Hi, Is it possible to assign additional IP to nutanix cluster? Scenario is as follows: 1. Having network class A with 10.x.x.x which is used for CVM, hypervisor communication during configuration. 2. Cluster virtual IP is also from 10.x.x.x range. 3. Added additional IP range of 172.x.x.x to CVM, Hypervisor. 4. Is it possible to add additional IP range IP of range 172.x.x.x to cluster virtual IP? Thanks

Yes-ish. It's possible, but I'll admit, its a very manual process. Though, I dont think you can assign 2 cluster VIPs. A future release will support this in a more automate fashion.

Hi, Thanks for inputs. Already assigned secondary IP & interface for CVM. But how to mention secondary IP for cluster?

I'm 99% positive we do not allow a secondary VIP

If you absolutely require it, it may be worth while to put the "Primary" network as this "new" set of IP Addresses and assign your VIP that way

That all said, whats the use case here? Why do you need to IP Address your system twice over?

We have separate network for Internet (172.x.x.x) & Data traffic (10.x.x.x & not routable) CVM are using data network for communicating with each other & service NFS on 10.x.x.x network. Cluster IP is of 10.x.x.x network. Second network is using IP from 172.x.x.x range with is routable & can be access from outer network. Need to configure Remote site which is only accessible from 172.x.x.x network.

This may sound silly, but if you're going to expose the CVM's to both side of the network, why not just simplify and drop the 10.x network and run the CVM's on the 172 network

Can't. 10.x.x.x is using for data services & replication between CVMs.

So is the 172 network coming in over the same 10GbE interfaces? or some other separate interfaces, like the onboard 1GbE ones?

172 using 1G separate & 10 using 10G

Ahhhh, I see!

ok, that makes sense. Alright, yes, those ports would need to be open site to site.
