VMware vSphere Performance 6.5: Designing CPU, Memory, Storage, and Networking for Performance-Intensive Workloads
It’s hard to believe how far we’ve come in the virtualization industry. What was once considered
a niche technology used only for development and testing is now used for production work-
loads and even business-critical applications. The VMware vSphere platform is capable of sup-
porting nearly any virtualized workload with very few obstacles standing in the way of close to
100 percent virtualization.
Today’s workloads are more demanding than ever before. Email servers frequently require
large amounts of memory and CPU resources in order to handle the large volume of email that
we all deal with on a daily basis. Database servers often require large amounts of memory and
storage resources, from a capacity perspective as well as performance, to meet the demands of
a business. And newer technologies, such as virtual desktop infrastructure (VDI), have intro-
duced signii cant demand for resources in vSphere environments.

This book covers the performance of your virtual infrastructure in two ways: the conceptual aspects and the practical aspects of performance.
Chapter 1: Performance Design This chapter starts by focusing on the often overlooked design considerations necessary in making today’s datacenters perform in a virtual environment. It covers principles to architect your applications using the resources already available in your datacenters while using real-world design examples.
Chapter 2: Building Your Toolbox This chapter provides an in-depth look at the useful tools in every virtualization admin’s toolbox. It covers capacity planning, performance benchmarking, simulation, and tools native to vSphere. This chapter provides insight into what these tools are used for and when to use them for troubleshooting, benchmarking, or
Chapter 3: The Test Lab In this chapter, you’ll learn when and why to build a test lab. In addition, the chapter provides insight into tools and resources available to augment a lab. The information here is a self-contained solution set for your lab and troubleshooting needs.
Chapter 4: CPU This chapter describes the basics of CPU scheduling in the ESXi platform and the hardware virtualization enhancements in today’s modern processors. It also covers the CPU sizing that’s recommended so you can provide good performance for virtual machines. Techniques for troubleshooting CPU performance problems are also covered.
Chapter 5: Memory This chapter provides an overview of the various methods that VMware ESXi uses to manage memory, including how memory is shared among workloads and reclaimed from VMs in times of contention. It also covers the memory sizing that’s recommended to provide good performance for virtual machines. Techniques for troubleshooting memory performance problems are also covered.
Chapter 6: Network This chapter provides valuable insights into designing both physical and virtual networks to support your vSphere environment, including how host selection impacts your networking options. It also covers the recommended network allocations and coni gurations you’ll need to know to provide good performance for virtual machines.
Chapter 7: Storage This chapter provides guidance on designing physical and virtual storage to meet performance demands. VMware has introduced numerous storage enhancements into the vSphere platform, and this chapter covers each of them and how they can be used to deliver good performance to virtual machines. Techniques for troubleshooting storage performance problems are also covered.
