Introduction: the review is conducted in the field of modern approaches to the creation and improvement of methods for assessing the reliability of data storage systems of mobile data centers designed for the continuous provision of a high-quality set of basic and additional information services.

At the same time, services are provided to consumers in any place of their location, where typical data centers solve not only the tasks of building the information infrastructure of organizations, departments and individual large enterprises, but also tasks focused on ensuring the information security of these infrastructures. The goals and objectives of data storage systems as the technological basis of mobile data centers, the features of architectures, technologies and conditions for their construction and operation are summarized and systematized. The reliability indicators of data storage systems are studied and formulated, the role and place of reliability assessment tasks are investigated. The relevance of ensuring the accuracy and multi-criteria reliability assessment in the interests of decision-making support for the design and construction of data storage systems is justified. The subject of the study is the reliability of data storage systems as a set of interconnected components (channels, switches, blade servers, disks, disk arrays, and libraries), as well as the conditions for designing and building systems of this class that affect their reliability. Purpose: analysis of existing and development of new scientific and methodological tools and software for assessing the reliability of mobile data center data storage systems to ensure reliable and multi-criteria (taking into account the variety of components and interaction schemes) analysis of the reliability of both storage systems themselves and mobile data centers as a whole. Results: a method for analyzing the reliability of data storage systems for mobile data centers, consisting of a number of sequential steps, is proposed. The method and algorithm of its implementation are based on the logical-probabilistic approach to reliability assessment, are simple in software implementation and rational in terms of efficiency and computational complexity. Practical relevance: the presented approach allows us to formulate reliability indicators and evaluate the reliability of complex structures of data storage systems. A practical software implementation in C++ in the Visual Studio development environment has been implemented. The results of a computational experiment are obtained, which can serve as input data when making a decision on the choice of storage systems at the stages of design, project approval, replacement or update of data storage systems for mobile data centers.
