Research of Scalability Model Based on Cloud Storage System

Article Preview

Abstract:

Scalability is one of the most important indicators to for performance of cloud storage system. In this paper, firstly, we pointed out limitations of three classical scalability evaluation methods with conditions of iso-speed, iso-efficiency and iso-ratio of parallel overhead to computation, when describing scalability. Then, we proposed a new scalability evaluation model which was suitable for cloud storage environment and named as EP scalability model. The EP scalability model directly reflected the performance of cloud storage system when the system scale and storage tasks expand.
