Citrix has released an article that contains a list of known hardware-related issues encountered when using Provisioning Services. Virtual hardware issues are also included in this article. Each individual article contains specific information about the issue encountered.
I watched a webinar tonight about “Provisioning Services 6.0’s Coolest New Feature – vDisk Versioning” brought by Richard Nash. At the end of this great webinar (will post the link to the video and presentation when it comes available) Richard spent a few moments on how to update the drivers for the Provisioning Services target device.
When deploying a Provisioning Services environment, the question of where to host the vDisk store and the VHD files for target devices often arises. There are really only two primary options:
1) Block Level Storage
2) NAS Storage (CIFS or in some cases NFS)
I go into quite of a bit of detail as to why one should select block level storage and the benefits of Windows System Cache in reducing disk IOPS associated with Provisioning Server in a white paper I wrote entitled Advanced Memory and Storage Considerations for Provisioning Services. You can check out the White paper here http://support.citrix.com/article/ctx125126. I encourage everyone to first read the white paper as it will help in understanding the rest of this post.
If you don’t want your users to see the virtual disk tray notification icon then you can remove this quite easy with the following registry key:
HKLMsoftwarecitrixProvisioningServicesStatusTray Key "ShowIcon" and set the value to 0.
Caution! This fix requires you to edit the registry. Using Registry Editor incorrectly can cause serious problems that might require you to reinstall your operating system. Citrix cannot guarantee that problems resulting from the incorrect use of Registry Editor can be solved. Use Registry Editor at your own risk. Be sure to back up the registry before you edit it
Citrix has released a new best practices guide for XenApp and XenDesktop.
The foundation of any good XenDesktop or XenApp enterprise design should be adherence to a collection of best practices which are based upon knowledge gathered from previous enterprise deployments, lab validations, and lessons learned in the field. Such best practices are just a starting point for a design, as an organization’s specific design requirements will often necessitate deviation from the recommended path. By using the following recommendations as a starting point, the foundation of the design will be robust enough to support many different deployment scenarios.
This document consolidates and summarizes the best practices for XenApp and XenDesktop environments. As products evolve, best practices also change, which is why each best practice discussed in this document is associated with a specific product and version, which includes the following:
- XenDesktop 5.0, 5.5, 5.6
- XenApp 6.0, 6.5
Additional best practices are provided for those products which provide complimentary functionality to both XenDesktop and XenApp, including:
- Citrix Provisioning Services
- Citrix XenServer
- Citrix Profile Manager
- Microsoft Hyper-V
- VMware vSphere
