A Survey on Research Trends in Disk Scheduling Algorithms

In operating system, Disk scheduling is the process by which a storage management decides the order that I/O operations are submitted to storage volumes. Disk Scheduling Algorithms are used to decide which of the I/O request have to be served next so that the total head movements and the total seek time of any I/O request could be reduced. Modern disk drives have the ability to queue incoming read and write requests and to service them in an out of order fashion and Disk scheduling involves a careful examination of pending requests to determine the most efficient way to service the requests. In this paper we collected and integrated various researches done in the field of disk scheduling and Disk management, so that this effort can be helpful for new researches to find out the future trend in the same field.
