I've tried to go through two different reps and read a website talking about CAL's. I understand what a CAL is but not how to determine how many I need in our environment.
For example, I want to buy three copies of Server 2008 R2 DataCenter Edition with two proc licensing for use in our virtual environment. Inititally I'll have about 4 servers virtualized and 100 end users. Over the span of the next 3-12 months that will increase to roughly 40 VM's once conversion is finished.
Right now these virtual servers will be used for things like SQL, Mail Archiving, Accounting Software, File Server, etc. In the 3-12 months this will include domain controllers, exchange, print server, an all the other software departments use.
