A Novel Approach to Manage A Hybrid Storage System
Journal of Communications
This paper considers the problem of how to improve the performance of hybrid storage system employing solid state disks and hard disk drives. We utilize both initial block allocation as well as migration to reach "Wardrop equilibrium", in which the response times of different devices equalize. We show that such a policy allows adaptive load balancing across devices of different performance. We also show that such a policy exploits parallelism in the storage system effectively to improvedoi:10.4304/jcm.7.7.473-483 fatcat:kt4tzgqtufedlcxzldhxkmk4tq
