Dell PERC H710P 1GB NV Cache RAID Controller — PK2W9

This PERC H710P is a RAID controller carrying 1GB of non-volatile cache, supplied under Dell part number PK2W9.

Controller and disk health can be monitored from the server’s management console. The controller must match the backplane it connects to, as the backplane decides which drives it can see. Where parts look alike, the Dell part number settles which revision you have. The non-volatile cache is designed to protect cached writes if power is lost, which is what makes write-back caching safe to use. As a Dell PERC it is intended for PowerEdge servers; check your server’s supported controller list. Hardware RAID offloads parity calculations from the host and presents the array to the operating system as ordinary volumes. The part number PK2W9 is the reliable reference when checking this controller against your system.

It is supplied certified refurbished: inspected, bench-tested and function-checked in Johannesburg before release.
