Gigabyte MP30-AR0

This is the Gigabyte MP30-AR0 which now forms the top “layer” of my cluster (I had to retire one of the AMD boards in order to scavenge the RAM for this).


The Gigabyte uses the APM X-gene1, which is an 8 core ARM processor. This is rather old now — I’ve had a Mustang at home with the same processor for a couple of years now and the chip design itself is 3+ years old. It uses Cortex A53 cores. Even APM have a newer X-gene 2. Nevertheless it has two very big advantages over the alternatives:

  1. You can actually buy it. I had this one shipped overnight from UK supplier Xcase.
  2. It’s (sort of — see below) server class hardware, unlike the very cheap but ultimately crap development boards based on phone chips.

A particularly annoying thing at the moment is that Gigabyte are claiming this board is SBSA compliant, but then they ship it with u-boot as firmware. However UEFI firmware can be downloaded, see this thread, so it should run RHEL.

Here are the boot messages to the u-boot prompt:
