  • {DESCRIPTION} This screen contains a group of IBM System Storage units. The storage units are (from top to bottom): DS3500, DS5020, DS5100, and DS5300 . {TRANSCRIPT} Welcome to IBM Systems x Storage Overview. This topic introduces the entry-level and mid-range disk storage products and offerings. This is Topic 5 of the System x Technical Principles XTW01 Course.
  • {DESCRIPTION} This screen lists the topic objectives. {TRANSCRIPT} Upon the conclusion of this module, you should be able to : Identify IBM Disk Storage System product line Identify the storage positioning of each of the products Discuss the features of the IBM Entry-level Disk Storage System Discuss the features of the IBM Mid -range Disk Storage System Summarize key attributes of each storage family products
  • {DESCRIPTION} This screen lists the topic agenda. {TRANSCRIPT} In this topic will define the IBM Entry to Midrange System Storage Disk Systems DS3000 Series and DS5000 Series products and its disk attachment methods that are designed to provide compelling storage solutions with superior value for all levels of business. We will discuss the following technologies: Serial-Attached SCSI (SAS), Fibre Channel (FC), and Internet SCSI (iSCSI), and provide an overview of its management software. We will begin with an overview of the IBM System Storage Disk Systems portfolio.
  • {DESCRIPTION} This screen displays four rectangle squares that lists Information Infrastructure key phases. {TRANSCRIPT} IBM offers a wide range of products and services that can help clients: Improve service, Reduce costs and Manage risk. That is why Information Infrastructure (being one of the six pillars of Dynamic Infrastructure) is often seen as the foundation of a Dynamic Infrastructure. Information Infrastructure is all about Storage Products. It guides us in the way we build or acquire our products and the way we transform them into solutions for our client. The definition of Information Infrastructure is simple: To reach a resilient infrastructure for securely storing information and mitigating information risks. In our way to do so, Information Infrastructure has four basic capabilities (as shown here) we want to be resident in our products: they have to be able to support: Information security Information compliancy Information retention Information availability
  • {DESCRIPTION} This screen displays images of the IBM Entry-Level DS3000 and Mid-Ranger Storage DS5000 positioning that are identified in 4 tiers from left to right as tier 1: DS3200, DS3300, and DS3400, tier 2: DS3500, tier 3: DS5020 and DS3950, tier 4: DS5100 and DS5300. {TRANSCRIPT} And as you can see, IBM entry to midrange product portfolio are well established performance-leading storage solutions designed to meet client’s needs at whatever size their organization might be. Starting from the left, DS3000 series which is cost-effectively priced to fit the limited budgets of entry and small to medium organizations offering a wide range of host interface options include SAS, iSCSI and fibre channel. It allows clients the flexibly to meet their organization’s unique infrastructure requirements whether that is direct connect with SAS, low cost networking with iSCSI, or fibre channel for your most demanding environments. It also offers a very intuitive storage management that is great for entry-level users while still offering a great amount of control. The DS3500 is an entry-level storage solution that offers midrange performance and enhanced replication capabilities, as well as scalability. The DS3500 supports concurrent SAS and iSCSI or SAS and FC connectivity. With performance that is ideally-suited for mixed workload, virtualization and consolidation environments, the DS3500 can meet the requirements of a range of organizations. And while intuitive, the DS Storage Management features of the DS3500 bring extra control and functionality to their storage system configuration. As we scale up to larger organizations, the DS5000 series systems midrange product portfolio continues to get stronger. The DS5020 Express and the DS3950 Express (which is not supported in NA) are the follow-on products for the highly successful DS4700. The DS5100, released in 2008, is the follow-on product for the DS4800. (Be aware that the DS5100 without the High Performance Feature may not out perform the DS4800). The DS5020 is a FC-based storage system ideally suited for midrange and larger organizations. It offers exceptional IOPs performance that is great for transactional applications such as database and Exchange. Offering FC and iSCSI connectivity and scalability, DS5020 is ideal for tiered SAN environments supporting both high performance and secondary SAN applications. The DS3950 is a version of the DS5020 that is offered in the European and some Asian Pacific geographies. It has most of the same capabilities as the DS5020 with the major difference being the number of available host fiber channels attachments it can have, and supported drive types. Pushing midrange storage further into the data center is the flagship DS5300 and the DS5100. As with the DS5020, the DS5100 and DS5300 offer FC and iSCSI host connectivity for mixed SAN support. The DS5000 series supports solid state drives, FC and SATA drives as well as full disk encryption drives (FC only) to easily secure data-at-rest with no impact on performance. The DS5100 and DS5300 can also scale to an impressive 448 drives with EXP5000 & EXP5060 using FC & SATA drives and 480 drives only the EXP5060 and SATA drives . The DS5100 and DS5300 are not only a good fit for the data center, but also high performance computing, with its high performance and the ability to scale to great capacities.  
  • {DESCRIPTION} This screen lists the topic agenda. {TRANSCRIPT} In this section we will review the DS3000 and DS3500 Entry-level storage system interface options, specifications, functions, and supported platforms of the DS3000 Entry-Level family of disk storage products.
  • {DESCRIPTION} This screen contains a larger yellow arrows that extends from the lid-left slide of the screen to the top-right corner, It also displays images of the entry-level storage units from top to bottom: DS3512/DS3524 models, DS3400, DS3300 and the DS32000 System Storage. {TRANSCRIPT} The IBM System Storage DS3000 series, IBM’s Entry-level storage systems, which are specifically designed to address the needs of the small-and medium-sized businesses, and to deliver advanced functionality at a breakthrough price. The DS3000 series provides an exceptional solution for workgroup storage applications such as email, file, print and Web servers, as well as collaborative databases and remote boot for diskless servers. The DS3000 series connects to the EXP3000 Expansion unit.

DS3500 provides increased consolidation and efficiency with multi-protocol host support featuring 6 gigabyte SAS technology delivering improved performance, concurrent host connectivity with iSCSI, SAS (now 6Gbps SAS instead of 3Gbps) and Fibre Channel (now 8Gbps instead of 4Gbps), increased scalability and more features an affordable storage system for the entry-level to the midrange. Supporting the legacy premium features, the DS3500 also adds remote mirroring across FC host ports. Today we are happy to introduce the much anticipated IBM System Storage DS3500, IBM’s new flagship entry level storage system. A good brief description of the DS3500, similar to a quick commercial about the storage system, or if someone asked you to quickly tell them about it, a good description would be that it is our next generation entry-level storage system with 6 gigabyte SAS technology delivering improved performance, concurrent host connectivity with iSCSI and SAS or Fibre Channel and SAS, increased scalability and more features. The DS3500 can only be connected to an EXP3512 and/or DS3524 Expansion units. The EXP3000 Expansion unit is not supported. And I will let you review the benefits listed below which we will cover in more detail in throughout the remainder of this presentation.
  • {DESCRIPTION} This screen displays an image of the DS3000 2U System Storage with drive slots numbered 1 through 12. {TRANSCRIPT} With the exception of the product label, the front of the DS3200, DS3300 and DS3400 are basically the same. They are all in-cased in a 2U enclosure that features: Front Diagnostic LED Panel Up to 12 HDDs drive bays with internal SAS HDD connectors and an online capacity expansion up to 48 drives utilizing three EXP3000s - supporting a mixture of SAS and SATA HHD drives. Each drive slot contains an Activity LED and a Bi-color Status LED. All the disk storage drives are accessible from the front of the unit. The disk drives are numbered 1 through 12, from left to right. Dual-active RAID controllers with mirrored, battery-backed data cache: 512 MB per controller standard, upgradable to 1 GB per controller Redundant, hot-swappable controllers, drives, ESMs, power supplies / fans Unlimited global hot spare drives with automated failover/failback DACstore - stores configuration metadata on each drive Online administration, expansion, configuration, RAID level migration, firmware upgrades ( Exception to this is upgrading the DS3000 from Storage Manager v9 to v10.35+ which is an offline upgrade) Hardware XOR engines for high-speed parity calculations The DS3000 Series a DC powered model that is especially suited for telco industry environments. The IBM DS3000 System Storage Model 42T, a NEBS-3 and ETSI compliant disk system and the IBM System Storage EXP3000 Model 02T storage expansion unit are both designed to be powered from a -48V dc telco industry-standard power supply. Intuitive DS3000 Storage Manager software Support for up to 32 Storage Partitions, and Enables optional copy and disaster recovery (DR) features such as IBM FlashCopy and Volume Copy that can be enabled when an application necessitates it.
  • {DESCRIPTION} This screen displays image of the DS3000 controller with power and fan unit, and contains 3-D images of the DS35000 storage unit. {TRANSCRIPT} Located in the rear of each DS3000 expansion units you will notice standard components that are also common among each controller (number of components and the placement of the components varies depending on the model). As you can see when you compare the DS3000 controllers, each controller has a standard one 6-Gbps SAS connection port for connecting to drive expansion unit, one 1-Gb RJ-45 Ethernet ports for management purposes, and one or two PS/2 serial interfaces that is available for service personnel. Only on the DS3200 controller will you find the 6 Gbps SAS host port for connecting to hosts, this feature is disabled on the DS3300 and DS3400 models. Located at the bottom on each controller module is a 515-watt redundant hot swappable power supplies with, dual-active integrated fans, and a battery charger. In addition each component has its own LEDs indicators. What you don’t see in both diagrams is the placement of the host interface options. This feature is what basically separates and distinguishes the controllers from one another. You will also find some of these components standard among the EXP3000 Expansion enclosure. The RAID controllers and Environmental Services Modules (ESMs) is what differentiates the two.
  • {DESCRIPTION} This screen displays images of the DS3500 System Storage units: DS3524 (with 12 drive bays) and DS3512 (with 24 drive bays). {TRANSCRIPT} When you compare the DS3500 models together, the first thing you notice is the difference in the drive casing. The DS3512 front view features are exactly the same as the DS3000 with 12 3.5” drive bays, however the DS3524 drive casing supports up to 24 2.5” drives. Both expansion units supports up to 96 drives utilizing three EXP3512 and/or EXP3524 - supporting a mixture of high performance SAS, Nearline-SAS and full disk encryption or SED SAS drives. The disk drives are numbered for the DS3512, 1 through 12, from left to right, and for the DS3524 1 through 24 straight across the unit from left to right. In addition, DS3500 share many of the features of the DS3000 with the addition of Dual-active RAID controllers with 1GB cache per controller with 2 GB upgrade (battery-backed). The battery is used only long enough to flush cache to the internal flash drive, it is not used to hold data in cache like a DS3000. Hardware XOR for RAID 5 and P+Q for RAID 6 performance Intuitive DS Storage Manager software which is the same as the DS5000 storage Manager Support for up to 64 Storage Partitions, and Support for FlashCopy, VolumeCopy and Remote Mirroring (Restricted to 8 LUN for Remote Mirror)
  • {DESCRIPTION} This screen displays image of the DS35000 storage unit controller with out a power and fan unit, and 3-D drawings of the DS3500 storage unit. {TRANSCRIPT} With the DS3500 you will also find that the rear of each expansion units contains standard components that common among each controller. The only variation is the drive form factors (3.5” x12 or 2.5” x24) and the optional host interfaces. Regardless of the host interface, each controller has two 1-Gb RJ-45 Ethernet ports for management purposes, and one or two PS/2 serial interfaces that is available for service personnel, two external SAS connections (shown in the middle of the unit) for connecting to hosts, and a additional SAS connection (far right of the controller) for connecting to drive expansion units. Located at the bottom on each controller module (which is not shown in this image the DS3500 controller) is a 585W AC Power redundant hot swappable power supplies with dual-active fans, and a battery charger. The serial connection, LEDs, and 7-segment display are similar to other mid-range units, such as the DS5020. You will also find that the package for all DS3500 and EXP3512/EXP3524 units are the same, you will also find some of these components standard among the EXP3500 Expansion enclosures. Only the drive form factor, RAID controllers and Environmental Services Modules (ESMs) is what separates and distinguishes them. Note that you cannot connect a EXP3000 (SAS I) to a DS3500 (SAS II), same holds true for the drives DS3000 drives will not work on DS3500. We will dive more into the distinguished features of the DS3000 and DS3500 as we proceed through this topic.

We have already identified the rear common characteristics of the DS3000 series, so now lets focus on the what makes the DS3200 unique. The DS3200 controller contains one external 3-Gbps SAS host port (located in the far left of the controller) for connecting to hosts, and with the option to add a SAS daughter card provides two additional SAS ports. Located to the far right is another 3-Gbps SAS port for drive expansion connectivity.
  • {DESCRIPTION} This screen displays an architecture layout of the DS3200 single controller with three port connections. {TRANSCRIPT} Now lets take a look at this diagram that highlights the DS3200 controller internal features. First is the three 3-Gbps SAS host interface connections which allows point-to-point increased data throughput, and contains a PCI-X bus that supports storage system performance between the ASIC and external interfaces. The core processor features an Intel 667MHz Xscale processor with embedded XOR engines, which performs both the XOR and parity calculations. The storage unit also possess a 512 MB of memory per controller with 128 MB for processor memory and 384 MB for dedicated data cache, and an optional 1 GB of memory can be added per controller with 128 MB for processor memory and 896 MB for dedicated data cache. At the very bottom is a 24-port expander that provides scalability of the DS3200.
  • {DESCRIPTION} This screen provides a top right-aligned image of the DS3300 storage unit. {TRANSCRIPT} The IBM System Storage DS3300 is designed to meet the availability and consolidation needs for a wide range of users – from the entry-level SMB to an enterprise’s remote site or departments. The DS3300 provides organizations an affordable, reliable and scalable storage solution that takes advantage of their current Internet Protocol (IP) infrastructure equipment and in-house expertise. The iSCSI connectivity is well-suited for low-cost storage networks, leveraging low-cost IP network equipment. Utilizing consolidation and single management provides increased efficiencies within the IT infrastructure. It is an external solution for System x and BladeCenter servers. IBM DS3300 contains two 1-Gbps iSCSI host ports per controller, and one 3 Gbps Serial Attached SCSI (SAS) port for drive expansion technology Supporting up to twelve 3.5” SAS and/or SATA hard disk drives, it is expandable up to 3 EXP3000s for a total of 48 drives, and supports RAID level 0, 1, 3, 5, 6 and 10.
  • {DESCRIPTION} This screen displays a rear view image of the DS3300 controller and depicts its connection points. {TRANSCRIPT} This diagram illustrates the component placement in the rear of the DS3300 shown here with dual controllers, and to provide an understanding of how the DS3300 works together with the iSCSI host daughter. The DS3300 has one or two controllers with two 1-iSCSI host ports for each controller for connecting to hosts (as shown here). It also contains a 3-Gbps SAS port (in the far right of the controller) for drive expansion connectivity. Notice that a cover is placed over the location of the SAS host port. This is because the port is disable on all DS3300 models.
  • {DESCRIPTION} This screen displays an architecture layout of the DS3300 single controller with a two iSCSI port connections. {TRANSCRIPT} This diagram highlights the internal features which are basically the same as the DS3200 except for the two 1-Gbps iSCSI host interface connections.
  • {DESCRIPTION} This screen provides a top right-aligned image of the DS3400 storage unit. {TRANSCRIPT} The IBM DS3400 System Storage leads the way for consolidating and sharing data within a direct-attach or FC SAN solution, by adding the most advanced front-end 4Gbps FC technology to IBM time-proven designs for enterprise-class RAID storage. With FC host connectivity and SAS back-end technology, the DS3400 Express is designed to improve productivity through data consolidation, availability, performance and scalability. It is also an external solution for System x and BladeCenter servers. IBM DS3400 contains two 4-Gbps FC host ports per controller, and one 3 Gbps Serial Attached SCSI (SAS) port for drive expansion technology Supporting up to 12 hard disk drives in 3.5” SAS and/or SATA drives, it is expandable up to 3 EXP3000s for a total of 48 drives, and provides for RAID 0, 1, 3, 5, 6 and 10 support.
  • {DESCRIPTION} This screen displays a rear view image of the DS3400 controller and depicts its connection points. {TRANSCRIPT} These diagram illustrate the component placement in the rear of the DS3400 shown with dual controllers, and to provide an understanding of how the DS3400 works together with the FC host daughter. The DS3400 can have one or two RAID controllers. Each controller has two 4-Gbps FC ports for host server attachment (as shown here). You need to install an SFP module in each FC connector. The FC ports can operate at 2 or 4 Gbps, depending on the SFP module installed. It also contains a 3-Gbps SAS port (in the far right of the controller) for drive expansion connectivity. Again, SAS host port is disable on all DS3400 models.
  • {DESCRIPTION} This screen displays an architecture layout of the DS3400 single controller with a two FC port connections. {TRANSCRIPT} This diagram highlights the internal features of the DS3400 controller which are basically the same as the DS3200 except for the two 4-Gbps iSCSI host interface connections.
  • {DESCRIPTION} This screen display a DS3000 host cabling topology for a DS3000 Series. In the far left is the DS3200 direct-attach that contains on DS3200 storage unit and three servers, and right below it is the DS3200 SAS SAN attach connection contains one DS3200 storage unit and one BladeCenter chassis. In the center is the DS3300 IP SAN attach configuration that contains one DS3300 storage unit, two FC switches, and four servers. Located in your far right is the DS3400 direct-attach configuration that contains a DS3400 storage unit and two servers. Right below that is the DS3400 FC SAN attach connection contains one DS3400 storage unit, two FC switches, and four servers. {TRANSCRIPT} The diagrams listed illustrates the host cabling for direct-attach, or SAS SAN, IP SAN and FC SAN configurations: The DS3200 hosts are typically direct attached, however, with the SAS Connectivity Module via a BladeCenter chassis - more hosts can be attached. The DS3300 can accept hosts direct attached via cross-over cables or attached through Ethernet switches as an IP-SAN. Up to 32 hosts and 16 maximum host types can be attached. The DS3400 can accept direct attached hosts or hosts that are SAN attached. A SAN switch infrastructure is required for more than two servers.
  • {DESCRIPTION} This screen displays an image of the BladeCenter E chassis with an HS22 blade installed is connected to a DS3200 System Storage Unit and three EXP3000 Expansion units. {TRANSCRIPT} The DS3200 provides low cost storage capacity for IBM BladeCenter and supports a disk-less blade environment for booting and data access. The DS3200 supports attachment up to 14 blade servers within an IBM BladeCenter chassis using the SAS Connectivity Module for data access. The diagram at the bottom illustrates the supported topology for the SAS Connectivity Module and an IBM System Storage DS3200 storage server connected to the BladeCenter E or BladeCenter H chassis. Both booting and data access from the DS3200 is supported on select IBM blade servers that must have a SAS Connectivity Card (CIOv) installed. In this configuration, the RAID functionality is provided by the external DS3200 storage server. So what are the benefits for this type of configuration: Straightforward Supports both boot functionality and data-attach with a single DS3200 Simplifies BladeCenter environment by consolidating OS initialization across multiple servers with simple DS3000 Storage Manager software Scalable Supports up to 14 blade servers When capacity and/or performance requirements change, the DS3200 can scale up to 48 SAS and/or SATA drives Reliable - Reduce the risk of losing access to data No single point of failure (SPOF) with dual active/active controllers and multi-pathing
  • {DESCRIPTION} This screen provides a top right-aligned image of the EXP3000 expansion unit. {TRANSCRIPT} The IBM System Storage EXP3000 is designed to provide maximum storage capacity to the DS3200, DS3300 and DS3400 storage units. This rack mount drive enclosure supports up to 12 hard disk drives in SAS and/or SATA drives. The EXP3000 enclosure comes with one or two Environmental Services Modules (also known as ESM) in the standard configuration. A second ESM must be installed in order to connect the EXP3000 to a dual controller DS3000 system storage unit. The EXP3000 contains two SAS ports on each ESM – one for uplink to a DS3000 controller and one for a downlink to an additional expansion enclosure. You can attach up to three EXP3000 enclosures to a DS3000 System Storage units. There is no direct management facility on the EXP3000. The disks in the EXP3000 must be managed through a ‘parent’ DS3000 controller, using IBM DS Storage Manager.
  • {DESCRIPTION} This screen displays a rear view image of the EXP3000 Expansion Unit with arrows and circles highlighting the ESM module, power/cooling, SAS expansion ports, and diagnostic ports for servicing. {TRANSCRIPT} The main component of an EXP3000 is the Environmental Services Module (ESM) (shown here with two). Each ESM contains two SAS ports labeled In and Out to attach the EXP3000 to the DS3000 subsystem or to the SAS Out port of another EXP3000. The EXP3000 enclosures connect to the drive side SAS port of the DS3000 through a 3-Gbps SAS interface. It also contains one PS/2 serial interfaces that are available for service personnel, and is equipped with two hot-swappable and redundant power supply modules. Each power supply module contains two fans for cooling redundancy
  • {DESCRIPTION} This screen displays graphic images of a DS3400 storage unit and three EXP3000 expansion unit that are cabled together via the IN and OUT ports. {TRANSCRIPT} All DS3000 storage subsystems, regardless of the type of host attachment, use SAS disk drives/SATA Disk Drives and SAS cabling to attach expansion enclosures. The SAS ports on the DS3000 controller and EXP3000 ESM all support SAS cables in 1 or 3 meters with mini-SAS 4x multilane connectors, as shown here. When attaching enclosures, drive loops are configured as redundant pairs utilizing one port from each controller. This helps ensure data access in the event of a path/loop or controller failure. Often referred to as the “Top-Down/Bottom-Up” method. The ESM modules are the same on each side – remember to always cable to the IN (left hand) port and from the OUT (right hand) port. If the SAS cabling on the drive side is incorrect, it will be detected by the DS3000 controller firmware. The DS3000 Storage Manager will alert you about the condition by logging a critical Major Event Log event. In addition, Recovery Guru will point to the miswire condition and advise you of the steps to correct the problem.
  • {DESCRIPTION} This screen provides a top right-aligned image of the DS3512/DS3524 storage units with a SAS cable, FC cable and Ethernet cable. {TRANSCRIPT} As mentioned earlier, IBM DS3500 System Storage is the new flagship entry level storage system with that is designed to increase consolidation and efficiency with multi-protocol host support featuring 6 gigabyte SAS technology delivering improved performance, concurrent host connectivity with iSCSI, SAS and Fibre Channel. With this feature, administrators can add a performance boost to their DS3500 if and when there application and workloads necessitate it. The DS3500 offers three host interface options including SAS, ISCSI or Fibre Channel. Two SAS host ports are standard per controller natively and with an optional daughter card provides additional SAS host ports, 8 Gb Fibre Channel host ports or 1 Gb iSCSI host ports. This supports concurrent iSCSI and SAS or Fibre Channel and SAS connections. In a dual controller configuration with daughter cards, the DS3500 supports up to four or eight SAS host ports, eight FC host ports and four SAS host ports, or eight iSCSI and four SAS host ports. The DS3500 can scale up to 96 intermixed drives. SAS drives are supported including high performance SAS, Nearline SAS which is a superior replacement to SATA, and finally full disk encryption SAS drives which secure data-at-rest. The DS3500 is available with two enclosure options, the EXP3512, and the EXP3524. Both enclosures can be intermixed behind a single DS3500. The IBM DS3500 also introduces the DS Storage Manager to the entry-level space. This software manager combines the simplicity of the DS3000 Storage Manager and the powerfulness of the DS Storage Manager that previously was only available via the DS4000 and DS5000. Remote mirroring is now available with the DS3500 across FC host ports and is compatible with the remote mirroring available on the DS5000.
  • {DESCRIPTION} This screen provides a top and bottom right-aligned 3-D images of the DS3512 and DS3524 storage units. {TRANSCRIPT} When you compare the two models of the DS3500, the only difference between the two is the drive sizes, type and quantities they support. The first model is the DS3512 which houses twelve 3.5-in drives, and the second model, the DS3524 houses twenty-four 2.5-in drives both in a 2U enclosure. Both support dual active controllers, host shared DAS and SAN connections, support field installable daughter cards, as well as 585-watts dual power/cooling units and hot-swappable customer replaceable units.
  • {DESCRIPTION} This screen displays several images of the DS3500 controller with SAS ports, FC ports, and iSCSI ports. {TRANSCRIPT} The DS3500 comes with two SAS host ports standard per controller. If you find that there is a need for additional connectivity, customer installable host daughter cards can be added to achieve additional SAS host port support or concurrent host connectivity with either SAS and FC or SAS and iSCSI. Optional host cards provide increased connectivity and multi-protocol support. However, one important thing to note that in a dual controller configuration, if a daughter card is being added to a controller, the same exact daughter card with the same host connectivity must be added to the second controller. Lets reviews the DS3500 with the installation of all of the daughter card options: First, is the DS3500 (located at the very top) with the addition of the SAS host daughter card. As you can see that this adds an additional two SAS host ports for a total of eight SAS host ports in a dual controller configuration model. The second image displays the DS3500 with the additional FC host daughter card. This will provide four 8 Gbps FC host ports per controller for a total of eight per dual controller model. And you still have the four SAS host ports. And the final image show the DS3500 with the additional iSCSI daughter card. Like the FC card, you get an additional four iSCSI host ports for a total of eight per dual controller and you can continue to have four SAS host ports. After the storage subsystem is installed, you must cable it to hosts, drives, and other external devices, depending on your hardware configuration.
  • {DESCRIPTION} This screen displays several DS3500 host interface topologies. {TRANSCRIPT} The DS3500 builds upon its value of interface flexibility, consolidation and efficiency with multi-protocol host support. With the purchase of a daughter card, the DS3500 can expand its capabilities to supports either two additional SAS host ports or concurrent host connectivity with either four iSCSI host ports or four FC host ports. This illustration presents examples of concurrent host connectivity your organization can take advantage of your secondary distributed storage with iSCSI while simultaneously supporting local high performance production or blade servers with SAS – all with a single storage system. Or another example would be the SAS ports again supporting local production or blade servers and adding a fibre channel host card to provide consolidation of tier 1 primary servers within your organization. With this capability, you are not locked into a single host interface choice. Now, you can add additional host interface support if and when needed on the storage system. For a SAS host connection: Use a 1M or 3M (1-meter or 3-meter) SAS cable with a mini-SAS 4x multilane SAS connector on each end to connect the controller host port to a SAS host HB For an iSCSI host connection: Use a Category 5e or Category 6 Ethernet cable from the RAID controller host port to a gigabit Ethernet switch, and then connect an Ethernet cable from the switch to the host iSCSI initiator port. For a FC host port connection: Use a small-form-factor pluggable (SFP) module to connect a host port to the host by inserting the SFP module into the port, and then a fiber optic cable is inserted into the SFP module. The other end of the fiber optic cable connects to an optical interface connector in a Fibre Channel HBA on a host.
  • {DESCRIPTION} This screen displays a diagram on the DS3500 single controller. {TRANSCRIPT} Here is a simplified architectural layout of a DS3500 that highlights some of the key enhancements to the controller. First, is the number of increased host interface connections. Each DS3500 controller has two 6 Gbps SAS host interfaces with the option to add two additional 6 Gbps SAS, four 8 Gbps FC or four 1 Gbps iSCSI host interfaces. As we all know, with more host connections, you have more “pipes” which data can pass through and therefore achieve greater throughput. Secondly, we have made a huge improvement with the PCI E 2.0 bus versus the earlier PCI-X bus between the ASIC and external interfaces providing 4Gb/s of internal bandwidth which supports significant overall storage system performance improvements. Next, the controller’s single 800 MHz Power PC Core processor provides built-in hardware XOR / P+Q for high-speed RAID parity calculations – enabling it to easily handle random, small-block I/O and deliver exceptional I/O per second performance to transaction-based applications. The I/O system core integrates the XOR engine and processor. While the processor focuses on data movement control, the high-speed XOR engine generates RAID parity. The controller has a single memory that is partitioned between the processor and data cache. Cache is also increased with up two 2 GB cache per controller which is also now destaged to a flash in the instance of a lengthy power outage the data from cache will remain protected. And with 6Gb SAS, the core processor has been updated with the 6Gbs SAS Power PC 440 ROC processor also often referred to as the Meteor chip. This super scalar core can support up to 1.5-GHZ scale. We have also replaced the earlier 24-port expander with a 36-port expander which greatly improves scalability of the DS3500. The DS3500 controller includes two SFF-8088 compliant 4x mini-SAS connections on the base board. It also supports a point-to-point SAS architecture for the disk side using the LSISAS2x36 expander to achieve direct contact with each drive, which helps to locate problem drives more quickly than parallel loop topology, where communication travels through each node.
  • {DESCRIPTION} This screen provides a top and bottom right-aligned 3-D images of the EXP3512 and EXP3524 enclosure units. {TRANSCRIPT} The EXP3512 and EXP3524 have a lot of the same characteristics. They are both 2U Storage Bridge Bay (SBB) compliant enclosures that can house two ESMs. With ESMs the support up to three SAS drive connections and they both support hot swappable customer replaceable units, or CRUs. The only key difference is the drives, the EXP3512 support 12 3.5-in drives and the DS3524 supports up to 24 2.5-in drives. These enclosures can also support multiple drive types when housed behind a DS3500. This supports a very efficient method of data storage whether its based on cost, capacity, performance, density or security.
  • {DESCRIPTION} This screen displays a rear view image of the EXP3512/EXP3524 ESMs and depicts its connection points. {TRANSCRIPT} This diagram is a quick look at the back of a fully configured expansion unit and this could be either the EXP3512 or the EXP3524. The OUT port located to far right of each EMS is used for chaining to the next enclosure. The two middle two connectors known as the IN ports (only one connection, to either, is supported).
  • {DESCRIPTION} This screen displays graphic images of a DS3500 storage unit and EXP3512 expansion units that are cabled together via the IN and OUT ports. {TRANSCRIPT} When cabling the EXP3512 and/or EXP3524 expansion units behind a DS3500 storage system, the cabling is the same as the DS3000 using the top-down and bottom-up cabling scheme to ensure accessibility to all drives in case of an ESM, controller or path failure. Each ESM includes three SFF-8470 compliant SAS 4-port wide miniSAS connectors for host and cascaded EMS connections through a 36 port expander that allows for direct contact with each drive. Two cables are used for various cabling topologies although you will find you will most often use just one as well as another connection for expansion. The EXP3512 and EXP3524 expansion units also support subsystem monitoring via SES over the SAS link as well as each enclosure meets the requirements of the Storage Bridge Bay 2.0 standard architecture. And like all the DS offerings, these enclosures are both RoHS and WEEE compliant. The diagram to your right shows a fully configured DS3500 storage system with seven EXP3512 expansion units. When cabling an ESM, the “Out” connector of one ESM must be cabled to the “In” connector of the next enclosure’s ESM. The One loop pair illustrated outlines the cabling required to ensure a multi-path highly available storage configuration. This “top-down/bottom-up” cabling scheme ensures that if any of the ESMs or a controller goes offline, access to all the enclosures and data continues without interruption. The DS3500 can support a mix of these enclosures with the only limitation that it can support up to a maximum of 96 drive slots. If you are cabling all EXP3524 expansion units (x24 drives), you would need only three behind the DS3500 to go up to 96 drives.
  • {DESCRIPTION} This screen displays a diagram located in the far right of a SAS technology point-to-point topology. It also includes a chart that lists drive types, throughput, RPM, and capacity. {TRANSCRIPT} Drive type intermix is a key feature of the DS3000 and DS3500 customers. With support for high performance SAS, Nearline SAS, full disk encryption SAS drives as well as 3.5-in and 2.5-in drive sizes, it is important to understand which drive can achieve maximum efficiencies. IBM DS3000 System Storage all implement a SAS technology which enables the system to accept both SAS hard drives and SATA hard drives. The point-to-point topology used in SAS configurations, as shown on the right, means that there is a direct path to each drive from each controller, so communication can take place directly, with no effects caused by an individual drive failure. The typical difference between SAS and SATA drives isn't just about the interface. SATA drives will suit those requiring the best price advantage for servers and storage deployments, and for customers who that are looking to increase storage capacity density and lowers the cost-per-gigabyte for Nearline and secondary storage applications. SAS drives will deliver the highest performance, reliability and software management compatibility, and are tailored to support mission-critical data in applications where performance, reliability and availability are key requirements. SAS also improves drive addressability and connectivity using an expander that enables one or more SAS host controllers to connect to a large number of drives.
  • {DESCRIPTION} This screen displays a SAS icon, a 3-D SAS configuration featuring server and storage units, and 3-D images of a SAS, SED SAS, and Nearline SAS drives. {TRANSCRIPT} The DS3500 can support high performance SAS and Nearline SAS – which is the new replacement for SATA and is offered at a comparable cost with improved performance. Also available is Full Disk Encryption SAS drives (also known as SED SAS) which secures data at rest. Both DS3500 enclosures can be intermixed behind a DS3500 allowing the widest array of drive type and size support and meeting an organization’s application, capacity, security as well as power consumption requirements. As always, when considering a drive purchase its first important to consider the cost. Both 2.5” and 3.5” drives of the same capacity and rpms and with drive costs alone, 2.5-in drives are a small percentage less. But when you factor in the Input/Output Operations Per Second (IOPs) performance, or cost savings from a power consumption perspective, or IOPs per watt, 2.5-in drives are therefore great for transactional applications where saving on annual energy expenditures is a key organizational initiative. Nearline SAS drives provide the same high capacity and low cost of SATA drives. At only about 3-4% more in cost, Nearline SAS drives are offered at the same capacity. Where Nearline SAS prevails over SATA is in performance and power providing improvements in sequential reads and random reads and writes, with substantial 140 improvement in sequential writes. Another benefit of Nearline SAS its great performance to power story as it delivers up to 38% the IOPs per Watt over SATA drives. So for every IOP of performance, Nearline SAS drives require less power. The full disk encryption, or SED, SAS drives is a newly introduced drive to IBM’s SAS-based storage systems. Full drive encryption (SED) provides data security at the most basic level, the hard drive. SED protects against many exposures and vulnerabilities all at once. Its government-grade encryption ensures data security in the event of a drive loss, theft or retirement. The SED engine performs encryption without a performance penalty, which allows organizations to achieve the highest levels of data security while retaining optimal performance.

  • {DESCRIPTION} This screen displays a diagram on the DS5300/DS5100 single controller. {TRANSCRIPT} Lets take a look at a controller to get a better understanding to its technology. At the very top of the diagram we have the host interface daughter card that provides 4 or 8 Gbps FC connection, which then connects to a special purpose ASIC. The ASIC chip handles the “heavy lifting” of RAID computation including built-in hardware-assist XOR for RAID 5 and P+Q for RAID 6 performance. Note that what appears to be a small element to the left of the ASIC chip; it is a de-staged to USB-based flash drives after power loss, and right below that, labeled a “management processor”, is a fairly powerful 2.8Ghz Xeon processor featuring 2 GB of dedicated memory. On the other side of the ASIC chip we have the option for 8 or 16 GB of dedicated cache with dynamic read and write allocation. Before we move on, lets take a minute to discuss how the cache and memory work in the system. We just mentioned that the management processor has its own memory or cache. Therefore, the management software running in the DS5100 and DS5300 does not use any of the customer’s storage controller cache – or any additional cache purchased, all of it is available for use with customer data. Now right below the ASIC chip we have two quad-ports 4 Gb FC drive-side chips, one chip is dedicated to local drive-side ports and the other dedicated to interconnect with the alternate controller. Finally at the bottom are the loop switches that connect to the drive-side chips. We will take a closer look at the feature later on in this topic. The ASIC chip appears to be the link that interfaces with the other components through multiple lanes of 2 GB/s PCI-E x8 busses.

EXP5000 uses the latest fibre channel and SATA technology to connect to DS5100 and DS5300 controllers through high-speed 4 Gbps FC disk expansion ports offering reliability and performance. It supports up to sixteen 4 Gbps 450 GB fibre-channel Enhanced Disk Drive Modules (E-DDMs) or 1 TB SATA E-DDMs, offering up to 7.03 terabytes (TB) of capacity per enclosure when using 450 GB fibre-channel E-DDMs and 16 TB when using 1 TB SATA E-DDMs. Coupled with the DS5100 or DS5300, you can configure RAID-protected storage solutions of up to 256 TB, providing economical and scalable storage for your rapidly growing application needs for limited access, data reference storage capacity. It is also possible to mix SATA and FC drives in the same enclosure.
  • {DESCRIPTION} This screen contains a drawing of the EXP5000 drive casing, and an image of a SSD located in the far right corner of the screen. It also contains a drawing at the bottom of the screen of a mixture of SATA, SSD, FDE, and FC drives together. {TRANSCRIPT} EXP5000s connect to DS5100 and DS5300 controllers through high-speed 4 Gbps FC disk expansion ports and have a physical storage capacity of up to 16 TB per enclosure, using 1000 GB SATA DDMs (disk drive modules) and up to 9.6 TB per enclosure, using 600 GB FC DDMs. This also allows the intermixture of SATA, FC and SSD in the same drawers. Fibre Channel Solid State drives provides significantly higher IOPS than traditional hard disk drives with rotating media, with up to an 80 times improvement for small-block I/O. SSD drives also use less power (up to 80% lower), and when combined with their improved performance the power and rack space reductions are dramatic
  • {DESCRIPTION} This screen displays graphic images of a DS5300 and DS5100 storage unit and sixteen EXP5000 expansion units that are cabled together via a Drive loop connection. {TRANSCRIPT} Cabling enclosures using drive loops helps to reduce latency and ensure data access by providing an alternate path in case of a port failure on either the controller or an expansion drawer. Using EXP5000 expansion drawers, the DS5100 and DS5300 are capable of supporting 128-drive configuration using 16 drive per dual-loop, a 256-drive configuration using 32 drives per dual-loop, and finally for maximum configuration 448 drives with 64 drives per dual-loop for those customers requiring massive amounts of storage as indicated in the cabling topology shown on the right.
  • {DESCRIPTION} This screen displays images of the EXP5060 Drive enclosure front and rear view, and a 3-D drawings of the enclosure. {TRANSCRIPT} The EXP5060 expansion unit is a high density disk enclosure designed to provide the DS5300 and DS5100 with maximal rack density while preserving data availability. The EXP5060 accommodates up to 60 3.5” SATA disk drives on five drawers within a rack-mount 4U enclosure. Each 12-drive drawer can be extended while its drives remain active, allowing for individual drives to be replaced without affecting the operation of other drives. Up to eight EXP5060 disk enclosures can be attached to a DS5100 or DS5300 controller; providing up to 480 physical drive storage. EXP5060 expansion enclosures can be intermixed with EXP5000 expansion enclosures, as long as the 448 drive maximum is maintained. With its high density format and amount of disks, the EXP5060 will deliver beneficial performance for HPC capacity intensive application environments, and with its efficient power supplies and variable speed cooling fans, it is a real energy saver.
  • {DESCRIPTION} This screen displays a close-up image of the EXP5060 drive enclosure drawers. It also contains close-up of drawer 5 showing its 12 drive bays. {TRANSCRIPT} As we just mentioned, each the EXP5060 drawer can house 12 SATA disk drives, for a total of 60 disks. There are service and status LEDs on the front panel for the EXP5060; as well as drive activity and service LEDs on the front of each drawer for each drive location in it. Each drawer interfaces to the Environmental Service Modules (ESM) through an interconnect midplane. For required airflow, a minimum of four drives must be installed in each drawer in the front 4 drive bays (such as 1,4,7 and 10). This requirement places the minimum configuration of this expansion at twenty disks. The first image identifies the drawer numbering scheme and the second images shows the drive slots locations in the drawer, and the location of the four required drives. EXP5060 full chassis weight is 250lbs, therefore, for safety reasons, it should not to be installed in any rack above the 32U. When installing the chassis into the rack it is required to use a portable lift tool to install or remove the chassis from the cabinet.
  • {DESCRIPTION} This screen displays a close-up image of the EXP5060 drive and drive casing. {TRANSCRIPT} The SATA drive modules supported by the EXP5060 are not the same as the SATA drives supported by the EXP5000. The EXP5060 has a fiber to ATA translator built into the ESMs and does not require the use of the interposer card on the disk modules. Additionally, with the horizontal mounting of the drive in the drawer, a unique carrier is introduced with these modules.
  • {DESCRIPTION} This screen displays a rear view image of the EXP5060 and ESM unit. {TRANSCRIPT} The rear of the EXP5060 Expansion contains two uniquely designed Environmental Service Modules (ESM) that adds both hardware and firmware to support the trunking capability. It contains 2 FC ports (1A and 1B ports), and a second level (2A and 2B ports for trunking) of fiber switching designed into them as well as a device control manager (DCM) which manages the device IO operations. It also features LED status indicators, a Seven Segment Display, and serial maintenance connections. These features play a critical part in the handling, managing, and throughput capabilities of these expansion. It has two redundant hot-swappable 180-240V AC voltage power supplies with, and dual fan assemblies to handle the increased drive count and therefore require a 208VAC circuit.
  • {DESCRIPTION} This screen displays graphic images of a DS5300 and DS5100 storage unit and four EXP5060 expansion unit that are cabled together showing a non-trunking configuration and a trunking configuration. {TRANSCRIPT} The EXP5060 enclosure can be configured in a number of different configurations, however, all basically conforms to two major styles; the non-trunked and trunked configurations. A non-trunked environment can create an environment for shared workloads with fiber channel drives and large SATA capacity needs. In the non-trunked environments, the EXP5060 can be installed in the standard configuration with one EXP5060 per loop pair installed on each of the DS5100 or DS5300 loop pairs. In this configuration the system can reach its maximum configuration of eight EXP5060’s. To support this maximum configuration a special feature key must be added to the DS5100 or DS5300 storage subsystems. The EXP5060 expansions can also be combined with EXP5000 expansions. However, no EXP5000’s can be included with the EXP5060 in a maximum configuration. Trunking doubles access points to enclosure by providing two loop pairs for dedicated high throughput environments to support large streaming applications. Only the EXP5060 can trunked. For an optimal configuration a total of four EXP5060’s can be used to drive the full bandwidth of all the eight backend channels. It is automatically “enabled” or “disabled” by cabling. It is also possible to design a cascaded trunked configuration with up to the full eight EXP5060’s attached. However, there is no real throughput enhancement over the full non-trunked configuration. The cascaded configuration of the two EXP5060’s per trunked channel pair results in the same number of disks being addressed per channel pair as it would in the non-trunked environment, and therefore the same number of active disks are possible.
  • {DESCRIPTION} This screen displays drawings of a DS5300 and DS5100 storage unit and eight EXP5020 expansion units that are cabled together showing a non-trunked configuration. {TRANSCRIPT} This diagram illustrates a single unit per port cabling for a full non-trunked eight EXP5060 configuration. This type of configuration can be easily copied for each of the eight expansions on the port pairs for a full configuration.
  • {DESCRIPTION} This screen displays drawings of a DS5300 and DS5100 storage unit and four EXP5020 expansion units that are cabled together showing a trunked configuration. {TRANSCRIPT} This diagram illustrates a DS5300 in a four EXP5060 trunked configuration. This configuration provides the ability to trunk the expansion across four loops to get full throughput of a pair of channels, making it possible to achieve over 6GBps for the DS5300 subsystem.
  • {DESCRIPTION} This screen lists the topic agenda. {TRANSCRIPT} Next, we will introduce the IBM System Storage DS3000 Storage Manager and the DS Storage Manager software, and discuss it’s supported features and functions, as well as the benefit of simplify, configure, manage, and troubleshooting the DS disk system.
  • {DESCRIPTION} This screen displays screenshots of the DS3000 Storage Manager interface. {TRANSCRIPT} The IBM DS Storage Manager is used to manage the DS3200, DS3300, and DS3400 storage subsystems. Along with your storage subsystem, you get the DS Storage Manager Software and Host Kit CDs; otherwise, you can download it from the IBM support website. Using DS Storage Manager software, you can perform tasks such as creating arrays and logical drives, assigning logical drives to the host servers, setting up FlashCopy and VolumeCopy, capturing logs for troubleshooting, and so on.
  • {DESCRIPTION} This screen shot list the DS3000 Series Advanced features. {TRANSCRIPT} The extended advanced features are listed, includes part numbers. This diagram describes Out of the Box or premium features, and shows you all current advanced features that are optional and currently available on the DS3000 series. The DS3200 Software Feature Pack, DS3300 Software Feature Pack, DS3400 Software Feature Pack, and the EXP3000 Expansion License have been incorporated into the base models and are no longer needed as prerequisites to the other advanced function options. The required controller firmware that enables this function must be at firmware level V06.70.23.00 or later and is available on the DS3000 product support Web site, or you can also refer to the IBM System Storage DS3000 series Interoperability Matrix, found at the following URLs listed below.
  • {DESCRIPTION} This screen displays screenshots of the DS Storage Manager interface. {TRANSCRIPT} DS Storage Manager is used to manage the DS5000 series and the DS3500, the first entry storage system to be offered with DS Storage Manager software. The DS Storage Manager combines the simplicity of the DS3000 Storage Manager and the robustness and power of the DS Storage Manager previously only reserved for the DS5000. The DS Storage Manager is both intuitive but does not sacrifice storage system control. The DS Storage Manager ensures an intuitive and powerful user experience. Its feature-rich management software helps ensure high performance, great utilization and uninterrupted data availability. It achieves this through an easy-to-understand user interface and wizards and can provide unparalleled configuration flexibility enabling superior utilization. And this flexibility allows you to tune your storage system to dynamically meet your server, application and workload requirements. And as we mentioned, high availability is a key attribute of an external storage system to ensure data is accessible 24 by 7. The DS Storage Manager supports high availability with online configuration, reconfiguration, expansion, and maintenance tasks. Automated I/O path failover, drive rebuild, and cache de-stage also ensures that if a power loss or a drive or component failure occurs, the system storage stays online. And with integrated disk encryption and RAID 6, your customer has further assurance that their data will not only stay online and be protected, but that it is also secure. And finally, the DS Storage Manager provides the same full line of fully-integrated advanced functionality premium features as the DS3000 Storage Manage, but in addition includes Remote Mirroring across FC host ports of the DS3500 and DS5000 Series.
  • {DESCRIPTION} This screen displays contains on the DS3000 and DS Storage Manager dynamic capabilities. {TRANSCRIPT} DS3000 and DS Storage Manager dynamic capabilities are now available via the user interface. This includes online capacity expansion, also referred to as EXP hot add technology. Dynamic capacity expansion allows you to add drives to existing volume groups and automatically restripes the volumes. One of the newest feature to the user interface, is DVE, or dynamic volume expansion. This feature allows you to expand available capacity to existing volumes that may need more space. Be sure to check if your customer’s operating system supports this feature. Dynamic RAID level migration, which is also available via the user interface, allows you to on-the-fly change an existing RAID level to better meet the application and data requirements. And dynamic segment size migration, can now be changed without relocating the data. Finally, with host mirroring now supported across FC host ports, the dynamic mode switching features is supported and allows for the changing between remote mirror modes.
  • {DESCRIPTION} This screen displays an image of a slinky in motion. {TRANSCRIPT} Flexibility was key in the development of the DS Storage Manager. This allows the user to tune multiple attributes to meet almost any application requirement. This includes support for multiple RAID levels which not all the competition can support, as well as, multiple drive types capacities, form factors and rotational speeds. And with multiple RAID levels, multiple RAID sizes can also be supported. This includes up to 48 plus 48 drives for RAID 1 and 10, as well as, 29 plus 1 drive with RAID levels 3, 5, and 6. This provides for great IOPS performance with data being written across a maximum number of spindles. DS3000 Storage Manager and DS Storage Manager also support one or more volumes per RAID group and settings can also be defined on a volume-by-volume basis to ensure maximum performance, capacity and availability for each volume. And finally dynamic configuration and re-configuration is supported allowing for automatic configurations if and when needed with no impact to storage IO.
  • {DESCRIPTION} This screen displays a 3-D drawing of a DACstore with usable storage. {TRANSCRIPT} The DS3000, DS3500, DS3950 and DS5000 controllers store configuration metadata in a private region on every configured drive called the DACstore. Storing metadata in the nonvolatile DACstore provides the highest availability and enables controller-level upgrades and drive-level reconfigurations as system requirements change. The entire system can be upgraded when a capacity or performance boost is desired. Drives can be relocated within the storage system to improve channel utilization/protection or even migrated as a complete volume group into another storage system. And in each instance, all configuration and user data remains intact on the drives. This allows for drives not to bound to a given enclosure or slot and can be relocated within a system to improve channel utilization such as with performance or availability. Individual volume groups can be migrated to another system and full systems can also be upgraded by simply replacing the controllers. Higher availability is also ensured and this critical configuration data is stored on every drive, not just one or two of a volume group.
  • {DESCRIPTION} This screen displays a 3-D diagram illustrating Storage Partitioning. {TRANSCRIPT} With storage partitioning, different server types, operating systems and applications come together in a single consolidated storage system. The result is a reduced footprint and much less need for real estate and associated operating expenses; optimized utilization (especially through increased functionality for low-end servers); enhanced reliability and security; and improved efficiencies for you as the administrator. Benefits of partitioning include more efficient storage utilization and management in which capacity can be easily allocated to servers as needed and you spend less time and money managing storage -- fewer storage systems needed to support many servers. Partitioning includes improved storage flexibility in which you can easily add storage, new servers or retire older servers without storage unload/reload or downtime.
  • {DESCRIPTION} This screen displays a 3-D FlashCopy topology illustrating point-in-time replication. {TRANSCRIPT} FlashCopy provides an additional level of data protection and the means to improve production data utilization. FlashCopy images enable non-production, backup or analysis servers to access an up-to-date copy of production data while the production data remains online and accessible to the user. FlashCopy can be used to create a virtual logical drive that is a point-in-time (PiT) image of a real logical drive with all the read, write and copy capabilities of the original. The snapshot volume appears and functions as a standard volume. It can be used as a backup source, restoration point, information analysis/manipulation base, development environment, and for other applications that benefit from a Volume Copy. Using the FlashCopy also requires the use of less physical disk space, because it makes use of a repository logical drive for storing only data change operations that have been made since its creation. Because the FlashCopy is not a full physical copy, if the source logical drive is damaged, the FlashCopy logical drive itself cannot be used to recover it.
  • {DESCRIPTION} This screen displays a 3-D VolumeCopy topology illustrating point-in-time replication. {TRANSCRIPT} Volume Copy creates an exact duplicate, or clone, of the production data which can be mapped to a separate server for analysis. The clone can be used for application testing or development, information analysis, data mining, or backup/restoration. Volume Copy also can be used to redistribute data (moving volumes from older, slower disk drives to newer, faster or higher capacity drives), to optimize performance, storage density or capacity utilization.
  • {DESCRIPTION} This screen displays a 3-D ERM/Remote mirroring topology illustrating volumes being mirrored. {TRANSCRIPT} Enhanced Remote Mirroring (ERM) or Remote mirroring adds another replication feature that is ideally-suited for business continuity and disaster recovery. The remote mirroring premium feature protects the information stored on the DS3500 and Mid-range storage systems through real-time data replication to an off-site system. It is generally used to migrate data from one subsystem to another, or it is used as the remote mirroring engine for their disaster recovery solution (DR) between two site locations over varying distances. In the event of disaster or unrecoverable error at one storage subsystem, you can promote the second storage subsystem to take over responsibility for normal I/O operations. This secondary system can be either another DS3500 or DS5000 which supports great ease-of-use as well investment protection if you may have already have these system in existence. For each set of volumes that comprise a mirror pair, RVM supports a variety of replication options to provide you with the flexibility to optimize data protection and utilization to includes a secondary backup device at a remote site. This feature is not supported on the IBM DS3200, DS3300 or DS3400 entry-level storage units.
  • {DESCRIPTION} This screen displays contains on the ERM/Remote mirroring key features. {TRANSCRIPT} And here are a couple of the key features of remote mirroring. This includes Synchronous, asynchronous and WOC mirroring modes, Dynamic mode switching without suspending the mirror, Suspend / resume mirroring with delta resynchronization, and Read-only mirror access which includes FlashCopy creation.
