Chapter 1. Introduction to IBM TotalStorage DS8000 series
IBM TotalStorage DS8000 is a high-performance, high-capacity series of disk
storage that is designed to support continuous operations. DS8000 series models
(machine type 2107) 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. 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.

DS8000 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 (Model 921) features a dual two-way processor complex and
support for one expansion frame.
DS8300
The DS8300 (Models 922 and 9A2) features a dual four-way processor
complex and support for one or two expansion frames. The Model 9A2
supports two IBM TotalStorage System LPARs (Logical Partitions) in one
storage unit.
The DS8000 expansion frames (Models 92E and 9AE) expand the capabilities of
the base models. You can attach the Model 92E to either the Model 921 or the
Model 922 to expand their capabilities. You can attach the Model 9AE to expand
the Model 9A2.
Figure 1 on page 2 provides a high-level view at the components for the DS8100
and DS8300 base models (Models 921, 922, and 9A2).
