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 data plane

Deploying the data plane involves preparing the ESXi hosts that enable them to participate in network virtualization. To prepare your environment for network virtualization, network components must be installed on a per-cluster basis. Any new hypervisors added to this cluster will automatically be prepared for network virtualization. After the network virtualization software (installed as a VIB) is installed, the logical firewall is enabled on that cluster. One important prerequisite is to ensure all hosts in the cluster are part of the distributed virtual switch:

To prepare a cluster go to the Networking & Security | Installation | Host Preparation tab:

Pick your cluster that you want to prepare for NSX component installation on the host. Hover over the Installation Status column and you will find the Install option:
