Hi Hans Christian,
Earlier this year we were considering going from PVU to capacity licensing but 
as 2/3 of our 1 PB primary pool capacity at that time was 'owned' by two nodes 
only, we asked IBM if we somehow could do both licensing schemes.

The answer was we would need two Passport Advantage sites and that the two 
servers + TSM server servicing those had to be in a completely separate 
location, and just moving the servers to our fail-over facility a few hundred 
meters away from the main facility would not be considered 'separate' enough.

Regards,

 - Bent

Subject: [ADSM-L] Mix PVU and Terabyte licensing

We are on a volume licensing scheme but we are considering PVU licensing for a 
new project since the volume/CPU ratio there is very high. As I understand we 
can do this as long as the two different environments are separate.

I haven't yet got a definitive answer on what IBM means by separate 
environments. It sounds reasonable that the PVU clients must reside on 
dedicated TSM servers but then I also hear some mumbling about separate 
libraries as well which would be a drag since we use library sharing.

Any comments or experience? We would prefer to be on the safe side here for 
obvious reasons.

Regards,

Hans Chr.
