A good book for blade server and virtualization.
Preface:
Technology changes over the last 30 years have come in many shapes and
sizes. Some have dramatically altered the face of computing, while others were
a flash in the pan. This book focuses on two technologies (one mostly hardware
and one mostly software) that are rapidly becoming key building blocks
for the next generation of data centers. Blade servers and virtualization, working
together, provide the flexibility, high availability, and manageability to
enable utility computing, where computing resources are provisioned as
needed to deliver services on demand to users anywhere, anytime.
Blade server systems offer a highly modular, prewired, ultrahigh-density
form factor for servers in the data center. With a design that allows shared
redundant components such as power and cooling, network switches, and management
modules, blade servers help reduce the number of components in the
data center, as well as significantly increase the computing power per footprint.
Virtualization also offers both space savings and a reduction in the number
of physical components by allowing multiple servers to be consolidated as virtual
servers onto a single physical server. Virtualization eliminates the problem
of large numbers of highly underutilized servers, and the space,
management, power, and cooling that they require.
Both of these technologies are available in many forms from a variety of vendors,
including major systems and software vendors as well as a number of
innovative start-ups. Both have been successfully implemented in user environments
ranging from small-medium businesses (SMB) to some of the largest
enterprise data centers in the world.
This book provides an overview of the benefits of these technologies, an
architectural view of each, an analysis of the major offerings, user case studies,
and considerations and tips for selecting and implementing products. We hope you enjoy the book and that it makes your journey into implementing
these technologies a smoother ride.
About This Book
To help you find the information appropriate for the phase you are in, this
book is divided into four major parts, plus the appendices.
Part I: Technology Evolution —Covers a brief history of related computing
technologies, discussing a number of recurring themes. It then provides a
more detailed history and timeline for blades and virtualization and their evolution
since 2001 and discuses blades and virtualization as significant evolutionary
steps, outlining the benefits they offer.
Part II: A Closer Look — Examines the architectures and specific features of
blade server systems and their components, as well as the various types of virtualization
and architectures/features. It also discusses related issues such as
clustering, management, and pertinent standards.
Part III: Hardware, Facilities, and Software Considerations —Offers questions
to think about when implementing blade solutions and virtualization,
including blade hardware considerations, system software considerations
(focusing on virtualization), and data center facilities planning (power and
cooling).
Part IV: Solutions—Presents a matrix-based approach for applying decision
criteria in differentiating products. This section includes a blade server system
matrix and a server virtualization matrix, with available products assessed as of
2006. It also offers an analysis of available blade and virtualization solutions and
discusses user case studies, with production implementations of blades and virtualization
together. Finally, it offers a glimpse into the future of blade system
and virtualization technologies.
Appendix A: Vendor and Product Information —Information in this
appendix was provided directly by the blade and virtualization vendors to
give an overview of their relevant product offerings and market focus.
Appendix B: Specifications and Standards ¡ªRelevant management and
other standards and specifications are outlined along with online resources for
more-detailed information.
Glossary¡ªQuick-reference definitions of blade-server-system and virtualization
terminology.
