I have a cluster of 94 nodes, all dual hexacore (12 cores per node) and using QDR IB. I have not run into any networking issues as a result of overloaded network, and my storage system (when healthy) has withstood multiple nodes running 12 jobs, as well as hitting loads of 1000 jobs per day across the cluster as a whole (it had done over 500K jobs in 9 months of production and just recently over 100K jobs in two months).
