Real Time Performance Statistics in Virtual Machines For Vmware DRS

Automated management of physical resources is critical or reducing the operational costs of virtualized environments. An effective resources management solution must provides performance isolation among virtual machines, handle resource fragmentation across physical hosts and optimize scheduling for multiple resources. It must also utilize the underlying hardware infrastructure efficiently. Vmware distributed resource scheduler manages the allocation of physical resources to set of virtual machines deployed in a cluster of hosts, each running in the Vmware ESxi Hypervisor. DRS maps VMs to hosts and perform intelligent load balancing in order to improve performance and to enforce both user specified policies and system level constraints. This article mainly concentrate on maintain load balance across available hosts in a cluster, and properly utilize the overloading or underlying resources.
