In Huawei FusionCompute, what must DPM rely on before it can be used?

In Huawei FusionCompute, DPM (Dynamic Power Management) relies on DRS (Distributed Resource Scheduler) before it can be effectively utilized. DRS is responsible for managing resource allocation across the compute resources in a virtualized environment. It ensures that workloads are balanced and optimally allocated, which is essential for DPM to function effectively.

DPM works by monitoring the resource utilization within a cluster and making decisions about when to power down physical servers to save energy while also maintaining performance. Without the dynamic resource scheduling provided by DRS, DPM would not have the necessary data or framework to make informed decisions about resource management and power savings. DPM uses the information collected by DRS to ensure that sufficient resources are available to meet demand, even when some servers are powered down. Thus, for DPM to operate successfully, it fundamentally relies on the scheduling and resource balancing capabilities provided by DRS.
