Tape Drives

The T950V supports LTO‐6 and later generation Fibre Channel full‐height
drives, LTO‐7 and LTO‐8 half‐height Fibre Channel and SAS drives in full‐
height drives sleds, and TS1150 technology and higher drives. The drives
are mounted in drive sleds, which are installed in DBAs in the main and
drive expansion frames. Each DBA can accommodate up to four drives.
Drives are hot‐swappable to provide uninterrupted operation.

Description
The drive sled provides the electrical and logical connections to the library,
as well as the connections to the host Fibre Channel arbitrated loop or fabric.
The drive sled firmware assigns an identifier to the drive based on its location
in the library (see Drive Identifiers on page 58). This identifier is used by the
library to identify the drives in the BlueScale and XML interfaces.
See Drive Connectivity on page 65 for additional information about the
Fibre Channel connectivity provided by the drive sled.
Each Fibre Channel drive sled has two multi‐mode optical SFP LC
connectors (Port A and Port B) that are used to connect the drive directly to
a Fibre Channel network. The two ports let you connect two separate fiber
optic cables to each drive.
For half‐height drives in a full‐height sled, only port A is available.
Note:
Each SAS drive sled has a single, unshielded, SFF‐8088 serial port that
provides the Serial Attached SCSI (SAS) connectivity for the drive.
