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.

VMware virtual networking


VMware includes a virtual networking infrastructure. The virtual networking, consisting of virtual machine ports and Virtual Switches, runs in ESXi–the hypervisor. VMware virtual ports and switches support VLANs that adhere to industry standards. A virtual machine can be configured with one or more virtual Ethernet adapters, each having its own MAC and IP address. Essentially, virtual machines have the same properties as physical machines from a networking viewpoint.

VM DirectPath I/O

VM DirectPath I/O is a VMware technology that can be used by virtual machines to directly access the underlying hardware, bypassing the hypervisor. This is a big performance improvement for virtual machines that are doing a lot of I/O processing. Some virtual machine functions get disabled when using this setting, such as memory overcommitment and page sharing, so be careful when configuring it.

VMware vSphere DirectPath I/O (DPIO) is a vSphere feature that takes advantage of VT enabled...
