Thomas P. A large quantity of digital information is being created every moment by individual and corporate consumers of IT. This information needs to be stored, protected, optimized, and managed.

Not long ago, information storage was seen as only a bunch of disks or tapes attached to the back of the computer to store data. Even today, only those in the storage industry understand the critical role that information storage technology plays in the availability, performance, integration, and optimization of the entire IT infrastructure. Over the last two decades, information storage has developed into a highly sophisticated technology, providing a variety of solutions for storing, managing, connecting, protecting, securing, sharing, and optimizing digital information.

With the exponential growth of information and the development of sophisticated products and solutions, there is also a growing need for information storage professionals. IT managers are challenged by the ongoing task of employing and developing highly skilled information storage professionals. Many leading universities and colleges have started to include storage technology courses in their regular computer technology or information technology curriculum, yet many of today s IT professionals, even those with years of experience, have not benefited from this formal education, therefore many seasoned professionals including application, systems, database, and network administrators do not share a common foundation about how storage technology affects their areas of expertise.

This book is designed and developed to enable professionals and students to achieve a comprehensive understanding of all segments of storage technology. While the product examples used in the book are from EMC Corporation, an xix 22 xx Introduction understanding of the technology concepts and principles prepare the reader to easily understand products from various technology vendors.

We have become information Data and Information dependents of the twenty-first century, living in an on-command, on-demand world that Structured and Unstructured Data means we need information when and where it is Storage Technology Architectures required. We access the Internet every day to perform searches, participate in social networking, Core Elements of a Data Center send and receive s, share pictures and videos, and scores of other applications.

Equipped Information Management with a growing number of content-generating Information Lifecycle Management devices, more information is being created by individuals than by businesses.

Information created by individuals gains value when shared with others. When created, information resides locally on devices such as cell phones, cameras, and laptops. To share this information, it needs to be uploaded via networks to data centers.

It is interesting to note that while the majority of information is created by individuals, it is stored and managed by a relatively small number of organizations. Figure depicts this virtuous cycle of information. The importance, dependency, and volume of information for the business world also continue to grow at astounding rates.

Businesses depend on fast and reliable access to information critical to their success. Some of the business applications that process information include airline reservations, telephone billing systems, e-commerce, ATMs, product designs, inventory management, archives, Web portals, patient records, credit cards, life sciences, and global capital markets.

The increasing criticality of information to the businesses has amplified the challenges in protecting and managing the data. The volume of data that 3 26 4 Section I n Storage System business must manage has driven strategies to classify data according to its value and create rules for the treatment of this data over its lifecycle.

These strategies not only provide financial and regulatory benefits at the business level, but also manageability benefits at operational levels to the organization.

Data centers now view information storage as one of their core elements, along with applications, databases, operating systems, and networks. Storage technology continues to evolve with technical advancements offering increasingly higher levels of availability, security, scalability, performance, integrity, capacity, and manageability.

It introduces the information lifecycle management ILM strategy, which aligns the information technology IT infrastructure with business priorities. Storage is a repository that enables users to store and retrieve this digital data Data Data is a collection of raw facts from which conclusions may be drawn. Handwritten letters, a printed book, a family photograph, a movie on video tape, printed and duly signed copies of mortgage papers, a bank s ledgers, and an account holder s passbooks are all examples of data.

Before the advent of computers, the procedures and methods adopted for data creation and sharing were limited to fewer forms, such as paper and film. Today, the same data can be converted into more convenient forms such as an e mail message, an e-book, a bitmapped image, or a digital movie.

This data can be generated using a computer and stored in strings of 0s and 1s, as shown in Figure Data in this form is called digital data and is accessible by the user only after it is processed by a computer.

Video Photo Book Letter Digital Data Figure Digital data With the advancement of computer and communication technologies, the rate of data generation and sharing has increased exponentially. The following is a list of some of the factors that have contributed to the growth of digital data: 28 6 Section I n Storage System Increase in data processing capabilities: Modern-day computers provide a significant increase in processing and storage capabilities. This enables the conversion of various types of content and media from conventional forms to digital formats.

Lower cost of digital storage: Technological advances and decrease in the cost of storage devices have provided low-cost solutions and encouraged the development of less expensive data storage devices.

This cost benefit has increased the rate at which data is being generated and stored. Affordable and faster communication technology: The rate of sharing digital data is now much faster than traditional approaches. A handwritten letter may take a week to reach its destination, whereas it only takes a few seconds for an e mail message to reach its recipient.

Inexpensive and easier ways to create, collect, and store all types of data, coupled with increasing individual and business needs, have led to accelerated data growth, popularly termed the data explosion.

Data has different purposes and criticality, so both individuals and businesses have contributed in varied proportions to this data explosion.

The importance and the criticality of data vary with time. Most of the data created holds significance in the short-term but becomes less valuable over time.

This governs the type of data storage solutions used. Example of Research and Business data Seismology: Involves collecting data related to various sources and parameters of earthquakes, and other relevant data that needs to be processed to derive meaningful information.

Product data: Includes data related to various aspects of a product, such as inventory, description, pricing, availability, and sales. Customer data: A combination of data related to a company s customers, such as order details, shipping addresses, and purchase history.
