This paper presents a new strategy for increasing the availability of data in multi-processor, shared-nothing database machines. This technique, termed chained declustering, is demonstrated to provide superior performance in the event of failures while maintaining a very high degree of data availability. Furthermore, unlike most earlier replication strategies, the implementation of chained declustering requires no special hardware and only minimal modifications to existing software.
