TSM on the AS/400 is like TSM on a mainframe... it depends on how you set it
up, how much resources are alocated to it... what your network speed and
load is... what model of AS/400 you have...

We have a model 640 with 1.5 gigs of memory allocated to TSM with a Dsik
pool of over 40 gigs... and we use the IFS to store the Disk pools and
Database...

From our Fileserver clients (NT), we get about 4 to 6 gigs an hour... from
Exchange we get over 12 Gigs an hour...

Sometimes we have the same performance as you mention, but that's when 10
clients are backing up at the same time...

We compared our AS/400 TSM setup with our German division who uses the NSM
box (Unix) and our performance rates were better... We also compared with
another comapny who uses ADSM on OS/390... same results...

Like any platform, you need to fine tune... and monitor...
