Overview of this book

VMware NSX is a platform for the software-defined data center. It allows complex networking topologies to be deployed programmatically in seconds. SDNs allow ease of deployment, management, and automation in deploying and maintaining new networks while reducing and in some cases completely eliminating the need to deploy traditional networks. The book allows you a thorough understanding of implementing Software defined networks using VMware’s NSX. You will come across the best practices for installing and configuring NSX to setup your environment. Then you will get a brief overview of the NSX Core Components NSX’s basic architecture. Once you are familiar with everything, you will get to know how to deploy various NSX features. Furthermore, you will understand how to manage and monitor NSX and its associated services and features. In addition to this, you will also explore the best practices for NSX deployments. By the end of the book, you will be able to deploy Vmware NSX in your own environment with ease. This book can come handy if you are preparing for VMware NSX certification.

Deploying the control plane (Controller Virtual Machines)

The control plane consists of the controller nodes that eliminate the need for multicast support from the physical network infrastructure to manage VXLAN-based logical switches. A minimum of three controller virtual machines is required for high availability.

To deploy controller nodes, go to Networking & Security | Installation, and under the Management tab click the + symbol in the NSX Controller nodes section:


VMware recommends that you add three controllers for scale and redundancy. Controller cluster virtual machines employ a slicing mechanism, that is, all of them are active at any given time. If a controller virtual machine fails, the tasks failover to the other active peers. This is done by means of a master controller that is elected by means of a majority vote. To maintain this majority it is always recommended to deploy controller cluster virtual machines in odd numbers. Ensure there is no resource contention in the...
