We are a design company who have grown quickly.
We currently are housing our design data within one Dell server in a raid array, with HDD backups taken weekly onto external HDD drives.
I'm looking to separate the operational functions of the company from the pure file serving functions.
All of our designers use Mac Pros and don't need to access the Windows side often, the opposite is true for the operational side running Quickbooks and Office programs.
We will use Windows SBS 2008 in a VM for the Domain Controller and Quickbooks server and Exchange services.
We have a mac mini server I can use to serve the files if it can handle the load of just file serving. I could attach a disk shelf or raid array to it.
Or I could build a whitebox *nix solution to hold the design images, but I would like it to talk to the Domain Controller to authenticate users.
Backing up 4TB is currently done to external drives put into a fireproof safe. Our only connection at our current location is a T1, so backing up to a remote location is not feasible.
The new system should take into account a good backup solution.
I hope I've been clear enough to get some good advice, Thank you.
