Hello,
After considering all of your advices, i finally bought and received my items
!!!
MHEA28-XTC + HP IB 4X DDR (Ref : MHGA28-1TC) + SFF-8470 Cable
I flashed each one to the last fw version.
Initially, i had setup OpenSM to run as a service on each computer (2 * Win 7), as i had read that even if 2 OpenSM are running, as on is "detected", the other one becomes inactive... But, finally, I had to only keep one OpenSM starting and running, in order to have the network working.
Well, once done, i made some benchmarks after learning about the Infiniband tools (that were new to me).
I admit have been disappointed : some file transfers between smb folders, some iperf tests (playing on TCP window size), etc., gave me an average 3Gbs transfer speed :/ ...
Unless i had misunderstood, i thought being safe from the well-known TCP/IP overhead on 10GbE networks... but while testing, i thought about the fact that, even w/ Infiniband, perhaps problem will be persistent until keeping using TCP/IP ?
Anyway, i can't find any valuable reason about such a performance decrease...
(I hardly achieved 5Gbs with unrealistic TCP window size value of 1MB).
Even if i obviously noticed a load on CPU charge, it can't be the bottleneck... (E8400 & E5300).
I found some tools about RDMA protocol and was so glad when obtained such results : +900MBs and ~5µsec latency
!!!
But, apart TCP/IP, i don't know any protocol from this new (for me) Infiniband world : RDAM, iSER, SRP, etc...
I can imagine that these protocols are dedicated to specific usages, but i think (hope) that thse protocols can possibly be setup for the basic usage : files transfers.
Obviously, i'm not requiring a quick drag-n-drop way as usual way. Just an achievable way to transfer files between 2 computers linked w/ my right new IB LAN
!!!
Without using IPoIB in order to achieve right transfer speeds (unless someone know something that could explain the performance decrease).
Thank you very much.
Sincerely,
XZed
