Hi..........

What is the criteria that tells a person that a 2nd TSM instance is
needed??  ...

The historic List consensus is that such is needed when, despite
realistic tuning and schdule adjustments and waste pruning, the TSM
server is becoming unable to meet daily demands within a 24 hour period.

There may remain, however, opportunities to improve throughput by
means of infrastructure improvements, such as adding processors to a
multi-processor box, going to next-technology tape drives, adding
higher-RPM disks, etc.  Most sites strive to avoid adding to the
workload of costly administrators, and so endeavor to improve on
hardware - which is often due by the time it is perceived that the
current server is straining to meet demands.
