That's what I thought you meant. We're not using the distributed switch settings; each blade has it's own configuration.
About how many VM's are you running per host? I realized 10Gb is a large pipe, and most servers don't even push a 1Gb nic, but we're running about 20VM's/host. I'm really uneasy about running all that through a single NIC, even if it is 10Gb
