Evaluation of Design Alternatives for a Cluster File System
Murthy Devarakonda, Ajay Mohindra, Jill Simoneaux, William H. Tetzlaff, IBM T. J. Watson Research Center
Based on implementation experience and measurements, this paper presents an evaluation of design alternatives to a cluster file system. The file system is targeted for IBM cluster systems, Scalable POWERparallel and AIX HACMP/600. We considered a shared disk approach where serialized, multiple instances of a single-system file system directly access file data as disk blocks, and a shared file system approach which is the conventional method of distributing file system function between a client and a server. We conclude that the shared disk approach suffers formt eh difficulties of metadata serialization, pooor write-sharing performance, and read throughput.
