Currently that is not done. Are you planning > to use IPoIB for real workloads? Under FBSD 10 I was using it to run iSCSI using IPoIB between two boxes (with ZFS mounted atop of that). This worked, and performance was 'good' - but the boxes would eventually 'lose site' of each other [I think at least one other person had the issue - worse (i.e. more often) than I did] Knowing there's been a lot of changes to IB in 11 I thought I'd give that a go... I can go back to FBSD 10 - I'd need to solve the intermittent "loses site" issue then (with the code the 10 is running). I guess overall - moving back to 10 is looking like the better option... -Karl
