Pushing vmware on to new IBM x3850x5 40 core servers with 512GB of RAM.
This is an uplift from previous 36 cores.
We have been loading up with lots of IO cards but it turns out its overkill. Recent review a SAN IO showed that the busiest 8 node clusters peak COMBINED IO did not exceed 1/10th of a 4GB SAN card capability. Even the network cards did not get stressed on 1gb connections.
As long as your clusters are not stressed IO is not an issue. Note to self ....scan for iso images mounted to vm's and drop them as it will stop vmotion.
