Dale,

Yes the NSM's are the only IBM Boxes that we have but we have now started to
move forward
on Sun TSM Servers connected to 3494 Libraries. At the moment we have 5
NSM's and 4 TSM Sun Servers.
Admittedly the Sun Servers are a higher spec but the performance is
exceptional compared to the NSM.

Obviously there are some advantages to using JFS, but I would say that its
effect on performance rules it out as an option for
us going forward.
Also the NSM's limited scalability, its inflexibility and its confusing and
frustrating support arrangements means we will can them as soon as we can.
