Unit emergency power off switch

The UNIT EMERGENCY POWER OFF switch is located on the back of the DKC cabinet.
For more information about this switch, see

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
Your HP support representative uses 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.

Disk drives

The DKC must contain at least nine hard disk drives and can contain up to 128. For more
information about disk drives, see the following section about disk drives in the DKUs.

HP StorageWorks Continuous Track XP

HP Continuous Track XP is a program in the system that detects and reports problems
even before they are noticed by operators and users. HP Continuous Track XP "phones
home" to the HP Storage Technology Center (STC), providing:
• Periodic "well" checkups
This checkup records the health of the disk array on a day-to-day basis. Every
24 hours, HP Continuous Track XP calls STC (your HP support representative sets
the time of the call). When a successful connection is made, status information is
transferred from the disk array to STC. If any configuration changes have been made,
configuration information is also sent.
• Incidental "sick" calls
When an error occurs, a service information message (SIM) is generated, stored in
the disk array for use by your HP support representative, and reported to STC. For
more information, see
Note that the "phone home" capability can be turned off, if desired. HP Continuous Track
XP still monitors the disk array, but does not automatically notify HP if a problem occurs.
