Space-efficient Way to Rack-mount Tape Drives and RDX Backup Systems. HP Rack-mount Kits are ideal for customers who have limited space in their rack as it allows for a smaller footprint leaving valuable space for other key components in the data center. The 1U rack enclosure can hold up to (2) half-height drives. The 3U rack enclosure can hold (2) full-height drives, (4) half-height drives, or (1) full and (2) half-height drives. The 1U and 3U Rack-mount Kits allow users to mix a variety of tape technologies, including DAT and Ultrium, as well as RDX removable disk technology. The enclosures support standard internal tape drives and RDX removable disk backup systems, allowing for drive upgrades when you need additional capacity or want to migrate to new generation of tape drives or RDX removable disk technology. SCSI, SAS and USB Interfaces to Suit your Environment. - SCSI versions of the 1U and 3U Rack-mount Kit allow customers to connect SCSI tape drives to high-density servers where rack space is a premium. SAS versions of the 1U and 3U Rack-mount Kit allow customers to rack-mount SAS-based tape drives providing an alternative to internal models in racked environments. The 1U USB Rack-mount Kit is an industry first for enclosures; this solution will allow customers alternative methods to connecting HP USB tape drives to servers, in addition to internal and table top models.
