I'm installing ESXi on M620 blades, with 2 physical NIC's being partitioned to 4 virtual NIC's each for a total of 8 NIC's. ESXi is binding the first 2 NIC's to management. When trying to ping the management interface only 5-10% of the packets reply. After unbinding the first NIC, and leaving only the 2nd NIC for management, there were no problems with packet loss. I then tried binding random NIC's from 2-8 and no issues with any of them. The only problem is when using the first NIC, either by itself, or with another set of ports; running persistent pings will drop many packets. This issue has been reproducible on multiple M620 blades. Is there anything special about the first NIC port when you using partitioning?
