Bilich,
Reach out to Jake Carrol at Uni of QLD
UQ have been playing with NFS over 10GB / 40GB and 100GB Ethernet
and there is LOTS of tuning that you can do to improve how things work

Subject: [gpfsug-discuss] does AFM support NFS via RDMA
Date: Tue, Jul 11, 2017 7:36 PM
Hello,
We run AFM using NFS as transport between home and cache. Using IP-over-Infiniband we see a throughput between 1 and 2 GB/s. This is not bad but far from what a native IB link provides – 6GB/s . Does AFM’s nfs client on gateway nodes support NFS using RDMA? I would like to try. Or should we try to tune nfs and the IP stack – I wonder if anybody got throughput above 2 GB/s using IPoIB and FDR between two nodes?
We can’t use a native gpfs multicluster mount – this links home and cache much too strong: If home fails cache will unmount the cache fileset – this is what I get from the manuals.
We run spectrum scale 4.2.2/4.2.3 on Redhat 7.
Thank you,
Heiner Billich
