Since we design our own hardware, we put exactly what we want and need into them. We share some components like power, network, and casing.

This means for example :

- one integrated network switch/router for 18 servers; no need to buy an external cisco/juniper/whatever

- one dual power supply for the whole gang instead of 19 (18 servers + switch)

- less metal/plastic parts

We try to reuse hardware designs and software from one iteration to another when possible.

In short, we do have less "unneeded components". Equivalent designs (thinking at moonshot for example) are expensive, so to achieve same density it's more expensive to buy existing solutions than what we design & build.
