vSphere High Performance Cookbook - Second Edition - Second Edition

By: Kevin Elder, Christopher Kusek, Prasenjit Sarkar

Overview of this book

vSphere is a mission-critical piece of software for many businesses. It is a complex tool, and incorrect design and deployment can create performance related issues that can negatively affect the business. This book is focused on solving these problems as well as providing best practices and performance-enhancing techniques. This edition is fully updated to include all the new features in version 6.5 as well as the latest tools and techniques to keep vSphere performing at its best. This book starts with interesting recipes, such as the interaction of vSphere 6.5 components with physical layers such as CPU, memory, and networking. Then we focus on DRS, resource control design, and vSphere cluster design. Next, you’ll learn about storage performance design and how it works with VMware vSphere 6.5. Moving on, you will learn about the two types of vCenter installation and the benefits of each. Lastly, the book covers performance tools that help you get the most out of your vSphere installation. By the end of this book, you will be able to identify, diagnose, and troubleshoot operational faults and critical performance issues in vSphere 6.5.

Preface

Designing a vSphere Standard Switch for load balancing and failover


The load balancing and failover policies that are chosen for the infrastructure can have an impact on the overall design. Using NIC Teaming, we can group several physical network adapters attached to a vSwitch. This grouping enables load balancing between the different physical NICs and provides fault tolerance if a network card or link failure occurs.

Network adapter teaming offers a number of available load balancing and load distribution options. Load balancing is load distribution based on the number of connections, not network traffic. In most cases, load is managed only for the outgoing traffic, and balancing is based on four different policies:

  • Route based on IP hash
  • Route based on source MAC hash
  • Route based on the originating virtual port (default)
  • Using the explicit failover order

Also, we have two network failure detection options and these are:

  • Link status only (default)
  • Beacon probing
