The article describes in detail the purpose of modern data processing centers, provides data center definitions, fault tolerance, information availability, failures, describes methods for estimating the cost of forced downtime for a company, calculates information availability and reliability indicators. indicators. The purpose of this work is to analyze the reliability of data center infrastructure elements based on operational data. The main feature of the fact that the data center must have a high level of reliability is fault tolerance. Resilience of the data center is assessed using information availability indicators. When analyzing the availability of information, the failure rates of the components and the average repair time were estimated, which are determined in terms of the average uptime and average recovery time. As indicators of reliability, we chose the probability of failure-free operation and the average time to failure. After processing the input data, the period of availability of information was calculated, the average period of inactivity for the year. Thus, from the obtained results, the following conclusion was made that the data center under study has a high level of reliability and, therefore, has all the necessary disaster recovery systems.
