Cine Disk Backplanes
Each Cine Disk Backplane performs several functions:
• Provides power to each disk drive
• Provides looping input and output FC-AL fibre channel connectors
• Provides loop resiliency circuits (LRCs) that detect whether drives are plugged in and route the FC-AL signal past
missing or inoperative drives
Cine Hard Disk Drives
The Cine Disk drives are much like standard SCSI drives, except that they contain circuitry that unpacketizes incoming
commands and data into normal SCSI format, and packetizes outgoing SCSI data for transmission over the FC-AL
loop.
