There are 21" racks in use at some hyperscale clouds with OCP

Traditionally, 23" racks are for batteries and behemoth class network gear chassis.

Another form factor: In telecom, 23" two post racks are common. Very handy to be able to get to both front and back ports, plus top access from the ceiling for the grounding and other wacky stuff that telcos use

Post author here: happy to answer any questions!

I don’t have a home lab, but I do have my ONT, a router, an AP, an 8-port switch connecting a bunch of devices (Phillips hue hub, Lutron hub, Apple TV, PS4, and Nintendo Switch) and it’s all just a jumbled birds nest of Ethernet cables - congratulations on having such a clean and organized set up!

My UPS, home network, home server, and some Raspberry Pis are all packed onto an Ikea Kallax, and if you look in the jumbled nest of Ethernet cables you may even see them.

I've looked into 10" racks before but came to the same conclusion - I'd either have to pay a bunch to get them in Canada, or put the work into tracking them down.

On the flip side, I did steal some K'nex from the kids so modem and router could stack with room to breathe, and I think that's pretty awesome.

Germany: I got my 19" network rack from a local electrician's overstock. He said 10" is much more popular for a lot of small installations at home or small businesses these days; hence he was eliminating some 19" stock.

With the 9U rack sitting mostly empty I can understand that. Except I'd be having a hard time fitting the 19" PoE switch into a 10" rack.

The wireless performance is likely compromised as a result of the AP having metal walls surrounding three sides of it.

Usually the UniFi dome APs propagate their signal in a kinda bubble shape up and out. I think he should be OK unless he’s on a top floor.

UniFi has an app called WiFiMan that’s easy to use for checking signal strength.

The bubble shape still is affected by his setup.

I had the same complained and would not put my AC in such close proximity to metal sheets.

It would also be an easy fix to just turn it around and put the AP on the bottom after rotating the metal frame

Perhaps a better way to put it would be to flip the top shelf upside-down.

Or just run some cable and don’t put the AP on the rack.

Lots of Video and Audio Devices come in 1/3rd and 1/2 rack sizing, this would be good for Blackmagic Ultrastudio type devices. (8.27" wide and need airflow side to side)

I’ve been looking for something like this as I anxiously await the delivery of my TuringPI

How big are the internal compute sleds at the hyperscalers? They use OpenRack and then subdivide them right?
