Need a model name for a 100BaseT4 hub..

I'm network illiterate so...
Is there a 24 port hub that supports 100BaseT4? Or any stackable 100baseT4 hub that can support ~64 computers... It?s for a project just to calculate the cost on paper, so we won?t be actually building a room with 60 computers (all I need is a model name and cost +description so a link would be great). So far I couldn?t find a baseT4 hub (don?t ask me why they chose T4).

Also, I don?t know much about file and application servers, but for the same project I need to include 2 file and 2 application servers. Can anyone think of a model name + price I can put down on paper (a link would be helpful). I've been looking around some sites and all the technical terms are giving me a headache. 😉

<-- Don?t know much about servers.

Thanks in advanced, 🙂
 
100BaseT4 is an Ethernet technology where 4 pairs are used on a Cat 3, 4 or 5 cable. For common use (what we are used to seeing) is the 100BaseTX which uses 2 pairs (4 wires) on a Cat 5 cable. As you can see, the only reason T4 would be use is if you already have old Cat 3 or 4 cables installed and upgrading them to Cat 5 is too costly compared to buying switches that support 100BaseT4 signaling.

Ok. Thanks for the info.
 
Well, let me put it this way, (my sis is supposed to do this but I owe her a favour), I?m supposed to figure out the cost of the hubs and the 2 servers (and 2 backup servers). There are 3 buildings. 11 levels total. One level needs 60 computers and 4 printers. My job is only to figure out how many hubs (and the servers) is needed and find the cost. The brainiac who made up the plan (it?s a group effort). Went with 100BaseT4 hubs on 2 building (that?s 7 levels) and 100BaseTX hubs on another building (4 levels).

Finding the cost of TX hubs were easy cause there are so many, but I couldn?t find any T4 hubs (that is not discontinued).

Also I don't know crud about servers, and they have to support 60*11 = 660 computers. Basically 1 file server and 1 application server (and a backup for each = 4 total servers). The price I guess has to include any essential software.
 
How do you know what software is essential? Just the OSes? What apps does this mock company run?

Don't people do their own work anymore? I'm sure your sister will learn a whole lot about planning a network from this project. Have her give me a call when she graduates. I'd love to hire her.

Did they take into consideration what the maximum diameter of the network is? Meaning what's the maximum distance between the far left computer to the far right computer on the network. The maximum distance supported is 200 meters (end to end) before you have to put in a repeater to strengthen the signal (a hub or switch won't do it).

Do they already have the cables running inbetween the levels and building?? Is that the reason they went with 100BaseT4?
 
SSP, T4 is pretty seriously dead, and you might not actually be able to buy any T4 switches anymore. If you have cat5 cables, just use TX switches. If you have <cat5 cables, install new cabling. Really seriously, even if you do find a T4 switch, you may well find that it's cheaper to re-do the cabling and buy a TX switch than it is to do the T4 switch. Certainly that's a much smarter long-term solution because cat5e gets you to 1000BaseT and maybe even beyond, while cat3/cat4 is now seriously end of lifed as a LAN cabling technology.

That?s the thing. I had no idea why they chose to stick with T4. Also, about the cabling, that?s not really our problem since it?s a group work, but I told her to call them up and have that changed cause its obviously affecting our part.

But I guess right now my main problem is the servers. I have very little knowledge about purchasing any servers, much less know what an application server is. 😉
