Abstract
A process that swaps physical storage volumes. The process performs a number of simple arithmetic operations to find a seek time for B new states of a disk. The number is of order B. Each new state is related to a current state of the disk by a swap with a selected external storage volume. The process also includes swapping one of the storage volumes of the disk with the selected storage volume in response to determining that the state produced by the swap has a smallest seek or access time among the new states.
