    Beskrivning

    This book approaches the HCI topic from the point of view that any individual working this field needs to have enough knowledge in all the different areas such as storage, storage networking, compute, virtualization, switching and routing and automation. The book will explain each area in the context of a legacy data center design, detailing the problem statement for the particular technology and how HCI solves the problem and to what extent. Equipped with such knowledge the IT professional whether at a technical or management level will be well prepared to evaluate the need to move into the HCI and to find the best approach and timeline to move from a legacy data center design to an HCI design.

    The HCI for Data center book will be the bible for IT professionals, technical and management, in all technology areas, and will guide them through the decision process to move in the HCI direction.
