In the past, we have built clusters with metro sync (AHV) at 2 Locations and a 3rd for witness.
Customers want to get an infrastructure what can tolerate the loss of one Location.
Can we stretch a 3 node Cluster across all 3 Locations, one node in one Location?
RTT is less than 5ms.
In this case, what network topology is required?
No you shouldn't. The cluster nodes should be in the same datacenter.
Placing the nodes that form a Nutanix cluster in multiple data centers or availability zones connected by stretched L2 networks, or in data centers that have a remote link between the two locations, isn't supported.
Please refer to the networking best practice guide from Nutanix: Physical Networking
