DRS Insights | Sumble

What is DRS?

DRS stands for Distributed Resource Scheduler. It's a VMware vSphere feature that dynamically allocates and balances computing resources (CPU and memory) across a collection of hardware resources. DRS continuously monitors resource utilization and intelligently reallocates virtual machines to different hosts within the cluster to avoid resource contention and improve overall performance. This ensures that VMs have the resources they need, even during peak demand.
