As an alternative to SCSI, the two SFF-8067 interfaces in the
SYM53C040 allow it to communicate data between a Fibre Channel
enclosure and the Fibre Channel host, using the SFF-8067 physical
interface and the SES protocol to monitor the power supply, cooling
system, and other alarms or status indicators in the enclosure. It also
reports this information to the Fibre Channel host controller and
generates control outputs to control system components, in response to
host commands. Figure 1.2
