Dell PERC H740P 8GB NV Cache Mini-Mono RAID Controller — 0878M

This PERC H740P is a mini mono RAID controller carrying 8GB of non-volatile cache, identified by Dell part number 0878M.

Virtual disks are built in the controller’s set-up utility at boot, or from management tools once the operating system is running. Mini Mono controllers fit the dedicated storage-controller slot on the motherboard rather than a PCIe slot. As a Dell PERC it is intended for PowerEdge servers; check your server’s supported controller list. The non-volatile cache is designed to protect cached writes if power is lost, which is what makes write-back caching safe to use. Hardware RAID offloads parity calculations from the host and presents the array to the operating system as ordinary volumes. Dell part numbers identify the exact revision, which matters more than the description when several look-alike parts exist. 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. Check 0878M against the service configuration of your Dell system before ordering.

As a certified refurbished part, it is inspected, bench-tested and function-checked by our Johannesburg team before release.
