Dell FX2S NVME compatibility

Dell FX2S NVME compatibility

I have a DELL FX2S chassis with 2 FC630 compute nodes and 2 storage nodes.

I was wondering if we can migrate to a faster storage, and so was planning to either purchase a PCIE card to place in the compute nodes to add some U.2 or similar NVME disks, or purchase a PCIE card to place in the chassis and a mezzanine card which I believe is needed to passthrough the card from the chassis to the compute node.

Since this will be a first attempt, I was wondering if someone else has tried a similar configuration, so we can avoid purchasing something that isn't compatible with what we are trying to achieve.

I am also planning to do a similar attempt in a FX2S chassis with FC430 compute nodes. This one has no storage node, just the local storage of the compute node.

Ideally I would want the FC430/FC630 to have the disks at the front so they can be swapped easily, rather than being attached to the PCIE card itself. It is not a requirement, but I would rather remove a disk without having to shut down the compute node, instead of having to shutdown, disassemble the PCIE card and unscrew the disk that I need to replace.

Finally, I would ideally like the PCIE NVME card to have hardware RAID, at least RAID 1 but ideally support at least 4 disks and hardware RAID 10.

Answers with compatible brands / models of working configurations would be great :)

Thank you in advance for any valuable insight.

Just some additional notes based on my research:

However, I am not sure if these are compatible with FC430/630 and the FX2s chassis.

Also, I would rather have a proper RAID card instead of just that expansion card DELL provides.

UPDATE November 1

Considering the first answer I received, I am providing some more details of the goal. I would like to have a RAID card on the chassis, forward that card to a compute node, and have RAID 10 on that node. The card could be something like this: https://www.broadcom.com/products/storage/raid-controllers/megaraid-9660-16i

I also enquired Dell to know if we could just swap the PERC that exists in the storage node for one compatible with NVME, but we can't.



Top Answer/Comment:

You can insert Dell-approved PCIe NVMe cards, but due to the limited number of PCIe slots, which is two per node tops for the quad-node configuration (see the link to the official Dell extension guide below in P.S.), you are restricted to an OS-level RAID1 for redundancy as your only option. Commercial software-defined storage solutions like VMware vSAN and Microsoft S2D require significantly more than just two storage devices per physical node. As a result, IBM Ceph and StarWind Virtual SAN remain your only viable options for internode replication.
