Scripting VDI By Day and Compute By Night

Over the weekend I finished writing a PowerCLI script to do VDI by day and compute by night. In in this post I’m going to share the script and how to set it up with you.

For those not familiar with the term VDI by day and compute by night here is my vision for it. Let’s say you have a bunch of VDI users who are structural engineers. They typically work from 8 in the morning to 5 or so at night. On their VDI desktops they have programs like like AutoCAD which require high end GPUs, but since they are using VDI they’re virtual GPUs or vGPUs. That means you have these high end GPUs that might be sitting idle for 12 to 16 hours a day and the organization spent a lot of money for those GPUs.

Now what if you could use those GPUs for something other than just engineers virtual desktops? You know, get a little more millage out of them. The R&D department keeps wanting more servers for their high performance computing (HPC) farm… What could 12 extra hours a day of GPU time coming from the Engineers idle VDI hosts do to help them?

Taking Back Resources

In this post I’m looking at reclaiming resources from virtual environments. To which you might be saying that’s simple, VMware put out a white paper on cycle harvesting. https://www.vmware.com/content/dam/digitalmarketing/vmware/en/pdf/solutions/vmware-jackson-national-life-insurance-white-paper.pdf The above paper was based on what a VMware customer did to reclaim idle CPU resources from their VDI environment. They did this by setting share …

Configuring vSwitches From an SSH Session on an ESXi Host

By Tony in VMware
July 10, 2012

Most of the time I work with SMB sized customers. Most of them don’t want or need to know the ends and outs of their vSwitch configuration (or much of the underlying configuration at all) because they don’t intend on needing to change it. If they want to modify something they will send in a …
