VMware DRS (Distributed Resource Scheduler)
VMware DRS (Distributed Resource Scheduler) is a utility that balances computing workloads with available resources in a virtualized environment. The utility is part of a virtualization suite called VMware Infrastructure 3.
With VMware DRS, users define the rules for allocation of physical resources among virtual machines. The utility can be configured for manual or automatic control. Resource pools can be easily added, removed or reorganized. If desired, resource pools can be isolated between different business units. If the workload on one or more virtual machines drastically changes, VMware DRS redistributes the virtual machines among the physical servers. If the overall workload decreases, some of the physical servers can be temporarily powered-down and the workload consolidated.
Other features of VMware DRS include:
Dedicated infrastructures for individual business units
Centralized control of hardware parameters
Continuous monitoring of hardware utilization
Optimization of the use of hardware resources as conditions change
Prioritization of resources according to application importance
Downtime-free server maintenance
Optimization of energy efficiency
Reduction of cooling costs.
VMware, a subsidiary of EMC Corporation, is headquartered in Palo Alto, California and provides virtualization software for x86-compatible computers.
