During the snow storm I had to use my 1948 Willy’s to go down my driveway. My Willy’s worked perfectly and it reminded me that appropriate technology never goes out of style. The same is true for your legacy NetApp filers. NetApp and Willy’s don’t make replacement parts for their older models, but replacement parts are available from specialty vendors. Zerowait specializes in providing parts, service and support for NetApp’s legacy filers. If you are satisfied with your older equipment and it satisfies your needs, why upgrade?
