I'm looking to deploy multiple BES servers in a single org as the user count is quite high.

What I want to know is related to licensing, I'm assuming I need multiple CAL/SRP for the servers.

When installing the servers are they independent of each other or do they work as a group (e.g. like Exchange hub transport servers)?

If they are independent any suggestions on how to allocate users to servers

Thanks

Multiple BES installation in a single organization is quite flexible. You should probably post, or ask a moderator to move this post to, the BES admin forum.
