Storage Systems


Book Description

Storage Systems: Organization, Performance, Coding, Reliability and Their Data Processing was motivated by the 1988 Redundant Array of Inexpensive/Independent Disks proposal to replace large form factor mainframe disks with an array of commodity disks. Disk loads are balanced by striping data into strips—with one strip per disk— and storage reliability is enhanced via replication or erasure coding, which at best dedicates k strips per stripe to tolerate k disk failures. Flash memories have resulted in a paradigm shift with Solid State Drives (SSDs) replacing Hard Disk Drives (HDDs) for high performance applications. RAID and Flash have resulted in the emergence of new storage companies, namely EMC, NetApp, SanDisk, and Purestorage, and a multibillion-dollar storage market. Key new conferences and publications are reviewed in this book.The goal of the book is to expose students, researchers, and IT professionals to the more important developments in storage systems, while covering the evolution of storage technologies, traditional and novel databases, and novel sources of data. We describe several prototypes: FAWN at CMU, RAMCloud at Stanford, and Lightstore at MIT; Oracle's Exadata, AWS' Aurora, Alibaba's PolarDB, Fungible Data Center; and author's paper designs for cloud storage, namely heterogeneous disk arrays and hierarchical RAID. - Surveys storage technologies and lists sources of data: measurements, text, audio, images, and video - Familiarizes with paradigms to improve performance: caching, prefetching, log-structured file systems, and merge-trees (LSMs) - Describes RAID organizations and analyzes their performance and reliability - Conserves storage via data compression, deduplication, compaction, and secures data via encryption - Specifies implications of storage technologies on performance and power consumption - Exemplifies database parallelism for big data, analytics, deep learning via multicore CPUs, GPUs, FPGAs, and ASICs, e.g., Google's Tensor Processing Units




Large Energy Storage Systems Handbook


Book Description

In the current push to convert to renewable sources of energy, many issues raised years ago on the economics and the difficulties of siting energy storage are once again being raised today. When large amounts of wind, solar, and other renewable energy sources are added to existing electrical grids, efficient and manageable energy storage becomes a




Advances in Thermal Energy Storage Systems


Book Description

Thermal energy storage (TES) technologies store thermal energy (both heat and cold) for later use as required, rather than at the time of production. They are therefore important counterparts to various intermittent renewable energy generation methods and also provide a way of valorising waste process heat and reducing the energy demand of buildings. This book provides an authoritative overview of this key area. Part one reviews sensible heat storage technologies. Part two covers latent and thermochemical heat storage respectively. The final section addresses applications in heating and energy systems. - Reviews sensible heat storage technologies, including the use of water, molten salts, concrete and boreholes - Describes latent heat storage systems and thermochemical heat storage - Includes information on the monitoring and control of thermal energy storage systems, and considers their applications in residential buildings, power plants and industry




Inka Storage Systems


Book Description

Inka storage systems financed the largest prehistoric New World empire, the Inka state, which extended almost three thousand miles along the west coast of South America and into the Andean highlands. In this volume, prominent anthropologists and archaeologists explore for the first time how Inka storage was integrated into the Inka administrative system, and how Inka authorities consolidated their power by controlling access to concentrated resources. The massive wealth accumulated in Inka storehouses was legendary in sixteenth-century accounts of the Spanish invasion of the Andes. Archaeological studies reported here reveal how and why circular and rectangular Inka structures, known as qollqa, were built at high elevations where climatic conditions protected and preserved the contents. The Inkas tailored the administration of their vast economy-which was without currency-to the resources of each region and political sophistication of the local population. They filled storehouses with agricultural products, textiles and other manufactured goods, and oro from state-owned mines, through an elaborate system of taxation based on corvée labor. As organization and deployment of economic surpluses became more efficient, Inka rulers were able to tighten their control. This major contribution to Andean studies presents research from several regions and from major Inka storage archaelogical sites-Huanuco Pampa, Pumpu, Hatun Xauxa, Valle Calchaqui and Huamachuco. The discussions range from theoretical considerations of Inka political economy to excavation and analysis of individual storage structures. Inka Storage Systems is unique-focusing on storage and emphasizing archaeological data complemented by ethnohistorical interpretations. Contributors Coreen E. Chiswell, Terence N.

Energy Storage


Book Description

This book will provide the technical community with an overview of the development of new solutions and products that address key topics, including electric/hybrid vehicles, ultrafast battery charging, smart grids, renewable energy (e.g., solar and wind), peak shaving, and reduction of energy consumption. The needs for storage discussed are within the context of changes between the centralized power generation of today and the distributed utility of tomorrow, including the integration of renewable energy sources. Throughout the book, methods for quantitative and qualitative comparison of energy storage means are presented through their energy capacity as well as through their power capability for different applications. The definitions and symbols for energy density and power density are given and relate to the volume and weight of a given system or component. A relatively underdeveloped concept that is crucial to this text is known as the theory of Ragone plots. This theory makes possible the evaluation of the real amount of energy that can possibly release out of a given system, with respect to the level of power dependency chosen for the discharge process. From systems using electrochemical transformations, to classical battery energy storage elements and so-called flow batteries, to fuel cells and hydrogen storage, this book further investigates storage systems based on physical principles (e.g., gravitational potential forces, air compression, and rotational kinetic energy). This text also examines purely electrical systems such as superconductive magnets and capacitors. Another subject of analysis is the presentation of power electronic circuits and architectures that are needed for continuously controllable power flow to and from different storage means. For all systems described, the elementary principles of operation are given as well as the relationships for the quantified storage of energy. Finally, Energy Storage: Systems and Components contains multiple international case studies and a rich set of exercises that serve both students and practicing engineers.




Design and Operation of Automated Container Storage Systems


Book Description

The storage yard is the operational and geographical centre of most seaport container terminals. Therefore, it is of particular importance for the whole terminal system and plays a major role for trade and transport flows. One of the latest trends in container-storage operations is the automated Rail-Mounted-Gantry-Crane system, which offers dense stacking, and offers low labour costs. This book investigates whether the operational performance of container terminals is influenced by the design of these storage systems and to what extent the performance is affected by the terminal's framework conditions, and discusses the strategies applied for container stacking and crane scheduling. A detailed simulation model is presented to compare the performance effects of alternative storage designs, innovative planning strategies, and other influencing factors. The results have useful implications future research, practical terminal planning and optimisation.
