Networks Large network, school project

Hi everyone
This week we got project week thing in school, no lesson, just 1 huge project. This weeks project was to fix networking, servers, computers, printers, software and basicly everything you need for a full working network.

So, this is my little sketch, and i have some questions about it.

Blue guys are students, 1 blue guy = 22 students
Green guys are teachers
Brick wall = Firewall
Box with arrows = Switch
Circle with arrows = Router
Cloud = Internet (10mbit fiberoptic)
Antenna things = WLAN Access Points
Lightning thing = Wireless signal
Imac = Network technican
Flatscreen = Media room
Stationary PC = 30 PCs used to teach kids about hardware, networking and stuff like that
Computer Chassi = Servers
The thing between internet and firewall = Bridge

Now I've explained everything, so lets move on to the questions.

1. Will the teachers be able to contact the servers at the network technican?
2. Would you place the bridge, router and firewall in some other order?
3. Can anyone breifly explain how domains work? I want to have 1 Teacher domain where they have access to like everything and 1 student domain that cant contact the server located near the teachers or the teachers computers.
4. I need a fileserver, it will have about 2TB of harddrive space. It will store some programs, files and such needed for some education, and every student will get some space where they can upload stuff. How fast does it need to be? CPU, RAM, MOBO?
5. I need a Router cable of gigabit useing TP cable, atleast 4 ports, any ideas? Money is not a problem, got about £40000 left to spend.

I think that was all for now, more questions might come later.

 

Ok, I may be not a huge amount of help but here goes:

1) Yes there is no reason why this should not work, you have shown the links connected through the router, I am assuming that this is a switch built into the LAN side of the router so it will work.

2) I am not entirely certain why the bridge is there, what are you bridging to what?

3) I am no expert on domains, also you don't mention what OS you are running but if we assume that it is Windows then can you not be more effective with using group policies.

4) 2TB!!! What exactly are you going to be storing on there? Oh, I see that is what the 10Mbps pipe is for But seriously with that sort of size you sould start looking at something more than just a PC with some large disks stuffed in it. You would have to look at how much data is going to pass through it, only then can you guess at wether you need a clustered SAN or a P3 600 with 512mb ram.

5) Well I think that you should start looking at Cisco kit. If you 'only' have a 10Mbps internet connection then the router technically does not need to be faster than 10Mbps, in reality you would probably strugle to find one which is not 100Mbps. Once you have a good router you can then just stick a gigabit switch on the back and all is good.

Hope this helps

I would make all connections between servers and switchs Gigabit as they will be moving alot of data.

 

perhaps something like this would be more appropriate, you'll have to make changes as required to proply suit the layout of your school. Proper layout that takes into account where traffic volume is, can be key to keep things speedy. Note i completely seperated the student workstations and the student file server from the rest of the network, the only traffic that comes from their now is traffic to the domain controller. I've read a few books on networking and know the basics, but what i've supplied might not work, best to ask a proffesional



1. Yes, provided you set it up properly
2. I don't see the point of the bridge even existing
3. Domains work by authenticateing users and allowing acess to resources on the network as defined by the network admin.
4. Perhaps a p4 2.4c with 1.5 gigs of ram, and a 875p mobo for maximum RAID goodness
5. I don't think gigabit routers exist (i honestly don't know)


Question: is this real life or an assigment given to you by your teacher?

 

Man, someone went crazyass with Visio

 

Damm, why didn't I get to do a project like that when I was at school

By my very very rough calculations, that's about 1GB personal storage space per persion (we get about 50MB here at uni)

Lose that bridge thing. You want a proxy server to act as a gateway to the interweb.

 

How do you know that there are two thousand users? There are only 140 terminals shown...

Here at university we get just 20mb which is not very much at all, at school we got quite a large allowance but people just filled it up by installing games such as UT.

And yes a proxy server is really essential to save bandwidth and make the whole thing more responsive, especially if you you consider a class all looking at the same website..

why can't you put the teachers and students on the same server.

Surely they pretty much all the have the same rights its just the teachers have more space.

 

Becuase then the network couldnt be seperated as well. More traffic on a single server is not a good thing. Anyways he has alot of cash to get the job done, so why not..

 

Ok, I've talked to a network technichan and a cisco certified teacher about the network, and now it looks like this:


Where all the cables will be drawn, where I'm going to place the APs and stuff like that is shown on this picture - http://server5.uploadit.org/files/jakeeTheCake-orebro2.jpg
Green = teachers network
Blue = Students network
Red = the 2 rooms used for courses in LAN, Computer communication, PC Knowledge and such.

The teachers are on a seperate network cause they have stuff on their server and computers that the students should not have access to. Stuff like tests, grades, info and so. And like 99% of the kids in the school are geeks in some way, so someone always try to be a smartass, so placeing it further away on another network with another domain will make it harder for him.

The fileserver is not only for personal storage, it will hold stuff like photoshop, office, java and so.

Internet is now 40mb fiberoptic.

The entire network is gigabit (well, not the wlan, its 54mbps)

I think it's kinda done now, got to show it and present it first tomorrow morning, so if you see anything thats just plain wrong tell me.

If you got any general tips of what to think of while presenting it, please tell now

 

Might want to think about an apps server if you have the money to splash about

 

I still think that hooking everything into that main switch is still going to be a problem. If multiple people try to move large files, your network will grind to a halt. Also, are you sure that none of your cable runs are longer then 100m?
