Using NSX for RPC-VMware#
If you want to add individuals or groups to NSX roles, the NSX Enterprise Administrator must add them to the NSX roles through the NSX permissions section in the vSphere web client.
Rackspace configures NSX and the underlying infrastructure so that you can begin to tailor the NSX environment to your needs. Rackspace follows VMware best practices by deploying three NSX controllers for the environment. VMware only supports the use of only three controllers, even though it is possible to add and subtract controllers. If you remove or add NSX controllers, you will be outside of VMware's and Rackspace’s support requirements.
It is possible for you to create Distributed Firewall rules that could block all traffic in and out of the VMs. Take extra care when creating these types of rules in NSX.
