I'm doing my undergraduate thesis in "Power Aware Disk scheduling algorithms". I'm presently working on simulating and testing of a new algorithm. Can you tell me from where I can get traces especially of data centers consisting of several disks.?
Also, how can I know how much time and energy will it take to complete a disk request?
you can have a look at some recent USENIX conferences (HotStorage, FAST, ATC), there is some work that has been published on energy consumption of hard disk drives and SSDs. Also on HDD's energy proportionnalty. For performance simulation of disks you can use DiskSim http://www.pdl.cmu.edu/DiskSim/ but, I think there is no energy considerations. You can approximate it by looking at the disk specs.

Scheduling tools like TrueTime in MATLAB, TORSCHE Toolbox in matlab to understand the scheduling process
