UCS B200 blades killing network connectivity

We have Cisco UCS 5108 chassis full of B200 M3 blades. We installed Vmware on each blade and each blade has unique MAC and unique IP. MAC inside vmware matches the mac inside UCS manager for each particular blade.


The problem is if i power one server i can ping it and connect to it. When i power 2nd server and it comes online, i can't ping 1st server anymore. If i power on 3rd server i can ping it but then i can't ping server1 or server2. All servers are on same blade chassis so it looks like a network problem within chassis. The problem is interesting and i can't find any logic in this. Anyone had similar issues?

Just an update, looks like it

Just an update, looks like it is related to the EMC XtremIO storage where we use 1 image with snapshots to boot several ESXi hosts.
