1.2.1.1 PRIMEQUEST-dedicated chipset
The chipset is an LSI device that controls data transfer among CPUs, memory, and
IO_Units.
The PRIMEQUEST-series machines contain this new chipset that has been developed
by Fujitsu for improved performance and increased reliability.
The following three achievements are made by the PRIMEQUEST-dedicated chipset:
• Large-scale SMP
The high-speed memory access technology in the chipset suppresses deteriorations in
performance in a large-scale SMP configuration, resulting in a high-performance
system with high scalability.
• System Mirror
The chipset supports dual reading/writing of memory and synchronizes duplication of
system interconnects. System Mirror, one of the new technologies of the
PRIMEQUEST-series machines, is thus implemented.
• High reliability of the internal chipset
By using highly reliable technologies (e.g., duplicated internal chipset) originally
developed for mainframes, the chipset has greatly increased reliability.
