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.
NOTE The MegaRAID SAS 9266-8i RAID controller supports the CVFM02
module, CVPM02 module, and the LSIiBBU09 unit.
NOTE The charging circuitry for the battery pack on the optional iBBU
battery-backed daughter card uses +12 V. If the BBU daughter card is
mounted, 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.
NOTE If a CVFM02 module is attached to the RAID controller, and the
CVFM02 module is connected to a CVPM02 module, the following
power consumption figure applies in addition to the +12-V
consumption figures listed in the previous table:
 During CVPM module charge cycle: 500 mA in +12-V current.
3.3.4.14 Operating and Nonoperating Conditions for the MegaRAID SAS 9266 RAID Controllers
For the MegaRAID SAS 9266-4i RAID controller and the MegaRAID SAS 9266-8i RAID controller, 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 LSISAS2208 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 LSIiBBU09 mode 1 through 5)
— +10 °C to +55 °C (with a Cache Vault module)
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)
