The TotalStorage® DS8000 series is designed to provide unmatched functionality, flexibility, and performance for enterprise disk storage systems at new levels of cost effectiveness. The DS8000 series incorporates IBM's POWER5 processor technology either in a dual two-way processor-complex offering, the DS8100 Model 921 or, for customers requiring additional performance or capacity, two dual four-way processor-complex offerings, the DS8300 Models 922 and 9A2. The DS8300 Model 9A2 further demonstrates IBM's unique ability to converge server and storage technologies by enabling the creation of multiple IBM TotalStorage Storage System LPARs (Logical Partitions). These Storage System LPARs can be used for completely separate production or test environments in a single physical system. This may enable you to purchase one storage server in environments where more than one may have been needed in the past.
The DS8000 series uses the highly reliable and functional microcode base of the TotalStorage Enterprise Storage Server (ESS) Model 800, on top of a new, leading-edge, modular hardware design. This innovative design incorporates a high-bandwidth internal fabric designed to support fault tolerance, highly expandable and flexible processor memory, and the latest in Fibre Channel attached disks. It has a dual-processor complex implementation that supports concurrent microcode loads, transparent I/O failover and failback support, and redundant, hot-swappable components to help support 24 x 7 business environments. The maximum host I/O operations per second of a DS8300 is up to six times the maximum of an ESS Model 800, so that you can easily consolidate your workload into a single storage subsystem. The DS8100 and DS8300 also offer all new power and packaging which takes 20 percent less floor space than a base ESS Model 800.
The DS8000 series extends the advantages offered by IBM's TotalStorage Resiliency Family technologies, including FlashCopy®, Global Mirror, Metro Mirror, as well as other mirroring functions supported by the ESS Model 800. The DS8000 series also provides z/OS® performance capabilities provided by Parallel Access Volumes (PAV), I/O Priority Queuing, and Multiple Allegiance.
The DS8100 offers scalability of physical capacity from 1.1 to 115.2 TB, while the DS8300 offers a maximum capacity of 192 TB. Fibre Channel disks are available in 73 GB, 146 GB, and 300 GB capacities and these will be intermixable within a single system. Thus, you can better tailor your disk storage configuration to cost effectively address capacity and performance requirements. RAID-5 as well as RAID-10 are both intermixable within a single system.
The DS8000 series offers a wide range of management functionality and flexibility to help I/T
organizations more easily manage their storage environments. These systems come standard with the
IBM TotalStorage DS Storage Manager, an all new, easy-to-use, high-function GUI-based manager for

High-performance disk storage for business-critical enterprise workloads
The IBM TotalStorage DS8000 series is a new high-performance, high-capacity series of disk storage devices. It is designed to extend upon the functionality, stability, and reliability of the current IBM TotalStorage Enterprise Storage Server. The DS8000 series incorporates IBM's POWER5 processor technology in a dual two-way processor-complex offering, the DS8100 Model 921, or for customers requiring additional performance or capacity, two dual four-way processor-complex offerings, the DS8300 Models 922 and 9A2. These models are designed to offer higher performance, additional capacity, increased addressing capabilities, and additional enhancements versus the ESS Model 800. In addition, the DS8300 Model 9A2 further demonstrates IBM's unique ability to converge server and storage technologies by enabling the creation of multiple IBM TotalStorage Storage System LPARs (Logical Partitions).
New technology for high performance, reliability, and enhanced connectivity
The DS8000 series features the following hardware and technology that can enhance performance, connectivity, and reliability:
- POWER5 processor technology: The DS8000 series features IBM's POWER5 server technology to help support high performance. The maximum host I/O operations per second of the DS8300 Model 922 or 9A2 is up to six times the maximum of an ESS Model 800.
- Multiple Storage System Logical Partitions (LPARs): The DS8300 Model 9A2 supports two Storage System LPARs, each with their own resources. This may enable you to purchase one storage server in environments where more than one may have been needed in the past.
- Industry-standard Fibre Channel disk drives: The DS8000 series offers a selection of Fibre Channel disk drives, including 300 GB drives, allowing a DS8100 to scale up to 115.2 TB of capacity and a DS8300 to scale up to 192 TB of capacity.
- Four-port Fibre Channel/FICON adapters: These new adapters are designed to not only enhance connectivity, but increase configuration flexibility because the individual ports can be configured to support Fibre Channel or FICON.
- New processor memory offerings: The DS8100 offers up to 128 GB of processor memory and the DS8300 offers up to 256 GB of processor memory. In addition, the Non-Volatile Storage (NVS) scales to the processor memory size selected, which can also help optimize performance. Improved caching algorithms can also help enhance performance versus the ESS Model 800 through new technologies for managing cache space.
- More host attachments than the ESS Model 800: The DS8100 offers up to 16 host adapters and the DS8300 offers up to 32 host adapters. This can be an intermix of ESCON® and Fibre Channel/FICON adapters, further increasing your ability to share your disk storage.
- New internal fabric: The DS8000 series features a new internal fabric which can help provide increased bandwidth.
- High availability: The DS8000 series is designed and implemented with component redundancy to help avoid many potential single points of failure.
Functional enhancements for flexibility and ease-of-use
The DS8000 series offers functional enhancements and new capabilities that are designed to increase flexibility and usability.
Logical Unit Number (LUN) and volume management
- Non-disruptive LUN and volume creation and deletion are now supported. When a LUN or volume is deleted, the capacity can be re-formatted and re-used.
- LUNs and volumes can be configured to span arrays. Therefore, the size of the volume/LUN is not constrained by the size of the array. LUNs up to 2 TB are supported. CKD volumes up to 65,520 cylinders are supported.
Addressing capabilities: More Logical Subsystems (LSS), logical devices, and logical paths can be defined versus the current ESS.
- Up to 256 LSS
- Up to 65,280 logical devices
- Up to 130,560 FICON logical paths (512 logical paths per control unit image)
- Up to 8,000 process logins (509 per SCSI-FCP port)
These addressing boundaries are extended to each storage image in a DS8300 Model 9A2.
Simplified storage management for zSeries® with z/OS: For zSeries and z/OS environments, the DS8000 series can support a new 65,520 cylinder 3390 volume. This new volume option has a capacity of approximately 55.7 GB. It can help relieve addressing constraints, improve disk resource utilization, and improve storage administrator productivity by providing the ability to consolidate multiple disk volumes into a single address.
Administration and management
- New online and offline configuration capability features an all-new Web-based graphical user interface (GUI) designed to offer increased ease of use.
- A single command line interface (CLI) supports both logical configuration and copy services.
Technology and packaging: The DS8000 series features new technology, packaging, and capabilities designed to help improve availability and reduce costs.
- New packaging allows a single DS8100 or DS8300 base frame to take up to 20% less floor space than an ESS base frame. This can help reduce your costs for valuable floor space.
- Capabilities such as remote code distribution and e-mail notification of link failures can also improve availability.
Choice of models to meet your performance and configuration needs
The DS8000 series features several models in a new, higher-density footprint than the ESS Model 800, providing configuration flexibility.
The DS8100 Model 921 offers a dual two-way processor complex and holds up to 128 disk drives for a maximum capacity up to 38.4 TB. It also supports up to 128 GB of processor memory and up to 16 ESCON or Fibre Channel/FICON adapters. With an optional expansion unit (DS8000 Model 92E), a single DS8100 Model 921 solution supports up to 384 disk drives, for a total capacity of up to 115.2 TB.
The DS8300 Model 922 offers a dual four-way processor complex and holds up to 128 disk drives for a maximum capacity of up to 38.4 TB. It also supports up to 256 GB of processor memory and up to 16 ESCON or Fibre Channel/FICON adapters. With one or two optional expansion units, it scales as follows:
- With one DS8000 Model 92E expansion unit, the DS8300 Model 922 supports up to 384 disk drives, for a maximum capacity of up to 115.2 TB, and up to 32 ESCON or Fibre Channel/FICON adapters.
- With two DS8000 Model 92E expansion units, the DS8300 Model 922 supports up to 640 disk drives, for a maximum capacity of up to 192 TB, and up to 32 ESCON or Fibre Channel/FICON adapters.
The DS8300 Model 9A2 offers a dual four-way processor complex and supports the use of two Storage System LPARs. It holds up to 128 disk drives for a maximum capacity of up to 38.4 TB. It also supports up to 256 GB of processor memory and up to 16 ESCON or Fibre Channel/FICON adapters. With one or two optional DS8000 Model 9AE expansion units, it scales as follows:
- With one DS8000 Model 9AE expansion unit, the DS8300 Model 9A2 supports up to 384 disk drives for a maximum capacity of up to 115.2 TB, and up to 32 ESCON or Fibre Channel/FICON adapters.
- With two DS8000 Model 9AE expansion units, the DS8300 Model 9A2 supports up to 640 disk drives, for a maximum capacity of up to 192 TB, and up to 32 ESCON or Fibre Channel/FICON adapters.
Depending on workload, the maximum host I/O operations per second of the DS8100 Model 921 is up to three times the maximum of the ESS Model 800, and the maximum host I/O operations per second of the DS8300 Model 922 or 9A2 is up to six times the maximum of the ESS Model 800. This may allow you to consolidate workload from multiple Model 800s or Model F20s to a single DS8100 or DS8300 system.
Storage System Logical Partitions (LPARs) enhance flexibility
The DS8300 Model 9A2 exploits LPAR technology, allowing you to run two separate storage server images. Each Storage System LPAR has access to:
- 50 percent of the processors
- 50 percent of the processor memory
- Up to 16 host adapters
- Up to 320 disk drives (up to 96 TB of capacity)
With these separate resources, each Storage System LPAR can run the same or different versions of microcode, and can be used for completely separate production, test, or other unique storage environments within this single physical system. This may enable storage consolidations where separate storage subsystems were previously required, helping to increase management efficiency and cost effectiveness.
A variety of configuration options
Physical capacity for the DS8000 series is purchased via disk drive sets. A disk drive set contains 16 identical disk drives (same capacity and rpm). Disk drive sets are available in 73 GB (15,000 rpm), 146 GB (10,000 rpm), and 300 GB (10,000 rpm). For additional flexibility, feature conversions are available to exchange existing disk drive sets when purchasing new disk drive sets with higher capacity. Price, performance, and capacity flexibility to help meet specific application and business requirements is provided through support for the intermix of 73 GB, 146 GB, or 300 GB drives.
IBM Standby Capacity On Demand offering for the DS8000
The IBM Standby Capacity On Demand for DS8000 (Standby CoD) offering allows inactive disk drives to be installed that can be easily activated as business needs require.
IBM offers capacity on demand solutions that are designed to meet the changing storage needs of rapidly growing e-businesses. The Standby CoD offering is designed to provide you with the ability to tap into additional storage and is particularly attractive if you have rapid or unpredictable growth, or if you simply want the knowledge that the extra storage will be there when you need it.
With this offering, up to four Standby CoD disk drive sets (64 disk drives) can be factory or field installed into your system. To activate, you simply logically configure the disk drives for use a nondisruptive activity that does not require intervention from IBM. Upon activation of any portion of a Standby CoD disk drive set, you must place an order with IBM to initiate billing for the activated set. At that time, you can also order replacement Standby CoD disk drive sets.
As with the IBM Standby Capacity on Demand for ESS offering, this offering also allows you to purchase licensed functions based upon your machine's physical capacity excluding unconfigured Standby CoD capacity. This can help improve your cost of ownership since your extent of IBM authorization for licensed functions can grow at the same time you need your disk capacity to grow.
To further improve your cost of ownership, this offering does not have an offering fee premium.
A Standby CoD disk drive set must be activated within a 12-month period from the date of installation; all such activation is permanent. Contact your IBM representative to obtain additional information regarding Standby CoD offering terms and conditions.
Flexibility with support for RAID-5 and RAID-10
With the DS8000 series, physical capacity can be configured as RAID-5, RAID-10, or a combination of both. RAID-5 can offer excellent performance for most applications, while RAID-10 can offer better performance for selected applications, in particular, high random write content applications in the open systems environment. RAID-10 combines RAID-1 (mirroring) with RAID-0 (striping). Each drive within a RAID-10 array is mirrored to a second drive within the array, and to optimize performance, data is striped across the drives within the array.
The decision to configure capacity as RAID-5 or RAID-10, as well as the amount of capacity to configure for each type, can be made at any time. RAID-5 and RAID-10 arrays can be intermixed within a single system and the physical capacity can be logically reconfigured at a later date (for example, RAID-5 arrays can be reconfigured into RAID-10 arrays).
Enhanced connectivity with four-port Fibre Channel/FICON Host Adapters
The DS8000 series is designed to offer enhanced connectivity with the availability of four-port Fibre Channel/FICON Host Adapters. The 2Gb Fibre Channel/FICON Host Adapters, which are offered in long-wave and shortwave, auto-negotiate to either 2Gb or 1Gb link speeds. This flexibility enables the ability to exploit the potential benefits offered by higher performance, 2Gb SAN-based solutions, while also maintaining compatibility with existing 1Gb infrastructures. In addition, the individual ports on the adapter can be configured with Fibre Channel Protocol (FCP) or FICON. This can help protect your investment in Fibre Channel adapters, and increase your ability to migrate to new servers. The DS8000 series also offers two-port ESCON adapters. A DS8100 Model 921 can support up to a maximum of 16 host adapters which equates to a maximum of 64 Fibre Channel ports or a maximum of 32 ESCON ports. A DS8300 Model 922 or 9A2 can support up to a maximum of 32 host adapters which equates to a maximum of 128 Fibre Channel ports or a maximum of 64 ESCON ports.
The DS8000 series offers extensive connectivity support including Fibre Channel, FICON, or ESCON across a broad range of server environments including IBM zSeries, pSeries®, p5, iSeries, i5, and xSeries® servers, servers from Sun and Hewlett-Packard, and non-IBM Intel-based servers. This rich support of heterogeneous environments and attachments, along with the flexibility to easily partition the DS8000 series storage capacity among the attached environments, can help support storage consolidation requirements and dynamic, changing environments.
Rich set of business continuance solutions
The DS8000 series supports a rich set of copy service functions and management tools that can be used to build solutions to help address business continuance requirements.
Point-in-time copy solutions: IBM TotalStorage FlashCopy is designed to provide a point-in-time copy capability for logical volumes. FlashCopy creates a physical point-in-time copy of the data, with minimal interruption to applications, and makes it possible to access both the source and target copies immediately.
FlashCopy supports many advanced capabilities, including:
- Data Set FlashCopy: Allows a FlashCopy of a data set in a zSeries environment.
- Multiple Relationship FlashCopy: Allows a source to have FlashCopy relationships with multiple targets simultaneously. This flexibility allows you to initiate up to 12 FlashCopy establishes on a given logical unit number (LUN), volume, or data set, without needing to first wait for or cause previous relationships to end.
- Incremental FlashCopy: Provides the capability to "refresh" a LUN or volume involved in a FlashCopy relationship. When a subsequent FlashCopy establish is initiated, only the data required to bring the target current to the source's newly established point-in-time is copied. The direction of the "refresh" can also be reversed, in which case the LUN or volume previously defined as the target becomes the source for the LUN or volume previously defined as the source (and now the target).
- FlashCopy To A Remote Mirror Primary: Lets you establish a FlashCopy relationship where the target is also a remote mirror primary volume. This enables you to create full or incremental point-in-time copies at a local site and then use remote mirroring commands to copy the data to the remote site.
- Consistency Group Commands: Allows DS8000 series systems to hold off I/O activity to a LUN or volume until the FlashCopy Consistency Group command is issued. Consistency groups can be used to help create a consistent point-in-time copy across multiple LUNs or volumes, and even across multiple DS8000s.
- Inband Commands Over Remote Mirror Link: In a remote mirror environment, commands to manage FlashCopy at the remote site can be issued from the local or intermediate site and transmitted over the remote mirror Fibre Channel links. This eliminates the need for a network connection to the remote site solely for the management of FlashCopy.
FlashCopy is an optional feature of the DS8000 series, and is available with the point in time indicator feature number 0720 and corresponding DS8000 series function authorization (2244-PTC with #72xx).
Remote mirror and copy solutions: The DS8000 series supports several hardware-based remote mirror and copy solutions:
- IBM TotalStorage Metro Mirror: This solution is designed to provide real-time mirroring of logical volumes between two systems that can be located up to 300 km from each other. It is a synchronous copy solution where write operations are completed on both copies (local and remote site) before they are considered to be done.
- IBM TotalStorage Global Copy: This is a non-synchronous long-distance copy option for data migration and backup.
IBM TotalStorage Global Mirror: Global Mirror is a long-distance remote copy solution across two
sites using asynchronous technology and is designed to provide the following:
- Support for virtually unlimited distance between the local and remote sites, with the distance typically limited only by the capabilities of the network and channel extension technology being used. This can better enable you to choose your remote site location based on business needs and enables site separation to add protection from localized disasters.
- A consistent and restartable copy of the data at the remote site, created with little impact to applications at the local site.
- Data currency where, for many environments, the remote site lags behind the local site an average of 3 to 5 seconds, minimizing the amount of data exposure in the event of an unplanned outage. The actual lag in data currency experienced will depend upon a number of factors, including specific workload characteristics and bandwidth between the local and remote sites.
- Dynamic selection of the desired Recovery Point Objective (RPO) based upon business requirements and optimization of available bandwidth.
- Session support whereby data consistency at the remote site is internally managed across up to eight systems located across the local and remote sites.
- Efficient synchronization of the local and remote sites with support for failover and failback modes, helping to reduce the time required to switch back to the local site after a planned or unplanned outage.
All of the above remote mirroring solutions use Fibre Channel as the communications link between the primary and secondary machines. The Fibre Channel ports used for remote mirror and copy can be configured as either a dedicated remote mirror link or as a shared port between remote mirroring and Fibre Channel Protocol (FCP) data traffic.
The remote mirror and copy solutions listed above are optional capabilities of the DS8000 series. They are available with the remote mirror and copy indicator, feature number 0740 and corresponding DS8000 series function authorization (2244-RMC with #74xx). The DS8000 series system can participate in remote mirror and copy solutions with the ESS Model 750, ESS Model 800, and DS6000 series systems.
Remote mirror and copy solutions for z/OS: Following are two remote mirror and copy solutions for the z/OS environment for the DS8000 series:
- IBM TotalStorage z/OS Global Mirror: This is a combined hardware and software business continuance solution for the zSeries environment providing asynchronous mirroring between systems at two sites located global distances apart. z/OS Global Mirror is an optional capability of the DS8000 series, and is available with the remote mirror for z/OS indicator, feature number 0760 and corresponding DS8000 series function authorization (2244-RMZ with #76xx).
- z/OS Metro/Global Mirror (three-site z/OS Global Mirror and Metro Mirror): This mirroring capability utilizes z/OS Global Mirror to mirror primary site data to a location that is a long distance away and also uses Metro Mirror to mirror primary site data to a location within the metropolitan area. This enables a three-site high availability and disaster recovery z/OS solution for even greater protection from unplanned outages. z/OS Metro/Global Mirror is an optional capability of the DS8000 series, and is available with the remote mirror for z/OS indicator, feature number 0760 and corresponding DS8000 series function authorization (2244-RMZ with #76xx) and the remote mirror and copy indicator, feature number 0740 and corresponding DS8000 series function authorization (2244-RMC with #74xx).
IBM performance innovations for the zSeries environments
The DS8000 series supports the following previously introduced IBM performance innovations for zSeries environments.
FICON extends the ability of the DS8000 series system to deliver high bandwidth potential to the logical volumes needing it, when they need it. Older technologies are limited by the bandwidth of a single disk drive or a single ESCON channel, but FICON, working together with other DS8000 series functions, provides a high-speed pipe supporting multiplexed operation.
Parallel Access Volumes (PAV) enables a single zSeries server to simultaneously process multiple I/O operations to the same logical volume, which can help to significantly reduce device queue delays. This is achieved by defining multiple addresses per volume. With Dynamic PAV, the assignment of addresses to volumes can be automatically managed to help the workload meet its performance objectives and reduce overall queuing. PAV is an optional feature on the DS8000 series, available with the PAV indicator feature number 0780 and corresponding DS8000 series function authorization (2244-PAV with #78xx).
Multiple Allegiance expands the simultaneous logical volume access capability across multiple zSeries servers. This function, along with PAV, enables the DS8000 series to process more I/Os in parallel, helping to improve performance and enabling greater use of large volumes.
I/O priority queuing allows the DS8000 series to use I/O priority information provided by the z/OS Workload Manager to manage the processing sequence of I/O operations.
New licensing capabilities for copy functions to reduce costs
With the DS8000 series, new licensing options are available for users of FlashCopy (point in time copy #0720) and remote mirror and copy (#0740) as follows:
- If the function is used with open systems data only, a license is required for only the total physical capacity configured as Fixed Block (FB).
- If the function will be used with zSeries data only, a license is required for only the total physical capacity configured as Count Key Data (CKD).
- If the function is used with both open systems and zSeries data, a license is required for the total physical capacity of the DS8000 series system.
In addition, the license scope (FB, CKD, or entire machine) is client managed through an IBM Web-based application. This allows you to change the license scope on a given machine as your business requirements change.
Management tools and utilities to improve administrator productivity
The DS8000 series supports the following management tools and utilities:
IBM TotalStorage Management Console for the DS8000: The Management Console is the focal point for configuration, copy services management, and maintenance activities. The Management Console is a dedicated workstation that is physically located (installed) inside your DS8100 and DS8300 and can proactively monitor the state of your system, notifying you and IBM when service is required. It can also be connected to your network to enable centralized management of your system using the IBM TotalStorage DS Command Line Interface or storage management software utilizing the IBM TotalStorage DS Open API.
An external Management Console is available as an optional feature and can be used as a redundant management console for environments with high-availability requirements.
IBM TotalStorage DS Storage Manager: The DS Storage Manager is a single integrated Web-based (HTML) graphical user interface (GUI) that offers:
- Offline configuration: Allows a user to create and save logical configurations and apply them to an online DS8000 series system. This offline configuration tool is installed on a customer server and can be used for the configuration of a DS8000 series system at initial installation or for reconfiguration activities.
- Online configuration: Provides real-time configuration management support.
- Copy services: Allows a user to execute copy services functions.
The online configuration and copy services are available via a Web browser interface installed on the DS management console. The DS Storage Manager is provided with the DS8000 series at no additional charge.
IBM TotalStorage DS Command Line Interface (CLI): The DS CLI is a single CLI that has the ability to perform a full set of commands for both configuration and copy services activities. The application will have three modes of execution:
- Single shot mode will connect, issue a single command, and then return to the user.
- Script mode will connect, execute a predefined customer script, and then return to the user.
- Interactive mode will place the user in a shell environment with a static connection to the storage subsystem so the user can execute multiple commands.
This new CLI has the ability to dynamically invoke copy services functions. This can help enhance your productivity since it eliminates the previous requirement for you to create and save a task using the GUI. The DS CLI can also issue copy services commands to an ESS Model 750, ESS Model 800, or DS6000 series system. The DS CLI is available with the DS8000 series at no additional charge. The DS CLI client is available for the AIX®, HP-UX, Linux, Novell NetWare, Sun Solaris, and Microsoft Windows operating system environments.
IBM TotalStorage DS Open API: The DS Open API supports routine LUN management activities, such as LUN creation, mapping and masking, and the management of point in time copy and remote mirroring. It supports these activities through the use of a standard interface as defined by the Storage Networking Industry Association (SNIA) Storage Management Initiative Specification (SMI-S). The DS Open API is implemented through the IBM TotalStorage Common Information Model Agent (CIM Agent) for the DS Open API, a middleware application designed to provide a CIM-compliant interface. The interface allows Tivoli® and third-party CIM-compliant software management tools to discover, monitor, and control DS8000 series systems. The DS Open API and CIM Agent are provided with the DS8000 series at no additional charge. The CIM Agent is available for the AIX, Linux, and Microsoft Windows operating system environments.
IBM TotalStorage multi-path Subsystem Device Driver (SDD): SDD provides load balancing and enhanced data availability capability in configurations with more than one I/O path between the host server and the DS8000 series system. Load balancing can help reduce or eliminate I/O bottlenecks that occur when many I/O operations are directed to common devices via the same I/O path. SDD also helps eliminate a potential single point of failure by automatically rerouting I/O operations when a path failure occurs, thereby supporting enhanced data availability capability. SDD is provided with the DS8000 series at no additional charge. Fibre Channel (SCSI-FCP) attachment configurations are supported in the AIX, HP-UX, Linux, Microsoft Windows, Novell NetWare, and Sun Solaris environments.

Physical specifications: Refer to the IBM TotalStorage DS8000 Introduction and Planning Guide (GC35-0495). This publication is available at
Licensed Machine Code: The DS8000 series Models 921, 922, 92E, 9A2, and 9AE require Licensed Machine Code (LMC) level 5.0.0, or later.
Some DS8000 series features and functions may not be available or supported in all environments. Current information on supported environments, prerequisites, and minimum operating systems levels is available at
Licensed functions: The following licensed functions are available on the DS8000 series:
Licensed function Description Operating IBM TotalStorage DS Operating environment Environment Point in time copy IBM TotalStorage FlashCopy(R) Remote mirror IBM TotalStorage Metro Mirror and copy IBM TotalStorage Global Mirror IBM TotalStorage Global Copy Remote mirror for IBM TotalStorage z/OS Global z/OS(R) Mirror Parallel access Parallel access volumes volumes
Licensed functions require the selection of a DS8000 series feature number (IBM 2107) and the acquisition of DS8000 Series Function Authorization (IBM 2244) feature numbers:
- The 2107 licensed function indicator feature number enables the technical activation of the function subject to the client applying a feature activation code made available by IBM.
- The 2244 function authorization feature numbers establish the extent of IBM authorization for that function on the 2107 machine for which it was acquired.
IBM 2244 IBM 2107 function Indicator authorization feature models and Licensed function number feature numbers Operating environment 0700 Model OEL 70xx Point in time copy 0720 Model PTC 72xx Remote mirror and copy 0740 Model RMC 74xx Remote mirror for z/OS 0760 Model RMZ 76xx Parallel access volumes 0780 Model PAV 78xx
Refer to Hardware Announcement 104-383 , dated October 12, 2004, IBM TotalStorage DS8000 Series Function Authorizations, for information regarding ordering, authorization levels, and terms and conditions.
Operating environment: An operating environment license is required on every 2107 base unit (Models 921, 922, and 9A2). The extent of IBM authorization acquired through the 2244 Model OEL feature numbers must cover the physical capacity of the 2107 system, where "system" is defined as the base unit and all physically attached expansion units (excluding Standby CoD capacity).
If the operating environment license has not been acquired and activated on the machine, disk drives installed within the 2107 system cannot be logically configured for use. Upon activation of the operating environment, disk drives can be logically configured up to the extent of IBM authorization.
As additional disk drives are installed, the extent of IBM authorization must be increased by acquiring additional 2244 Model OEL feature numbers. Otherwise, the additional disk drives cannot be logically configured for use.
For a 2107 system with Standby CoD disk drives (#2xx7 features), activation (logical configuration) of CoD disk drives may exceed the extent of IBM authorization for the operating environment, in which case an increased authorization level must be acquired.
Remote mirror and copy: To use remote mirror and copy, the remote mirror and copy function authorization (2244 Model RMC) must be purchased for both the primary and secondary 2107.
Remote mirror and copy requires the installation of at least one Fibre Channel/FICON host adapter on each 2107 system in the remote mirror and copy configuration to serve as the remote mirror and copy communications link. For higher availability, IBM recommends that more than one host adapter per system be used for the remote mirror and copy connectivity.
Remote mirror and copy is supported with the use of SAN fabric products, channel extenders, and Dense Wavelength Division Multiplexing (DWDM) products. A current list of supported environments, configurations, network connectivity, and products is available at
Vendors should be consulted regarding hardware and software prerequisites when using their products in a remote mirror and copy configuration. IBM is not responsible for third-party products.
IBM supports the use of remote mirror and copy over the network technologies that are currently supported by the channel extender products, including Fibre Channel, Ethernet/IP, ATM-OC3, and T1/T3. Evaluation, qualification, approval, and support of remote mirror and copy configurations using channel extender products are the sole responsibility of the channel extender vendor. The vendor should be contacted for its distance capability, line quality requirements, as well as SAN and WAN attachment capabilities.
Global Mirror: Global Mirror has the following, additional prerequisites:
- A point in time copy function authorization (2244 Model PTC) must be purchased for the secondary 2107.
- If Global Mirror will be used during failback on the secondary system, a point in time copy function authorization must also be purchased on the primary system.
In the event of a planned or unplanned outage, recovery procedures are required to achieve a consistent and restartable copy of the data at the remote site. Scripts and software can be used to help automate these procedures.
Remote mirror for z/OS: When failback from the secondary 2107 to the primary 2107 is required, the remote mirror for z/OS function authorization (2244 Model RMZ) must be purchased for both systems.
Remote mirror for z/OS is supported with the use of channel extenders and Dense Wavelength Division Multiplexing (DWDM) products. A current list of supported environments, configurations, network connectivity, and products is available at
Vendors should be consulted regarding hardware and software prerequisites when using their products in a DS8000 remote mirror for z/OS configuration. IBM is not responsible for third-party products.
IBM supports the use of remote mirror for z/OS over the network technologies that are currently supported by the channel extender products, including Fibre Channel, Ethernet/IP, ATM-OC3, and T1/T3. Evaluation, qualification, approval, and support of remote mirror for z/OS configurations using channel extender products are the sole responsibility of the channel extender vendor. The vendor should be contacted for its distance capability, line quality requirements, as well as SAN and WAN attachment capabilities.
z/OS Metro/Global Mirror: z/OS Metro/Global Mirror requires the purchase of remote mirror for z/OS and remote mirror and copy.
Remote mirror and copy must be purchased for both the primary and secondary system, and requires the installation of at least one Fibre Channel/FICON host adapter on each DS8000. Refer to the Remote mirror and copy section above for additional information.
Current information on servers, operating systems, host adapters, and connectivity products supported by the DS8000 series is available at
- The 65,520 cylinder 3390 volume is not supported with z/OS Global Mirror and z/OS Metro/Global Mirror.
- The amount of physical capacity within the 2107 system that can be logically configured for use will be enforced by the 2107 Licensed Machine Code to maintain compliance with the extent of IBM authorization established for licensed functions activated on the machine. The 2107 Licensed Machine Code will not allow the logical configuration of physical capacity beyond the extent of IBM authorization (except when activating Standby CoD capacity).
- The deactivation of an activated licensed function, or a lateral change or reduction in the license scope is a disruptive activity and requires a machine IML (Model 921 and Model 922) or reboot of the affected Storage System LPAR (Model 9A2).
The following activities are disruptive:
- Model conversions. In addition, data may not be preserved during the model conversion.
- Field attachment of a Model 92E with the 922 92E Position 1 indicator (#0221) to a Model 922.
- Field attachment of a Model 9AE with the 9A2 9AE Position 1 indicator (#0231) to a Model 9A2.
- Removal of an expansion unit model from the base unit model. Data may not be preserved during this activity.
