NEC designed the NX7000/P590 UNIX server and began rolling it out in May 1997. It could be fitted with up to eight PA-8000 (180 MHz) processors and was noteworthy because of its I/O expandability. The NX7000/P590 was used to construct fast, highly reliable systems by taking advantage of the performance afforded by its eight-way SMP architecture and NEC' fault-tolerant technologies accumulated through the company' experience with mainframes.
The server could be expanded to eight 64-bit PA-8000 processors, clocked at 180 MHz, and featured a new system bus architecture that achieved throughputs as high as 1.28 GB/s. The server' high reliability was the result of incorporating error-correcting codes (ECC). The memory modules could be expanded to 8 GB with up to 16-way interleaving and the modules' reliability was increased with ECC. In terms of availability, the NX7000/P590 outperformed its predecessors because of its redundant power supply, its hot-pluggable internal disk units and fans, and its service processor, which made it possible to automatically acquire fault information, identify and isolate fault locations, and automatically restart the system.
