With having 2008 Server R2 Enterprise installed on a machine, the recommended specs is 2Ghz and 2GB of ram. I want to setup network user accounts on this machine. I meet the OS requirements on the rack server I have with a dual core 1.8Ghz and 2GB of RAM, over 10 TB of drive space setup in RAID 6, and a 20/5 connection. Will this be an ideal enough system for 25 network user accounts to link up to this one server, or should I increase the ram if 2GB isn't sufficient. Strictly file storage, ftp, and user account usage only. I know R2 Enterprise supports 2TB but in a realistic world I'm trying to keep cost down, if 2GB wont be enough, what will?
