Abstract
The I/O performance of internal disks in thin servers used in typical HPC Linux clusters can be inadequate for scratch I/O intensive applications in fields such as Computer Aided Engineering (CAE) and Computational Chemistry (CC). Examples of such codes are: MSC.Nastran and ABAQUS (CAE); NWChem (CC). A common approach to providing I/O facilities for applications such as these has been to add direct-attached external disk arrays on distributed servers to meet their requirements. Distributed direct-attached storage increases complexity, adds cost, reduces reliability, and creates specialized node types that are more difficult to schedule. New object-based storage techniques using high-speed cluster interconnects may be efficient for both permanent-shared and temporary-scratch storage requirements, thus improving the cost and ease of use of the compute clusters. This initial study – a collaboration between CCLRC Daresbury Laboratory and HP’s HPC Division - will measure the performance and throughput of object-based storage with an InfiniBand fabric to ascertain whether such an architecture is a viable alternative to distributed-internal or external-direct-attached storage in thin-client Linux clusters.
