MegaRAID SAS RAID Controller Characteristics
Technical Specifications
The supply voltages are 12 V ± 8 percent (from the PCI edge connector only) and 3.3 V ± 9 percent (from the PCI edge
connector only). The following table lists the power supply for the RAID controllers for each of the three states at the
different voltages.
3.3.4.4 Operating and Nonoperating Conditions for MegaRAID SAS 9260 RAID Controllers
For the MegaRAID SAS 9260-4i, SAS 9260-8i, SAS 9260CV-4i, SAS 9260CV-8i, and SAS 9260DE-8i 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 LSISAS2108 processor above the
maximum ambient temperature.
 Temperature range:
— +10 °C to +55 °C (without BBU or a Cache Vault module)
— +10 °C to +45 °C (with BBU)
— +10 °C to +55 °C (with LSIiBBU08 mode 1 through 5)
— +10 °C to +55 °C (with a Cache Vault module)
NOTE The MegaRAID SAS 9260-4i RAID controller, the MegaRAID SAS
9260-8i RAID controller, and the MegaRAID SAS 9260DE-8i RAID
controller support the LSIiBBU07 unit and the LSIiBBU08 unit, but the
controllers do not support Cache Vault modules.
The MegaRAID SAS 9260CV-4i RAID controller and the MegaRAID SAS
9260CV-8i RAID controller support the CVFM01 module and the
CVPM01 module, but the controllers do not support iBBU units.
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 (without BBU or a Cache Vault module)
— 0 °C to +45 °C (with BBU)
— 0 °C to +55 °C (with a Cache Vault module)
3.3.4.5 Power Supply Requirements for the MegaRAID SAS 9260-16i RAID Controller
All power is supplied to the MegaRAID SAS 9260-16i RAID controller through the PCIe 3.3-V rails and the 12-V rail.
Onboard switching regulator circuitry operating from the 3.3-V rails and the 12-V rail provides the necessary voltages.
The following states determine the typical current consumption of the controller:
 State 1: During a drive stress test
 State 2: While sitting idle at the DOS prompt
NOTE The MegaRAID SAS 9260-16i RAID controller supports the LSIiBBU07
unit and the LSIiBBU08 unit, but the controller does not support
Cache Vault modules.
