Hi

I made some further test...
Multipath is enabled on both xenservers and i have made test with 4 different network configuration on xenserver and for different network config in the opene.
i also made some performance test with 4 network bonded in balance rr in opene and 4 bonded in active active on xen.
All test with MPIO activated. Best performance was about 200MB per sec. not 400 as expected.
I can't understand the reason for that.
I noticed that even if i had 4 diff network xen is saying that i have 5 MPIO path/session ? why 5? it seems also to use the management network of Opene. Is that correct?

Can you give me some direction of understanding please?

Thanks

Andrea

I noticed the same behavior after bonding... 2 MPIO path/session and not 1...
