2 Lenovo: Laptop-level PM

3 VMware

4 Host Power Management 1.C-states to lower idle power 2.P-states to lower active power (+TurboBoost)

5 Host Power Management

6 Distributed Resource Scheduler Migrate VMs for priority and to maintain minimum resource requirements

7 Distributed Resource Scheduler

8 Distributed Power Management Migrate VMs for host power savings Requires WOL ! Different from HPM (local vs. distributed)

9 Distributed Power Management

10 HPM vs. DPM 8 hosts. 30min idle, 30min load, 30min idle
