Help!!! network setup

By nitobd ·
Hi all,

It is my first time to setup a network and I am little confuse how my cable guy has setup the connection...

It's a good network to have the following setup?
One room that have the router, server connected to a small switch (8 ports), and then have a one ethernet cable connected from the small switch to the main switch (48 ports) where all the clients will be connected.
I can't have the main switch on the same room with router and server because of the all the cables of clients are being drop on the room where the main switch is, and the internet modem drop is on the same room where other equipments are, and I can move them where the main switch is because of the room condition (boiling and heater room)

1. Is this a good setup? It won't affect the traffic of users accessing the server and the internet coming from the router since all connection is coming from one cable?

Your answer will greatly appreciated.

Have you fired it up, yet?

Or, are you frightened out of your wits to do so?

Greatly appreciated will be your answer.

I haven't connected everything yet

But I am looking at all possible setup before I do, but the cabling is already done.
That is why I want to make sure my foundation are good before I start putting everything toguether.

Some thoughts for what they're worth

by Churdoo In reply to Help!!! network setup

I don't know that I would categorize as good or bad because sometimes we have to work with what we have, be it budget constraints or physical constraints or other.

I understand that you say it's your first network and your thoughts and concerns appear to be in the right place.

One would assume that the "main" switch is the best switch so having that in the "boiling" room is not advisable.

As you've pointed out, with your server traffic and internet traffic "sharing" the single run from the aux switch to the main switch, they are sharing the bandwidth of that single run. With most internet bandwidth still 10mb, 6mb, or less, if the connection to your main switch is 100mb, that's still less than 10% for internet leaving the rest for server traffic.

Having said this however, I myself would still want this traffic separated as the server connection is likely to be the busiest and therefore the LAST that I would want to share. I want my servers part of the main distribution system. If you can pull a second run from the main switch to the aux switch location that would do 2 things, actually 3 things:
1) allow you to dedicate an entire run to the server traffic without sharing
2) allow you to connect the server to the main switch (I always like my servers plugged into the main distro, boiling room notwithstanding)
3) you can even run the internet traffic directly to the main switch eliminating the aux switch.

"My cable guy" knows NEVER to pull a single run in any portion of any job he does for me. If you're going to pull a run for anything, pull 2, or even 3 or 4 depending on the intended use at the location. It is minimal additional labor to put a second spool and pull simultaneously, and only marginal material cost.

Hope this is helpful.

Very good point

Yes that what my guts is telling me. To have each equipment (server, and router) connected individually to the main switch, but he is so stubburn that it would work fine.

Thanks for this great comments

Well as stated above I don't like Switches in places

Where they can be subject to possible water penetration either or other Humid Environments. But having said that we have to live with what we have and make do with what is available.

The only thing I can think of here is that you have the Router and Server connection to the 8 Port Switch in the Server room and then going to the main switch. Depending on what the server is supposed to be doing I would probably prefer to have the Router feed the Server and then the Server feed the Main Switch removing the 8 Port Switch from the chain and a possible point of failure.

But then I would also be using ISA on the Server and using that to limit any Internet Traffic into the Network assuming that the server is running some form of Windows Server. If it was running a Nix Distro I would still have it as the Gateway filtering all of the Network Traffic and also pushing out any Workstation Updates through Windows Update Services.

But here it depends on what the server is supposed to be doing as to what gets put on it and what it's used for.

However I do prefer to have a Gateway Device that I can set Rules on between the Workstations and Internet. But maybe that's just me.

As to your question there is no Good or Bad just what works and what doesn't work, provided that you are not attempting to share 48 Workstations for High Usage Internet Traffic there should be no problems here and even if all of the workstations where being used to Stream Video to/from the Internet provided that you have a fast enough Connection there shouldn't be a major problem.

I also have more than 1 cable pulled per run as the cost of CAT cable is cheap and having the redundancy in place if a cable fails or otherwise gets damaged is always a good fall back position to have. It can take a very long time to find a break in a CAT Cable run and depending on what happens in the building it can be very expensive to run another cable to replace a failed one.

Not to mention the time involved replacing any failed cable run.

Only thing I can think of here is if you are planning on using Exchange or similar you may want to look at 2 NIC's on the server and using it to Chanel all traffic through. It would be rather pointless not doing this if that was what you where intending.

Wow that a lot of info to caught

Thanks for you answer, but I got little interest the way you've said you'll setup the router to feed the server and then the switch. On my setup, I am planning to have the Internet modem connect to the router, then to the main switch (of course from smallthe 8 port switch), and have the server connected as well on main Switch, so I can assign it an IP and everyone on the network could access the share folders and printers.
Please correct me if I am wrong. Having Intenet Modem->router->Server->main switch is the best setup? I though Modem->router and Server->main switch was the best option.

Also for the exchange, I will be using SBS 2008 that already have exchange with it, so no need to install as separate.

Well the way that I would do it is

To have the Modem, Router, Server, then Switch

So that all Internet traffic is coming through the Server and then being distributed across the network from the server. That way you can use the Server as a Filter to prevent Web Sites and other things that are not wanted and also have the incoming E Mail being distributed from the server directly.

To me it just makes more sense that way but I'm sure that others will see things differently and prefer different ways to set things up. With me it's just that if you are using SBS it comes with ISA included so why not make the most of it and use ISA as the Filter for the Internet.

If you do not have the server filtering all the Internet Traffic don't bother setting up ISA as it will not be doing anything useful.
