I'd like your opinion on how you would set up your vMotion network if you had the following network interfaces in your server:
2 x 10 Gig
8 x 1 Gig
I currently have my setup as follows:
vSwicth Nics MTU Load Balancing
vSwicth0 2 x 1Gbps 1500 Virtual Port ID
vSwicth1 2 x 10Gbps 1500 Virtual Port ID
vSwicth2 4 x 1Gbps 9000 Virtual Port ID
There is 2 x 1Gbps cards that are not in use (Spare).
I've tested my vMotion network with 1,2,3, and 4 interfaces up during my testing and had the following results (I closed switch ports down during the testing); also the same VM using 64GB RAM was used:
Number of NICs Time to vMotion Image
1 34 Sec
2 41 Sec
3 73 Sec
4 74 Sec
Does anyone have any theories on why it takes me longer to move the images when I have more interfaces in the vMotion vSwitch?
Also, I'd be interested in how you'd set up the interfaces in this network.
If you have spare interfaces, then you may want to use them for a dedicated vMotion network using a multi-NIC setup. If you didn't configure multiple vmkernel ports with those multiple adapters, you weren't utilizing them. There's a KB that defines this design and how to configure it here which I'd recommend.
