VMs on seperate subnets

We have a UTM with 6 interfaces that go to separate subnets. Each subnet has a ToR Switch. The UTM handles the routing. We are installing a new Nutanix 4 node Block and virtualization physical servers. Assuming that we have 6 physical servers and each server is on a separate subnet, what would our network diagram look like if we included the Nutanix Block? Would we need another switch that has the 6 subnets vlanned, ie: 1 connection from the block and then based on the traffic destination send the traffic out through the vlan port to the ToR switch in the destination subnet?

Hi @Driftek,

 

Best practices is to attach the nutanix nodes in a leaf/spine method. Attach each node to two leafs. Make sure that cvm's and host's (hypervisors) are in the same, unrouted, subnet/vlan. You can add trunks to the nodes to separate virtual machines in different vlans.
