This was a group of ultra-large general-purpose computers from Fujitsu. It was the first model group in FUJITSU's (Note 1) M-1000 Series. The five models in the FUJITSU M-1800 Model Group were announced as upper computers of the existing FACOM M-780 Model Group in September 1990. The FUJITSU M-1800 Model Group had the followingfeatures.
- (1)The group achieved the highest speed in the world by realizing the world's first 8 CPU tightly coupled multiprocessor.
- (Performance of the FUJITSU M-1800/85 was about 3 times and FACOM M-780/40
- (2)The group could flexibly handle large-scale system construction.
- Main memory capacity: Max. 2 gigabytes, System storage: 8 gigabytes, Max. number of provided channels 256
- Up to a maximum of 224 optical channels could be installed, each having a high-speed data transfer rate of 9 megabytes/second.
- (3)The group achieved higher reliability and performance via an SCMP (Note 2) configuration employing system storage.
- Up to a maximum of 16 CPUs could be connected (with the 4 cluster configuration)
- Equipped with ultra high-speed hot standby system
- (4)Single-board CPU size was reduced, and space and power savings were achieved by using the latest LSI technology and high-density multi-layer glass-ceramic boards.
- (Note 1) "FACOM", which was previously used as the brand name of Fujitsu computers, was changed to "FUJITSU".
- (Note 2)System storageCoupledMulti-Processor system
- ECL LSI with 15,000gates/chip, gate delay time 70ps
- 64Kbit RAM with 1.6ns access time + 3,500gate RAM and logic LSI
