Data Storage Virtualization

"Tom Clark gives us a clear, readable guide to this emerging technology. He explains how it works, what problems it solves, and where it fits in an evolving IT infrastructure." "--Milan Merhar "Tom Clark gives us a strong overview of contemporary storage technology with storage virtualization as the central theme--a valuable work for all those seeking a broad understanding of storage in an IT infrastructure." "--David Thiel, HP Fellow and Chair of the SNIA Technical Council "Storage virtualization technology holds immense promise for streamlining data storage operations and making the unmanageable manageable. In this work, Tom Clark provides a comprehensive overview of virtualization concepts and the practical benefits customers can realize. "Storage Virtualization is recommended reading for anyone wanting to understand this next wave of innovative networked storage technology." "--John Webster, Founder and Senior Analyst, Data Mobility Group Evaluating, Planning, and Implementing High-Value Storage Virtualization Solutions Storage virtualization has come of age, offering IT professionals powerful new ways to simplify infrastructure, streamline management, improve utilization, and reduce costs. Now, the author of the best-selling storage books "IP SANs and "Designing Storage Area Networks presents an up-to-the-minute, vendor-neutral overview of storage virtualization in all its forms. Writing for IT managers, administrators, architects, analysts, consultants, and vendors, Tom Clark explains everything from the basics to the latest emerging standards. "Storage Virtualization uses realistic examples and diagrams to explain each key concept, concluding with casestudies that demonstrate real-world implementation and help you assess the technology?s business value.

"Designing Storage Area Networks, Second Edition, succinctly captures the key technologies that are driving the storage networking industry. Tom Clark's works are helping to educate the IT community to the benefits and challenges of shared storage and are recommended reading for anyone wishing to understand this exciting new technology." --Sheila Childs, VP Product Management, Legato Systems Chairperson, SNIA Fibre Channel SANs have become a mainstay at the backend of the biggest corporations on the planet. The second edition of "Designing Storage Area Networks brings the next wave of connection (IP) points and management into context, helping the user to quickly understand all the benefits before them." --Steve Duplessie, Founder and Senior Analyst, Enterprise Storage Group "Designing Storage Area Networks, Second Edition, provides a practical roadmap through the ever-changing landscape of SAN technology. The new Fibre Channel, IP, and virtualization initiatives covered in this work will enable customers to implement comprehensive shared storage solutions that reduce management overhead and cost." --John Webster, Founder and SeniorAnalyst, Data Mobility Group Storage Area Networks (SANs) are now recognized as the preferred solution for fulfilling institutions' and enterprises' critical data-storage needs. Whether powered by Fibre Channel or TCP/IP and Gigabit Ethernet technology, SANs far exceed the capabilities of traditional storage access methods. SANs are quickly becoming the solution of choice for organizations that require high-volume data-handling capacity. Written for network developers, IT consultants, administrators, and managers, this updated and greatlyexpanded edition of the best-selling "Designing Storage Area Networks goes far beyond a straight description of technical specifications and standards.

Data storage device - In computing, a data storage device—as the name implies—is a device for storing data. It usually refers to permanent (non-volatile) storage, that is, the data will remain stored when power is removed from the device; unlike semiconductor RAM.

Digital Data Storage - Digital Data Storage (DDS) is a format for storing and backing up computer data on magnetic tape that evolved from Digital Audio Tape (DAT) technology, which was originally created for CD-quality audio recording. In 1989, Sony and Hewlett Packard defined the DDS format for data storage using DAT tape cartridges.

Block size (data storage and transmission) - In computing (specifically data transmission and data storage), block size indicates a nominal size, usually expressed in bytes or bits, of a block of data. Data thus structured is said to be blocked.
