VCS on AIX

Hi,
is anybody here experienced in running VCS on AIX and happy to give me some advice regarding configuration questions?
I expect very high network IO on my cluster - so a single gig-e network will not be sufficient - and though I would like to configure more than one network card per node and implement some load balancing - but I am not yet entirely sure what would be the best solution to realize this.
Thanks and regards
