Serial

SCSI
(SAS)
Requirements
Serial Attached SCSI (SAS) is a computer bus technology mainly used to transfer data to and from
storage devices, including disk drives and tape drives. SAS is designed to transfer data at up to
6 gigabits per second.
SAS uses serial connections, with a direct connection between the host server and each of the storage
devices. This eliminates the need to configure SCSI buses and assign SCSI IDs, as was required for
parallel SCSI devices.
Most SAS host bus adapters (HBA) ports have four SAS channels. A tape drive uses one channel, so
each HBA port can support up to four tape drives via a fan‐out cable. You can use a cable with one
connector on each end, but only one channel will be used.
NOTE
The
library
has
a
mini
‐
SAS
connector
on
each
SAS
tape
drive.
Mini
