I'm about to install a Zen 6.5/Patchlink system. I read the documentation,but it really doesn't give scaled hardware recommendations. I'm going to purchase one server for Netware for the Zen components and one for Windows for Patchlink. I have 600 workstations spread across a WAN. Will PV, 1 GB RAM servers handle this? Or should I get more/less I plan to use all components but imaging.
