Overview

PCIe 4.0 is the notable feature of the ThinkSystem RAID 540-8i, part number 4Y37A78834. The newer interface suits current-generation ThinkSystem servers, while the adapter itself is a basic design: eight internal ports and no cache (0 GB).

It supports 12Gb SAS and 6Gb SATA drives, with RAID levels 0, 1 and 10. Those cover striping, mirroring and mirrored stripes, a good match for boot volumes and straightforward arrays that do not need parity protection.

Choose it when you want a low-complexity hardware RAID card in a PCIe 4.0 server. If you need parity RAID or write caching, look at higher models in the ThinkSystem range. Verify server compatibility before ordering.
