"SAN Building Blocks"

Join Christopher Poelker, co-author, Storage Area Networks for Dummies, for a lesson on SAN basics. This lesson defines SAN components and their uses, as well as an in-depth look at storage arrays and RAID.

More about "Lesson 2: SAN Building Blocks"

On a SAN, as the data goes through the network, it passes from the host layer through the fabric layer and then it gets stored on the back end. What are all of these layers? In chapter 2, you'll learn about the different layers of a SAN, how they're all connected and what components make up each layer. When building your SAN, you'll need to know which components fit with which technologies as well as how the SAN comes together with host bus adapters (HBAs), switches and cables.

In this chapter, you'll learn about these issues plus get some advice on how to make your SAN scalable so you can get the greatest cost benefits for both the short and long term. Finally, this chapter explains the difference between modular and monolithic storage arrays, and the different types of RAID and the benefits of each. When you've completed this chapter, you'll be able to outfit your storage environment with exactly the right components and technologies to fit your needs for now and later.

What you'll walk away with:
** Knowing what makes up a SAN
** Determining which components are right for you
** Knowledge of SAN ports and naming

** Understanding storage arrays and storage array design
