Network I/O Control

Hey guys,
I was curious if one of you guys know if you can enable Network I/O on a vDS while the vDS is being used and not have traffic going over it get disconnected? -- I'm pretty sure you can just enable it, but just to play it safe I figured I'd ask just to make sure my brain is thinking this correctly.
I'm essentially looking to avoid taking down a cluster to enable Network I/O on datacenter of over 2000 VM's.

Yes. NIOC will not disconnect.2018 Certification Goals: Maybe VMware Sales Cert

Perfect, want to throttle backup traffic for our EMC Avamar and our EMC VNX SAN until we get a OOB fabric for just storage.

I just want to point out that NIOC is not a throttling mechanism. It is just a way to manage QoS for specific traffic in the network stack in a ESXi host. If you want to throttle the specific traffic you will need to use either ingress (for outward) and ingress (for inward) traffic shaping available on a per port group level in the vDS.
Also the throttling is dependent on the backup network layout used for the system. Default it uses the management vmkernel.
