    Hello, habrozhiteli! With the help of EMC, we released a book that (which does not often happen with translated books) received the stamp of a textbook:

    imageIn the several years that have passed since the release of the first edition, the world known to us has undergone incredible changes. We live in the era of digital technology, when the amount of information available in the world more than doubles in two years, and in the next decade IT departments will have to cope with information volumes that have increased by more than 50 times, and this despite the fact that the number of specialists in information technology will increase only one and a half times. Now virtualization and cloud computing for enterprises is no longer just one of the possible options, but an imperative for survival in the market. And the so-called big data provides organizations with new, highly effective analysis capabilities,

    With the advent of cloud computing, completely new technologies, computer models and disciplines have appeared that have greatly changed the ways of building and running information technologies, as well as managing them. To keep up with these transformations, new specialties have been introduced, such as the technologist and cloud architect.

    The book will open up new perspectives for you and allow you to understand new technologies and skills that are in demand today for the development, implementation, optimization and use of virtualized infrastructures, as well as managing them in order to achieve the benefits that a business can get from the use of cloud technologies.


    In the two short years since the release of the first edition of the book, the world we know has undergone incredible changes. We live in the era of digital technology, when the amount of information available in the world more than doubles in two years, and in the next decade IT departments will have to cope with information volumes that have increased by more than 50 times, and this despite the fact that the number of specialists in the field of information technology will increase by only one and a half times (according to a report presented in June 2011 by the analytical company IDC "Research into the Digital Universe", the preparation of which was sponsored by EMC). Now virtualization and cloud computing for enterprises is no longer just one of the possible options, but an imperative for survival in the market. And so-called big data provides organizations with new,

    As a result of all this, the information technology industry is undergoing tremendous changes. With the advent of cloud computing, completely new technologies, computer models and disciplines have appeared that have greatly changed the ways of building and running information technologies, as well as managing them. To keep up with these transformations, new specialties have been introduced, such as the technologist and cloud architect. Organizations working in the field of information technology have evolved from infrastructure operators of the operations department, performing the task of maintaining equipment operability, into key strategic figures in organizing a business specializing in providing information technology in the form of services.

    All these changes required new key skills in the IT organization, a new way of technological thinking in the context of business requirements and strategic goals, and even a new organizational structure of the data center. Professionals in the field of information storage and management should replenish existing knowledge and develop additional skills in the field of those technologies that play the most important role in successfully mastering a complex long-term path to the clouds, that is, to master, in particular, virtualization technologies, converged networks, information security, data protection, and charging for data storage and analysis services.

    We revised this book to reveal new perspectives and give you the opportunity to deeply penetrate the essence of the new technologies and skills that are in demand today to develop, implement, optimize and use virtualized infrastructures, as well as manage them in order to achieve the benefits that business can get from the use of cloud technology. You will learn on the basis of the knowledge that highly qualified EMC specialists who have the richest experience in training, certification of experts and practical work in this industry will share with you.

    Whoever you are - a professional in the field of information storage and management, who is in the process of virtualizing your data center or creating a reliable cloud infrastructure, or as a simple person interested in learning the concepts and principles of new paradigms - the improvement of your skills has not yet acquired a similar degree of importance. Accelerating the process of self-improvement with the help of this book and taking advantage of training and passing the new qualification certification that is already available to you, you can help close the critical shortage of qualified specialists in the information industry, gain career opportunities and begin to fully contribute to the successful expansion of your company and Her achievement of high rates of stability and profitability.

    There are still enough problems in this area, but according to your affairs you will be rewarded. Nelson Mandela once said: "Education is the most powerful weapon with which you can change the world." I hope that this book will become one of the main sources of your IT education and professional development no matter what role you are currently in, and that you will certainly take the opportunity to change yourself and help make this world a better place.

    Introduction

    Information storage is an essential component of information technology. Every moment, individuals and organizations create huge amounts of digital information that must be stored, protected, optimized and managed in a classic, virtualized and rapidly evolving cloud environment.

    Not so long ago, information storages were presented only in the form of magnetic disk drives or tapes connected to a computer for the purpose of storing data. Even today, the crucial role played by information storage technology in achieving high levels of accessibility, performance, integration and optimization of the entire IT infrastructure is understood only by specialists in the field of data storage industry. Over the past decade, information storage has evolved into a very sophisticated technology that provides a variety of digital information solutions related to storage, management, connection, protection, security, sharing and optimization.

    The widespread adoption of virtualization, the advent of cloud computing, the multiple annual growth of data volumes and the availability of diverse
    types and sources of data - all these factors have made modern data storage technologies even more important and relevant for the successful operation of both commercial and any other organizations. The most acute compared to previous times, the leaders of the IT industry faced the problem of hiring and training highly qualified technical specialists in the field of data storage, well versed in the work of classic, virtualized and cloud environments.

    Many leading universities and colleges now include courses in the study of data storage technologies in their programs of studying ordinary computer or information technologies, since until now IT professionals, even those with many years of work experience, have not received any significant formal training advantages. Therefore, many experienced professionals, including administrators of applications, systems, databases and networks, do not have a common opinion about the impact of data storage technology on their areas of activity.

    This book was conceived and created in order to help professionals and students gain a deep understanding of all the components of data storage technology. Although the examples of industrial designs used in this book relate to EMC Corporation products, an understanding of technological concepts and principles will prepare you for easy adoption of technical products from various suppliers.

    The book contains 15 chapters, summarized in five sections. Topics are outlined by increasing complexity of the material, all subsequent topics should be studied after mastering the previous ones. Section I introduces the concepts of virtualization and cloud infrastructure, which are then referred to throughout the book to provide an overview of storage technologies in the context of a traditional or classic environment, a virtualized environment, and a rapidly evolving cloud environment.

    Section I “Storage Systems”. The four chapters of this section discuss the problems of the information boom and changes in the nature of stored information, give definitions of the data storage system and the environment of the data center, provide an overview of the development of data storage technology and provide an introduction to intelligent data storage systems. In addition, the concepts of virtualization and cloud computing are introduced in this section.

    Section II "Network Storage Technologies". The four chapters in this section discuss a fiber-based storage area network (FC-SAN), an Internet Protocol based storage area network (IP SAN), and network storage devices - Network -attached storage (NAS), object-based storage technologies and unified data storage. In addition, this section discusses the concepts of storage associations and converged networks (FCoE).

    Section III “Backup, Archiving and Replication”. The four chapters in this section discuss business continuity, backing up and restoring data, data deduplication, data archiving, and local and remote data replication in both classic and virtualized environments.

    Section IV “Cloud Computing” . The only chapter in this section discusses cloud computing, including its infrastructure, service models, deployment options, and factors that determine how to move to using cloud computing.

    Section V “Securing and Managing Storage Infrastructure”. The two chapters in this section discuss the security of the storage infrastructure, monitoring and managing the infrastructure, including security and management issues in virtualized and cloud environments.
