I am designing a new network for the small company I work for. We have 34 computers/servers with different network requirement (below), and I am not sure how best to approach implementing switches into the network.
I basically have 4 groups; Servers, Production PCs, Management PCs, and Internet PCs. The attached jpg displays this.
I require the following configuration;
- Production PCs can communicate with Servers but are shielded from the inernet, no access in or out (but I may want to change this in the future)
- Management PCs can talk to everything (servers, PCs and internet)
- Internet PCs can only connect to the internet, nothing else.
- Servers (2 Domain Controllers and 2 file servers) can connect to the internet for downloading hot fixes etc, but nothing else).
I am looking at getting a Cisco 1803 router for the internet connection as we are interested in opening another office and I would like to setup an tunnel between the two offices. This wont be immediately but I want a solution that allows it to happen.
Where I am stuck is knowing what switching to put between the router and the devices on the network; do I go for managed?, unmanaged?
Also how many switches? I could get one big 48 port switch but if it breaks; I'm stuffed. So should I get a number of switches? Would performance be affected?
Thanks for your advice
