TSM as you know works well on the mainframe.  VM was the original WDSF
platform.  But with the I/O and processing power of UNIX systems
surpassing mainframes, moving off the mainframe TSM off the mainframe
isn't a bad idea especially since you are expanding your service.

Subject: Future of mainframe TSM


We run a 4.2.3.2 TSM server under OS/390. We have about 110 active
client systems, sending about 300,000 files and about 70 gigabytes to
the server each night. Our best estimate is that this workload will
double in the next two years. Is it reasonable to stay with an OS/390 or
zOS server in the face of the projected growth? If so, how do we prove
that the mainframe is up to the task? Most IT managers around here want
to believe that the mainframe is the wrong choice for TSM or anything
else.
