Model Abstract 2105-750
The ESS Model 750 is a new model in the family of Enterprise Storage Servers. It provides an entry point into the ESS product family comprised of the ESS Model 750 and the ESS Model 800. The ESS Model 750 offers many of the features of the ESS Model 800, but is based on dual two-way processors with up to 16 GB cache and 2 GB of NVS in contrast to the dual four or six-way processors available with the ESS Model 800. With support for up to 4.6 TB of physical capacity and eight 2Gb Fibre Channel/FICON or ESCON host adapters, the ESS Model 750 is designed to provide an attractive price/performance balance for clients requiring smaller configurations. The ESS Model 750 is well-suited for environments where the workload access densities average two operations per second per gigabyte.

The ESS Model 750 supports FlashCopy and FlashCopy Version 2, as well as PPRC and PPRC Version 2, for point-in-time copy options and advanced metropolitan or long-distance business continuance solutions. The ESS Model 750 also includes support for zSeries performance enhancers; PAV, priority I/O queuing, and multiple allegiance. Additionally, the ESS Model 750 is upgradable to the ESS Model 800, offering clients' investment protection and full ESS scalability.

Model Abstract 2105-800
The IBM 2105 TotalStorage Enterprise Storage Server (ESS) Model 800, the third generation of IBM intelligent storage, sets yet another milestone in ESS functionality, flexibility, performance, and overall value available to meet today's storage requirements. As demands for data increase, so must storage capacity, and accessibility from heterogeneous server environments. As business transaction volumes increase, storage throughput and response time must scale to meet increasingly demanding quality of service agreements. As SANs migrate to 2 Gigabit (2Gb) technology, storage should be able to exploit this bandwidth. As faster disk drive technology, spinning at 15,000 rpm, and combinations of RAID technology are brought to the marketplace, storage administrators need to be able to configure solutions that best meet business needs. The ESS Model 800 is designed to address all these requirements while helping to protect investments you have already made in servers, SANs, software, storage hardware, and advanced functions. The Model 800 is designed to provide performance, scalability, and flexibility while supporting 24 x 7 operations to help provide the access and protection demanded by today's business environment, and delivering the flexibility and centralized management needed to lower long-term costs.

The Model 800 integrates a new generation of hardware, including faster symmetrical multi-processors (SMP) with an optional Turbo feature, 64 GB cache, double internal bandwidth, and 2Gb Fibre Channel/FICON Host Adapters. This hardware, in addition to RAID 10 support and 15,000 rpm drives, enables the Model 800 to deliver excellent levels of performance and throughput.

The ESS is IBM's premier storage solution for use in Storage Area Networks (SANs). It provides:

• Support for the intermix of FICON (F10, F20), ESCON, Fibre Channel and SCSI attachments, making the ESS a natural fit for storage and server consolidation requirements.
• Concurrent support for all your major server platforms, including OS/390, OS/400, Windows NT, Windows 2000, NetWare, and many varieties of UNIX.
• Disk drive capacity intermix support providing extensive flexibility with a vast number of configuration options so price, performance, and capacity can be optimized to meet specific server and applications requirements -- all within a single ESS.
• Excellent scalability from 420 GB to over 1.6 TB (E10), 11.2 TB (E20), 3.3 TB (F10), 22.4 TB (F20) of RAID-5 effective capacity.
• Extensive storage management capabilities, including:
  • FlashCopy for fast data duplication
  • Advanced Remote Copy Services for your synchronous and asynchronous backup and disaster recovery needs
  • Extensive StorWatch(TM) management capability through the Web
  • ESS API to easily manage multiple storage devices (on select models)
• Superior performance with options and innovations to meet your changing requirements
• High availability to support your e-business and other mission-critical applications

Model Summary Matrix

Note: (1) The RAID-5 effective capacity represents an approximation of the total capacity that is usable for customer data when the ESS disk eight-packs are configured as RAID-5 arrays. All available capacity may not get fully utilized due to overheads on logical devices and/or a loss of capacity due to a configured set of logical devices.

Model Conversions

Note: (1) Feature #4002, #4004, or #4006 must be selected when upgrading Model E10 to Model F10 or Model E20 to Model F20.
Note: (2) Parts removed or replaced become the property of IBM and must be returned.
Note: (3) When ordering the model conversion, the Standard Processor feature (#3604) must be selected. Additionally, if the ESS Model 750 has only two disk eight-pack features (#212x), a minimum of two additional disk eight-pack features must be ordered
