I am in the mist of designing a small private highschool network and I need a little advice from anyone. The school’s structure consist of three buildings, each building containing 13 rooms; 4 administrative offices, 7 classrooms and 1 computer lab.Each building is identicle in design and the library connects the three buildings serving as the central location of the campus. Each of the rooms mentioned will have one workstation with the exception of the computer lab which will have 8 workstations located in it.
A centralized server farm located in a room in the library will serve as the place of network managing the three identical building setups.
Ok here comes the shakiness. I’m thinking of having 3 level 2 switches in each building to connect the workstations together in each building. The administration PCs to one L2 switch, the classroom PCs to one L2 switch and the computer lab PCs to the other L2 switch. Remember each building being identicle in setup.
Now those 3 L2 switches in each building will connect to 1 L3 switch in each building, thus connecting each building together. Finally, the 3 L3 switches (one in each building) will connect to one main router that will be the point of internet access, the firewall and as well the connection point to the server farm.
So, that is a total of 9 L2 switches, 3 L3 switches and 1 router. The server farm will consist of 4 servers: a DNS/e-mail server, a application server, a web server, and a administration server. The horizontal cabling construction will be UTP cat5 and the backbone cabling will also be UTP cat5. The campus is deploying 10/100 BaseT Ethernet. Not worried about funding.
My question is what do you think of this design and what types of servers and network devices (routers and switches) should be used? Iwould appreciate any help or information from anybody. Thank you!
