The HP StorageWorks family of Ultrium tape drives is HP's premier line of tape backup devices. Based on LTO Ultrium format, an open standard with a well-defined six-generation roadmap, HP Ultrium tape drives offer customers the best choice for investment protection relative to their backup and archival requirements. HP pioneered the half-height Ultrium drive, as the only manufacturer offering full-height and half-height models of each generation of Ultrium drives. Delivering the perfect balance of capacity and performance, HP Ultrium half-height drives are designed for server customers in direct attached storage (DAS) environments where hard disk and system bottlenecks can impede data transfer rates. Four generations of half-height drives are available from HP, offering a wide portfolio to meet the backup requirements for entry and midrange servers.
