The major challenge in designing cluster file systems is to provide high aggregate I/O bandwidth and high metadata processing throughput for applications running on large-scale cluster systems. And with the rapid increase of required data storage, how to improve access performance of a PB-scale cluster file system is also a challenging issue. In this paper, we introduce the storage space management policy for a PB-scale cluster file system. Our performance results showed that compared with Lustre and GFS, DCFS2 is able to provide comparable or even better aggregate I/O bandwidth
