We got 6 CORAID shelves in my workplace. On 2 of them I see AoE traffic on only 1 of the 2 NICs that are attached to the SAN switch. We got jumbo frames enabled on all devices.
Both NICs show up when I issue the aoe-interfaces command.
This wouldn't bother me too much if the throughput performance observed on the "bad" shelves using bonnie++ wasn't half of the result of the "good" shelves.
The "good" shelves are older SR1521 model and they have ReiserFS on their LUNS - not that I think it makes a difference - and the "bad" shelves are newer SR2421 model and have JFS.
Any help as to what is going on and how to rectify this would be greatly appreciated.
BTW: even the lower performing shelves outperform another iSCSI device we got, but that is another story.
