Paper Abstract

According to the role of the current large-scale storage system, this paper introduces a novel metadata service strategy that separates read from write for the larger proportion of read. It centralizes control and reduces the access workload through the multi-metadata server architecture of the master/slave mode. Through the sharing of original metadata server to read the response to the large scale to reduce the load on the reading pattern to form a viable structure of the system. It not only can bring the system better scalability and usability, but can well control metadata consistency. Finally, compared to Active/Active structure, Read/Write strategy has shown a relatively good result in the aspect of the access efficiency and System costs. As a service management strategy, it effectively reduces the load of the data access of metadata service.
