Storage Area Network School: Table of contents

What is a storage area network? What are the benefits and pitfalls of installation? How can a SAN fit into your organization? These questions and more are answered in our Storage Area Network School.

SAN

Storage-area networks (SANs) have the ability to save a company money, hasten backups and help consolidate the data center. But a SAN is not to be left alone. It's a complex, growing, breathing entity that constantly needs to be tweaked and upgraded.

So what is SAN School? If this is the first time you are asking yourself, "What's a SAN?" then SAN School is for you. If you are implementing your first SAN and need implementation and migration help -- SAN School is for you. If you are far along in the SAN process and need to extend your SANs or connect SAN islands -- SAN School is for you. The authors of Storage Area Networks for Dummies, Christopher Poelker and Alex Nikitin, are your SAN School professors. In each of these lessons they'll walk you through what a SAN is, all the way through connecting those last nodes for optimal performance. School is in session, so enjoy!

Lesson 4: What makes a SAN stop
Because SANs need to be tailored to one's environment, choosing the right gear can make all the difference between a successful SAN implementation and a dud. Take preventive steps to make sure your SAN isn't doomed from the design phase. This lesson looks at avoiding poor SAN design, and choosing the right hardware and software for the job.

Lesson 9: SAN backup: The killer app
The killer app for implementing a SAN has been and will continue to be backup. In lesson nine, professor Christopher Poelker discusses the merits of backup over the SAN. Chris will discuss the options associated with SAN backup, including backups over a dedicated LAN, tiered backups, LAN-less backup, serverless backup and more. He'll also touch upon snapshots and give you exact formulas to calculate backup windows. This lesson also offers tips and tricks on how to find and rectify backup bottlenecks.

Lesson 13: Storage outsourcing
Trusting your mission-critical data to a third-party provider isn't a decision you can take lightly. In Lesson 13, Alex Nikitin takes a look at your primary SAN management options. One, to completely manage all  your data in-house. Two, to completely outsource all  your data. And, three, to use consultant or vendor partners to accomplish data management. Alex states the pros and cons of each method.

Lesson 14: Troubleshooting your SAN
"If anything can go wrong, it will." We all know this to be Murphy's Law, and when it comes to SANs it applies 100%. At some point, trouble will arise with your storage-area network. Alex Nikitin will help diagnose the problems you may want to look for first, such as checking for connectivity problems, and using system error logs and switch logging.
