I work in a organization where the network infruastructure is very old. Now managenment wants to deploy a new network with new cabling and all. At present network is centerlized meaning all the switches and hubs are installed in one location and cables are running to different departments. They want to distributed network meaning every department should have their own switch.Now they are saying that buy a swtich which is compatible with fiber optic. And they want to connect their database server with swtich thru fiber link. Since all the clients exists in different departments uses database(oracle). Now my only concern is that is it good idea to deploy whole network with normal cables RJ 45 cat6 and connection between switches and server will be of fiber optic.???
Suggestions is this regard will be highly appreciated.

Thanks

It will run just fine. I do not see any problems at all, just make sure the network design (all computers from one department are located near by or the switches have VLAN capacity, etc.) fits your requirements. Now they want to improve and have the money to invest, good design, good equipment should give a much better network. Good luck

UMMM ! Optic (45M-2.5G) verses copper (56K - 1.5 M) Makes no sense to me. All connected to the server ? Why ?

If you can not note my sarcasism, no hope !

It will work fine but to get the best results you'll need some very powerful servers as most servers couldn't hope to come close to using 1/4 of the available Optical bandwidth.

If you are using medium Blade Arrays of 500 CPU's it will work very nicely just don't look behind the blades too often. :D

Converging a department on a switch and routing the switch to central on fiber is smart.

Fiber gives you maximum bandwidth, higher resistance to interference, more avaibility to grow.

Go for it.

sayal hi! if you give number of servers & users, building dimensions etc. a structured cabling design can be drawn . Centralized cabinet is easier to administer and causes less faults. Fiber or copper doesn't matter best cost/performance product would be a gigabit - fast eth architecture . Server pool would have gigabit cards and ports on the main switch . Through the other gigabit ports branch down to your departmental switches . User ports would be autosense 10/100. If you have more than 100m use fiber backbone , thus fiber modules on the core and edge switch on either side of the link. Distribute as copper to users. If your server is within 30m of the switch , no need for fiber ....
