A few customers of ours called us or sent us links over over the last few days to point out this article which features Zerowait. I like the article a lot! The article goes into the proper way to purchase used and remanufactured equipment and what to watch out for.
The article also has some bullet points that refer to studies that say that many customers are looking for a ROI on their storage gear in the 5 to 7 year range, but as I have pointed out previously, NetApp; like so many other manufacturers, focuses on a refresh cycle of 3 years. This is the disconnect that enables Zerowait to grow. Zerowait focuses on providing affordable ongoing service and support for systems beyond the 3 year window, which are still reliably serving data.
