| Abstract | This paper examines the construction of a cost-effective storage cluster for an IBM Blue Gene/L supercomputer on the TeraGrid. The performance of storage clusters constructed using commodity Opteron servers and directly-attached fibre-channel RAID systems is analyzed utilizing the GPFS, Lustre, and PVFS file systems. In addition to traditional client scalability results, server scalability is also examined, identifying the number of servers required to saturate a 10 Gbps infrastructure network uplink. The results highlight test and system configurations that provide scalable throughput and identify configurations where the environment restricts scalability. Moreover, the Blue Gene/L's multiplexed I/O design introduces an additional point of contention that affects each file system to varying degrees. The paper concludes with a summary of our anticipated future work and recommendations for storage cluster deployment. |
