Validation update

For both enterprise and vendor audiences, improvements to the product make predicting and validating the performance of virtualized environments easier than ever. The update simplifies the job of locating performance bottlenecks. Version 4.1 introduces new highly realistic workloads that accurately represent real-world end user activities.

New highly realistic workloads for better predictions
Login VSI 4.0, the previous version, included three workloads. In Login VSI 4.1, we have introduced a new workload--the "Office worker"--and shifted the definition of the workloads in the previous version. The four workloads in Login VSI 4.1 include, beginning with the lightest weight users, the Task worker and Office worker for 1vCPU desktops, and the Knowledge worker and Power worker for 2vCPU desktops. These new workloads allow organizations to better match and simulate their virtual desktop usage and predict and validate the performance of constantly changing production environments. In addition, these workloads simplify integration and execution in even the most complicated virtualized environments.

Import, mix and correlate performance data from any source
Login VSI 4.1 introduces the ability to import data generated by Microsoft Windows Performance Monitor, VMware ESXtop, or any other data source in CSV format into the Login VSI Analyzer. This makes it possible to correlate performance data from the operating system, hypervisor and storage platform with VSImax. (VSImax is the measurement of maximum performance before the system experiences performance degradation). Through the built-in automatic scaling and time synchronization, the Login VSI Analyzer can easily merge performance data from different sources to easily identify and understand the performance bottleneck(s) of the individual components within the complete environment.

Improved VSImax simplifies understanding of potential bottlenecks
The new versatile VSImax measurement and calculation methodology is no longer specifically dependent on Microsoft Office Word, which gives organizations that need to test without Microsoft Office more flexibility. In addition, version 4.1 includes new VSImax measurements to help identify specific bottlenecks such as CPU or disk IO. Together with an optimized VSImax calculation methodology, the new VSImax is now more precise and delivers more powerful insights.

“Login VSI 4.1 delivers significant improvements that help organizations more easily predict and validate the performance of their constantly changing virtual desktop environments,” says Mark Plettenberg, Product Manager at Login VSI. “Because Login VSI makes large-scale performance testing easy, even organizations with the most complex virtualized environments choose Login VSI to integrate in their operational test cycles to safeguard the performance and user experience.”
