Pyramid Technology Corp yesterday duly introduced those Jolt corporate superservers previewed in CI No 2,204, calling the new line the Nile Series for public consumption. Pitched clearly at power mainframe users looking for something much cheaper, the Nile Series are symmetric multiprocessors that run the Mountain View company's DC/OSx Unix, and start with the NS150, which comes with from four to 16 150MHz R4400 RISC processors. Pyramid reckons it delivers 540 to 2,100 MIPS, with single system peak performance of 1,300 transactions per second - about twice the performance of the MIServer ES family. Cluster technology is designed to give near continuous availability during recovery after failure, and maintenance. A four-processor 150 with 256Mb memory, 10Gb disk and V.4-based DC/OSx costs UKP300,000.
