A vSphere 5 implementation consists of a fully automated DRS cluster with the following vNetwork Standard Switch configuration.
1. Switch A: two vmnics, one port group named sFTP-PG
2. Switch B: one vmnic, one port group named Web-PG
3. All vmnics are trunked to the same physical switch DRS has been configured with an anti-affinity rule for all virtual machines in the Web-PG so that no more than half of the virtual machines run on any given host. The virtual machine on WebPG are experiencing significant network latency. The network team has determined that a performance bottleneck is occurring at the ESXi host level.
Which solution will require the least amount of administrative work and least amount of service interruption?
A.
Move a vmnic from Switch A to Switch B on each host.
B.
Mograte Web-PG to Switch A and sFTP-PG to Switch B on each host.
C.
Convert the three Switcg Bs to a single vNetwork Distributed Switch.
D.
Use vMotion to redistribution some of the VMs in Web-PG to a different ESXi host.
Answer A seems best. It is the least amount of work and will not result in service interruption. Switch A already has two NICs so removing one will not disconnect vms on switch A. VMs on switch B are the ones having performance issues. All uplinks are trunked to the same physical switch, so moving an uplink from A to B seems logical. Answer C would work, but would be more work and would result in service interruptions.
