Hi Lakshmana,
You can use standard ofed tools like ib_rdma_bw to check Infiniband
bandwidth between pair of nodes.
Lustre provides lnet selftest tool for measuring IB bandwidth between
pair or group of nodes. Check lustre manual for how tos.
Finally, can you post IOR parameters you are using?
Cheers,
Atul

Dear All,
Whats the maximum write speed can be achieved with Infiniband QDR
HCA card.
The Question arised from my lustre setup where Iam not able to
exceed 500MB/s (write speed) with two OSSs and one MDS
Each OSS has four OSTs and one HCA card. I would like to know which
is the bottleneck here.
I have been using IOR for benchmarking
Thank you
