Redundant Array of Independent Disks (RAID) technology is becoming a standard feature of computer systems that support missioncritical services like file sharing, mail exchange, or Web servers. RAID offers two benefits to these essential systems: improved I/O performance and failsafe data storage.Although bandwidth problems on networks are well documented, the internal data transfer bottleneck that exists at the hardware level in each system can also leave you with perplexing performance issues. RAID is a costeffective and easytomanage way to alleviate this bandwidth problem by distributing the I/O load seamlessly across multiple disks and controllers.RAID also provides uninterrupted data access through disk mirroring and parity algorithms. That means systems can remain online even during a disk or controller failure. RAID is scalable, making it robust enough for large, hightraffic sites and small, critical systems. By using RAID, system administrators can combine single disks into terabytes worth of data storage.Managing RAID on Linux covers everything system administrators need to know to put together a system that can support RAID. You will learn about the different types of RAID, along with associated technologies and issues, and how to choose the best RAID system for your needs. With a stepbystep, handson approach, the author guides you through the installation of either Linux software RAID or a hardware RAID card. The book shows how to build an array and optionally install a highperformance file system. Contents include:An introduction to RAID and LinuxPlanning and architecture of your RAID systemBuilding a software RAIDSoftware RAID tools and referencesBuilding a hardware RAIDPerformance and tuning of your RAID system RAID has become the lowcost solution of choice to deal with the everincreasing demand for data storage space. Written for system administrators, power users, tech managers, and anyone who wants to learn about RAID technology, Managing RAID on Linux sidesteps the oftenconfusing vendorspecific approach you`ll find elsewhere to give you the straight story on RAID. Even nonLinux users will find this book full of valuable material.
