Compaq ML350 Citrix XenDesktop architecture and implementation on ProLiant ser - Page 7

The Standard Edition includes the HP Select version of XenServer; the Advanced and Enterprise Editions include the Enterprise version of XenServer, which allows resource pooling and live migration. HP suggests that users install XenDesktop using HP PVC and either a directly connected keyboard, mouse and monitor, or use HP Integrated Lights-out 2 (iLO2). Table 1 highlights differences among the different editions of XenDesktop. Table 1. XenDesktop Edition differences Feature Core Components - Desktop Delivery Controller - Virtual Machine Infrastructure Secure Remote Access Scalability - Virtual Desktop Provisioning - Resource Pooling and XenMotion Integrated Application Delivery - XenApp for Virtual Desktops Standard √ √ Advanced √ √ √ Enterprise √ √ √ √ Citrix XenDesktop HP Standard Edition The Standard edition is available integrated at manufacturing or as a field-installed option. It offers an all-in-one solution with integrated Citrix XenServer and HP PVC for single server management. Citrix XenServer HP Standard Edition allows users to create an unlimited number of virtual machines per server, with up to 32 GB memory per virtual machine. Citrix XenServer HP Standard Edition leverages an HP ProLiant server's direct-attached storage (DAS). Customers who choose the HP BladeSystem platform can expand their storage capacity by using an SB40c storage blade, which occupies an adjacent slot in the Blade Enclosures. Citrix XenDesktop HP Advanced Edition The Advanced Edition includes all the capabilities of the Standard Edition as well as resource pooling and live migration using XenMotion. XenServer resource pools provide the ability to view multiple servers and their connected shared storage as unified resource pools, enabling flexible deployment of virtual machines based on resource needs. Live migration allows virtual machines to be moved from server to server within a XenServer resource pool without service interruption, allowing administrators to match applications with computing availability. The Advanced Edition also provides virtual desktop provisioning. XenCenter, a stand-alone application that runs on a host Windows system (Windows 2003, 2008, or XP), can be used for virtual machine management across multiple servers. XenCenter can be used to create and manage virtual machines, create resource pools and shared storage, and do live migration. Citrix XenDesktop HP Enterprise Edition Citrix XenServer HP Enterprise Edition includes all the capabilities of Citrix XenServer HP Advanced Edition plus application delivery. Application delivery provides applications and data to users in almost any location on almost any device. Centralizing applications and then virtualizing access to them allows delivery of applications as a service and provides on-demand access to users. 7
