Preview: ... et of experiments, no power management algorithms are used. The second part of tool demonstrates the working of DPM algorithms. The algorithms presented are Fixed Timeout, ATO1, ATO2, ATO3 and Exponential Average. Different scheduling algorithms can be used while performing simulations for each of these. For example the user can see how power management algorithm ATO1 performs if disk scheduling algorithm used is S.S.T.F or if another disk scheduling algorithm, SCAN is used. Finally, a performance comparison of any two DPM algorithms can be seen. Following are the steps to use this software Step 1: Select disk parameters Disk paraneters such as Power consumed when disk is active are used for Energy calculations and determining performance parameters like minimum sleep time required for disk to conserve energy. Disk parameters can be selected in two ways: * By selecting a disk model: When a disk modl is selected the table reflects all parameters for that disk model. * By inpu ...
