Fault Tolerance of Clusters Configurations with Direct Connection of Storage Devices

摘要

Variants of cluster configurations with direct connection of two-input storage devices to doubled application servers in which every server is connected to two storage devices and every storage device to two servers are considered. The fault tolerance of the configurations under consideration has been analyzed. The dependence of the saving probability of the working capacity of the configurations on the number and combinatory arrangement of the failed storage devices has been stated.
