ABOUT THE HP SURESTORE E DISK

Your new disk array is a refinement of the successful HP SureStore E Disk

Array XP256 from HP. It provides reliable and secure data protection

The disk array also supports multiple operating systems, platforms, and

RAID groups. The advantages include:

•continuous data availability

•nondisruptive service and upgrades

•connectivity

•scalability

•data integrity

HP SureStore E Disk Array XP512/XP48: Owner’s Guide

Continuous Data Availability

The XP family of disk arrays are the first RAID disk arrays to provide truly

continuous data availability. They are designed for nonstop operation and

continuous access to all user data.

HP XP512 and XP48 disk arrays have no single point of component failure,

which enables uninterrupted access to data.

The disk array has component and function redundancy, providing full fault

tolerance for disk array microprocessors, control storage, control and data

buses, power supplies, and cooling fans. The disk array can sustain multiple

component failures and still continue to provide full access to your stored

data.

While access to your data is never compromised, the failure of a key

component can cause a temporary reduction in disk array performance.
