Dell PERC H740P 8GB NV Cache Full-Height PCIe RAID Controller — 1M71J

The PERC H740P is a full height RAID controller with 8GB of non-volatile cache, carrying Dell part number 1M71J.

Disk and array health show up in the server’s hardware management logs. Where parts look alike, the Dell part number settles which revision you have. Controllers of the same family can usually take over an existing array from its drives, but check firmware levels before swapping one for another. Drives connect through the server’s backplane, so the controller has to suit the backplane it is cabled to. It is the full-height PCIe card form of the controller. Set-up happens in the controller’s pre-boot utility, and arrays can be managed later from the operating system. Hardware RAID offloads parity calculations from the host and presents the array to the operating system as ordinary volumes. As a Dell PERC it is intended for PowerEdge servers; check your server’s supported controller list. Because the cache is non-volatile, cached writes are designed to survive a power cut, so write-back mode can stay on. Use the part number 1M71J to confirm the controller matches the one already in your system.

Condition is certified refurbished, and each part is inspected, bench-tested and checked in Johannesburg.
