controller
(1) A hardware–software device that manages communications on behalf of
host systems over the SCSI bus to devices. Controllers typically differ by
the type of interface to the host and provide functions beyond those the
devices support. (2) A standalone device that connects a host adapter to the
storage SCSI bus. This device provides RAID functionality, typically has
multiple SCSI bus ports, performs the lower layers of the SCSI protocol,
and normally operates in the initiator role.
Also referred to as array control or SCSI bus controller.
