{"title":"Improving Information Technology Sustainability With Modern Tape Storage","authors":"Brad Johns","doi":"10.5594/JMI.2023.3285282","DOIUrl":"https://doi.org/10.5594/JMI.2023.3285282","url":null,"abstract":"As the world has made significant progress against the COVID-19 pandemic and world economies rebound, climate change and the broader subject of environmental, social, and governance (ESG) have become critical issues for companies worldwide. Nowhere is this experienced more than in the information technology (IT) industry, given its size and impact on consumers worldwide. The IT industry is rapidly changing with the evolution of cloud computing, artificial intelligence, big data, and the expansion of 5G networks resulting in the creation of massive quantities of information. Industry analysts estimate that the amount of data created, captured, or replicated will grow from 33 Zettabytes (ZB) in 2018 to 175 ZB by 2025. Given the focus on sustainability and the large volumes of storage devices required to store the growing quantities of data in the coming years, organizations have an opportunity to reduce their carbon footprint, improve sustainability, and reduce expenses by migrating less frequently accessed (cold data) from hard disk drive (HDD)-based storage to modern tape storage. Industry analysts believe that 60%–80% of the data stored on HDDs is cold data. Consider a hypothetical example of assessing just the impact of the storage media of keeping 100 Pbyte of information for 10 years. Compared to an HDD-only solution, an active archive that moved 60% of the HDD resident data to tape reduced carbon emissions by 58%, reduced electronic waste (eWaste) by 51%, and reduced the total cost of ownership (TCO) by 46%. In addition, if all the data is cold and is transferred to tape, carbon emissions are reduced by 97%, eWaste is decreased by 85%, and TCO is lowered by 78%. Globally, moving 60% of the HDD resident data to tape could reduce global carbon emissions by 79 million tons, making a meaningful contribution to reducing global carbon emissions. For enterprises, the financial benefits are significant enough to raise the possibility of funding the migration project entirely by the TCO savings while helping reduce global carbon emissions and eWaste.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 7","pages":"27-31"},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49962596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At the same time, M&E companies are seeking to enhance and reinvent their business using cloud computing (the on-demand delivery of compute power, database, storage, applications, and other information technology (IT) resources via the internet with pay-as-you-go pricing). Fortunately, the goals of improving sustainability and cloud adoption can be synergistic, as enhanced business efficiency via the cloud can also drive sustainability. Cloud providers, through scale and focus on innovation, can achieve higher resource utilization and greater energy efficiency than is possible for typical on-premises or collocated data centers. This article examines elements of cloud sustainability advantages and how M&E companies are working to enhance their sustainability on the cloud.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 7","pages":"20-26"},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49962597","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A large proportion of this energy is used by display devices, notably by the 1.9+ billion displays installed in consumers’ homes globally. The production of light within a display is the main reason for this energy use, independent of display technology. Reducing the global energy use of display devices by any means possible is, therefore, a topic of prime concern. Due to the very large number of displays currently in use, even small reductions per display may end up globally saving enormous amounts of energy. In this spirit, we present a video processing technique that can reduce energy requirements without altering the visual quality of the displayed material. For use cases whereby a viewer would accept a certain loss of visual quality, a user parameter could be exposed that further reduces display energy requirements.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 7","pages":"10-19"},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49962716","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To serve this fragmented market and reach a heterogeneous set of target devices, operators have to decline their services into many flavors, leading to a complex video delivery infrastructure with many redundancies. As an extensible format for encoding and packaging, the Common Media Application Format (CMAF) standard emerged in 2016 from a collaborative industry effort to simplify and streamline HTTP-based streaming media, bringing the promise of encoding and storing the media only once, as an additional step toward video streaming sustainability. From the standard publication to its fulfillment of promises, CMAF is gradually overcoming a set of technological and economic challenges. This article details the primary considerations for its implementation, including device rollout, encryption scheme and low-latency support, and also evaluates the infrastructure footprint reduction for a typical operator.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 7","pages":"39-44"},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49962725","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

At present, content providers and broadcast operators are actively involved in several research projects aiming to analyze to what extent 5G can be used for large-scale transmission of TV signals to mobile/portable devices. In this respect, this article aims at providing a general overview of the potential of 5G-broadcast technologies by means of laboratory tests, coverage simulation analysis, and field trials, with a particular eye on some deployment models that could be attractive for all the involved players in the media chain. Specifically, Radiotelevisione Italiana (RAI)-Centre for Research, Technology Innovation and Experimentation (CRITS) successfully tested 5G-broadcast technology with the coverage of the metropolitan area of Turin, and in the Aosta Valley with a single-frequency network.","PeriodicalId":49512,"journal":{"name":"SMPTE Motion Imaging Journal","volume":"132 7","pages":"45-61"},"PeriodicalIF":0.0,"publicationDate":"2023-07-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49962590","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
