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.
