  • SOLUTION OVERVIEW EMC Celerra Multi-Path File System (MPFS) with Telestream Trafficmanager Solution
    SOLUTION OVERVIEW EMC Celerra Multi-Path File System (MPFS) with Telestream TrafficManager Solution The Big Picture: • Maximize performance – EMC’s Celerra Multi-Path File System, combines the benefits of NAS file sharing with the performance and scalability attributes of a SAN. As more Telestream TrafficManager video encoding nodes are added, more performance throughput is delivered resulting in shorter video conversion time. • Cost reduction - Moving video files from locally attached storage, to a consolidated Celerra Unified Storage solution with Telestream TrafficManager allows greater cost savings, while accelerating the application performance with Celerra MPFS. • Redundancy - MPFS-enabled storage combined with Telestream’s peer-to-peer fully redundant server arrays provide a highly resilient, fully redundant video processing platform. • Optimized environment - Consolidate redundant locally attached storage to high performance NAS thereby improving transaction throughput and reducing elapsed video encoding runtimes. • Application transparency - MPFS works seamlessly with TrafficManager, so no application changes are required. Celerra MPFS with Telestream TrafficManager The conversion of video files between different formats is a complex computing task. High Definition (HD) video files can be hundreds of gigabytes in size, and converting files for use between different systems typically requires a great deal of CPU power, RAM, and I/O throughput. Further, the speed of conversion and creation of video files is a critical metric for many media companies. Typically video production processes run against hard deadlines, and last-minute changes may require that hours of video content be converted in minutes. Telestream develops products that create and transform video files, including tools that automate video processes. The Celerra MPFS with Telestream’s TrafficManager™ solution is used to automate the video processes for video advertising and syndication content for broadcast, cable, and other media companies.

This paper is devoted to the problem of developing and application of data storage systems (DSS) and tools for managing such systems to predict failures and provide fault tolerance specifications. Nowadays DSS are widely used for collecting data in Smart Home and Smart Cites management systems. For example, large data warehouses are utilized in traffic management systems. The results of the current data storage market state analysis are shown, and the project the purpose of which is to develop a hardware and software complex to predict failures in the storage system is presented. 1 Introduction 1.1 Smart city data warehouses Nowadays there are emerging more and more examples of “smart cities” information infrastructures, both in Europe and in Russia. At the beginning of 2019, the National competence center “Smart city” was established in our country. However successful projects of “smart cities” systems management appeared earlier, one example is the data processing center for “Smart city” in Nizhny Novgorod (since 2018), the volume of data storage of which is up to 900 Petabytes [1]. Automated traffic management systems, security systems, energy systems and others are an important part of the “smart city” infrastructure. Such systems require collecting of large amounts of data in real time, therefore, the problem of * Corresponding author: [email protected] © The Authors, published by EDP Sciences.
