VMworld 2012: Session VSP1729 – Understanding Virtualized Memory Performance Management
Have you ever wondered how VMware® ESX® decides from which virtual machines to reclaim memory? Do you know the best way to tell when your host's memory is at capacity? What about how to tell when a virtual machine is starving for memory resources and experiencing poor performance? In this session, we will guide you through the complicated world of virtualized memory performance management, explaining the concept of entitlement, how it's computed and how it affects memory allocation and reclamation. We will help you better understand how memory usage patterns and interactions on the ESX Server host can affect VMware vSphere® memory metrics. Finally, we will present performance data and use that to motivate best practices around memory management to keep your datacenter running smoothly and efficiently.
