The HP StorageWorks Rack-Mount Kits provide a high-density, rack-mountable tape drive enclosure for direct-attach SCSI backup and archiving applications. Because these enclosures use standard internal tape drives, they provide a cost-effective means of mounting tape drives in rack server environments. These enclosures provide customers with scalability, allowing the customer to add drives and migrate to new tape technologies as their capacity and performance needs grow.The 1U Rack-Mount Kit meets all RoHS compliance requirements and is available in both SCSI and USB interfaces. Both offerings hold up to two half-height internal tape drives.
