Storage Devices, Local File System and Crossbar Network File System Characteristics, and 1 Terabyte File IO Benchmark on the "Numerical Simulator III"

We benchmarked a mass storage system named “CeMSS” on the “Numerical Simulator III” System. It has eighty (80) RAID-5 disk arrays and forty (40) LTO tape drives, as a storage devices, and has an HSM based local file system and crossbar network file system. We also described CeMSS design outline. In order to clear our benchmark perspective we defined “Standard IO Characteristic” and “User IO Pattern”. We recognized that the disk and tape devices of CeMSS are optimized at 2[MB] and 128+[KB] IO size. Using 16-way disks, user application programs can use over 1[GB/s] IO throughput on the NS-III. And under 80-way disk condition, CeMSS could operate a 1[TB] file within 10 minutes.
