Ultrium Tape Drives
This library supports the Ultrium 3, Ultrium 4, and Ultrium 5 Tape Drives. Each
tape drive in the library is packaged in a container called a drive sled. The drive
sled is a customer replaceable unit (CRU), and is designed for quick removal and
replacement in the library.
The Ultrium 5 Tape Drive supports two SAS SFF-8088 connectors, or one LC Fibre
Channel connector. The SFF-8088 SAS connectors on the Ultrium 5 tape drives are
compatible with SAS-1 or SAS-2 cables.
