HP SureStore E Disk Array
The HP SureStore E Disk Array XP256 and XP512 provides high
capacity and high speed mass storage with continuous data availability,
ease of service, scalability and connectivity. It is designed to handle very
large databases as well as data warehousing and data mining
applications since it has a huge data capacity as measured in terabytes.
It is ideal for clustered configurations of HP-UX servers.
This disk array has no active single point of component failure. It utilizes
component and function redundancy to provide full fault-tolerance for all
microprocessors, control storage, control and data busses, power
supplies, and cooling fans. Thus, it can sustain multiple component
failures and still continue to provide full access to stored data. However,
a failure of a key component can degrade disk array performance.
