[Lustre-discuss] max write speed of QDR HCA card

[lakshmana swamy]

  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
