On Certain Approach to Assessment of Reliability for Data Center Equipment

Abstract

The article gives definitions to the data center, fault tolerance, information availability, and describes methods for estimating the cost of forced downtime for a company. The calculations for the indicators of information availability and reliability indicators are made. The aim of the study is to analyze the reliability of the data center infrastructure elements based on operation data. The main property that a data center of a high level of reliability must have is the fault tolerance. Fault tolerance of data center is assessed using information accessibility indicators. The component of the failure rate (meant time to failure) and the average repair time (mean time to recovery) are assessed during the analysis of the information availability. After processing the input data, the average information availability period and the average downtime per year are calculated.
