Starting from scratch, I plan to have 600 users with e-mail, file and print, and Internet services. I will also have 10 servers used as LAN, proxy, and database servers. Two departments will need sufficient bandwidth and access applications from an Oracle server. We are also going to expand to four branch offices located in different states, one with only 5 users needing just a single internet. What hardware components do I need to build the LAN and WAN for all areas?
Software/Hardware used: Not sure yet, needing advice
