Hey everybody. It has long been known that moving large amounts of data, such as many displays, over the nodebus will cause smurfing.... That being said, I have been working on a configuration like the following for several years. (use fixed font for align for viewing the bad ASCII drawings.) AW51F------WP7001 |-WP7002 ... | WP7007 The 70 series workstations do not have a secondary ethernet port. Displays were converted to .g files and moved to or from the F box as needed. Then the .fdf displays were copied by windows explorer from a "master" NT box to the rest of the NT workstations. This worked reasonably well as long as no one attempted to copy too much data at a time. How much was too much? I don't know, I know at least a directory at a time was doable, and possibly more. Now they added an AW70X running XP and an ATS with a CP270 so it looks more like AW70Xp -----ATS-----AW51F |-WP7001 ... |-WP7007 Now copying even one file of ~ .5 meg causes smurfing, and the problem seems to persist until the boxes involved in the copying are re-booted. I don't know if the ATS is jamming a lot of data onto the nodebus and amplifying the problem, or if we have something else that needs adjusting. Has anyone else seen this kind of behavior? Let me know your experiences in this area.
