1 Overview of the HP XP10000 Disk Array

This disk array is part of the HP StorageWorks XP Disk Array series of high-performance RAID-capable
disk array systems used to store large quantities of data in an efficient and secure manner. XP disk
arrays support multiple operating systems, platforms, and RAID groups. Advantages include:
•

Continuous data availability

•

Non-disruptive service and upgrades

• Connectivity
• Scalability
• Data integrity and high availability
Continuous data availability
The HP StorageWorks XP Disk Array family includes the first RAID disk arrays to provide truly continuous
data availability. XP disk arrays are designed for nonstop operation and continuous access to all user
data.
Continuous data availability features include:
• No single point of component failure
• Component and function redundancy for disk array microprocessors, control storage, cache,
control and data buses, power supplies, and cooling fans
Although the failure of a key component can cause a temporary reduction in performance, the disk
array can sustain multiple component failures and still continue to provide full access to stored data.
Non-disruptive service and upgrades
Without disrupting normal disk array operations (if alternate pathing is used), an HP support
representative can:
• Remove, service, repair, or replace hardware subassemblies
• Use the built-in service processor (SVP) to upgrade microcode
Alternate paths can be established using host failover software, alternate Fibre Channel paths, nonstop
SCSI, or combination solutions.
CAUTION:
The disk array has no user-serviceable components. The SVP does not include a keyboard or monitor and
is not a customer-accessible component. Only an HP support representative should open the disk array
cabinets.
HP StorageWorks XP Continuous Track monitoring software detects internal hardware component
problems and automatically reports them to the HP Storage Technology Center (STC) before they are
noticed by operators and users. An HP support representative can verify the problem and perform
