Earlier this month, Hewlett-Packard added to its high-end XP disk array line when it started shipping the HP SureStore e XP512 array, which provides heterogeneous storage and server consolidation and a link between legacy mainframes and open systems.
For example, with added operating system support for Solaris, HP officials anticipate the array will be used to help consolidate Solaris and Windows NT servers. The XP512, based on technology from Hitachi's Freedom arrays, has an increased capacity of 24TB with Hitachi 47GB disk drives. In the Fall, when Hitachi ships 73GB, 10,000rpm drives, XP512 capacity will reach 40TB.
HP officials believe the array's most significant innovation is replacing the bus-based architecture of the earlier-generation XP256 with a new crossbar switch, which provides 6.4GBps throughput (see diagram).
HP's XP512 is based on a 6.4GBps crossbar switch that replaces the bus-based architecture of the XP256.
HP has also made its array backplane completely Fibre Channel, and doubled the port total to 32, which can be mixed between Fibre Channel and Escon. Up to 32 Fibre Channel connections are supported. HP also doubled the array's memory cache to 32GB.
On the software side, the XP512 is available with enhanced CommandView XP storage management software, which now integrates with HP's OpenView network management suite. And management information base (MIB) support now allows communications with other vendors' management frameworks.
A base 200GB XP512 configuration starts at $250,000.
