Dear all,
I am helping a client to design a new VM farm, and their network team adopted leaf-spine architecture for the network. Currently, there are 3 leaves (2 switches in each leaf) and 2 spine switches.
I would like to know if there is any best practice on host redundancy, and VM affinity setting for this setup.
Mainly, I would like to know:
1. Shall there be N+1 or N+M (number of leaf) for number of host servers?
2. Do we need to configure affinity for VM in this case, such that in case of vMotion, it will choose servers in the same leaf instead of moving to servers connecting other leaf?
Best Regards,
Rayson
