help in project the best network architectur for the existing hardware

[tiago.teixeira]

Hello everyone,

In my work i've:
-2 switches HP2524
-1 switch DELL6224(L3,QoS)
-1 switch DELL3448P(L3,PoE)
-1 switch DELL2724 (managed)
-1 old switche allied tellesyn 24

and now all of them are uplinked like:
WAN->sw_HP2524->sw_DELL6224->sw_DELL3448P->sw_DELL2724->sw_alliedtellesyn

this is the topology of right now, but the network starts growing and i've must restruct the network to have more performance.Right now we've 100computers,6servers, a voip networkn supporting 70 internal extensions inside and a single 192.168.10.0 network which is becoming smaller each day.

All the switches are default configured, when we bought it, we plugged them into the network and thats all.

Now i want to make the network bigger and more scalable.
My intention is put the voip network in other network, isolate printers in other network, create a network for tests and the rest is for the all computers. I wanna split the current 192.168.10.0 network in for example, 192.168.11.0, 192.168.12.0, etc networks but i wanna be able to communicated between all them, for that i think the L3 switch makes that.

Well, i just don't have to much experience in this, about projecting the best possible network structure to apply here reducing broadcasts, arp requests, latency,etc and increasing performance.

Any ideas/suggestions will be very much appreciated.

Best regards,
Tiago Teixeira
