Network I/O Control V4 and vSphere 6
VSphere 6 introduces a new version of Network I/O Control. This new version allows network reservations at the vnic level. What follows is a simple demonstration on how to set this up. This allows the critical virtual machines to have a guaranteed amount of network bandwith. This feature is compatible with DRS.
Note: Althought the vSphere Client can connect to the vCenter Server, you can't use the C Sharp client for this. Notice the following error:
Step 1. Create a Distributed Virtual Switch and migrate at least one vm to it. Make sure that Network I/O Control is enabled. This is what it should look like once you finish.
Step 2: Go to the Networking View, select Manage and specify the network related reservation for the Virtual Machine Traffic system defined pool.
Step 3: Create your User Define Network Pool and specify its reservation.
Step 4: Associate your Port Group to your Network Pool.
Step 5: Specify the reservation at the vm level by editing its settings.
