I know there's already threads about noobie's wanting to learn about NAS/SAN... I just wanted to start my own.
Currently reading through:
Storage Networks Explained 2nd Edition
I'll follow that up with:
Information Storage and Management
After that, are there any certifications and of you would recommend I get? I'm really not sure what I'm trying to get out of this besides more understanding and perhaps a job change. (here's my thread about what's currently on my plate:

I have applied in the past for a NAS/SAN type position without any prior theory or handson and I did not get the job. It looks like a pretty in depth topic and in my books would be very technical as well as specialized - so hands down, it interests me.
Can you name a few of the major types of corporations that utilize NAS/SANs that have full time technicians?
