vSAN @-Node and and VSAN static route

[mutthu]

I am researching on 2-Node VSAN networking and have a question , I hope someone will shed light on this.

We will have 2-Node ESXi hosts in a small office  and a witness appliance in the HQ cluster.

I am planing to put the witness on the management network which has inter-site routing in place.

I am reading a blog post in which they mentioned about VSAN routing as below,

esxcli network ip route ipv4 add –n remote-network -g gateway-to-use

Should we need that routing on the VSAN data nodes if we use witness appliance?

Hello mutthu​

This is only applicable if there is no direct route the Witness from the configured vsan vmk e.g. if you wanted to just have vsan data traffic on the data-nodes and not split out the witness traffic on its own vmk, then you would need to configure a static route for traffic destined for the witness to go out via the Management network.

The alternative to this is to just configure the witness traffic on the Management network.
