There are plenty of solutions out there. Are you looking for a specific brand? EMC & NetApp are frequently requested. I work for Berkeley Communications http://www.berkcom.com/NetApp/
which is a platinum authorized NetApp (Network Appliance) reseller</a>. However, we also have many other solutions, including custom jobs. We've got a bunch of SAN, NAS, filers, hard drives & disk drives, etc., check out our website. The homepage is http://www.berkcom.com
which is slightly different than the above link for NetApp specifically. In case you aren't too familiar, NetApp and EMC are competing heavily for the computer storage & backup market. They are considered the leaders in this specific industry.
