Overview of this book

VMware NSX is at the forefront of the software-defined networking revolution. It makes it even easier for organizations to unlock the full benefits of a software-defined data center – scalability, flexibility – while adding in vital security and automation features to keep any sysadmin happy. Software alone won’t power your business – with NSX you can use it more effectively than ever before, optimizing your resources and reducing costs. Getting started should be easy – this guide makes sure it is. It takes you through the core components of NSX, demonstrating how to set it up, customize it within your current network architecture. You’ll learn the principles of effective design, as well as some things you may need to take into consideration when you’re creating your virtual networks. We’ll also show you how to construct and maintain virtual networks, and how to deal with any tricky situations and failures. By the end, you’ll be confident you can deliver, scale and secure an exemplary virtualized network with NSX.

Controller requirements


Now that we are clear about manager deployment and design decisions, let's discuss controller requirements. NSX Controllers are also deployed as virtual appliances with default compute resources per controllers. Since we have already registered NSX Manager with virtual center and ensured that we have ports and protocols opened, let me re-emphasize once again why controllers are required:

  • VXLAN unicast and hybrid mode replication

  • Distributed logical routing

Since NSX Controllers are virtual machines with control plane intelligence, from a network requirement perspective, they need to have an IP address. However, we don't stick with the traditional method of manual or DHCP discovery processes for IP assignments. Prior to controller deployment, let's configure IP pools.

The procedure for controller IP pool creation

IP pools are used for assigning IP addresses to controllers and VXLAN Tunnel Endpoints (VTEP). I certainly love this feature, which is a less manual process. All...
