SAF-TE Controller
The SCSI Backplane has two SAF-TE (SCSI Accessed Fault Tolerant Enclosure)
controllers that provide an interface to a disk subsystem that supports status signals, hot
swapping drives, and module monitoring.
The transport mechanism for the standardized alert detection and status reporting is the
SCSI bus. Disk drives, power supplies, cooling fans, and temperature are continually
monitored and the conditions then reported over the SCSI bus to the system. This
allows the user to react to conditions that could normally go unnoticed until data loss.
