Siemens Nixdorf Informationssysteme AG is now beta testing three new models at the top end of its RM600 family, and has introduced three modules for its Transview Control Center systems and network management architecture. The new RM600 range comprises three models. The 520 incorporates from two to 12 MIPS Technologies Inc R4400 processors, has up to 2,048Mb of main memory and up to 266Gb of hard disk. Both the 530 and the 540, on the other hand, hold between two and 24 processors, have up to 4Gb of main memory, and up to 266Gb and 951Gb of hard disk respectively. Siemens Nixdorf claims that the new boxes range in performance from 4,200 to around 34,800 SPECint92. Each is claimed to support about 1,000 concurrent users, and includes an upgraded version of its 64-bit SPBus that now moves up to 300Mb of data per second, compared with the previous 224Mb per second. The machines will be marketed as database, communications and multi-user servers, ranging in price from about ?500,000 to ?2m. Meanwhile, Transview Control Center now boasts three applications: security, and distributed printing software, as well as Legato Systems Inc’s Networker back-up package. Other applications such as job scheduling, performance monitoring, and user management will follow in the fourth quarter; no prices for it.
