Ponachugin A.V., Sokruta V.V. The Data Storage System as a Factor in Increasing the Efficiency of Information Systems

Abstract: In their article the authors discuss ways to improve the performance of the enterprise by increasing the speed of access to data bases and overall system reliability. They study the characteristics of the data storage systems such as IOPS (the number of input-output operations per second), types of storage devices and how they connect. The authors also analyze specific scenarios of using data storate systems depending on their process connections and other basic characteristics as well as their application at the enterprise. The authors discuss further ways to expand the disk space and actions to be undertaken during when scaling of enterprise computing networks taking into account the emergence of new hybrid storage solutions based on flash memory. At the beginning of the article the authors discuss types of data storage and compares data storage sytems depending on enterprise objectives. They also study methods to select connections as well as advantages and disadvantages of each of them by studying the specifications and features of the software and hardware storage systems. The impact of IOPS on the speed of getting access to databases is also analyzed. The authors provide a table where characteristics of various data storage systems are compared. As a result of the work they identify specific patterns of using the storage system for small and medium-sized enterprises. This approach to the problem allows to create a flexible solution that does not require the complete replacement of the equipment by increasing the required disk space and connecting additional servers, thus improving the economic and process efficiency of the enterprise.
