v Chapter 3, the section Upgrading the DS Storage Manager on Linux, in silent

mode was added to show the steps for upgrading the DS Storage Manager.

v Chapter 8, the section FlashCopy information was added to explain how to set

up a Remote FlashCopy operation, which allows a source volume of a remote mirror and copy volume pair on a source (local) storage unit to be sent across paths (acting as a conduit) to a target storage unit to enable a FlashCopy pair to be established at the target site. This eliminates the need for a network connection to the target site solely for the management of FlashCopy.

xxiv DS8000 User’s Guide

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.

You can read the following information to familiarize yourself with the DS8000 series:

v DS8000 series models, including a model comparison chart

v DS8000 series performance features

v DS8000 series interfaces

v DS8000 series hardware specifics

v Supported systems for open systems, S/390®, and zSeries

hosts

v Data management elements

v Copy Services

v Data migration

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).

The following notes provide additional information about the labeled components on 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. Model 921 contains two batteries. Model 922 and Model 9A2 contain three batteries to support the 4-way processors.

2. All base models allow 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 (MC), a keyboard, and display. The Management Console is the focal point for configuration, copy services management, and maintenance activities.

4. All base models contain two processor enclosures. The processor enclosures contain the computer electronic complex (CEC). The Model 921 processor enclosures have 2-way processors. Processor enclosures on the Model 922 and Model 9A2 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.

models (Models 92E and 9AE).

The following notes provide additional information about the labeled components on 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 unit contains I/O enclosures or the extended power line disturbance (PLD) feature, three backup battery assemblies are also installed to help protect data in the event of a loss of external power.

2. All expansion models allow 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 units that are attached to either a Model 922 or a Model 9A2. The second expansion model in a 922 or 9A2 configuration cannot have I/O enclosures and adapters, nor can any expansion unit that is attached to a Model 921. If the expansion unit 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.

DS8100 (Model 921)

The IBM TotalStorage DS8100, which is Model 921, offers many features.

These features include:

v Dual two-way processor complex

v Up to 128 disk drives, for a maximum capacity of 38.4 TB

v Up to 128 GB of processor memory (cache)

v Up to 16 fibre-channel/FICON or ESCON

host adapters

The DS8100 model can support one expansion frame. With one expansion frame, you can expand the capacity of the Model 921 as follows:

v Up to 384 disk drives, for a maximum capacity of 115.2 TB

Note: IBM service representatives can upgrade a Model 921 in the field when you

order a model conversion to a Model 922 or Model 9A2.

Figure 3 shows the maximum configuration of a Model 921, which is the 921 base model plus one 92E expansion model.
