Concurrent Computer Corp is doing a splendid job of disguising the origins of its new line of fault-tolerant real-time Unix servers originally promised for April (CI No 1,379). Announced from the old Masscomp facilities in Westford, Massachusetts, the AP/Servers comprise the complex instruction set AP/600 series for input-output-intensive work, the AP/800 series compute-intensive RISC system; and the AP/320 series communications, terminal interface and database server. The company does not identify the processors, but it appears that the 800s are derived from the new 8000 machines based on the R3000 RISC from MIPS Computer Systems Inc – which uses boards supplied by Silicon Graphics Inc; the 600 from the Motorola 68030-based 6000 systems, and the 320 from Concurrent’s proprietary 3200 family minicomputer line. Both the AP/600 and 800 series run under the company’s RTU real-time Unix, and all three offer selectable levels of fault-tolerance, with support for mirrored disks. The databases supported include Ingres, the company’s own Reliance Plus, Oracle, Informix and Unify. Models of the AP/Server line support all TCP/IP, Network File System, Ethernet, DECnet, X25, Systems Network Architecture and Open Systems Interconnection. The multiprocessor AP/Servers support optional integral vector and floating point accelerators, and prices range from $48,000 for the base system, to $320,000 for a fully configured system. The AP/600 is available now, the AP/800 is expected in August, the AP/320 in December.
