Dell PERC H730P 2GB NV Cache Mini-Mono RAID Controller — 3V42G

This PERC H730P is a mini mono RAID controller carrying 2GB of non-volatile cache, identified by Dell part number 3V42G.

Look-alike parts can differ in revision, and the Dell part number is what tells them apart. 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. When replacing a controller, check firmware levels first; a controller of the same family can usually pick up the existing array from the drives. Set-up happens in the controller’s pre-boot utility, and arrays can be managed later from the operating system. 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. Check 3V42G against the service configuration of your Dell system before ordering.

Sold as certified refurbished, the part passes inspection and a bench test in Johannesburg before release.
