Pyramid Technology Inc has replaced its Corporate MIServer line with the new T Series line of database servers, claiming the lead in transactions per second performance over rivals such as Sequent Computer, IBM and DEC. The MIServer Turbo Series uses the same 14 MIPS CMOS RISC processor as the earlier machines, but increases throughput by up to 40% by using a new memory management system providing 1Mb cache for each processor, and a dual caching system for data and instructions. Pyramid has also increased main memory capacity to 512Mb and added 128Mb memory arrays using 4Mb DRAMS to further offload input-output from the CPU. It claims a 12 processor system was benchmarked at 250 transactions per second running the Oracle Banking Benchmark, comparing to 124 TPS on a Sequent, 50 TPS on an IBM 3090 and 49 TPS on a DEC VAX. And Pyramid has added an enhanced self-diagnostics system to improve reliability. There are four packages available: the two processor MIS 12T/50 has 64Mb memory and 10Gb storage and is UKP531,250: then comes a four processor 12T/100, six processor 12T/150, and a 10 processor 12T/200 with 512Mb memory and 30Gb disk space for UKP1,700,000 – the numberings relate to the TPS ratings.
