Smart Array Internal Cabling Guide

Chapter 3

3 Cabling for the Server Expansion Unit

This chapter describes how to connect the cables of an HP Smart Array controller card to the internal hard

drives of a Server or Server Expansion Unit (SEU) connected to an HP Integrity rx8620 or rx8640 server.

NOTE These instructions do not apply if you are connecting the controller card to an external mass

storage box. Refer instead to the HP Smart Array Controller User Guide that shipped with your

card.

Table 3-1 shows the product numbers, descriptions and support matrix for the HP Smart Array controllers

supported on the rx8620 and rx8640 servers. If a card is supported in a server, that card is also supported in a

SEU connected to that server.

NOTE When cabling an HP Smart Array controller card to the Server Expansion Unit (SEU), the

PCI-X I/O and SCSI HDD Backplane architecture are identical in the rx8620/rx8640 server

and in the Server Expansion Unit. Adding the Server Expansion Unit allows for a 3-partition

or 4-partition configuration.

Before you begin, you need:

• Cable kit (part number: A7027-63001)

• Smart Array controller card: See Table 3-1 for product numbers.

NOTE The part and product numbers listed in this document are correct as of the release date of the
