What is the function of VMware vSphere Storage DRS?

The function of VMware vSphere Storage DRS is to help manage storage resources dynamically. This feature automates the placement of virtual machines (VMs) on datastores based on their storage performance and space utilization. Storage DRS evaluates the resource utilization of datastores and can move VMs to balance the load, ensuring that no single datastore becomes a bottleneck while improving overall performance and availability.

By using Storage DRS, administrators can simplify storage management tasks, such as optimizing the allocation of storage resources without the need for manual intervention. This dynamic management ensures that VMs are always residing on the most appropriate storage based on current conditions, thus enhancing performance and responsiveness in a more automated and efficient manner.
