I am a Middleware programmer.I have a reasonable understanding of NW concepts.But I do not have practical experience of setting up one.As a part of my curricular, I have aproject which necessitates to do me that.Can anybody help me as to how I should begin ?Are there any web sites with free tutorials on this ? Please help it is very urgent.
Basically to start with I have 35 hosts in a floor building of which one host is a Database server and the other is a mail server.All the incoming and outgoing mails of the office floor employees are handled by the Mail Server and day to day office transcations are managed by the Database server.First how should they form a network ? Second what are the necessary hardware products required and their specification and their cost ?
If you only have 35 hosts on the network, a single 48 port switch should do. I don't know if there is Internet connectivity to consider and things like that, but if you just want 35 hosts on one network to be able to communicate with each other and to a DB and mail server...just get a 48 port Cisco Catalyst (like the 3550 or the 2950) and assign all the hosts to be on the same IP subnet. Something like 192.168.1.x 255.255.255.0
A 48 port 2950 switch is about $4500
A 48 port 3550 switch is about $5000
There are cheaper switches out there (3com, HP, etc.)
Thanks a lot for your valuable reply.What if I can connect 20 hosts each to 24 port hub.One hub connected to DB Server and the other hub connected to E-mail Server.The two hubs can be be mutually connected.
Now the next step is that we have a 10 such clusters of 35 hosts in separate buildings which have to be connected . So I plan to connect them with a bridge using FDDI.Pls suggest.
It all depends on how much you have in your budget, what you've suggested isn't that bad of a plan-you'll have 10 isolated collision domains; however, with 350 hosts on the same flat broadcast domain, you could run into performance issues. That's a lot of hosts on one flat segment especially with no layer-2 switches isolating the collisions domains per port in each cluster. Also, I'm not sure if each cluster will have an email server and an db server or is there just one email server and one db server?
I would look to see what Layer3 functions your FDDI bridge offers (if any)...
