Tape Drives
The library supports Ultrium160 SCSI, Serial Attached SCSI (SAS), and Fibre
Channel tape drives.
Tape drives (1 in Figure 2-2 on page 2-5) are hot addable (library power remains
ON and operations of the installed tape drives are still active). Drives can be
removed and installed without tools.
Ultrium160 SCSI tape drives are attached directly to a host. Fibre Channel tape
drives can be directly attached to a host or a Storage Area Network (SAN). Each
SAS link is point-to-point so a maximum of 2 hosts could share a dual-port SAS
tape drive.
Drives mounted in sleds are installed into tape drive slots in the rear of the library.
If a tape drive slot is empty, a metal plate covers the empty drive slot. This "metal
plate" cover has a connector that plugs into the drive connector, providing
electrical termination for some of the drive circuits. It also serves as a safety cover,
and prevents debris from entering the library. All empty drive slots must have one
of these covers installed for proper library operation.
