Title
An Architecture for High Availability Multi-user Systems
Abstract
This paper describes fault tolerance features of a multiprocessor system called SPAX (Scalable Parallel Architecture based on X-bar network). It aims at a cost-effective reliable multiprocessor system for both scientific and business applications. The system can be composed of up to sixteen clusters. Each cluster consists of eight nodes which can be any combination of processing nodes, input/output nodes and communication nodes. The system is designed to eliminate potential single-points of failures such as loss of a processor, loss of a network, or loss of a disk drive. Xcent-Net, which is a duplicated hierarchical crossbar interconnection network built into the system, supports dual paths to every node with high bandwidth and with low latency. Each node is designed to support multi-level fault tolerance enabling a user to choose the level of fault tolerance with a possible resource or performance penalty. The system has been implemented at ETRI.
