Using SANs and NAS: Help for Storage Administrators

by W. Curtis Preston

Data is the lifeblood of modern business, and modern data centers have extremely demanding requirements for size, speed, and reliability. Storage Area Networks (SANs) and Network Attached Storage (NAS) allow organizations to manage and back up huge file systems quickly, thereby keeping their lifeblood flowing. W. Curtis Preston's insightful book takes you through the ins and outs of building and managing large data centers using SANs and NAS.

As a network administrator you're aware that multi-terabyte data stores are common and petabyte data stores are starting to appear. Given this much data, how do you ensure that it is available all the time, that access times and throughput are reasonable, and that the data can be backed up and restored in a timely manner? SANs and NAS provide solutions that help you work through these problems, with special attention to the difficulty of backing up huge data stores.

This book explains the similarities and differences of SANs and NAS to help you determine which, or both, of these complementing technologies are appropriate for your network. Using SANs, for instance, is a way to share multiple devices (tape drives and disk drives) for storage, while NAS is a means for centrally storing files so they can be shared. Preston exams each technology with a vendor neutral approach, starting with the building blocks of a SAN and how they can be assembled for effective storage solutions. He covers day-to-day management and backup and recovery for both SANs and NAS in detail.

Whether you're a seasoned storage administrator or a network administrator charged with taking on this role, you'll find all the information you need to make informed architecture and data management decisions. The book fans out to explore technologies such as RAID and other forms of monitoring that will help complement your data center. With an eye on the future, other technologies that might affect the architecture and management of the data center are explored. This is sure to be an essential volume in any network administrator's or storage administrator's library.

I bought this book a long time ago, and it was probably dated even when I bought it. However, I went into it wanting to learn differences between SANS and NAS, some history of Fibre Channel, and to some degree I wanted it to be from a more dated perspective. Whereas I got more out of the section on storage area networks, I felt the bit on filers was a bit more sparse. The most important thing is I learned some concepts I set out to learn.

Lots of good info. A typical high-quality O'Reilly book. Somewhat outdated at this point, but a useful start for someone who wants to learn about FibreChannel, NAS, SANs, and related technology.

Pretty dated book, however it still provides a good overview of SAN and NAS operations and configurations.
