3-6 ServeRAID M1115 SAS/SATA Controller Characteristics
3.3.4 Power Supply Requirements for the ServeRAID M1115 SAS/SATA
Controller
All power is supplied to the controller through the PCI Express 3.3V rails
and the 12V rail. Onboard switching regulator circuitry operating from the
3.3V rails and the 12V rail provide the necessary voltages. The following
states determine the typical current consumption of the controller:
•
State 1: During a hard reset
•
State 2: During a disk stress test
•
State 3: While sitting idle at the DOS prompt
The supply voltages are 12V ± 8 percent (from PCI edge connector only)
and 3.3V ± - 9 percent (from PCI edge connector only).
Table 3.6 lists
the power supply for the controller for each of the three states at the
different voltages.
3.3.5 Operating and Non-operating Conditions
The operating (thermal and atmospheric) conditions for the ServeRAID
M1115 SAS/SATA controller are:
•
Relative humidity range is 20 percent to 80 percent noncondensing
•
Airflow must be at least 200 linear feet per minute (LFPM) to avoid
operating the Intel IOP333 processor above the maximum
ambient temperature
•
Temperature range: +
