provide ride-through during a power glitch; however, the
BBU is capable of sustaining memory content for hours at a
time.
The FC2500 is capable of monitoring a customer provided
UPS. The FC2500 controller fault management features are
based on the SCSI-3 Enclosure Services (SES) device
interface.
An SES firmware process handles all enclosure fault
management. The process polls the environment every ten
seconds. Failures with disk drives are handled by the
FC2500 controller firmware with other failures such as fans,
power supplies, and temperature sensors being handled
directly by the SES device. The FC2500 controller firmware
communicates with the SES device via Send Diagnostics and
Receive Diagnostics SCSI commands. The device elements
supported by the SES process include: device (disk drive),
power supply, cooling, temperature, Enclosure Services,
controller electronics, aubible alarm, and uninterruptible
power supply.
