Abstract
Availability is one of the most important features in transaction processing systems. Fault injection is one of the effective means which can hasten availability tests. An availability evaluation toolkit is designed in this paper for IA64 system which is being widely used in transaction processing business. The availability toolkit consists of fault injection platform and availability analysis platform. A series of fault injection tools are accomplished which covers CPU faults, memory faults, disk faults, IO faults, and file system faults. Availability analysis platform is designed to calculate availability of target system and analyze sensitivity and performability as well. Experiments on a typical IA64 server are described and performed, and the experiment results validate the effectiveness of the toolkit.
