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.

XenServer® networking


XenServer networking isn't that much different from VMware as it also features methods to connect virtual machines to external networks, internal networks, and VLAN networks. Virtual machines have virtual network interface cards or adapters connected to networks using virtual NICs. Virtual NICs connect to vSwitches inside XenServer that connect to other virtual networks and external physical networks.

Virtual networking in XenServer is not that much different than networking in the physical realm. You assign virtual interfaces to a virtual machine and configure them with both an IP address and a MAC address–although, a MAC is assigned by default. The internal vSwitch networks your virtual machines and allows them to connect to external physical switches through the physical Ethernet adapter.

The sequence of configuring networking on XenServer is important and should match on all XenServer hosts to maintain ease of manageability. Networking is also a XenServer Pool function...
