Storage networking fundamentals: Storage devices

This sample chapter, taken from Cisco Press' Storage Networking Fundamentals: An Introduction to Storage Devices, Subsystems, Applications, Management, and File Systems, explains the inner-workings of both disk drive and tape drive technologies, shows how they are used in a storage area network (SAN), and outlines each technology's benefits and shortcomings. While the chapter's explanation of hard drive and tape drive functionality won't be new information to the seasoned IT pro, people managing SANs should find the section on optimizing disk performance in storage networks particularly useful. http://techrepublic.com.com/5138-10592-5685174.html?tag=FL
