Currently I have my ESXi hosts installed with 4 10GBit Fiber cards. I use 2 of them for my VM data traffic. And two of them for Vmotion traffic.
I want to run my VMotion network over the 2 VM data traffic cards now, so I can free up fiber ports. I checked my traffic coming from the ESXi hosts and I only do about 1 Gbit maybe 2 Gbit.
Still my co-worker who is senior to me tells me I cannot run VMotion over the 2 Fibers cards I use for my VM traffic(active-standby mode), that it will cause problems and eat up all my bandwidth when I do VMotions. I am not a networking person, it seems unreasonable to assume though that a VMotion could eat up so much bandwidth. He also stated it just would not work, but to me its just adding the appropriate VLAN to my 2 VM data nics, and moving the VMotion kernel port there.
Could someone explain why my idea is bad? I am simply trying to do a cost savings by freeing up valuable 10GBit ports.
