Abstract
A method for migrating disks includes: dividing a disk pool including a plurality of disks into a random zone and a sequential zone based on sequentiality and randomness of workloads running on the plurality of disks; monitoring a status of each disk in the disk pool based on a total cost of ownership (TCO); migrating one or more workloads of an overheated disk to an idle disk based on the status of each disk. The overheated disk has a first TCO higher than a migration threshold, and the idle disk has a second TCO lower than an idling threshold.
