Modeling VMware ESX Server Performance

摘要

The performance implications of consolidating Windows systems under VMware ESX Server are analyzed using a simulation model. First VMware ESX Server overhead is measured based on data from Windows systems running as virtual machines under VMware ESX Server. Then a simulation model is used to estimate the contention for the physical CPUs by the virtual CPUs being dispatched from the Windows virtual machines. The simulation results are compared to some benchmark runs to validate the assumptions of the simulation model.
