1. A method comprising:
- dividing a disk pool including a plurality of disks into a random zone and a sequential zone based on workload 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); and
migrating one or more workloads of an overheated disk to an idle disk based on the status of each disk;
wherein 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.

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.

11. A system comprising:
-
a plurality of disks in a disk pool, wherein the plurality of disks are divided into a first zone and a second zone based on sequentiality and randomness of workloads running on the plurality of disks; a disk status detector configured to monitor a status of each disk in the disk pool based on a total cost of ownership (TCO); and a migration manger configured to migrate one or more workloads of an overheated disk to an idle disk based on the status of each disk, wherein 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. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
