Overview

VMware vSphere is the key virtualization technology in today's market. vSphere is a complex tool and incorrect design and deployment can create performance-related problems. vSphere High Performance Cookbook is focused on solving those problems as well as providing best practices and performance-enhancing techniques.

vSphere High Performance Cookbook offers a comprehensive understanding of the different components of vSphere and the interaction of these components with the physical layer which includes the CPU, memory, network, and storage. If you want to improve or troubleshoot vSphere performance then this book is for you!

vSphere High Performance Cookbook will teach you how to tune and grow a VMware vSphere 5 infrastructure. This book focuses on tuning, optimizing, and scaling the infrastructure using the vSphere Client graphical user interface. This book will enable the reader with the knowledge, skills, and abilities to build and run a high-performing VMware vSphere virtual infrastructure.

You will learn how to configure and manage ESXi CPU, memory, networking, and storage for sophisticated, enterprise-scale environments. You will also learn how to manage changes to the vSphere environment and optimize the performance of all vSphere components.

This book also focuses on high value and often overlooked performance-related topics such as NUMA Aware CPU Scheduler, VMM Scheduler, Core Sharing, the Virtual Memory Reclamation technique, Checksum offloading, VM DirectPath I/O, queuing on storage array, command queuing, vCenter Server design, and virtual machine and application tuning.

By the end of this book you will be able to identify, diagnose, and troubleshoot operational faults and critical performance issues in vSphere.

    Indeed, you should probably be a VMware administrator, or perhap

    Indeed, you should probably be a VMware administrator, or perhaps one in training, to get the most out of this book. The recipes for improved performance presuppose that you are already running VMware and are cognisant of the basics of doing so.

    Chapter 1 is interesting in part because of a good discussion of virtual CPUs and subtopics like the distinction between translation and emulation. I often regard those as synonymous, and perhaps you do also. But the author reminds us that emulation maps from one hardware architecture to another, while translation maps from a full starting instruction set to a subset of instructions that can be safely run. We see that VMware translates from the x86 family. Which dominates the desktop mostly through all those Microsoft-running personal computers. But also many linux machines run linux atop x86. So this is the most common case for VMware to handle.

    However, the book also describes albeit briefly both Intel and AMD virtualisation methods. Good to see that AMD is staying in the game. Chapter 1 explains several metrics you can measure in VMware, while cautioning that you must expect an imperfect map from these to user expectations in your firm. So at a basic level, the CPU performance recipes in this chapter can be your most useful methods for doing performance optimisation.

    Another chapter then moves from the CPU to the memory. Logical enough. Here, you learn how crucial it can be to reduce swapping from memory to disk, because of the horrendous disparities in access times [as much as 5 orders of magnitude]. By using the recipes in this chapter to regulate the memory use, you might be able to avoid having to purchase more memory. The latter is sometimes the simplest default answer to swapping or thrashing. But the book suggests alternatives.
