While users have a long-term interest in tapping into public cloud services, many organizations are still focusing primarily on the deployment of private clouds, in which server, storage, and network resources are consolidated into a single pool that workloads can draw upon as needed. Eventually, as private clouds mature, they could evolve into “hybrid” clouds that have the ability to send some workloads to public clouds where appropriate, ideally with the same frameworks and controls used to allocate on-premise resources. In the meantime, a key benefit of private clouds is their ability to enable some degree of self-service, while also accounting more precisely for the resources consumed by users and workloads. By eliminating much of the administrative overhead required to deploy services, and more precisely allocating the resources needed to support these services, private clouds can introduce significant cost savings and improve an organization’s responsiveness to changing business conditions.This document is copyrighted  by Ideas International, Inc.

  • 2. SEEDING CLOUDS ON POWER SYSTEMS WITH IBM SMARTCLOUD™ ENTRY JANUARY 2012 Cloud computing is often associated with virtualization. Most definitions of cloud computingBy eliminating much of the also cover approaches such as software as a service (SaaS) and platform as a service (PaaS), which do not necessarily depend on virtualization. However, for one definition of cloudadministrative overhead computing, infrastructure as a service (IaaS), virtualization provides a powerful means ofrequired to deploy services, adapting existing infrastructure and applications for the cloud. There are a variety of ways to implement private clouds, which usually involve coupling virtualization with managementand more precisely allocating frameworks that are optimized for pooling virtual resources. The implementation of privatethe resources needed to clouds also usually requires tools for enabling self-service provisioning, whereby users select the services they need, after which the virtualized back-end resources needed to support thesupport these services, services are automatically assembled.private clouds can introducesignificant cost savings and Virtualizing Critical Workloadsimprove an organization’s Even before the emergence of cloud computing, virtualization was having a major impact across the IT industry. In a variety of real-world environments, virtualization has alreadyresponsiveness to changing proven its ability to deliver some key business benefits, including:business conditions. » Consolidation and improved resource utilization » Simplified resource provisioning » Simplified high availability (HA) and disaster recovery (DR) » Legacy application support » Improved test and development processes Consolidation is perhaps the most widely applied use case for virtualization. Consolidation enables administrators to reduce the number of physical machines that they have to acquire and manage. The improved resource utilization reduces the server and storage hardware footprint, which can lower acquisition costs and also reduce some operational costs related to maintenance, cooling, and power consumption. Compared to physical servers, virtualization also dramatically reduces the time required to provision new systems. While the end-to-end time required to bring up a new physical server can span weeks or months from planning to actual deployment, virtual machines can be launched in minutes or seconds. Virtualization also makes it easier to reconfigure systems in response to fluctuating workloads. Live migration of virtual machines between servers provides flexibility for assigning computing resources to workloads. This capability enables computing resources to be treated collectively as virtual infrastructure that can be reallocated to different workloads on demand without having to reconfigure physical resources. While much of the industry’s recent interest in virtualization has focused on industry-standard x86 servers, the use of virtualization in fact goes far beyond x86 systems. After being a core feature of mainframe and UNIX servers for decades, virtualization technology is now available on all of the major server platforms in use today. Some non-X86 platforms can offer significant added value for users who want to virtualize enterprise computing workloads (meaning workloads that may involve multisite, multidepartmental operations, in which disruption can significantly affect revenue or key business functions). In these environments, users may need to virtualize very large workloads, or very fast-growing workloads, and they cannot afford to have hardware or software act as limiting factors to business operations. Cloud computing further increases the need for robust virtualization platforms, as the virtualization layer effectively becomes the central point of control for all computing resources. Therefore, platforms that need to support enterprise cloud computing deployments require a variety of optimizations to maximize the scalability and reliability of virtualized workloads.2 WHITE PAPER |  2012 IDEAS INTERNATIONAL, INC.
  • 3. JANUARY 2012 SEEDING CLOUDS ON POWER SYSTEMS WITH IBM SMARTCLOUD™ ENTRY Scalable VirtualizationOne of the main reasons Performance and scalability are two of the greatest priorities for administrators when deploying enterprise workloads. In an enterprise environment, users need to have confidence that theirfor using virtualization to infrastructure will be able to deliver acceptable service levels even under heavy or rapidlyimplement clouds is that changing load conditions. The success of any cloud computing platform that depends onit can be used to make virtualization will thus hinge on its ability to deliver whatever resources are needed by a workload, whenever those resources are needed. The scalability of a virtualization platform thatsure workloads always has to support clouds can be measured in two ways:have sufficient resources » Host scalability. The scalability of the host environment in a virtualization platform determines how many virtual machines can be hosted on a single server, and thusto provide the necessary determines the scale of consolidation that can be achieved, and the economies of scale thatservice levels, even under can be achieved in a cloud environment. There are three factors that determine the host scalability of a hypervisor:variable demand. – The largest amount of physical memory that is usable by the hypervisor – The largest symmetric multiprocessing (SMP) configuration of server hardware that the hypervisor can exploit – The maximum number of virtual machines that can be deployed on a single server » Guest scalability. The scalability of a guest environment determines which classes of workloads are suitable for virtualization on the platform. Guest environment scalability primarily depends on two limits: – The largest amount of memory that is accessible by guest operating systems running in the virtual machine – The ability for the virtual machine to provide multiple virtual processors that can be used simultaneously in virtual SMP configurations Reliable Virtualization The reliability of infrastructure also remains one of the greatest concerns in enterprise environments. Cloud computing inherently involves some degree of centralization, which is a key enabler for achieving the economies of scale that deliver much of the cloud’s value. Using virtualization for consolidation enables fewer physical servers to be deployed, which reduces the footprint for potential hardware failures. However, consolidation also increases the importance of avoiding downtime in individual servers, both unplanned and planned. Therefore, virtualization platforms that have to support cloud computing need to address reliability at several levels, including: » Fault resiliency. For virtualization platforms to handle the most critical workloads, they require the ability to adapt to certain failures that can occur in electronic components such as memory, CPUs, and I/O interfaces. Although server hardware has gotten more reliable over time, restarting large numbers of virtual machines on backup hardware in the wake of a server failure can still be time consuming and disruptive. Therefore, host failure should be avoided to the greatest extent possible. » HA clustering. Virtualization simplifies recovery from failures. An entire virtualized workload can easily be relaunched simply by restarting the virtual machine on which it is hosted. Further, when coupled with HA clustering functions, virtualization can be used to automatically restart workloads on a backup host in the wake of a primary host failure – dramatically simplifying the implementation of DR procedures. » Live migration. The ability to migrate virtual machines from one host to another with little or no interruption to processing is a key benefit of virtualization that helps to reduce planned downtime. Live migration functions of a virtualization platform should allow workloads to be temporarily moved so that routine hardware maintenance can be performed on the hosts with minimal disruption.WHITE PAPER |  2012 IDEAS INTERNATIONAL, INC. 3
  • 4. SEEDING CLOUDS ON POWER SYSTEMS WITH IBM SMARTCLOUD™ ENTRY JANUARY 2012 The scalability of a virtualization host platform also plays an important role in maintainingThe primary challenge for availability of virtualized workloads. One of the main reasons for using virtualization to implement clouds is that it can be used to make sure workloads always have sufficientmost users is to stage the resources to provide the necessary service levels, even under variable demand. To maximizegradual adoption of private consolidation ratios and make optimal use of real resources such as space, power, and cooling, “scale up” configurations of SMP server hardware should be exploited to achieve as muchclouds in a way that allows performance as possible within a single server footprint. Virtualization platforms should alsothe benefits of cloud comput- have the ability to dynamically and quickly reallocate resources to virtualized environments, including adding and removing CPU, memory, and I/O resources in response to administratoring to be accrued as quickly command or workload management software.as possible. The platformthat customers select as Virtual Infrastructurethey begin the journey to the As the use of virtualization becomes a part of standard operating procedure across the industry, users are developing strategies to drive virtualization technology more directly into ITcloud becomes instrumental infrastructure, extending the scope of its functionality from single servers to multiple systemsin meeting this challenge. throughout a datacenter or organization. Using cloud computing for IaaS usually depends on the deployment of such virtual infrastructure, in which multiple virtual machine hosts can be treated as a single, flexible pool of resources that are allocated dynamically in response to changing workload conditions or downtime events. Virtual infrastructure is enabled in part by the ability to perform online migration of virtualized workloads, whereby the workloads are migrated from one host to another with minimal disruption. With virtual infrastructure, the virtualization platform becomes the primary gateway between workloads and external storage and networks. The virtualization platform thus carries a fundamental responsibility for moving data between virtualized applications and the real world. Therefore, the storage and networking capabilities of a virtualization platform become especially critical components in organizations that are virtualizing applications with heavy I/O demands. Virtualized storage and networking are also key concerns for organizations that are virtualizing entire datacenters or computing infrastructures, requiring multiple virtual machine hosts to share data and processing over the network. Finally, once virtual infrastructure is in place, users require tools to manage virtual resources and control how they are assigned to workloads. Because virtual machines inherently decouple workloads from the details about the hardware on which they are deployed, administrators gain significant flexibility in matching applications with their required computing resources. However, the addition of a virtualization layer within systems potentially introduces uncertainty – and complexity – because the relationship between workloads and computing resources inherently becomes indirect. Management tools should thus provide visibility over both the physical and virtual layers of infrastructure, preferably from the same interface. If possible, administrators should also have consistent visibility and control over other layers of infrastructure, such as storage and networks. The closer the relationship between the management of all these components, the easier it will be for administrators to achieve the operational benefits that cloud computing promises. Making the Leap from Virtualization to Cloud Computing As described above, the deployment of private clouds has some basic technical prerequisites, including robust virtualization platforms with effective virtualization management tools. However, in order to successfully deploy clouds, IT organizations must also adopt certain operational practices for managing virtualized systems. These include: » Simplifying IT services, and standardizing on a select set of virtualized images to implement these services » Implementing robust processes for managing the lifecycle of these virtualized images4 WHITE PAPER |  2012 IDEAS INTERNATIONAL, INC.

The primary challenge for most users is to stage the gradualcomputing. adoption of private clouds in a way that allows the benefits of cloud computing to be accrued as quickly as possible. The platform that customers select as they begin the journey to the cloud becomes instrumental in meeting this challenge. Virtualizing Critical Workloads with IBM PowerVM IBM offers three strategic server platforms, each of which can play a role in the deployment of cloud computing. One of these platforms, IBM Power Systems, has recently seen a significant increase in interest as a foundation for hosting clouds. Power Systems include a complete set of virtualization capabilities that are optimized for the POWER® processor, called PowerVM. When coupled with the necessary software functions to implement clouds, PowerVM provides an optimal platform on which to pool computing resources that workloads can draw upon as needed, while allowing users to activate services on a self-service basis. There are several reasons why users may be considering PowerVM as a platform on which to host private clouds. First, Power Systems rank among the most scalable server platforms in the industry. The POWER7® processor used in Power Systems has outstanding per-core performance, and servers can scale up to 1,024 virtual cores and 8 TB of memory (on the largest system, the Power 795). Power Systems currently hold four of the top five nonclustered (that is, SMP based) rankings on the TPC Benchmark™ C (TPC-C),1 which is one of the most demanding validations of SMP server architectures in the industry, putting maximum stress on processors, memory, and I/O. Thus, PowerVM has proven its capability as an extraordinarily scalable platform on which computing resources can be pooled with confidence. Security and compliance are vital to many businesses, especially now that they must adhere to regulatory requirements designed to safeguard personal data and company information from attacks and breaches. Ensuring that cloud deployments are compliant with common industry security standards and maintaining system security can be a challenging, labor-intensive activity especially with today’s virtualized IT infrastructures. IBM® Power Security and Compliance (PowerSC™) provides a security and compliance solution optimized for virtualized cloud environments on Power Systems servers, running PowerVM and AIX®. Further, Power Systems offer very high levels of availability. The high degree of integration in the POWER7 processor and its advanced multichip packaging enable a number of mainframe- class reliability functions. Power Systems have a variety of self-management and self-healing capabilities, such as First Failure Data Capture and Clustering Data Aggregation Tool, Chipkill with bit-steering/redundant memory, deallocation of PCI bus and L2/L3 cache lines, and 1 As of January 2012, three of the top-five nonclustered TPC-C results are on IBM Power Systems, and one is a POWER7-based system from Bull, which is tied for first place.WHITE PAPER |  2012 IDEAS INTERNATIONAL, INC. 5

(Power Systems support three operating systems: AIX, IBM i, and Linux, all of which can be virtualized with PowerVM.) The superior scalability of Power SystemsSystems Director VMControl applies directly to the scalability of PowerVM itself. PowerVM can support up to 256 virtualEnterprise Edition. processor cores (representing 1,024 threads) in a partition, allowing very large workloads to be virtualized just as if they ran on physical hardware. Operating systems that run in PowerVM, including AIX and IBM i, have the ability to add and remove resources such as CPU, memory, and I/O without being rebooted. This capability allows the boundaries between partitions to be adjusted dynamically in response to changing workloads without interrupting operations. PowerVM’s Virtual I/O Server (VIOS) allows a single Micro-Partition to provide I/O connectivity for the other Micro-Partitions in a server and eliminates the need for I/O devices (storage and network adapters) in each partition, reducing cost and complexity. VIOS partitions can be configured in redundant pairs, so that each can take over the operations of the other in the event of failure. Some of the other important virtualization functions provided by PowerVM include the following: » POWER Hypervisor™ can automatically adjust processor and memory resources in a Micro- Partition based on current utilization and user-defined priorities (the size of a Micro-Partition can be adjusted in increments of 1/100 of a processor). » Active Memory™ Sharing improves utilization of system memory by allowing physical memory in a machine to be assigned into a shared pool, and allocated to partitions on the fly. Active Memory Sharing also includes support for memory overcommitment, so that if all partitions in the physical server request more virtual memory than is physically available, the partitions can use the VIOS partition as a paging device. » Shared Dedicated Capacity and Multiple Shared Processor Pools can be used to dynamically and automatically allocate resources to Micro-Partitions based on business-driven policies. » Live Partition Mobility allows a partition to migrate from one physical host to another without interrupting the processing of its workloads. This function is essential for reducing planned downtime, since it allows servers to be taken offline for maintenance while allowing virtualized workloads to continue providing service. It also increases flexibility for administrators by allowing them to match virtualized workloads with the resources they need, regardless of which physical server those resources happen to be available on. Virtualization Management on IBM Power Systems All IBM server platforms can be managed through the same interface using a tool called IBM Systems Director, which is optimized to measure and control low-level functions in IBM’s servers, including power draw. Systems Director can be used to manage environments with a mix of physical and virtual systems from a single, consistent interface. To help manage virtualized environments, Systems Director provides a set of plug-ins, called Systems Director6 WHITE PAPER |  2012 IDEAS INTERNATIONAL, INC.

Workloads can tap into these pools on demand in response to changing conditions. Another extension for IBM Systems Director, the Storage Management plug-in, can be used to coordinate virtual machine provisioning and live migration for server, storage, and network resources. The plug-in can be used to perform lifecycle management of storage systems, including discovery, health and status monitoring, configuration, updates, and management of storage virtualization functions. The combination of PowerVM and IBM Systems Director enables the virtualization of enterprise workloads that have the highest demands for scalability and reliability, and it can serve as a solid foundation to adapt such workloads for cloud computing. However, some additional tools are needed to let users treat a virtualization platform as a cloud. These tools should give users the ability to rapidly deploy their own services with minimal knowledge about the underlying computing infrastructure. Seeding Clouds on IBM Power Systems As interest in cloud computing started to gain traction across the industry, IBM responded by assembling a range of cloud deployment solutions based on its systems, software, and services. These solutions are tailored to meet the requirements of different classes of users, depending on their progress toward standardization of IT services, their need for integration, and their interest in retaining control of infrastructure. IBM’s overall strategy for cloud computing is based on a common architecture called IBM SmartCloud, which targets the following four classes of cloud usage: » Business process as a service (BPaaS) » Software as a service (SaaS) » Platform as a service (PaaS) » Infrastructure as a service (IaaS) To meet customer needs for the latter two classes of cloud deployment, PaaS and IaaS, IBM has introduced two initiatives: » IBM SmartCloud Foundation is a set of technologies for deploying private and hybrid clouds for IaaS. These technologies are designed to let customers easily build and rapidly deploy private cloud environments based on integrated solutions from IBM, as well as IBM management tools. » IBM SmartCloud Services is IBM’s approach to PaaS, whereby IBM provides a service delivery platform for rapidly deploying applications with maximum scalability, security, and portability. The initiative includes an array of offerings that allow customers to host a variety of specific application services on platforms managed by IBM and its partner ecosystem.WHITE PAPER |  2012 IDEAS INTERNATIONAL, INC. 7

Metering and billing IBM Systems IBM Systems Director functions can be used for tracking consumption of shared virtual computing resources and, Director VMControl where appropriate, allocating costs to users on a chargeback basis. In sufficiently advanced clouds, the applications themselves may also be optimized for cloud deployment. PowerVM IBM recognizes that many users are not ready to skip immediately to the deployment of OS OS OS advanced private clouds, despite their potential benefits. More likely, depending on their culture and priorities, organizations will begin to adopt cloud computing with simpler initiatives, and IBM Power Systems progress gradually to more sophisticated cloud deployments. Correspondingly, IBM has started to refine its cloud offerings in order to give customers a choice of entry points. Customer-specific integration At the high end, IBM SmartCloud Foundation has offerings that range from high-touch service engagements, in which IBM will take on the entire task of bringing cloud computing to a customer based on their specific needs, to highly integrated solutions that customers can install themselves, such as IBM Service Delivery Manager. These solutions generally provide complete capabilities for service orchestration and integration, automated IT service deployment, end-to- end lifecycle management, and metering and chargeback.2 However, the high-end solutions in IBM SmartCloud Foundation can incur considerable up-front investments to plan and deploy, and they may also require users to take on some complexity in order to achieve the complete benefits of clouds. Some customers may seek a simpler approach that allows them to deploy clouds quickly, and without major changes to operations. For these users, IBM has introduced an offering called IBM SmartCloud Entry, a scaled-down software package that enables clouds to be deployed rapidly and with minimal disruption to existing infrastructure and administrative processes. IBM SmartCloud Entry is a solution that enables users to rapidly deploy private clouds based on their existing Power Systems infrastructure. SmartCloud Entry allows administrators to deploy a self-service portal on top of PowerVM and IBM Systems Director VMControl Enterprise Edition (see Figure 1, upper left). With a flexible, modular design and a small footprint, SmartCloud Entry offers the following features: » An administrative interface to create and replicate cloud services, as well as manage the deployment of these services and monitor their activity. 2 See Private Clouds Float with IBM Systems and Software, Ideas International, February 2011 at: http://public.dhe.ibm.com/common/ssi/ecm/en/xbl03006usen/XBL03006USEN.PDF.8 WHITE PAPER |  2012 IDEAS INTERNATIONAL, INC.

The integration of SmartCloud Entry with IBM Systems Director VMControl Enterprise Edition allows servers and storage to be assigned to pools of virtualized resources that virtualized workloads can tap into on demand. As a result, cloud administrators can quickly scale up virtualized infrastructure by simply adding servers, blades, or storage devices to these pools. SmartCloud Entry gives users a quick and easy way to set up private clouds, while fully capitalizing on the reliability and scalability benefits of the Power Systems platform. As these users become more comfortable with cloud computing, and seek to gain additional cost and responsiveness benefits from increased integration, they can progress from SmartCloud Entry to IBM’s more advanced cloud offerings, such as IBM Service Delivery Manager. In the meantime, SmartCloud Entry offers a relatively low-risk method of introducing the key operational processes required for cloud computing (standardizing IT services, building libraries of these services, and implementing procedures for users to provision these services on their own). The IDEAS Bottom Line Many organizations are genuinely excited about the potential for private clouds, anticipating greater responsiveness for end users and reduced costs for administrators. These organizations may have already achieved considerable success in their adoption of virtualization, and they would now like to build on that success with extensions for enabling private clouds. However, they are also concerned with minimizing the risk of disruption as they make the transition to cloud computing, which by definition introduces new management processes that fundamentally redefine how resources are assigned to workloads. One way to reduce the risk of deploying private clouds is to make the simplest possible extensions to existing virtualization platforms for adding key cloud capabilities. These extensions should include tools for creating service catalogs, and self-service portals that allow users to assume some self-service provisioning. The tools can offload some management tasks from administrators, and thus help to reduce management costs. Users may achieve a relatively quick return on investment from private clouds by deploying them on server platforms with characteristics that already align well with the core requirements of cloud computing. These characteristics include sufficient scalability to support massive levels of consolidation, and the resiliency to maintain uptime for services in the event of hardware or software failures. IBM SmartCloud Entry provides a set of building blocks that will allow users to deploy private clouds quickly and easily on the proven virtualization capabilities of IBM Power Systems.
