ABOUT THE HP SURESTORE E DISK

ARRAY XP512 AND XP48

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 featuring redundant circuitry and RAID storage options for data security. 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

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 dis k arrays have no s ingle point of comp onent fai lure, which enables uninterrupted access to data.

The disk array h as component and func tion red undancy, providing ful l fault tolerance for disk array microprocessors, control storage, control and data buses, power suppli es, and cooling fans . The disk array c an sustain mult iple 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.

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

Nondisruptive Service and Upgrades

Monitoring software detects failed disk drives or internal hardware and notifies the HP Stress Free Central support center automatically so an HP service representative can replace the faulty hardware. There is no need to be concerned with user serviceable components. Only an HP Service Representative should open the cabinets.

All hardware subassemblies can be removed, serviced, repaired, or replaced nondisruptively during disk array operation. All microcode upgrades can be performed dur ing normal dis k array opera tions, usin g your disk array’s built-in service processor (SVP) or the facilities of the host. Alternate paths can be set by host failover software or alternate Fibre Channel paths.
