Eau Claire, Wisconsin-based Chen Systems Inc has duly launched its promised 133MHz two-to-eight-way Pentium-based CS-1000 Series symmetric multiprocessing servers, claiming that they offer a set of parallel architecture and system management features until now found only in mainframes, supercomputers, and highly specialised machines. My plan when I founded this company, said Dr Chen, was to put everything I learned while designing supercomputers about parallelism, fast input-output, sustained performance, and system availability into a high-performance server based on off-the-shelf technology. The CS-1000’s bus provides peak throughput of 400M-bytes per second and supports two PCI buses, up to 1Gb memory and 1.7Tb disk. The AcceleRAID parallel disk input-output system provides two disk controllers, each providing four parallel fast-wide SCSI channels and each capable of sustaining more than eight parallel disk input-output operations concurrently with the CPU operations. Chen says that the CS-1000/10 server, which runs UnixWare 2 and includes Somerset, New Jersey-based Programmed Logic Corp’s High Throughput File System, won the best price-performance on the AIM Shared System Mix performance tests. Prices start at a hefty $75,000 for a two-way system.
