Our VAR says they went over this extensively with Tivoli (several iterations) 
and the result:

You only need to license the CPUs of the proxy server if you back it up; you 
MUST license all the cpu cores of the VMWare hosts that are backed up via the 
proxy server.

We just started to migrate to VMWare this year, and even with this requirement 
our overall core count has dropped.

That depends on who you talk to - some Tivoli reps will say that the
VMWare host cores need licenses as well.

The license for the TSM client in this case is based upon the VCB proxy
server running the TSM client.

FYI - the waters get even murkier when you start down the VCB path.

Try posing this scenario to your Tivoli rep: all VMWare guest backups
have been offloaded to VCB proxy servers, and the TSM client has been
uninstalled from the guests.  No TSM software exists on the VM hosts at
all.

Now ask them which physical cores need to be counted for Tivoli
licensing - the answer may surprise you.

Just to be clear -- that includes TDP licenses?  There was a question
today on the list ( http://tinyurl.com/47zjbe ) where at least one of
the answers seemed the opposite of what you're saying, and another said
"nobody knows."

I speak about VMware backups, and so I get asked this a lot.  I just
want to make sure my answer is dead on.

TIA
