Using SANs and NAS ReviewIf you are looking for an overview of SAN and NAS that is both technically informative and equitable, this is the book for you. I bought it to better understand NAS-SAN convergence trends and it was invaluable for that purpose.
As with most O'Reilly books, it doesn't underestimate the reader, yet still manages to cover all the bases from basic to bread-and-butter, and beyond. The prose style is casual but very precise and always clear.
I want to stress what an earlier reviewer pointed out: it is especially strong on real world backup and restore issues...which is MUCH more important and complex than is initially apparent.
If you are tasked with building a real-world storage infrastructure: read this book first. BTW, because my local B&N was out-of-stock, I paid extra to have [Amazon.com] expedite this slim volume, (grumbling all the way), and ended up happy as a clam about it. Best IT book investment I ever made.Using SANs and NAS Overview
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.
