What is 802.3ad link aggregation?  Tell you what - buy the box and I'll tell ya how it works ;)
 
Seriously, though, its a networking protocol for ethernet cards and ethernet switches to be aware of flow relationships - i.e. it makes the switches and hosts aware that the ethernet card attached to port 1 and the one attached to port 5 are actually part of the same node.  So, nodes become aware of how to redirect traffic in case of a failure, as well as how to load balance
 
AIX, right?  Here's a link to IBM's discussion on it for the p-series:

Good luck,
Matt

On our appliance, to get around the irritating load-balancing+failover issue, we're using 802.3ad link aggregation.  Trying to load-balance Gigabit is really an exercise in futility - almost all of the performance improvement comes from improved interrupt queuing (and even that is already mitigated on the card through coalescing interrupts).  The real benefit is the failover - that works very very well.
 
Thanks,
Matt
