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 switch is FDR but some of the nodes are only QDR and here the connection is throttled down to QDR.
I might, of course, be wrong here. All the best from a sunny London Jörg Am Freitag, 10.
