I'm the admin for a company that has grown very rapidly in the last few years.
We orignally ran SBS 2003, which I successfully migrated over to SBS2008 a few years ago. In the past year we're gone from <20 user to over 50, with plans to grow even more yet.
I'm currently trying to work out the costs of various different options as part of our overall DR process. Due to the fact we're growing rapidly I'd like to begin the process of moving us off of SBS & run a separate DC/File sever & Exchange box on either Server 2008 / 2012.
I guess for simplicities sake these machines will likely be virtualized on to 1 new VM host machine.
I think I'm right in thinking that that will mean 1x Server & 1x Exchange server licenses (not sure how many processors etc to go for here) plus 50x server CAL & 50x Exchange CAL.
Where I begin to get confused is that one of the options I'm considering is having an offsite co-hosting location where I have another VM host running essentially the same set up. If I had exchange replication & backup DC with files copied using DFS etc, then from a DR point of view should something happen to site 1 then I have an immediately available site 2 up & running, then I'd only need to repoint incoming SMTP etc.
If I go down this route then do I need 100x Exchange CALs & 100x server CALs or not as I'm only 'using' 1 site at a time.
Thanks,
Dave
