There’s no universal answer to prevent VDI overprovisioning, but IT should understand what resources exist and how they’re used. Virtual desktops must have access to adequate hardware resources to perform well. The problem with this, however, is that these resources come at a cost. Most organizations work to maximize their virtual desktop density per host to maximize the benefit of their hardware investment. Unfortunately, this can lead to resource overprovisioning, which negatively affects VDI performance. If taken to the extreme, resource overprovisioning can cause virtual desktops to fail.
The good news is that there are many different things that IT professionals can do to prevent overprovisioned VDI resources. A good first step is to use a performance monitoring tool to get a sense of the resources that each virtual desktop consumes. Once IT pros establish a resource consumption baseline, they can determine the maximum number of virtual desktops that each virtualization host can comfortably support. As IT determines how many virtual desktops each VDI host can handle, it is important to remember that IT can’t allocate all of the host’s resources.
