Continuous Data Availability - HP StorageWorks XP10000 Owner's Manual

Continuous data availability

Note:
12
The HP StorageWorks Disk Array XP family is among 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.
The following XP10000 features ensure continuous data availability:
• No single point of component failure, which enables uninterrupted
access to data
• Component and function redundancy, providing fault tolerance for
disk array microprocessors, control storage, cache, control and data
buses, power supplies, and cooling fans
Although access to data is not compromised, the failure of a key component
can cause a temporary reduction in disk array performance.
