NO Tsm will write to a tape untill it is full and continue on next available tape - so that one file can be spread over several tapes. you are welcome juraj -----Ursprüngliche Nachricht----- Von: Ung Yi [mailto:[EMAIL PROTECTED] Gesendet: Freitag, 08.

Thanks, yi >>> [EMAIL PROTECTED] 08/07/03 03:19PM >>> Look out for the network speed on this! 100 Mb is 15 GB/hr. 1 GB is 50 GB/hr. So, if you get 4 sessions going (4 nics on TSM) you could crank 200 GB/hr on the 1 Gb network. Your milage will vary!
