2 HP XP12000 hardware components

There are no single points of failure in the disk arrays. They include redundant logic assemblies,

controllers, disk drives, and power supplies, all of which can be removed or replaced without

interrupting access to data. This chapter describes the physical components of the disk array.

CAUTION:

Only your HP support representative can remove or replace hardware.

Hardware overview

The disk array includes the following major hardware components:

• One disk control frame (DKC)

• Zero to four disk array frames (DKUs)

• One service processor (SVP)

A Command View XP Advanced Edition Device Manager server for monitoring and managing the

disk array is optional.

Figure 1 shows the disk array with the maximum of four DKUs. The DKC alone constitutes the minimum

configuration.
