I've got a site with 1 SBS 2011 server, six users.
The complication is that the SBS 2011 server houses data for 3 different companies.
Let's call them Company A, Company B, Company C
Company A is owned by Mr.X, and Mr.Y owns Companies B and C.
At the moment, all users log into the SBS 2011 domain (CompanyA.LOCAL). They can access whatever company data they are privy to via drive mappings and permissions.
We use the Exchange facility on the SBS 2011 box, all mail for all the companies comes into the Exchange store and distributed to the users as specified.
All works well, however Mr. Y is now not wanting Company B and Company C data to be stored on the same box as Company A. He would prefer to have a situation where all Company B and Company C data is to be on a separate box, the thought being that if Company B and C went somewhere else, the box could be picked up and moved with all the data on it.
An added complication is that none of the companies want to use the cloud for storage (either email or data files).
So my first thoughts were to buy a decent NAS or even a PC and put the Company B & C data on this. But if they're looking for the email to be separate as well, that's another issue. If I was to get a PC, is there a third party mail server I could run on it that would not interfere with Exchange on the main server?
Any thoughts appreciated.
