Future of mainframe TSM

[Thomas Denier]

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.
