An acronym for “Small Computer System Interface”, SCSI is an industry-standard

A bus that complies with the SCSI standard. The six channel that connect the disk array
controller system to the disk systems are SCSI 2 busses. Each disk system has two
internal SCSI-2 busses that can be configured as independent busses that connect five
disk slots to each BCC controller. or as a single internal bus.
SCSI ID
A unique number assigned to each device connected to a SCSI bus. This number is used
by the HBA to address each device on the bus. Each disk in a disk system is assigned a
SCSI ID of 0 - 9.
