Prediction and Load Balancing System for Distributed Storage

National Data Storage is a distributed data storage system intended to provide high quality backup, archiving and data access services. These services guarantee high level of data protection as well as high performance of data storing and retrieval by using replication techniques. Monitoring and data access prediction are necessary for successful deployment of replication. Common Mass Storage System Model (CMSSM) is used to present a storage performance view of storage nodes in unified way for monitoring and prediction purposes. %for heterogenios data storage systems. In this paper some conceptual and implementation details on using CMSSM for creating a Prediction and Load Balancing Subsystem for replica management are presented. Real system test results are also shown.
