....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 ....
....workloads. They also observed that it is not possible to exploit idleness in this context. Recently, Gurumurthi et al. 11] studied multi speed disks. Using simulation and synthetic workloads, they showed that multi speed disks can provide energy savings of up to 60 . Colarelli and Grunwald [7] simulated disk array energy optimizations for scientific workloads. The basic idea is to use cache disks to cache active files blocks, allowing other disks to be spun down. We have studied a different disk array energy optimization for file servers: a popularity based distribution of file data ....

....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 ....

The Massive Array of Idle Disks (MAID) [8] has been proposed as a replacement for old tape backup archives with hundreds or thousands of tapes. Because only a small part of the archive would be active at a time, the idea is to copy the required data to a set of cache disks and spin down all the other disks. All accesses to the archive ....

Colarelli and Grunwald [7] simulated disk array optimizations for scientific workloads. The basic idea is to use cache disks to cache active files blocks, allowing other disks to be spun down. The idea is similar to what we proposed at SOSP 01 [28] Our work differs from these studies in that we consider network server ....
