Hi Paul,
We do heavily rely on LNet routers to connect our clusters to our
storage systems, some suing FDR, some using EDR, and mixing up
different IB generations in the same host is not an issue.
HDR kind of requires PCIe Gen4 though (or 2x PCI Gen3 ports, but...),
so that could be a limiting fa
I have a cluster with Dell blades. The Chassis has FDR, but the TOR IB
switches are only QDR. No problems

Hi Paul,
if that is a Mellanox network I would have thought that putting in a single,
dual port HDR InfiniBand card would do the trick as well. From what I
understand, the HDR will use the slower FDR speed when the other end is only
EDR.
I done a similar setup with a mixed network where the sw
i don't have HDR, but i do have FDR/QDR/EDR/10Gb all in the same
server acting as an lnet router. seems to work fine

We are looking to bridge our FDR fabric to our HDR fabric via LNET and
we had a question about whether a single machine can have 2 different IB
cards simultaneously. Does anyone have any experience with that or know
if there are any hitches with having a single box with a FDR card and a
HDR car
