Calculating Maximum Virtual Desktop Capacity – VSImax Explained
In virtualized desktop environments, knowing how many users any given configuration can support is critical to maintaining uptime, delivering on SLAs and providing a great desktop experience for end users. Load testing and stress testing virtualized desktop environments is a key use case for Login VSI. After running a Login VSI load test, the Analyzer provides information on the maximum capacity of your virtualized desktop environment with a number–VSImax. But you may ask how this number is actually calculated. This is an excellent question because understanding what goes into a VSImax can help you to better interpret the test results in the Login VSI Analyzer.
