For ordering, contact: Your IBM representative, an IBM Business Partner, or IBM Americas Call Centers at 800-IBM-CALL (Reference: YE001). OverviewIBM continues to demonstrate commitment to performance with the introduction of 15,000 rpm disk drives for IBM TotalStorage™ Enterprise Storage Server™ (ESS). The 15,000 rpm drives, which are available in 18.2 GB and 36.4 GB capacities, provide new levels of throughput and performance. For a given RAID 5 rank comprised of 36.4 GB 15,000 rpm drives, random read and random write throughput can increase up to 80% compared to 10,000 rpm drives and can help you drive your workloads at significantly higher access densities (without worrying about performance degradation) or achieve significant service time advantages. The ESS is also enhanced with new and expanded Peer-to-Peer Remote Copy (PPRC) solutions and options.
Additionally, many ESS users will benefit from the following support enhancements:
Key PrerequisitesThe following are supported on all ESS models:

DescriptionNew Levels of Throughput and Performance with 15,000 rpm Drives IBM continues to demonstrate commitment to performance with the introduction of 15,000 rpm disk drives for ESS. The 15,000 rpm drives, which are available in 18.2 GB and 36.4 GB capacities, provide new levels of throughput and performance. The new drives are the most recent addition to a long list of performance features offered to ESS customers. For a given RAID 5 rank comprised of 36.4 GB 15,000 rpm drives, both random read and random write throughput can increase up to 80% compared to 10,000 rpm drives! This improvement translates into substantial price/performance benefits for the entire subsystem — an ESS populated with eight RAID 5 ranks of 15,000 rpm drives can provide up to 80% greater total subsystem random throughput for a cache standard workload than an ESS comparably configured with 10,000 rpm drives. This latest enhancement can help you drive your workloads at significantly higher access densities (without worrying about performance degradation) or achieve significant service time advantages. For example, at an access density of 1.0, typical of many customer environments, a service time reduction of up to 25% can be achieved. In more demanding environments, an online transaction processing (OLTP) workload at a relatively stressed access density of 2.5 can enjoy a reduction of up to 40% in service time. These improvements may be even more significant for cache hostile OLTP workloads. Improved service times can lead to shorter batch processing windows or improved productivity because transactions complete more quickly. The new levels of performance and throughput provided by the 15,000 rpm drives can lead to cost savings. For disk-intensive workloads, fewer disk drives may be required to achieve high disk utilization rates. Your IBM disk marketing specialist can help you assess the potential benefits of 15,000 rpm drives in your environment. PPRC Extended Distance (PPRC-XD) Offers New Solutions for Long Distance Data Copy PPRC-XD brings new flexibility to the ESS and PPRC with the introduction of a non-synchronous long distance copy option suitable for data migration, transmission of database logs, and periodic offsite backup. With PPRC-XD, updates are continually transferred to the secondary ESS at the remote site in a non-synchronous mode. This means updates to the ESS primary at the local site are considered complete (for example, ending status is returned to the application) before they are transmitted to the secondary ESS at the remote site. With a non-synchronous operation, the distance between the primary and secondary ESS will have only a minimal effect on the application response time. Therefore, PPRC-XD can operate at very long distances — distances well beyond the 103 km supported with PPRC synchronous transmissions — with the distance typically limited only by the capabilities of the network and channel extension technologies. When operating in PPRC-XD mode, the ESS primary and secondary do not transition to full synchronous mode. This can result in a "fuzzy copy" at the remote site since application-dependent writes are not assured to be applied on the secondary ESS in the same sequence as they were written to the primary ESS. To obtain a consistent copy, PPRC-XD mode can simply be changed to PPRC-SYNC (synchronous mode). Upon reaching full duplex mode (consistency), the PPRC pairs can be temporarily suspended, followed by a FlashCopy on the secondary ESS, and then a resumption of PPRC-XD mode. This operation, which may take tens of seconds or less depending upon the level of I/O activity on the primary, provides a point-in-time consistent copy at the remote site which is suitable for data migration, backup, and disaster recovery purposes. PPRC-XD is provided with the PPRC optional feature on the ESS (#182x). It is managed via a Web interface provided through the IBM TotalStorage ESS Specialist. It is also supported by the ESS Command Line Interface (CLI) in selected open systems environments and by TSO commands in z/OS™ and OS/390®. New PPRC Channel Extension, DWDM, and Network Connectivity Options IBM now supports the use of the following products with PPRC.
PPRC flexibility is further enhanced with support for new network connectivity options when using channel extenders. IBM now also supports the use of PPRC over all the network technologies that are currently supported by the CNT UltraNet Storage Director or the INRANGE 9801 Storage Networking System, including Fibre Channel, Ethernet/IP, ATM-OC3, and T1/T3. These new options support the exploitation of existing or new communication infrastructures and technologies within metropolitan networks and the WAN to help optimize cost, performance, and bandwidth. Fibre Channel/FICON Intermix Support The ESS supports the Fibre Channel/FICON intermix on the INRANGE FC/9000 Fibre Channel Director (IBM 2042 Models 001 and 128) and the McDATA ED-6064 Enterprise Fibre Channel Director (IBM 2032 Model 064). With Fibre Channel/FICON intermix, both FCP (Fibre Channel Protocol) and FICON upper level protocols can be supported within the same director when deployed independently by port. This new operational flexibility can help users to reduce costs with simplified asset management and improved asset utilization. PPRC and FlashCopy Support Extended into the Compaq AlphaServer Environment Support for the ESS PPRC and FlashCopy functions, as well as the new PPRC-XD function, is now available for the Compaq AlphaServer environment running Tru64 UNIX, enabling new business continuance and point-in-time copy solutions. PPRC is a hardware-based disaster recovery solution that provides real-time mirroring of logical volumes within an ESS or to another ESS, which can be located up to 103 km from the primary machine. PPRC is a synchronous copy solution where write operations are made to both copies (primary and secondary) before they are considered to be done. PPRC-XD is a non-synchronous long distance copy solution ideal for data migration, transmission of database logs, and periodic offsite backup. FlashCopy provides a near instantaneous copy of data to help minimize the downtime needed for data backup. FlashCopy creates a physical point-in-time copy of data and makes it possible to immediately access both the source and target copies. By creating an "instant" copy, FlashCopy enables applications using either the source or the target to operate with only a minimal interruption to perform the FlashCopy. PPRC and FlashCopy can be managed via the Web user interface provided through the ESS Specialist or via the CLI. The CLI enables open systems hosts to invoke and manage FlashCopy and PPRC functions through batch processes and scripts. The CLI provides commands to query the status of ESS volumes and to execute Copy Services tasks that were previously saved using the ESS Specialist. By integrating CLI commands into host scripts, FlashCopy and PPRC functions can be integrated into new or existing host automation processes. Planned Availability DatesApril 23, 2002:

Planning InformationPhysical Planning Physical planning information can be found in the IBM TotalStorage Enterprise Storage Server™ Introduction and Planning Guide (GC26-7294). Planning for 15,000 rpm Drives: Your disk marketing specialist can help you plan and anticipate required levels of performance by analyzing your current configuration, utilization and performance, and modeling proposed configurations. The 15,000 rpm disk eight-pack features (#214x/#215x) cannot be intermixed within an ESS with #212x/#213x disk eight-pack features for the same drive capacity.
The 15,000 rpm disk eight-pack features can be intermixed within an ESS as follows:
To install 15,000 rpm disk eight-packs of a given capacity into an ESS which already contains disk eight-packs of the same given capacity (but at 7,200 or 10,000 rpm), those existing disk eight-packs must first be either converted to 15,000 rpm disk eight-packs (of the same capacity) or to disk eight-packs of a different capacity using the disk eight-pack feature conversions. Disk Eight-Pack Feature Conversions Disk eight-pack feature conversions are supported for the following disk eight-pack features:
These feature conversions must be ordered in pairs of the same type. The disk eight-pack feature conversion requires the removal of disk eight-packs from the ESS. Removing logically configured disk eight-packs requires the deconfiguration of all disk eight-packs on the SSA loop (not just the deconfiguration of the eight-packs to be removed). Data contained on the affected SSA loop is not preserved during the deconfiguration. However, data on the remaining SSA loops is not affected and can continue to be accessed. The customer is responsible for making a copy of the data contained on the affected SSA loops prior to the deconfiguration and restoring the data after the installation of the new disk eight-packs has been completed. IBM is not responsible for any data contained on the returned disk eight-packs. As required by customer policies and practices, the customer is responsible for erasing and/or invaliding data on disk eight-packs before they are removed from the ESS by IBM service personnel. The logical configuration of the new disk eight-packs is a customer responsibility. The additional capacity provided by the new disk eight-packs may require the need to purchase an advanced function license upgrade for Parallel Access Volumes (PAV), Extended Remote Copy (XRC), PPRC, and FlashCopy. The installation of a license upgrade is a concurrent action. The additional capacity may also require an increase in the maximum number of logical subsystems (LSS) that can be configured. This modification to increase the maximum is a non-concurrent action. Refer to the IBM TotalStorage Enterprise Storage Server Introduction and Planning Guide (GC26-7294) for additional information. PPRC Extended Distance (PPRC-XD) The implementation and use of PPRC-XD requires appropriate planning. Detailed information can be found in the following IBM Redbook:
Implementation and planning services for PPRC-XD are also offered by IBM Global Services (IGS). For additional information, contact your IBM representative or visit: PPRC-XD is provided with the PPRC licensed feature (#182x). The license must be equal to or greater than the total capacity of the ESS. When purchasing a license for a Step Ahead configuration (Model F20 only), the license must be equal to or greater than the total capacity of the machine (including the Step Ahead capacity). The PPRC license must be purchased for both the primary and secondary ESS. If FlashCopy will be used in conjunction with PPRC-XD, the FlashCopy licensed feature (#183x) must also be purchased for each ESS on which it will be used. PPRC (and PPRC-XD) requires the installation of at least one ESCON Host Adapter (#3011 or #3012) on each ESS to provide the communications link between the ESS primary and ESS secondary server. For highest availability, IBM recommends that more than one ESCON adapter per ESS be used for the PPRC connectivity. PPRC (and PPRC-XD) is supported with the use of ESCON Directors, DWDMs, and channel extenders. A complete and current list of supported environments, configurations, networks, and products is available at: When using channel extender products with PPRC, the channel extender vendor will determine the maximum distance supported between the primary and secondary ESS. CNT and INRANGE should be contacted for their distance capability, line quality requirements, and WAN attachment capabilities. New PPRC Channel Extension, DWDM, and Network Connectivity Options PPRC is supported with the use of ESCON Directors, DWDMs, and channel extenders. A complete and current list of supported environments, configurations, networks, and products is available at: Evaluation, qualification, approval, and support of PPRC configurations using channel extender products is the sole responsibility of the channel extender vendor. CNT and INRANGE should be contacted for their distance capability, line quality requirements, and WAN attachment capabilities. When using PPRC as a synchronous copy solution, prior approval must be received from IBM if the distance between the primary and secondary ESS will exceed 103 km. Approval can be requested by submitting a Request for Price Quotation (RPQ). The RPQ should include information on distance between sites, the channel extension technology, the type of telecom line, the amount of network bandwidth, the ESS capacity, and a general description of the workload. Fibre Channel/FICON Intermix Support Implementation details and operational information for using intermix with the INRANGE FC/9000 Director is available at: For implementation details and operational information for using intermix with the McDATA ED-6064 Director, review the FICON/FCP Intermix white paper that is available at: PPRC and FlashCopy for the Compaq AlphaServer Environment The implementation and use of PPRC and FlashCopy require appropriate planning. Detailed information can be found in ESS publications and IBM Redbooks™. Implementation and planning services for PPRC and FlashCopy are also offered by IBM Global Services (IGS). For additional information, contact your IBM representative or visit: PPRC and FlashCopy are licensed features (#182x for PPRC and #183x for FlashCopy).
