Abstract
According to various illustrative embodiments of the present invention, a method for adaptive cluster input/output control includes starting a nonessential input/output operation using a first controller in a first node of a cluster, informing at least a second controller in a second node of the cluster about starting the nonessential input/output operation, and increasing the nonessential input/output operation by a predetermined utilization percentage. The method also includes waiting for a predetermined amount of time, determining whether the nonessential input/output operation has been completed, and determining whether the at least the second controller in the second node has substantially decreased performance. The method also includes decreasing the nonessential input/output operation by the predetermined utilization percentage if the nonessential input/output operation utilization percentage is greater than the predetermined utilization percentage and if the at least the second controller in the second node has substantially decreased performance, and informing the at least the second controller in the second node of the cluster about the completion of the nonessential input/output operation if the nonessential input/output operation has been completed.
