More about "Lesson 1: The Storage Area Network:"

If you're experiencing a rapid growth in data and you'd like to manage it all in the same place, then you're probably a good candidate for a SAN. Other good reasons for choosing to implement a SAN in your storage environment include more simple management of your data, including the flexibility to manage your storage environment from anywhere at any time. Implementing a SAN lets you backup your data easier since it's all on the same server. What's more, with a SAN you can store your data in a place separate from your server, which could help protect your data in the event of a disaster at your main site. All of these factors combined can help you greatly improve the ROI on your data center.
