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 supports continuous operations.
The DS8000 series includes the DS8800 (Models 951 and 95E) and the DS8700
(Models 941 and 94E). The DS8700 uses IBM POWER6
®
server technology, which
represents a level of high-performance and high-capacity for disk systems. The
DS8700 also provides improved performance through upgrades to processor and
I/O enclosure interconnection technology.
The latest and most advanced disk enterprise storage system in the DS8000 series
is the IBM System Storage DS8800. It represents the latest in the series of
high-performance and high-capacity disk storage systems. The DS8800 supports
IBM POWER6+ processor technology to help support higher performance.
The DS8000 series including the DS8800 and DS8700 support functions such as
point-in-time copy functions with IBM FlashCopy, FlashCopy Space Efficient, and
Remote Mirror and Copy functions with Metro Mirror, Global Copy, Global Mirror,
Metro/Global Mirror, IBM z/OS
®
Global Mirror, and z/OS Metro/Global Mirror.
Easy Tier functions are supported on DS8800 and DS8700 storage units.
All 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) provide the ability to logically partition
storage and use the built-in Copy Services functions. For high-availability, the
hardware components are redundant.
The Tivoli Key Lifecycle Manager (TKLM) software performs key management
tasks for IBM encryption-enabled hardware, such as the DS8000 series by
providing, protecting, storing, and maintaining encryption keys that are used to
encrypt information being written to, and decrypt information being read from,
encryption-enabled disks. TKLM operates on a variety of operating systems.
To learn additional information about the DS8000 series, you can view the
e-Learning modules that are available from the IBM System Storage DS8000
Storage Manager Welcome page or the IBM System Storage DS8000 Information
Center. The e-Learning modules provide animated presentations that describe the
installation, configuration, management, and servicing of the DS8000 series.
DS8700 overview
The DS8700 series offers various choices of base and expansion models, so you can
configure storage units that meet your performance and configuration needs.
The DS8700 (Model 941) provides the option of a dual two-way processor complex
(feature code 4301) or dual-four way processor complex (feature code 4302). A dual
four-way processor complex provides support for up to four expansion models
(94E). (Dual LPAR support is not available for the DS8700.)
Figure 1 on page 2 provides a high-level view of the components of Model 941
(2-way processor).
