[AusNOG] VM throughput to network

[Skeeve Stevens]

Hey all,

Got an interesting debate with some server guys.

It is my 'theory' (not backed up my technical facts) that a VM should be able to use more than 1Gig of throughput when a VM (VMware) is on a server that has a bonded NIC to a switch which 'in Cisco talk' is doing a ether-channel/port channel to the server - the case in point is 2 cables together, but in theory should be able to go to 4 or more.

The server guys are suggesting that a single VM can only go out one of the NIC ports and therefore only get to a maximum of 1Gb throughput.

Is this true and is there any docs for either HP DL 380's, VMware which would support either stance?

Just trying to verify a theory, and since there would be a ton of people on this list which do VMware, NIC bonding into switching, I thought it would be a great place to ask.
