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 the host for a highly available and high-performance storage


VMware ESXi enables multiple hosts to share the same physical storage through its optimized storage stack and VMware VMFS-distributed filesystem. Centralized storage of VMs can be accomplished using VMFS and/or NFS. Centralized storage enables virtualization capabilities, such as VMware vMotion, VMware Distributed Resource Scheduler (DRS), and VMware High Availability.

Several factors have an effect on storage performance:

  • Storage protocols
  • Proper configuration of your host device and storage devices
  • Load balancing across available storage processors
  • Storage queues

Getting ready

To step through this recipe, you will need one or more running ESXi Servers, an HBA card, an NIC card, and a Fibre Channel (FC) or an iSCSI storage. No other prerequisites are required.

How to do it...

High availability requires at least two HBA connections to provide redundant paths to the SAN or storage system.

Follow these steps to design high-performing...
