Hi,

from what i learned by myself and from couple of tsm users in our area,
the aix implementation is even more stable and scalable comparing to nt.

TSM itself on nt is as stable as nt itself,
if you are happy with nt you will likely be happy with tsm/nt as well.
I am just setting-up new nt/tsm box, mainly because our know-how in unix
is small.

But if my requirements were harder I would swap to aix and buy aix
know-how along with the product.
For example, a neighbour company with x-terbytes of backup data and ATM
backbone could double
their tcp-ip throughput by swapping to aix,
inspite of their perfect NT know how and weeks of tuning and comparable
HW used for both NT and AIX.
But I do not need that, so I stay with NT.

regards
Juraj
