Preface
Linux has come a long way in the last decade. No longer relegated to the world of hobbyists and developers, Linux is ubiquitous and is quickly taking hold of enterprise and high-performance computing. Established corporations such as IBM, Hewlett-Packard, and Sun Microsystems have embraced Linux. Linux is now used to produce blockbuster motion pictures, create real-time models of worldwide weather patterns, and aid in scientific and medical research. Linux is even used on the International Space Station.
Linux has accomplished this because of a vast, and seemingly tireless, network of developers, documenters, and evangelists who share the common mantra that software should be reliable, efficient, and secure as well as free. The hard work of these individuals has propelled Linux into the mainstream. Their focus on technologies that allow Linux to compete with traditional operating systems certainly accounts for a large part of the success of Linux.
This book focuses on using one of those technologies: RAID, also known as a Redundant Array of Inexpensive Disks. As you will find out, RAID allows individuals and organizations to get more out of their hardware by increasing the performance and reliability of their data. RAID is but one component of what makes Linux a competitive platform.
