HP Smart Array P440 RAID Controller

The HP 726821-B21 is a PCI-Express 3.0 x8 RAID controller that supports SATA and SAS drives at up to 12Gb/s. It includes 4GB of flash-backed write cache to protect data during power loss. The card provides a single internal SAS port for connecting compatible storage devices in server environments.

Suited for servers needing hardware RAID

This controller suits administrators who need a single internal SAS connection with RAID levels supported by the Smart Array P440 and the safety of flash-backed cache. It is not for builds that require more than one internal SAS port or that need external SAS connectivity.

12Gb/s transfer rate over PCI-Express 3.0 x8

The 12Gb/s transfer rate across the PCI-Express 3.0 x8 interface determines whether the controller matches the drive speeds and slot availability in the target server. Verify that the system provides a compatible x8 slot and that the connected drives support the 12Gb/s SAS or SATA standard.

Questions about this item

Is the 4GB flash-backed cache the only cache size available for the P440?

The P440 controller includes 4GB of flash-backed write cache as standard.

What real-world throughput can I expect from the 12Gb/s SAS link?

The 12Gb/s SAS interface supports up to 12Gb/s per drive; actual throughput depends on the attached drives and workload.

Does the PCIe 3.0 x8 slot limit the controller’s 12Gb/s SAS speed?

PCIe 3.0 x8 provides ample bandwidth for the single 12Gb/s SAS port and 4GB cache.
