My standard questions. Why do you need shared storage? What problem is it solving that you're having or anticipating having? For us, the drive was virtualizing our server environment and the ability to quickly standup a vm on any of our hosts should one become inoperative. That was the major push. Other thing is you would do well to download OpenFiler throw it on a box with a couple TB of disk space and play around. Use it for storage that is nice to have but not a deal breaker if it is offline. Get your feet wet and using shared storage opens up the world of possibilities, unlike reading about it.
