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.

Great book; gets to the point
Without having to read through a bunch of, "this is a network, this is how traffic is passed, RAID, and its benefits", blah blah. Gets down to what is the benefit of a NAS, SAN, and what is up with all the hype. Great book, for under 200 pages. Thanks for not killing a tree with extra fluff.
