Technical Specifications
3.3.4.3 Power Supply Requirements for the MegaRAID SAS 9361 RAID Controllers
All power is supplied to the MegaRAID SAS 9361 RAID controllers through the PCIe 3.3V rails and the 12V rail. Onboard
switching regulator circuitry operating from the 3.3V rails and the 12V rail provides the necessary voltages. The
following states determine the typical current consumption of the controller:
 State 1: While sitting idle at the DOS® prompt
 State 2: During a drive stress test
 State 3: Power on the controller with a deeply depleted CacheVault Power Module (CVPM) attached
The supply voltages are 12V ± 8 percent (from PCI edge connector only) and 3.3V ± 9 percent (from PCI edge
connector only). The following table lists the power supply for the RAID controllers for these three states at the
different voltages.
3.3.4.4 Operating and Nonoperating Conditions for MegaRAID SAS 9361 RAID Controllers
For the MegaRAID SAS 9361 RAID controllers, the operating (thermal and atmospheric) conditions are as follows:
 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 LSISAS3108 processor above the
maximum ambient temperature
 Temperature range: 10 °C to +55 °C (with or without the CVFM04 module attached)
The parameters for the nonoperating (such as storage and transit) environment for these controllers are as follows:
 Relative humidity range is 5 percent to 90 percent noncondensing.
 Temperature range: –40 °C to +70 °C
3.3.4.5 Power Supply Requirements for the MegaRAID SAS 9380-4i4e RAID Controllers
All power is supplied to the MegaRAID SAS 9380-4i4e RAID controllers through the PCIe 3.3V rails and the 12V rail.
Onboard switching regulator circuitry operating from the 3.3V rails and the 12V rail provides the necessary voltages.
The following states determine the typical current consumption of the controller:
 State 1: While sitting idle at the DOS prompt
 State 2: During a drive stress test
 State 3: Power on the controller with a deeply depleted CacheVault Power Module (CVPM) attached
