designed to meet short-term startup power demand as well as
steady state conditions.
Sans Digital has supported the fixed value staggered power up
function in its previous version firmware. Sans Digital RAID controller
has included the option for customer to select the disk drives
sequentially stagger power up value. The values can be selected
from 0.4 sec(s) to 6 sec(s) step which powers up one drive.
3 .7.6.11 Spin Down Idle HDD
This function can automatically spin down the drive if it hasn't
been accessed for a certain amount of time. This value is used
by the drive to determine how long to wait (with no disk activity,
before turning off the spindle motor to save power.)
3 .7.6.12 Empty HDD Slot LED Control
The firmware has added the "Empty HDD Slot LED" option to
setup the Fault LED light "ON "or "OFF". When each slot has a
power LED for the HDD installed identify, user can set this op-
tion to "OFF ". Choose option "ON", the EliteRAID RAID control-

backplane that can report HDD temperature status to the
controller. However, PCI cards do not use backplanes if the
drives are internal to the main server chassis. The type of
enclosure cannot report the HDD temperature to the controller.
For this reason, HDD SMART Status Polling was added to enable
scanning of the HDD temperature function. It is necessary to
enable “HDD SMART Status Polling” function before SMART
information is accessible. This function is disabled by default.
