•
threshold comparison functions
•
SMI (systems management interrupt) generation
•
watchdog timer and certain GPIO (general purpose input/output) functions
•
fault-resilient booting

information interface
•
current event status and sensor readings when polled by System Management Software
Hot-swap Controller (HSC)
Where located: on the disk backplane
What it does:
•
implements the SAF-TE command set
•
controls the fault lights and drive power-on
•
provides a path for management information via SCSI
•
retrieves drive fault status, backplane temperature, and fan failure information via the IPMB
