We run our Isilon systems (OneFS 8.0.0.6) with active/passive failover. When we put them in OneFS had a bug with LACP and wouldn't work, forcing us to go active/passive. Due to other problems, we just discussed with them converting from active/passive to LACP, but EMC said there is still a bug in LACP support.
