MegaRAID SAS RAID Controller Characteristics
Technical Specifications
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 a Cache Vault module)
0 °C to +55 °C (with a Cache Vault module)
3.3.4.27 Power Supply Requirements for the MegaRAID SAS 9286-8e RAID Controller
All power is supplied to the MegaRAID SAS 9286-8e 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 hard reset
State 2: During a disk stress test
State 3: While sitting idle at the DOS prompt
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 controller for each of the three states at the
different voltages.
NOTE The MegaRAID SAS 9286-8e RAID controller supports the LSIiBBU09
unit, but the controller does not support Cache Vault modules.
NOTE The charging circuitry for the battery pack on the optional iBBU
battery-backed daughter card uses +12 V. If the iBBU daughter card is
mounted on the controller, the following power consumption figures
apply in addition to the +12-V consumption figures listed in the
previous table:
During trickle charging of the battery pack: Not applicable
(no trickle charge for Li-ION).
During fast charging of the battery pack: 250 mA in +12-V current.
3.3.4.28 Operating and Nonoperating Conditions for the MegaRAID SAS 9286-8e RAID Controller
The operating (thermal and atmospheric) conditions for the MegaRAID SAS 9286-8e RAID controller 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 LSISAS2208 processor above the
maximum ambient temperature.
Temperature range:
+10 °C to +55 °C (without BBU)
+10 °C to +45 °C (with BBU)
+10 °C to +55 °C (with LSIiBBU09 mode 1 through 5)
Table 37 Power Supply for MegaRAID SAS 9286-8e RAID Controllers
PCI Edge Connector State 1 State 2 State 3
+3.3-V supply 934 mA 901 mA 893 mA
+12-V supply 807 mA 542 mA 541 mA
+3.3-V auxiliary supply
(iBBU applications only)
14 mA 43 mA 43 mA
Total Power 12.812 W 9.619 W 9.581 W
