VMware vSphere 6.x Datacenter Design Cookbook - Second Edition

Overview of this book

VMware is the industry leader in data center virtualization. The vSphere 6.x suite of products provides a robust and resilient platform to virtualize server and application workloads. With the release of 6.x a whole range of new features has come along such as ESXi Security enhancements, fault tolerance, high availability enhancements, and virtual volumes, thus simplifying the secure management of resources, the availability of applications, and performance enhancements of workloads deployed in the virtualized datacenter. This book provides recipes to create a virtual datacenter design using the features of vSphere 6.x by guiding you through the process of identifying the design factors and applying them to the logical and physical design process. You’ll follow steps that walk you through the design process from beginning to end, right from the discovery process to creating the conceptual design; calculating the resource requirements of the logical storage, compute, and network design; mapping the logical requirements to a physical design; security design; and finally creating the design documentation. The recipes in this book provide guidance on making design decisions to ensure the successful creation, and ultimately the successful implementation, of a VMware vSphere 6.x virtual data center design.

Creating custom TCP/IP stacks


TCP/IP stacks provide flexibility in the VMkernel interface design by allowing you to apply specific DNS and default gateway configurations to a VMkernel interface on a host.

There are three preconfigured TCP/IP stacks:

  • Default TCP/IP stack: Supports management traffic

  • vMotion TCP/IP stack: Supports live migration, vMotion, of virtual machines

  • Provisioning TCP/IP stack: Supports cold migration, cloning, and snapshot creation of virtual machines

Custom TCP/IP stacks can be used to handle the network traffic of other applications and services, which may require separate DNS and default gateway configurations.

How to do it…

  1. Create a custom TCP/IP stack on an ESXi host.

  2. Configure DNS, Default Gateway, and Advanced settings on TCP/IP stack.

  3. Assign TCP/IP stack to a VMkernel adapter.

How it works…

Using TCP/IP stacks for VMkernel network traffic provides the following benefits:

  • It separates VMkernel routing tables

  • It provides a separate set of buffers and sockets

  • It isolates traffic...
