Provisioning Services and CIFS Stores – Tuning For Performance

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

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.

Windows Server: Proactive Windows Server Maintenance

By considering maintenance tools and techniques through a proactive lens, however, you can address potential issues before they become problems. You have considerable opportunities to save time, money and, most importantly, headaches. Continue reading “Windows Server: Proactive Windows Server Maintenance”

HyperV_Mon updated release

HyperV_Mon is a free tool for monitoring and diagnosing performance issues with Hyper-V.

After prompting from a user with a lot more processors then the test systems here, I updated the HyperV_Mon tool to handle resizing in general, and to adjust the root partition processor display.  This new version is a minor release (1.8.0).

In the works will be a version 2.0 that will look at 2008 R2 with SP1 changes.  This should come out in Q1 of next year.
