Abstract :
Although effective techniques exist for tackling disk power for laptops and workstations, applying them in a server environment presents a considerable challenge, especially under stringent performance requirements. Using a dynamic rotations per minute approach to speed control in server disk arrays can provide significant savings in I/O system power consumption without lessening performance.
