storeonce - backup, recovery

storall - archive, object & file storage

storeserv - primary storage

Though with the new file persona, HP 3PAR StoreServ now also supports file and object.  Here are URLs to each of those product families:

• HP StoreOnce: www.hp.com/go/StoreOnce
• HP StoreAll: www.hp.com/go/StoreAll
