HP 4400 Enterprise Virtual Array Expansion Rack Reference Guide (5697-2285, January 2013)

1 Getting started

First, decide what type of expansion you will perform; this will determine which hardware

components are needed.

• EVA4400 components—The EVA4400 can support a maximum of 8 disk enclosures (main

and expansion racks combined). If the main rack containing the EVA4400 includes non-EVA

components (such as servers or switches) is full, you can add an expansion rack.

• EVA4400 2C8D main rack—The main rack is full with 2 controllers and 8 disk enclosures. If

there is insufficient space to put all 8 disk enclosures in the main rack, disk enclosures can be

added in an expansion rack.

• EVA4400 0C7D expansion rack

The expansion rack can contain up to 7 disk enclosures. To add disk enclosures to the main

rack of an EVA4400, see the HP 4400 Enterprise Virtual Array Installation Guide. The

installation guide contains cabling diagrams for various configurations. This document shows

how to add disk enclosures in an expansion rack to an existing configuration.

Hardware requirements

The following table lists the components needed to expand EVA4400 configurations.

Expansion rack requirements

• One existing main rack containing a properly wired controller pair and disk enclosures (see

Figure 1 (page 5)). The main rack can contain up to 2C8D controllers and disk enclosures.

The controllers may be above or in the middle of the disk enclosures, depending on the number

of disk enclosures and how the rack was initially configured. Figure 1 (page 5) is an example

only, a 2C4D configuration.

• The main rack must be running properly.

• A new expansion rack containing up to 7 properly wired disk enclosures. Figure 2 (page 5)

is an example only, showing two disk enclosures and assuming there are up to six disk

enclosures in the main rack.
