By now I’m sure you have seen the "Deals of the week" page on the Zerowait web site. Maybe you don’t need a Network Appliance F840C NFS Cluster. Maybe since NetApp put an end to support on your equipment ,all you need is hardware support on your system. Could you need a card or a power supply or even a couple of drives? What ever you need, call Zerowait. It may not be the deal of the week, but you’ll find it is quite a deal.
I learned, more than a few years ago, that Zerowait is a good friend to have.
