we are using a VDI solution that connects to Prism REST interface to deploy Virtual Machines as they are requested.
When we are upgrading the cluster, the VDI solution can't connect to Prism REST interface and so, new virtual machines can't be deployed for a brief period time.
I don't know if we should consider this normal and we should assume this stop of the service during cluster upgrade or this could be improved some way. Perhaps reducing MAC cache time-out or something else. In our setup Nutanix cluster is located in one VLAN and the VDI solution is located in another VLAN, so the communication of the VDI solution with the Prism REST interface goes through routers and firewalls.
Any idea? Thanks!
