Before the release of VMware vSphere 5, designing a vMotion network was relatively easy as it was straightforward. vMotion in VMware vSphere 5.0 and above is able to leverage multiple NICs. By default, a single vMotion will use only one NIC regardless of how many NICs are set up for vMotion. Running multiple vMotions at the same time will utilize multiple NICs. Implementing a multi-NIC vMotion will allow a single vMotion operation to use multiple NICs at once and reduce the duration of that operation.
To step through this recipe, you will need one or more running ESXi Servers (licensed with Enterprise Plus for vDS), each with two available NICs, a vCenter Server, and vSphere Web Client. No other prerequisites are required.
