VTL has been looked, but never decided upon. And believe it or not, we have moved storage agents to 10 G networks. The rest of theses storage agents are huge servers that are backing up at least 800 GB (and in some instances 5 to 10 TBs). We have some storage agents that do full backups on the weekends and can easily back up between 20 and 30 TBs.

This will reduce the number of paths to maintain and the complexity of the zone db. I guess your situation is the one situation that you want to look into a vtl or other tape virtualisation solution, so you don't have to buy a tape drive for each server, client and whatever. Question is, do you really need all those lanfree clients, or is it cheaper and to invest in a bit of 10 GE network kit and use the LAN and have TSM do what it's good at: storage hierarchies. > Thanks, > Sean -- Met vriendelijke groeten, Remco Post [EMAIL PROTECTED] +31 6 248 21 622
