Abstract :
The requirements for highly available computer systems have evolved over time. In a commercial environment end-users and consumers do not tolerate systems that are unavailable when needed. This paper describes and evaluates the High Availability Cluster Multi-Processing (HACMP/6000) product. HACMP/6000 is a clustering solution for high availability distributed systems. Our approach in showing the effectiveness of HACMP/6000 is both qualitative and quantitative. We use availability analysis as a means of our quantitative analysis. Availability analysis is undertaken using a state-of-the-art availability analysis tool-System Availability Estimator (SAVE). Results obtained from the analysis are used for comparison with a non-HACMP/6000 system
