LBVS: A Load Balancing Strategy for Virtual Storage

Cloud Storage is an important part of Cloud Computing, and it provides a way to achieve large scale storage architecture. And virtual storage is a strategy for Cloud Storage. A load balancing virtual storage strategy (LBVS) is proposed in this paper. The contribution of this strategy is that, it provides a large scale net data storage model and Storage as a Service model based on Cloud Storage. Three layers architecture is used to achieve storage virtualization, and two load balancing modules are used to balance systems load. This paper describes details of LBVS strategy, the model of virtual storage as well as how to implement the LBVS with iRODS and two load balancing algorithms.
