Can anyone give the technical reason why auto detect on Server NICs cause such horrible performance for TSM server backups and restores. We have our TSM server NIC set to 100MB Full also our switch Port set to 100 Full but we have users with sorted networks such as 1 GB switches plugged into 100 M wall jacks and travel across several routers., well you get my meaning. These people or demanding to know why they take 8 days to restore 6 GB. They have their server NIC set to Auto detect, They have a 1 GB switch that the server and several others are plugged into because they want hi speed between these servers. But this switch plugs into a normal 100 meg wall jack to get to our data center. I have instructed them to put the NIC to 100 Full and possibly move off swith but they want a technical reason why. They are developers.
