DBDS:A FULLY DISTRIBUTED ALGORITHM FOR DATA MIGRATION
M Cnii · Computer Applications and Software · 2011
Data migration is a significant method for maintaining the load balance for large scale storage systems.It can greatly improve data access performance.However,most existing data migration mechanisms rely on a centralized algorithm,which seriously restricts the expandability of the system.The authors make efforts to devise a fully distributed solution called DBDS(Dimension by Dimension Spreading) to solve the data migration problem.Simulation results show DBDS enjoys both load global balance and consumption decrease during migration, so that it adapts to large scale distributed storage systems.
