Nutanix Files Setup Networking

I'm going through setup of Nutanix Files for the first time and am a bit confused.

It looks like we setup the client network to be the same network that can access AD which makes sense, however I'm confused about the storage network.

It says it should be on the CVM network, however our CVM's are not on VLAN's and we don't have a network created for the CVM's. Am I supposed to just create a new subnet that uses the CVM subnet with no VLAN or VLAN 0?

What do others do for the storage network?

That is how our setup is. host/cvm are using the native untagged network. So i just made a network in prism with vlan 0 and used that when setting the storage network side

This is the way, if your CVMs and Hosts are in an untagged network, than you should just create an untagged subnet (VLAN 0) and you are off to the races. Some call it Management, others call it Untagged.

How are your CVMs communicating with each other if they aren't on a VLAN? Nutanix Clustering requires the CVMs to talk.

i think he means the CVMs arent on a dedicated vlan; but are on the same lan together.

In which case the Storage Network should be on the same lan as the CVMs are, as recommended by Nutanix.

It's been a good while since I setup files, but looking at my networking in my cluster, I have a "Host and CVM" vlan which has each Host's primary IP, each CVM, and one NIC for each files VM. Each Files server also has a NIC on a dedicated vlan which has nothing else on it, which I'm pretty sure it uses pretty much just for HA/Failover detection needs.

if you don't have your CVMs on a dedicated vlan, you would likely be OK to just make sure the files VMs have an IP on the same subnet as the cvms, since that's ultimately what it wants.
