NVME RAID - VMWare Data Store


#1

Good Evenning,

We are working on a server with 6 2.5" NVME drives. The goal is to use these drives for a VMWare data store with some level of hardware redundancy. Surviving one drive failure would be acceptable.

I have heard NVME RAID controllers are not common and part of the reason is a performance reduction compared to directly presenting each NVME drive as a block device.

Is there a better more modern approach than using a RAID controller.

Thank You!
Justin

Ensure to test that hot swap is working before you put it in production.

Oh shit… they’re 2.5" drives? Yeah the only NVMe RAID controllers that I know are any good are the ones where you throw a few M.2 drives on a PCB board with the raid controller built in.

What kind of throughput do you need?

Good point, we do have a node that is not in production yet.
