The virtual desktop top 10 list is complete! Of course there are numerous things people can do to mess up their environment, but the 10 discussed are probably the 10 most critical. If you get them wrong, you will struggle to survive.
But the list doesn’t end there. My colleagues (Tarkan Kocoglu, Nicholas Rintalan and Doug Demskis) and I couldn’t limit ourselves to just 10 mistakes which is why we have honorable mention status to a few more items . It’s our way of keeping the top 10 list while allowing ourselves some leeway. Besides, Top 10 is so much better than Top 13 or Top 19 (top 10 has worked for David Letterman for years).
So what are these honorable mentions I speak of?
- NIC Teaming: Provisioning services streams the desktop image to the virtual desktop. Provisioning services NICs should be teamed for throughput/aggregation and not just for failover/redundancy.
- NIC Optimization: Although Provisioning services can run with the default NIC configurations, the environment can run faster with optimizations like Disable Large Send Offload
- Common Image: Reducing the number of images helps simplify management and updates as fewer image updates are required. However, using a single image across multiple physical end point platforms can become difficult to maintain. Specific hardware drivers can potentially conflict and installing multiple device drivers results in image bloat. It is often better to create different images for different hardware (not applicable if the end point is virtualized).
- VDI for Wrong Reason: Organizations should do virtual desktops because there is a business reason to provide users with a Windows XP/Windows 7 desktop interface. Without a business reason, the virtual desktop solution will be seen as extravagant and costing too much money for no value.
That completes the current Top 10 list and honorable mention for virtual desktop mistakes. If you want, you can see the entire blog series via the Top 10 Virtual Desktop Mistakes link. If you prefer documents, then sign up for the XenDesktop Design Handbook where you will get the Top 10 list plus so much more.
Enjoy and good luck
