NIC change on hosts - best practice for vMotion / Managment
We are going to replace the 4 x 1GB NIC Mezzanine cards in our 4 ESXi hosts with new 4 x 10 GB cards. The four NICs on the mezzanine card currently have the vMotion and Management networks connected to them. VM network traffic is through 2 x 10 GB NICs on each host. We will need to move vMotion and Management networks to the two 10 GB NICs while the cards are replaced.
Given that vMotion traffic can saturate a link, the question I have is whether it is better to a) set traffic filtering on the two vMotion portgroups and then assign their vmnic's to the two 10 GB NICs or b) should I assign the VM network and Managment network to one of the 10GB NICs and the vMotion network to the other 10 GB NIC?
