Dell PERC H740P 8GB NV Cache Full-Height PCIe RAID Controller — 3JH35

This PERC H740P is a full height RAID controller carrying 8GB of non-volatile cache, supplied under Dell part number 3JH35.

When replacing a controller, check firmware levels first; a controller of the same family can usually pick up the existing array from the drives. Where parts look alike, the Dell part number settles which revision you have. Controller and disk health can be monitored from the server’s management console. 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 3JH35 is the reliable reference when checking this controller against your system.

Our Johannesburg team inspects and bench-tests the part before it is released as certified refurbished.
