IBM DS8000 - ADDITIONAL INFORMATION, User Manual, Page: 29 / 250

Chapter 1. Introduction to IBM System Storage DS8000 series
IBM System Storage DS8000 series is a high-performance, high-capacity series of
disk storage that is designed to support continuous operations. DS8000 series
models (machine type 2107/242x) use the IBM POWER5
™
server technology that is
integrated with the IBM Virtualization Engine
™
technology. DS8000 series models
consist of a storage unit and one or two management consoles, two being the
recommended configuration. You can attach a maximum of four DS8000 series
models to each management console. The graphical user interface (GUI) or the
command-line interface (CLI) allows you to logically partition storage and use the
built-in Copy Services functions. For high-availability, hardware components are
redundant.
You can read the information in this section to familiarize yourself with the DS8000
series.
You can also view the DS8000 series e-learning overview from the DS8000 Storage
Manager Welcome page or at the following Web site:

The e-learning overview provides an animated presentation about installation and
configuration, service and support, and management tasks.
Overview of the DS8000 series models
The DS8000 series offers various choices of base and expansion models, so you can
configure storage units that meet your performance and configuration needs.
DS8100
The DS8100 (Models 921 and 931) features a dual two-way processor
complex and support for one expansion model.
DS8300
The DS8300 (Models 922, 932, 9A2, and 9B2) features a dual four-way
processor complex and support for up to four expansion models. Models
9A2 and 9B2 support two IBM System Storage System logical partitions
(LPARs) in one storage unit.
DS8000 expansion models (Models 92E, 9AE) can be attached to a base model to
expand its capabilities:
921 and 931 (base) can attach to 92E (expansion)
922 and 932 (base) can attach to 92E (expansion)
9A2 and 9B2 (base) can attach to 9AE (expansion)
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models have been withdrawn from marketing.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.
