reServer i31125 - Using M.2 (NGFF) Key B+M To Key M Adapter for using NVMe drives

I have a question on reServer i31125.

Can the B-Key slot (with PCIe 3.0 x2) be used with m.2 M-Key NVMe drive using the M.2 (NGFF) Key B+M To Key M Adapter?

My understanding is the B-Key slot is connected to the PCIe Lane and does not have SATA controller, so ideally it should work. Please correct me if I am wrong.

Any help would be appreciated.

Hi there,

So, I looked at the spec’s and it looks to me from a hardware adapter perspective it should work, The adapter in question is a passive adapter, just rerouting pins—no protocol translation. what OS is on the reServer i3
it should work, and here’s why:

  • The B-Key slot on the reServer i31125 provides PCIe x2, and that’s the key point.
  • The adapter (B+M to M-Key) is just a passive pin rerouter — it doesn’t change the signaling or protocols, it simply allows a different-shaped M-Key drive to physically fit the B-Key slot.
  • As long as the M.2 NVMe SSD supports PCIe x2 mode (which many B+M keyed drives do, and some M-key-only ones as well), it will enumerate and function.

With all that in mind, just don’t use a high end NVME that’s 4x only that won’t work and it’s a waste of money (i3) If your trying to boot from it that could only be if the bios supports it :crossed_fingers:

the PCIe x2 NVME SSD are way more affordable SSD’s
double check you ssd spec’s and post it.
I think it will.

Maybe a Seeedineer could comment , they look like pretty decent starting point IMO of a hardware kit. :+1:
