2 HP XP10000 hardware components

There are no single points of failure in HP XP10000 disk arrays. Redundant logic assemblies,
controllers, disk drives, and power supplies can be removed or replaced without interrupting access
to data. This section describes individual physical components of the disk array. See
page 13 for an overview of the disk array hardware.
CAUTION:
Only your HP support representative can remove or replace hardware.

Disk controller

The disk controller is part of the basic disk array configuration housed in the primary rack and controls
disk array operation. It contains the control panel, connection hardware, power supplies, SVP, and
control boards for the disk array.

Service processor (SVP)

The Service Processor inside the controller performs these functions:
• Collects performance data on the system for diagnostic testing and analysis
• Provides your HP support representative with access to the system
• Hosts system management software
HP support representatives use the SVP to configure, maintain, and upgrade the system software and
hardware. The SVP is not a customer-accessible component.
To protect your security, the SVP does not have access to any user data stored on array disks.
If you have extreme availability requirements, an optional second SVP is available.

Control panel

Once the disk array is powered on and running normally, no user operations are required at the
control panel, except when instructed by your HP support representative.
Figure 2 and Table 3 describe the control panel.
