Dell PowerEdge T420 RAID Controllers & Batteries

The Dell PowerEdge T420 server has several options for RAID controllers. Adapter cards have full-height brackets and are installed in a dedicated storage slot for internal RAID configurations or a PCIe riser slot in the case of external RAID setups.

PERC H310: The PERC H310 controller is a low-profile, base controller that offers support for RAID levels 0, 1, 5, 10, & 50. With data transfer rates of up to 6Gb/s per port, the H310 will accommodate faster drives for a total of up to 16 drives in a RAID configuration or 32 drives in non-RAID configurations.

PERC H710: The PERC H710 controller includes all the features of the above H310 controller and adds support for RAID levels 6 & 60 while also providing 512MB non-volatile flash battery-backed write cache. H710 controllers also support up to 32 logical drives and self-encrypting drives (SED).

PERC H710P: The PERC H710P is the same as the H710 with increased non-volatile flash write cache to 1GB.
