Optimizing Citrix?? XenDesktop?? for High Performance

By: Craig Thomas Ellrod

Overview of this book

Citrix XenDesktop is a suite of desktop virtualization tools designed to provide users with fast and convenient access to their Windows desktops and applications through any device. Virtual desktops mean that rather than setting up hundreds or thousands of individual computers in an enterprise, companies can instead opt to create servers with large amounts of memory, disk, and processing resources, and use virtualization to offer these resources to end users. The result of this is that users are provided with an experience that appears to be identical to having an individual desktop PC. Each user has some disk space, processor time, and memory allocated to them, as though it is present on their own physical machine, when in reality, the resources are physically present on a centralized server. This book starts by answering the basic questions you need to ask when considering XenDesktop, followed by methods of how you can properly size your server infrastructure for XenDesktop. You’ll discover how to optimize the virtual machines used in XenDesktop, how to optimize your network for XenDesktop, and how to optimize the hypervisor and the cloud. You’ll also learn how to monitor XenDesktop to maximize performance. By the end of the book, you will be able to plan, design, build, and deploy high performance XenDesktop Virtualization systems in enterprises. You will also know how to monitor and maintain your systems to ensure smooth operation.

Chapter 2. Sizing

In the first chapter, we started with defining some basic XenDesktop architectures, terminology, concepts, and components. Now, we'll learn how to size them. While none of the XenDesktop site is the same, you need to start somewhere. That somewhere is here, where we give you some tools to help you keep your deployment within the bounds of comprehension. Sizing the environment is critical to understanding where the different components will be placed and how to prepare to build them. As your site grows, performance will be impacted if it isn't designed well, so getting the blueprint right the first time is critical. One thing we often say in our business is measure twice, and cut once. What that means is do your planning and scoping in great analysis, and do it more than once before you start ordering and deploying. In this chapter, we will cover the following:

  • System requirements

  • Hypervisor hosts

  • XenDesktop sizing

Tip

Tribal Knowledge indicates you should size for "peak" usage...
