The foundational core components of NSX are divided across three different planes. The core components of a NSX deployment consist of an NSX manager, controller clusters, and hypervisor kernel modules. Each of these is crucial for your NSX deployment; however, they are decoupled to a certain extent allowing for resiliency during failure of multiple components. For example, if your controller clusters fail, your virtual machines will still be able to communicate with each other without any network disruption. You have to always ensure that NSX components are always deployed in a clustered environment so they are protected by vSphere HA.
The high-level architecture of NSX primarily describes three different planes wherein each of these core components fits in. They are the Management Plane, the Control Plane, and the Data Plane. The following...
