Recently, three new articles related to the planning and deployment of Citrix XenDesktop are out to help you get a XenDesktop environment and working with VMware vSphere . Both come from Citrix Consulting Services; a planning guide incorporating Citrix Consulting best practices in the field and the laboratory, and a deployment guide with step by step instructions to help you get your basic setup and running. The third document is an article from the technical support knowledge center that describes how to solve a problem with Provisioning Server 5.6 and 6.0 when hosting target devices on vSphere 5. These documents give you lots of good information for the design and deployment, but are a subset of the documentation available on the XenDesktop design Handbook, and I encourage you to look at there. I also invite you to consult the Office Transformation Accelerator is a great tool to help you through the assessment office processing and the design and implementation phases of a project XenDesktop.
The XenDesktop Planning Guide for integration with vSphere, CTX132166, outlines the considerations and best practices for the design and implementation of a XenDesktop environment on vSphere hypervisors. It covers topics such as hardware specifications, guidelines around the vCenter and cluster configurations, networks and storage, as well as presenting some specific considerations based on our construction XenDesktop vSphere experiments in the laboratory Consulting Services. One area to have a look in the documentation covers the use of the memory management features in vSphere. There have been discussions on whether to maintain the VMware memory management functions, especially memory ballooning enabled or disabled to virtual desktops. memory bloat in vSphere includes a balloon pilot in the virtual machine that is used to artificially induce the permutation within the guest operating system if there is a problem with the memory available on the ESXi server. While this may reduce the performance of virtual machines, it is a preferable mechanism permutation compression or ESXi host level, which will have an impact on much greater performance. The best approach is to design your environment so that the memory overcommit is not a problem in operations at steady state, and let the vSphere memory management functions do their magic if there is a failure and the overcommit memory is required to handle exceptions. See also the blog of Dan Feller on the issue in general. For more details on this subject, as well as the others mentioned above, I encourage you to take a look at the whitepaper.
For the construction phase, you will find XenDesktop Deployment Guide, CTX131969, be a useful tool to assist you in your deployment activities. Assuming you have set up your ESXi / vSphere environment, the deployment guide provides step by step instructions on how to configure a complete environment XenDesktop, including the implementation of Citrix Receiver and infrastructure machine creative services, as well as advice on policy and the setting, and configuration validation. The guide also provides instructions for setting up and configuring Citrix Access Gateway Enterprise Edition and Merchandising Server to support your configuration of XenDesktop.
Using XenDesktop with Citrix Provisioning Services? There is a new technote on which describes a workaround for the implementation Provisioning Services 5.6 0r 6.0 on VMware vSphere 5. This technote, CTX131993, addresses an issue in which Windows based target machines, including virtual desktops could become unstable after an operating system reboot. The resolution of the issue is to enable "interrupt safe mode" in the bootstrap file to the target. Check the note on it contains instructions for both PXE boot from the provisioning server and when using a Boot Device Manager (BDM) ISO image.
lot to cover in one blog post, but I'm glad to see all this information become available to help you with XenDesktop deployments on vSphere. I welcome your comments.
