My setup is really high end i just treated it like a gaming pc. Dream machine Pro Max connected to a POE Enterprise 48, that gives 2.5gb network to all the wired devices. Have one u6 pro and one u7 pro access points. Finally a 1u unvr which runs the 10 or so AI-Pro cameras.
Love my unifi gear.
From the top:
Dream Machine Pro Max - This has two HDDs but I’m not using them. I have redundant internet sources, 1G Cable and 2G Fiber. The dream machine can fail over between them.
2U Patch Panel
POE-Enterprise 48 - This is connected via SFP+ 10G to the Dream Machine and is where every device in the network plugs in.
UNVR - This has 4x 14TB HDDs and is where the cameras record. That covers more than 2 months of constant recording at 4K on the cameras - which are all connected and powered by the switch. This connects via SFP+ to the switch.
Unifi Remote Power - This is like a redundant power source for the switches and stuff so if the power supply failed this would pick up.
Unifi Power Strip - everything is plugged in here, you can toggle the ports and stuff on and off which I don’t do.
There’s a bunch of other stuff in the rack multiple piholes and little intel nuc servers doing stuff. Redundant piholes is a nice addition to the network though once you get going.
