I try to keep my network as clean and simple as possible. I currently use no VLANs in my network except on VMware vSwitches for isolated testing. I plan to add VLAN’s later on but I just haven’t got around to that yet.
I use a Sophos UTM virtual appliance for my firewall and router. The firewall VM can run from any of my VM hosts so that I can have no interruption to the Internet when I’m constantly playing around or rebooting things. This means I need a connection from the modem to each of the VM hosts. There is a HA/clustering functionality you can setup with the Sophos UTM but instead I just simply use vSphere HA / vMotion. This saves me resources because I only need 1 firewall VM running.
Each VM host has 2 x MGMT and 2 x VM traffic up-links. In the real world these connections would be split over two stacked switches for proper redundancy but I only have one switch so just try to imagine. This allows me to have link redundancy on both the management and VM traffic link adapters.
Network: CSW1 (Core Switch 1)
The core / aggregate layer of my network stands on a very reliable Netgear GS748Tv3 48-Port 1GbE Switch. Almost all network and storage traffic will route through CSW1. On average CSW1 moves about 15,000GB of data around per month. The stock fans in this switch are very loud, so I have swapped out the fans to be much quieter while still giving adequate airflow.
Network: CSW2 (Core Switch 2)
The living room’s primary connectivity hub. Lots of room for expansion here. Mainly connects my primary desktop PC, the wireless router, game consoles, the TV and my Media PC. This switch is fan-less.
Network: CSW3 (Core Switch 3)
My apartment has CAT5e run in the walls to various rooms. That means that my server room essentially just needs to plug into the CAT5e wall socket for connectivity to the rest of the house. That is where CSW3 comes in. It’s located in the laundry room in a small network closet. This is also where the ISP coaxial cable feed comes in too. CSW3 is a rather robust Netgear GS108T-200NAS Prosafe 8 Port 1GbE Switch. It is basically the interconnect between the server room and the rest of the house. Home devices, wireless clients, and everything else from other rooms of the house will need to pass through here.
For primary wireless communication I use a Linksys WRT1900AC Wireless Router. I’ve replaced the two rear “ears” with a pair of high-gain omni directional RP-SMA antenna‘s for added signal strength and range. For cooling and stability it has it’s own dedicated Thermaltake cooling pad complete with blue LED’s! (because why not right?!)
