Cluster file systems: a case study

Traditional distributed file systems do not provide clusters with strict single-system image, and cannot fully meet the cluster applications requirements, such as I/O performance, scalability, reliability, and availability. COSMOS is a scalable single-image file system designed for Dawning2000 superserver, a typical cluster system. This paper discusses the essential issuesindesigningclusterfilesystems,andpresentsoursolutionstothemwithemphasisonCOSMOS'snovelty.Measurements are given to show the I/O bandwidth, scalability and overall performance of COSMOS. Based on our experience with COSMOS and initial performance measurements, we also point out the bottlenecks of the existing system and propose methods for improvement.
