Storage Area Network School: Table of contents


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?" -- 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 20-minute 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 -- enjoy!

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 of SearchStorage.com's "SAN School", 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 window. This lesson also offers tips and tricks on how to find and rectify backup bottlenecks.
