DS8300 overview

The DS8300 Models 932 and 9B2 offer higher storage capacity than the DS8100, and they provide greater throughput by means of their dual four-way processor implementation.

Figure 1 provides a high-level view of the components of a base model (Models 922, 932, 9A2, and 9B2).

The following notes provide additional information about the labeled components in Figure 1.
  1. The rack power area of the base models provides redundant power supplies (two primary power supplies), power control cards, and backup battery assemblies to help protect data in the event of a loss of external power. Models 921, 931 contain two batteries. Models 922, 932, 9A2, 9B2 contain three batteries to support the 4-way processors.
  2. All base models can have up to eight disk enclosures, which contain the disk drives. In a maximum configuration, each base model can hold up to 128 disk drives.
  3. All base models contain one management console comprised of a keyboard and display or laptop. The management console is the focal point for configuration, Copy Services management, and maintenance activities. The Tivoli Storage Productivity Center is the focal point for configuration, Copy Services management, and maintenance activities where it is in use.
  4. All base models contain two processor enclosures. Models 921 and 931 processor enclosures have 2-way processors. Processor enclosures on Models 922, 932, 9A2, 9B2, and have 4-way processors.
  5. All base models contain I/O enclosures and adapters. The I/O enclosures hold the adapters and provide connectivity between the adapters and the processors. Both device adapters and host adapters are installed in the I/O enclosure.
Note: Models 921, 922, and 9A2 apply only to hardware machine type 2107. These models have been withdrawn from marketing. Although you can no longer order these hardware models directly from IBM, you can order add-on features or licensed functions for your existing 2107 hardware models. You can obtain the hardware models on an as-available basis through IBM Business Partners.

Figure 2 provides a high-level view of the components of an expansion model (Models 92E, 9AE).

The following notes provide additional information about the labeled components in Figure 2:
  1. The rack power area of each expansion model provides redundant power supplies (two primary power supplies) and power control cards. If the expansion model contains I/O enclosures or the extended power line disturbance (PLD) feature, two or three backup battery assemblies are also installed to help protect data in the event of a loss of external power.
  2. All expansion models can have up to 16 disk enclosures, which contain the disk drives. In a maximum configuration, each expansion model can hold 256 disk drives.
  3. Expansion models can contain I/O enclosures and adapters if they are the first expansion models that are attached to a Model 922, 932, 9A2, 9B2. The second, third, or fourth expansion model in a 922, 932, 9A2, or 9B2 configuration cannot have I/O enclosures and adapters, nor can any expansion model that is attached to a Model 921 or 931. If the expansion model contains I/O enclosures, the enclosures provide connectivity between the adapters and the processors. The adapters contained in the I/O enclosures can be either device or host adapters.
DS8000 expansion models (Models 92E , 9AE) can be attached to a base model to expand its capabilities:
