Time to bridge your homelab backplane to serious external storage iron. This is a genuine Dell PERC 5/E Dual-Channel SAS RAID Controller (Dell Part Number: 0MX961 / MX961, Board Model: UCP-51 / PWB U7511), complete with its factory 256MB DDR2 PC2-3200R ECC registered cache mini-DIMM.
Powered by LSI Logic’s battle-tested ARM-based RAID-on-Chip (RoC) architecture, the PERC 5/E is an enterprise classic built to drive direct-attached storage (DAS) arrays—such as the PowerVault MD1000 and MD3000—across external SAS cabling without breaking a sweat.
