Per Server, Per Device/User

In an environment of 3 Windows Server(s) 2003 with 50 networked
workstations, which licensing model is more advantageous? Per Server or Per
Device/User? We don't plan to use web servers at all.

3 servers will be configured as follows:

Server1 - AD controller, file/print server
Server2 - AD controller, file/print server
Server3 - member of domain, Exch 2003

If I understand correctly, using per server mode means that we apply 50 CALs
to the server instead of the workstations/users. So in this case, we'll have
to purchase a total 150 CALs... 50 CALs for Server1, another 50 for Server2
and the last 50 CALs for Server3. Is that correct?

Any help will be appreciated. Thanks.

 

About the only reason you would use "per device" is when you have more users
than you have devices.

 

Unless you have more then 150 users you would never want to go with per
server. If there is just one person per workstation then you only need 50
per user cals. The cal goes with the user no matter what server they
connect with. Even if you had 10 more servers you wouldn't need to adjust
your CALS. Per server is good if you just have one server and not all your
users are on at the same time.

 

Thanks for your reply.
