Table 1 Energy efficiency techniques, component wise taxonomy
Name of components | Techniques |
|---|---|
Processor | Speed Step Power now Cool & Quiet Demand based Switching DVS (Dynamic voltage scaling, i.e., EDP, AGGREE, A2E etc.) |
Disks | Solid states disks |
System | Low power Mode of operation Hardware level (CPU sleep/doze/busy LCD on/off) Software Level (Time Driven Sampling, Energy Driven sampling) Soft watt built upon Sim (OS) System Simulator |
Clustered system | CVS (co-ordinate voltage Scaling) |
Approaches | DPM (Dynamic Power Management) SPM (Static Power Management) Virtualization |
Networking | Energy efficient and clustering power based query optimization Sampling |
