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!
