AIX operating system and the System x blades run the same Linuxoperating system. There is no difference in the blades or in the core chassis, by design. 29
  30. 30. However, applications running on the zBX-based blades enjoy several benefits: easy-to-usemanagement with the Unified Resource Manager, reduced infrastructure complexity, and closerproximity to the System z workload components.Question:If I have spare room in the zBX can I put blades in there that are not controlled by Unified ResourceManager?Answer:The current design point of the zBX, and a very important one from a control/mgt point of view, is ablade in a zBX must be managed by the Unified Resource Manager. We do not have an option for anon-managed zBX blade.Question:What is the maximum number of blades I can put in the zBX?Answer:The total capacity of a zBX can not exceed 112 total blades and can be a all of one kind or acombination. POWER7 can support up to 112 blades, System x can support up to 28 blades,DataPower XI50z can support up to 28 blades and IBM Smart Analytics Optimizer can support up to 56.The blades for POWER7, System x and DataPower XI50z can be shared in the same BladeCenterchassis. Remember that DataPower appliance blades are “doublewide” and use two slots. Theseblades can be mixed in the same zBX with IBM Smart Analytics Optimizer blades—but not in the sameBladeCenter Chassis.Question:Id like to be prepared to install System x blades when they become available. Can I order a zBX withno blades in it and have it ready to go?Answer:Nothing has changed and the order process that exists today remains in place. A zBX order mustinclude entitlement for the blades on the z196 - and until September 26th, entitlements on the zBX areNOT available for the System x blades. Although you can order POWER7 blades today, the POWER7entitlements will not be transferable to System x blades.Question:After you announce them, if I have a rack with supported System x blades installed in it, such as anexisting BladeCenter H, can I integrate those existing blades into a zBX so they can become part ofzEnterprise?Answer:When we formally announce support, if the blades you own match the published model andconfiguration specifications for integration into the zBX, those blades can be installed into the zBXthrough the standard defined processes (including getting entitlements).NOTE: You cannot install an existing BladeCenter H chassis in the zBX. 30
  31. 31. Question:Does IBM System z plan to implement new blades and chassis in the zBX as they become available?Answer:We will need time to test and confirm support for new devices, but our intention is to integrate desirednew technologies into the zBX. 31
  32. 32. POWER7 Blades for zBXQuestion:How do I order the POWER7 blade?Answer:The PS701 Express blade with features and software may be obtained through an IBM BusinessPartner or Distributor, an IBM sales representative, or through http://www.ibm.com. It is recommendedthat you use the following document, posted and continuously updated on the zBX website, for themost current ordering information.http://www.ibm.com/common/ssi/cgi-bin/ssialias?infotype=SA&subtype=WH&appname=STGE_ZS_ZS_USEN&htmlfid=ZSY03019USEN&attachment=ZSY03019USEN.PDFQuestion:Will we have Linux available to run on the POWER7 blades?Answer:No. The POWER7 blades can run AIX 5.3 (Technology Level 12) or later in POWER6® andPOWER6+™ compatibility mode and AIX 6.1 (Technology Level 5) or later. Linux is already availablefor the z196 and a Statement of Direction for IBM System x blades 6 .Question:Which version of PowerVM™ do I need?Answer:You will need to purchase a license for PowerVM Enterprise Edition (EE). You do not need to obtain aphysical copy of the PowerVM software as it will be loaded as System z firmware. Note that when theblade is installed in the zBX and “discovered” by the Unified Resource Manager some PowerVMfunctions, such as Live Partition Mobility, will not be exploited.Question:If I have a rack with POWER7 blades installed in it, such as an existing BladeCenter H, can I integratethose existing blades into a zBX so they can become part of zEnterprise?Answer:If the blades match the published model and configuration specifications for integration into the zBX,those blades are interchangeable and can be installed into the zBX through the standard definedprocesses.NOTE: If the blades are not already licensed for PowerVM Enterprise, and do not have the PowerVMEnterprise activation codes entered, the licenses must be obtained, and the activation codes must beentered before the blades are removed from their current BladeCenter chassis. This is becauseUnified Resource Manager does not provide the User interface to enter the activation codes, so youwill have to enter them in their current BladeCenter environment if you don’t already have thePowerVM EE license/codes on the blades. Additionally, you cannot install an existing BladeCenter Hchassis into the zBX.The following is a link for entering the activation codes in the blades’ existing BladeCenterenvironment:http://publib.boulder.ibm.com/infocenter/powersys/v3r1m5/topic/p7hch/iphchenablevios.htm?resultof=%22%61%63%74%69%76%61%74%69%6f%6e%22%20%22%61%63%74%69%76%22%20%22%63%6f%64%65%22%206 All statements regarding IBM future direction and intent are subject to change or withdrawal without notice, and represents goals and objectives only 32
  33. 33. Question:How is the installation of AIX and the hypervisor managed? Today firmware on a POWER7 blade canonly be updated via an OS installed on the blade or by booting a diagnostic CD. How will this be donein the zBX?Answer:The hypervisors are managed by Unified Resource Manager and are loaded automatically when theblade is ”discovered and configured” within the zBX. The hypervisor will not be accessible to thecustomer. Once a virtual server has been created the customer follows normal operating systeminstallation (AIX) procedures to create a new image.Question:What if the POWER7 blade has more memory on it than the supported configuration?Answer:The blade would be rejected by Unified Resource Manager.Question:What applications can run on the POWER7 blade in a zBX?Answer:Applications that are certified for POWER7 and PowerVM EE are compatible. The same software andhardware environment is provided on the POWER7 blades in the zBX.Question:Will there be separate certification and support statements required for the various middlewareproducts run on the supported AIX?Answer:If middleware or applications run on PowerVM on a POWER7 blade today, then existing supportstatements are sufficient. IBM does not require and does not plan to issue separate certification andsupport statements. IBM has also been working closely with its ISV partners and already hassubstantial feedback that they share the same view.Question:Are the Power blades managed by Systems Director?Answer:No. The zBX blades are managed by the Unified Resource Manager.Question:What are the current allowable configurations of the PS701 blades installed in the zBX?Answer:There are three memory configurations of PS701 BladeCenter Express blades currently supported inthe zBX: 32 GB DIMM, 64 GB DIMM and 128 GB DIMM.Question:What adapters can be ordered on the PS701 blade?Answer:The standard 2port 10 GbE (FC# 8275) and the Fibre Channel Adapter (FC# 8242) must be ordered. 33
  34. 34. They are the only adapters that are supported in the zEnterprise environment.Question:What storage attaches to the POWER7 blades?Answer:A list of supported storage products to support the POWER7 blades can be found on the web at:http://www.ibm.com/common/ssi/cgi-bin/ssialias?subtype=PS&infotype=SA&appname=STGE_ZS_ZS_USEN&htmlfid=ZSP03437USEN&attachment=ZSP03437USEN.PDF. No storage products can be installed in thezBX.Question:Is there a requirement to set up the VIOS? If so, who does that?Answer:VIOS is considered part of the hypervisor, and is therefore managed and delivered by the System zmicrocode update process. VIOS and PowerVM will be automatically installed onto each blade after itis entitled and activated. So, there is no install of VIOS by the customer. Additionally, any of themanual configuration of VIOS that is traditionally performed will no longer be required. To keep VIOSmore stable, there is no external access to it. The Unified Resource Manager will effect the requiredconfiguration changes to VIOS in response to the POWER LPAR definition activities that areperformed on the HMC.Question:Will the POWER7 support PowerHA™?Answer:PowerHA can be configured to perform automated service recovery for the applications running invirtual servers deployed in zBX. PowerHA automates application failover from one virtual server in aIBM System p® blade to another virtual server in a different System p blade with similar configuration.Failover protects service (masks service interruption) in case of unplanned or planned (scheduled)service interuption. During failover, clients may experience a short service unavailability, whileresources are configured by PowerHA on the new virtual server.Power HA configuration for zBX environment is similar to standard Power environments, with theparticularity that it uses only virtual I/O resources. Currently, PowerHA for zBX support is limited tofailover inside the same zBX.IBM PowerHA* Standard Edition (formerly HACMP*) for AIX, V6.1 and V7.1 adds support for the zBX)attached to the z196 or z114. This support is with IBM BladeCenter* PS701 (8406-71Y) Blades.It is recommended to obtain the latest service updates for this support. Please refer to the followinginformation for minimum support levels.zBX AIX V5.3 AIX V6.1PowerHA SystemMirror V6.1 Standard AIX V5.3 TL12 AIX V5.1 TL05Edition RSCT 2.4.13.0 RSCT V3.1.0.3(*)PowerHA SystemMirror V7.1 Standard Not Supported AIX V5.1 TL06Edition RSCT V3.1.0.3(*)Notes: 34
  35. 35. (*) AIX 6.1 TL06 SP3 preferred with RSCT 3.1.0.4 (packaged in CSM PTF 1.7.1.10 installed with AIX 6.1.6.3) is the preferred baseline for zBX Virtual Servers. When setting up disk volumes used for Power HA, care must be taken to define zBX Virtual Server bootable disks such that they are discovered prior to the shared disks used for Power HA resource groups. In most cases this is achieved by defining the bootable disks with LUN IDs lower than the LUN IDs of the shared disks. POWER HA DLPAR control is not supported. The optional zEnterprise management network interface available on AIX servers running in the zBX PS701 blades cannot participate in PowerHA cluster network configuration. This special interface is for Unified Resource Manager purposes only. AIX virtual servers cannot communicate over it, and should be excluded from use in the PowerHA configuration. PowerHA is intended for failover within an ensemble and not for business continuity across ensembles, hence PowerHA Enterprise Edition is not supported in the zBX environment PowerHA 6.1: Since AIX virtual servers on zBX Power blades always use virtualized I/O, the netmon.cf file should be used to maintain proper network availability. Refer to PowerHA 6.1 documentation for setup of netmon.cf. PowerHA 7.1 AIX virtual servers on zBX Power blades cannot be configured with fibre channel adapters, so the PowerHA 7.1 FC heartbreaking feature cannot be used.Question:Is there a limit on the number of virtual servers per blade?Answer:Initially we’ll support 20 virtual servers on the POWER7 blades. Over time, IBM expects that numberwill increase. 35
  36. 36. IBM System x blades for zBXQuestion:What select System x blades will be supported in the zBX?Answer:The zBX will support IBM BladeCenter HX5 7873 blades. The HX5 7873 blade is built on the IBMBladeCenter family of products and designed using the latest IBM X-Architecture® technology withfifth-generation eX5 innovation, with capabilities that help promote greater system uptime andenergy-smart design.Select single-wide two socket HX5 7873 blade configurations have been tested by IBM and are basedon proven technology utilizing Intel® Xeon® Processor Chips. ONLY those HX5 7873 hardwareconfigurations defined by IBM System z will be supported and work in the zBX. The blades areoptimized to achieve maximum performance for both the system and its virtual machines. As amember of the zEnterprise System, the HX5 7873 blade comes under the management of the IBMzEnterprise Unified Resource Manager.Question:Who orders the blades? Is it part of the configuration process by my IBM team?Answer:Similar to the PS701 blade for the zBX today, the System x blade will not be part of the zBXconfiguration. The System x blade with features and software may be obtained through an IBMBusiness Partner or Distributor, an IBM sales representative, or through the web. The followingdocument should be used as a guide for specific ordering information.http://www.ibm.com/common/ssi/cgi-bin/ssialias?infotype=SA&subtype=WH&appname=STGE_ZS_ZS_USEN&htmlfid=ZSL03128USEN&attachment=ZSL03128USEN.PDFQuestion:What would happen if the blade I try to install does not match the supported System x configuration?Answer:The blade would be rejected by Unified Resource Manager.Question:What type of storage will be available for the System x blade?Answer:For IBM open storage information you can use the System Storage Interoperation Center (SSIC) website - http://www.ibm.com/systems/support/storage/ssic/interoperability.wss. For information on supportfrom other industry leaders you can use the IBM Server Proven web site -http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/. Your IBM storage specialist(FTSS – Field Technical Support Specialist) or BP storage specialist can also assist you in finding anopen storage product to support the IBM BladeCenter HX5 7873. 36
  37. 37. Question:What operating system software releases and hypervisor will be supported on the System x blades?Answer:The two Linux operating system configurations that will be supported are Linux RHEL 5.5 and SLES 11SP1. When ordering the operating system for your HX5 7873 blade, you should not have itpreinstalled on the blade. This is primarily due to the fact that the Unified Resource Manager will installan integrated hypervisor (which is KVM based) on the BladeCenter HX5 7873 when it finds the bladeinstalled on the zBX. Second, you may already have a license for the operating system that can beused. Therefore, you may not have a requirement to order the operating system at the time the bladeis ordered.Question:What version of Windows will you be supporting on the System x blade?Answer:NOTE that this information is a statement of direction only. All statements regarding IBMs futuredirection and intent are subject to change or withdrawal without notice, and represent goals andobjectives only. IBM’s intent is to support Microsoft Windows Server 2008 – Datacenter Edition on theHX5 7873 blades installed in the zBX, 64 bit version only.Question:I noticed in your recent announcement there was no reference to your intentions to support Windows inthe zBX, I recall an early statement of directions suggesting 4Q2011. Is that still the plan?Answer:There is no change to our previous statement of direction.Question:Does IBM intend to support virtualization on the System x blades? What about VMware - are thereplans to make this available?Answer:IBM will support virtualization, however, we do not have plans to support VMware or its hypervisor.Question:What applications can run on the System x blade in a zBX?Answer:Applications that are certified for the operating systems supported by the zBX are compatible.Question:What workloads do you expect to execute on the System x blades? I am trying to figure out if myWindows application will be a good candidate.Answer:The IBM zEnterprise provides the ideal foundation and infrastructure required by our customers’increasingly complex workloads. In the future, when we offer Windows support, the aperture ofapplications is widened, and applications that run on Windows will run on the zEnterprise. Best fitworkloads that can take advantage of zEnterprise are workloads and applications that rely on Systemz for data serving and application components, whether it is DB2 for z/OS, IMS™, CICS®, WebSphereor even Oracle. In addition, they are workloads that require the strength of System z but often have 37
  38. 38. application components on Power or Intel that are required to complete the end to end businessprocess.If you have applications running in these two or three tier environments, they may be excellentcandidates for migrating to a zEnterprise. Our recommendation is to work with your IBM or BusinessPartner Sales Representative to run a study – such as our Fit-for-Purpose workshop or BusinessValue Assessment - to help you identify the value zEnterprise can bring your environment. And, sincethere is some time between this SOD and availability, now is an excellent time to run one of thesestudies.Question:Will the System x blades be managed by Systems Director?Answer:No. The zBX blades are managed by the Unified Resource Manager.Question:I am an Independent Software Vendor (ISV) and I see that the zEnterprise will support Linux runningon the BladeCenter Extension (zBX). Does that mean that I no longer have a need to enable myapplications to run on Linux for System z?Answer:No, the need remains. Most applications should still be enabled and deployed on Linux for System z inthe z196 or z114. Putting Linux applications allows the applications to take direct advantage of the zarchitecture that allows not only close proximity between applications and database, but it alsoincludes the following: Using the IBM zEnterprise – the server family that can offer extreme scalability and performance for transaction processing and data serving The only hardware with L4 Cache to help with high throughput Internal private communications within the box at up to 6GB/s Hardware encryption capabilities I/O and Network off-load built into the hardware that allows high through puts even when virtualized and running CPU greater than 90% utilization. And with zBX the ability to leverage software/ hardware combinations to further enhance a complete solution Leveraging the internal architecture and new capabilities will allow most ISV code to run in a manner giving customers increased value in the code they are running.While deploying an application on a zBX provides centralized management through the UnifiedResource Manager, applications running on the z196 or z114 also receive the well-known “qualities ofservice” that remains System z’s competitive advantage. Although different applications have differentneeds, some of these qualities are reliability, performance, availability, accounting, scalability, I/Obandwidth, staff productivity, and so on. Applications desiring System z levels of these attributesshould choose deployment on Linux on System z. As well, the consolidation capabilities on the z196and z114 allow for a cost attractive large scale data center simplification and optimization. Thoseapplications that have been a fit on a blade in the past, and dont require the qualities of service ofSystem z, will still remain a fit on the blades in a zBX environment. 38
  39. 39. Remember that in general, a mixture of applications running on Linux for System z will overall performbetter as System z typically provides higher utilization levels vs. a number of blades. Although yourmileage may vary, distributed servers often run at average utilization levels in the range of 5 to 20%.On an IFL, one can achieve nearly 100% utilization nearly 100% of the time. Both the z196 and thenew z114 have many performance enhancements that allow direct native Linux on System zapplications to perform better than on earlier System z processors as well.Finally, many ISVs already have their applications directly executing on Linux for System z and willwant to continue to enhance and add to their portfolio of those applications native. 39
