network redesign - VLAN/Subnetting
I'm in the process of building out a new facility and would like some input on the redesign of our network. Currently we have 2 buildings with a very flat network design:
Building A: 192.168.1.0 /24
Building B: 192.168.2.0 /24
The buildings are connected via point-to-point T1 routing traffic via older Cisco 1700 on Gateways 192.168.1.254 and 192.168.2.254.
Our new layout is a bit more complex and I would appreciate some assistance.
Building A:
- Primary Network on 192.168.1.x
- IP Phone on 192.168.2.x
Building B:
- Primary Network on 192.168.10.x
- Call Center Network on 192.168.11.x
- IP Phone on 192.168.12.x
- Misc equipment DMZ on 192.168.13.x
- IP CCTV on 192.168.14.x
Both buildings are now connected via point-to-point DS3, plus Internet, and was planning on having our firewall act as the primary gateway between the buildings and the subnets. There is not a ton of traffic between the two buildings, but there are users at each building that need access to other's networks.
I have never really played with VLAN's before and I'm not sure of the benefit of VLAN over subnetting--at least in this scenario. I would like to keep our network as flat and simple as possible, if there is such a thing anymore.

In answer to the questions about our network, and size... We are not very large in that we have around 30-40 employees in each building plus all the related gadgets like printers and such. Probably totalling less than 90-100 devices in each building -- plus the new IP phone system which will add around 50 devices per building on their own network.
Each building has their own servers for file serving/print serving as well as applications. However we have one Exchange server for the enitre organization at Building A. Finally one of our goals is to provide remote site data storage and disaster recovery at each facility.
Our dedicated pipe is actually an OC3 SONET Ring that is broken into 2 DS3 for network plus multiple DS1 for PRI, T1, Internet, etc. By having our Firewall act as a router we bridge the two buildings via the DS3's and then have failover via Internet T1 (one at each location) via VPN.
