RAID controller for internal SAS arrays

This Intel RMS3CC040 is a 12Gb/s SAS RAID controller on a PCIe 3.0 x8 plug-in module. It provides four internal SAS ports and supports RAID levels 0, 1, 5, 6, 10, 50 and 60. The card is designed for PC platforms running Windows or Linux.

Suited for servers needing hardware RAID

The four-port design fits builds that connect up to four internal SAS devices directly to the controller. Systems requiring more than four internal ports or external SAS connectivity will need a different controller. Buyers who need software RAID only or who lack a PCIe 3.0 x8 slot should consider other options.

12Gb/s SAS over PCIe 3.0 x8 with four internal ports

The single decisive specification is the combination of a PCIe 3.0 x8 host interface, 12Gb/s SAS signalling and exactly four internal SAS ports. This determines whether the controller fits the available slot, matches the drive speed and provides enough ports for the planned array.

Questions about this item

How does the 12 Gb/s SAS rating translate to actual drive throughput?

Each of the four internal ports can move up to 12 Gb/s, so four drives can saturate the PCIe 3.0 x8 host link without bottlenecking the controller.

What does the PCIe 3.0 x8 host interface limit in practice?

The x8 lane width caps total bandwidth to roughly 8 GT/s per lane, which matches the combined 12 Gb/s SAS port potential.

What physical space and mounting does the plug-in module require?

It fits a standard low-profile PCIe slot and ships with standoffs for secure mounting in compatible server chassis.
