Diab Data AB of Taby, a few miles north of Stockholm in Sweden, has launched a new Motorola 68030based processor module for creating large configurations of its DS90 Unix systems. The module operates at between 25MHz and 33MHz, has 64Kb of cache memory, and can plug into both single and multiprocessor environments. Diab’s DNIX real-time implementation of Unix System V Interface Definition has an automatic load balancing algorithm to ensure that the load is distributed across the processors, and no software changes have to be made when a new processor is installed in a system. The module can be used in all Diab’s DS90 Unix systems, which were last extended in March of last year, (CI No 890). The new module will open the way to really large Unix systems, according to Diab’s managing director Harrgot Lindmark, who says that the DS90 can handle four users in the smaller models to up to 250 users in the largest. Diab designs, manufactures and markets Unix systems on an OEM basis and now has five different models in its DS90 series. An Open Software Foundation member, it is also participating in Posix standardisation work.
