Operational Reliability Analysis of Hardware of Data Storage Systems

Abstract

The article provides definitions of a storage area network, data storage systems, a typical structural model of a storage area network, describes the problems associated with the development of storage infrastructure. An overview of major storage manufacturers and reliability indicators calculations of storage equipment are given. The study aims to analyze the reliability of the elements of disk subsystems based on operational data. The main features that corporate-level data storage systems should have are reliability and fault tolerance. Data accessibility is achieved through the full and partial backup of active storage components, as well as through advanced data integrity functions. As for indicators of reliability, we chose the failure rate and the mean time to failure. After processing the input data, the probabilities of failure-free operation, the probability of failures, the failure rate, and the failure frequency are calculated, and the graphs are plotted. The calculated values of the failure rate and the mean time to failure for the data storage elements are obtained.
