FCCS: File Classification Caching Service Based on RAM Grid

Memory intensive applications and I/O intensive applications often suffer from the poor performance of disk swapping when memory is inadequate.RAM Grid, which combines network memory, service-oriented computing and grid computing technology, focuses on solving these problems. Being excellent at providing shared memory to improve system performance, RAM Grid can´t guarantee busy node load balance or optimal file remote cache efficiency. After studying data placement policy of large-scale network storage systems, we propose a file classification caching service (FCCS) based on RAM Grid, which promises fairness and high availability, to give a method that tries to solve those shortages. As experiment results show: FCCS improve system performance greatly.
