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 BBU)

0 °C to +45 °C (with BBU)

Power Supply Requirements for the MegaRAID SAS 9280-16i4e RAID Controller and the
MegaRAID SAS 9280-24i4e RAID Controller

All power is supplied to the MegaRAID SAS 9280-16i4e RAID controller and the MegaRAID SAS 9280-24i4e 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 drive stress test

NOTE

The MegaRAID SAS 9280-16i4e RAID controller supports the
LSIiBBU07 unit and the LSIiBBU08 unit, but the controller does not
support Cache Vault modules.

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.

3.3.4.22

Operating and Nonoperating Conditions for the MegaRAID SAS 9280-16i4e RAID Controller and the
MegaRAID SAS 9280-24i4e RAID Controller

The operating (thermal and atmospheric) conditions for the MegaRAID SAS 9280-16i4e RAID controller and the
MegaRAID SAS 9280-24i4e 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 LSISAS2108 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 LSIiBBU08 mode 1 through 5)

NOTE

The MegaRAID SAS 9280-16i4e RAID controller and the MegaRAID SAS
9280-24i4e RAID controller support the LSIiBBU07 unit and the
LSIiBBU08 unit, but the controllers do not support Cache Vault modules.
