Distributed Resource Scheduler
Save
Distributed Resource Scheduler (DRS) is a feature in VMware vSphere that helps to optimize the performance of virtual machines (VMs) by automatically balancing the workload across available physical resources. DRS can improve the performance and availability of VMs by ensuring that they have the resources they need to run efficiently.
Benefits of Using DRS
There are many benefits to using DRS, including:
- Improved performance: DRS can help to improve the performance of VMs by ensuring that they have the resources they need to run efficiently. This can lead to reduced latency, increased throughput, and improved overall performance.
- Increased availability: DRS can help to increase the availability of VMs by ensuring that they are always running on the most appropriate host. This can help to prevent VMs from failing due to hardware failures or other issues.
- Reduced costs: DRS can help to reduce costs by optimizing the utilization of physical resources. This can lead to reduced power consumption, reduced hardware costs, and reduced licensing costs.
How DRS Works
DRS works by monitoring the performance of VMs and the utilization of physical resources. When DRS detects that a VM is not performing optimally, it will automatically migrate the VM to a more appropriate host. DRS will also migrate VMs to prevent hosts from becoming overloaded or underutilized.
Using DRS
DRS can be used to manage the performance of VMs in a variety of ways. DRS can be configured to automatically migrate VMs based on a variety of criteria, including:
