VMworld 2013: Session VSVC5821 - Performance and Capacity Management of DRS Clusters

Distributed Resource Management is a feature of vSphere and it does cluster level resource management by moving virtual machines between hosts, set the resource controls on host as well as enforce business rules specified by the users. This talk focuses on how to tune DRS to ensure performance is met. This talk describes several advanced controls and how they can be used to solve performance problems like ready time and memory latency becoming high. It also describes strategies like making DRS load balance using consumed memory instead of active so that application performance is not affected by swapping or ballooning. The talk also goes into capacity management of DRS clusters and how to decide on the number of VMs to place depending on their needs.
