I was recently designing a vSphere Replication and SRM solution for a client and I stated we would use static routes on the ESXi hosts. When asked why, I was able to 1. discuss why the default gateway on the management network wouldn’t work and 2. present some options as to how we could separate the vSphere Replication traffic in a way that would allow flexibility in throttling its bandwidth usage.
You won’t see listed here Network I/O Control because this particular client didn’t have Enterprise Plus licensing and therefore wasn’t using a vDS. In addition, this client was using a fibre channel SAN on top of Cisco UCS with only a single VIC in his blades. This configuration doesn’t work well with NIOC because it doesn’t take into account FC traffic which is sharing bandwidth with all the Ethernet traffic NIOC *is* managing.
