High Availability Commodity Computing - A CompactPCI-System Evaluation
نویسندگان
چکیده
This paper examines cost effective high availability systems based on standardized CompactPCI backplanes. This bus technology allows a fine-grained structural redundancy by hot-swapping peripheral boards at runtime. To quantitatively evaluate the availability of such a system, several models based on Generalized Stochastic Petri Nets have been created which take into account inter-component dependencies. We were able to show that these models lead to more realistics results than simple boolean methods which tend to be overoptimistic.
