Thanks for your answer, Sabuj. However, I am not sure I understand what you mean by trying with ipoib.
Do you mean specifying "transport tcp" and using the ipoib ips/hostnames for the bricks?
If you manage to find a way to overcome this performance limitation, please share with us your solution.

Regards,
Adrian

I've seen the same 100MB/s limit (depending on block size of transfer)
with 5 bricks in a stripe and have yet to try ipoib, which I hear
improves performance over rdma for some reason.
