Attempt to Utilize Surplus Storage Capacity as Distributed Storage

Abstract

High-performance computers have spread at a lower cost than in the past by technological advancement. Thus, the performance of computers may be excessive for its usage. In this case, resources of computers such as CPU, memory, and storage are not utilized fully and resulting in an idle state; that is, these idle resources are wasted despite use-value. We should utilize them effectively. For this reason, we attempt to utilize surplus storage capacity, one of the idle resources, as distributed storage. In this paper, we design a distributed storage using surplus storage capacity by considering characteristics of surplus storage capacity and computers with its capacity.
