Abstract :
We have proposed a method replica-assisted migration that use temporally replica data in other storage nodes during executing data migration to keep both qualities of service accesses and data migration duration. However, we have not evaluated the method with real workload including update operations. In this paper, we first improve the method and evaluate an efficiency of the method under file server workloads. Base on the result of it, we also propose adaptive replica-assisted migration for reduce migration duration.
