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.
