EAST FISHKILL, N.Y. -- IBM Corp. here has announced its next-generation, Unix-based server built around a dual-processor architecture equipped with copper-interconnects and silicon-on-insulator (SOI) technology.
The new Regatta server, to be shipped next year, is based on the so-called Gigaprocessor--a proprietary chip said to operate in excess of 1-GHz in performance. Consisting of more than 170 million transistors, the Gigaprocessor is optimized for both commercial and technical applications.
Each chip in the system is said to provide greater bandwidth than Sun Microsystems Inc.'s upcoming UltraSparc III processor. Bandwidth from L2 cache to the processors is in excess of 100-gigabits-per-second--the equivalent of viewing 20 full length DVDs in one second, according to IBM.
Unlike competing systems, which have fixed bus frequencies, IBM has designed Regatta so that bandwidth will increase in proportion to microprocessor frequency, ensuring future scalability. It also features a distributed switch architecture, which dramatically increases scalability in the system.
The multiple-module architecture can be grouped to form a 32-way symmetric multiprocessor (SMP) system, which can be extended even further with a non-uniform memory architecture (NUMA).
