In the forum, there are instructions on how to install deltasql server on a Raspberri Pi 3:

The Raspberry Pi consumes only about 5W of power, running it through the year means a lot of savings compared to a normal server which consumes about 500W of power.
This means deltasql server runs on the Apache and mySQL, which in turn run on an ARM microprocessor. In other words: it is possible to install deltasql also on your cell phone :-)
