There are 3 sensors placed on controller for temperature checking, they are on
core processor, PCI-X bridge, and daughter board. Controller will check each
sensor for every 30 seconds. When one of these sensors is over high
temperature value continuously for 3 minutes, auto shutdown will be triggered
immediately.
2.
The core processor temperature limit is 85°C. The PCI-X bridge temperature
limit is 80°C. The daughter board temperature limit is 80°C.

S.M.A.R.T.
(

echnology) is a diagnostic tool
for hard drives to deliver warning of drive failures in advance. S.M.A.R.T. provides
users chances to take actions before possible drive failure.
S.M.A.R.T. measures many attributes of the hard drive all the time and inspects the
properties of hard drives which are close to be out of tolerance. The advanced notice of
possible hard drive failure can allow users to back up hard drive or replace the hard
drive. This is much better than hard drive crash when it is writing data or rebuilding a
failed hard drive.
“S.M.A.R.T.”
can display S.M.A.R.T. information of hard drives. The number is the
current value; the number in parenthesis is the threshold value. The threshold values
of hard drive vendors are different; please refer to vendors’ specification for details.
S.M.A.R.T. only supports SATA drive. SAS drive does not have. It will show N/A in this
web page.
