VMotion takes out the network

Over the weekend we had an issue with a switch in the back of our Dell M1000. It appeared to have died. During that time when we did a vmotion we lost connectivity to servers in the same physical switch that the M1000 chassis switch is connected to.

Our network engineer has now replaced the switch in the M1000 however the issue of connectivity loss when doing a vmotion still occurs. I stumbled upon this post which is very similar, (we too have everything on the same subnet) http://communities.vmware.com/thread/306862 We are still on esx3.5 but wandered if it was relevant. We'll have to ask the netwrok guys to do some monitoring when we try it again.
