Arbitrated Loop
The Fibre Channel Arbitrated Loop (FC-AL) is an ANSI standard designed to
provide shared bandwidth for devices on the loop using low cost Fibre
Channel cables. A simplified FC-AL consists of a server equipped with a Fibre
Host Adapter, a Fibre Channel Storage Hub, and a RA4100 with a RA4000
Controller installed. SCSI protocol is established over the FC-AL.
Each port on the arbitrated loop has its own identity. Any port on the arbitrated
loop may arbitrate for control of the loop. Once it has control of the loop, and
the targeted port responds, bi-directional communication takes place. Only one
pair of ports on the loop may communicate at a time as a point-to-point
connection.
Figure D-2 shows a Fibre Channel Arbitrated Loop configuration with one
server, one Storage Hub, and two RA4100(s).
