HP XP
The HP Storageworks XP is an enterprise storage disk array sold by Hewlett-Packard using Hitachi hardware and adding their own software to it.[1] It is similar to the Hitachi Lightning and Sun StorEdge 9900 and targeted towards enabling large scale consolidation, large database, Oracle, SAP, Exchange, and online transaction processing (OLTP) environments.
The P9000 XP Disk Array family
HP chose to change the name of the XP family to the P9000 XP, to match with other disk array products they sold at the time (P2000, P4000, P6000 and P10000).
