Your waiting on io will shoot up real quick if the disks slow down even a bit. My experience is you'll probably want more machines unless you're not pushing your disks (in which case why run lustre?)
We have about 85TB of disk (in 24 luns) hanging off 4 PE2950's with those same specs. They are set up in failover pairs (each handles 6 luns) but I can't run too long on a single machine before it starts thrashing when it takes over the other nodes 6 luns.
