Like in any job field, no one can predict the future. I am certified in NCSD for NetApp and I am going for my next cert, which is NCIE-SAN, also with NetApp. Where you should start is basically getting your certifications in Server+ and MCITP. Now, to be certified in NetApp, you will need to be a member of NetApp, so that may be difficult for you unless you are currently working with the company and their equipment.

Hope this helps you out to some degree, but like I said at the beginning, I don’t have a crystal ball and things change all the time. I remember when being a web page designer was the top job to have. Now, I don’t even believe it is in the top ten. Good luck in your career.
