Continuous data availability
The HP StorageWorks Disk Array XP 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.
The following features ensure continuous data availability:
• No single point of component failure, which enables uninterrupted access to data
• Component and function redundancy, providing full fault tolerance for disk array
microprocessors, control storage, cache, control and data buses, power supplies,
and cooling fans
• Can sustain multiple component failures and still continue to provide full access
to stored data
Note that although access to data is not compromised, the failure of a key component
can cause a temporary reduction in disk array performance.
