....60GXP from IBM, and Cheetah 73LP and Barracuda 180 from Seagate) where disks with different numbers of platters are rated at the same idle power. The effect of the number of platters is most significant on the energy and time overheads associated with spinning disks up and down, as suggested by [11]. In contrast, a comparison between the extremes in performance, the Ultrastar 36Z15 and the Travelstar 40GNX, shows that the laptop disk consumes only a fraction of the energy consumed by the Ultrastar disk. The power consumption of the Ultrastar disk in idle and standby states, for instance, is ....
....any case, a two threshold scheme would be straightforward to implement. In summary, our base results and parameter space study suggest that the two speed disk performs well in a wide range of scenarios. 8. RELATED WORK We are only aware of four other works on disk energy conservation for servers [12, 11, 7, 27]. Using simulation, Gurumurthi et al. 12] considered the effect of different RAID parameters on the performance and energy consumption of database servers running transaction processing workloads. They also observed that it is not possible to exploit idleness in this context. Recently, Gurumurthi ....

....the cluster to operate with fewer nodes under light load. Other efforts [3, 13, 14] tackled the high amounts of energy consumed by server CPUs. Their approach was to conserve energy by using either dynamic voltage scaling or request batching under light load. Finally, a few research efforts [6, 8, 17, 29] addressed the energy consumption in the storage subsystem of data intensive servers. We discuss these previous efforts in more detail in section 4. Even though these efforts have made important strides in conserving energy in high performance servers, there is still much to be done. Our groups ....
....is effective for all three workloads across a broad range of intensities, saving from 17 to 42 of the CPU energy. Figures 1 and 2 show the impact of these techniques on Finance and Disk Intense [14] Storage servers: Multi speed disks, MAID, and PDC. Carrera et al. 6] and Gurumurthi et al. [17] considered multi speed disks for stand alone servers. The idea behind these works is to set the speed of the disk (and, as a result, its energy consumption) dynamically, according to the load imposed on the disk. Gurumurthi et al. 17] introduced performance and power models for multi speed ....
