This design uses two separate NSX instances per region. One instance is tied to the Management vCenter Server, and the other instance is tied to the Compute vCenter Server. Deploy and configure the NSX instance for the management cluster in Region B.

1

For this implementation NSX Manager and vCenter Server have a one-to-one relationship. For every instance of NSX Manager, there is one connected vCenter Server. 

2

You join the secondary NSX instance in Region B to the respective primary instance in Region A.

3

NSX kernel modules packaged in VIB files run within the hypervisor kernel and provide services such as distributed routing, distributed firewall, and VXLAN bridging capabilities. You must install the NSX kernel modules on the management cluster ESXi hosts to be able to use NSX.

4

After all the deployment tasks are ready, you must configure the NSX logical network.

5

When an authorized change is made to a host, the Host Profile must be updated to reflect the changes.

6

You configure load balancing for all services and components related to Platform Services Controllers (PSC) using an NSX Edge load balancer.

7

NSX for vSphere creates a network virtualization layer on top of which all virtual networks are created. This layer is an abstraction between the physical and virtual networks. You configure NSX dynamic routing within the management cluster, deploying two NSX Edge devices and configure a Universal Distributed Logical Router (UDLR).

8

After deploying the vCenter Server you must add it to the exclusion list. The default rule in Region b also needs to be changed to deny.

9

Test the configuration of the NSX logical network using a ping test. A ping test checks if two hosts in a network can reach each other.

10

After the clusters are fully configured in Region A and Region B, verify that the network connectivity between them works as expected.

11

Deploy the application virtual networks for the region.

12

Deploy a load balancer for use by management applications connected to the application virtual network Mgmt-xRegion01-VXLAN.
