Thanks to everyone who contributed to this today.

I'll pop off and do the maths now :-)

Farren,
This discussion comes up a few times a year from new and old alike.

Here is the link to the PVU table from IBM. It changes regularly.
http://www-01.ibm.com/software/lotus/passportadvantage/pvu_licensing_for_customers.html

Sub-capacity licensing is available for VMs. 
However, if all your VMs need to be backed up, you are probably better off 
licensing all the procs on the ESX server.
It most cases it is cheaper than licensing each guests processor entitlement. 
If you only have a few VMs that require backups sub-capacity may be cheaper.

TSM license costs are based on PVU per core multiplied by number of cores per 
client/server.

Also take into account whether you are using TSM standard or enterprise edition.
A comparison is here.

Subject: Age-old licensing question

Hi all

I know I started this in a reply to my backing up of virtual machines bit 
thought it best to start a new thread.

My simple question is... how do I find out how much licensing costs? :-)

I know it's not that simple though.

My basic questions are this...

1) do I need to use the PVU calculations to work out how much a standard BA 
client license will cost or can I just pay for a standard client license?
2) do I use the PVU calculations to back up virtual machines?
3) are standard BA client licenses cpu based (or PVU)?

Thanks in advance

Farren
