Hi, Im planning to add 2 more blocks NX-3060-G6 with 2 nodes on each block. Currently i have 2 Block Nutanix NX-3060-G6 with 2 Nodes on each block.
Current topology is 2 Block nutanix connected to Cisco 2960X with all eth interfaces connected to it. My question is, In NX-3060-G6 there are 3 Ethernet interfaces, 1 for MGMT (IPMI) and there are other 2 eth interfaces and 2 SFP+. For networking purpose,
- Do we need to use those 2 eth interfaces from each node in order to work? Or do we need to use only 1 eth interface only on each node?
- We’re adding 1 more switch Juniper EX4600, so if we need to use those 2 eth interfaces, can we separate them? 1 Eth interface to Cisco 2960X and the other goes to EX4600?
- Can i have different VLAN on each interfaces (exclude MGMT) that i connect to switch?
Sorry if my question isn’t clear enough. But i hope you do understand it. Thank you.

You can definitely keep using rj45 @ 1G speed instead of 10G until you get a 10G switch, bearing in mind that using 1G is not the best practice in production. As I said, the AHV cluster is designed to be connected via 10G at least for the intra cluster and management side.
“So, there will be 2 bridges and bonds, 1 for 1G bridges / bonds for the guest virtual machine and the other for 10G for internal management. It's correct?"
"Another question, as there is a warning that my CVM did not receive a 10G uplink, is why"
The caveat you are facing is due to unmatched best practice for connecting and it will be fixed automatically as soon as you use 10G speed on the interfaces (RJ45 @ 10G or SFP + @ 10G it doesn't matter) for the internal management network.
You are now using 1G and then the alert is triggered
If you have access to the "Nutanix Support Portal" you will find lots of documentation on best practices and more. Even if you don't have such access, you can find many AHV networking stuff related sites / blogs.
Of course practicing on a real-world environment like yours, where you can get your hands on switches, NICs, and Open Virtual Switch setup, would be the best teacher you could have.
Have fun with your AHV cluster!
