Cerberus - about

Postby ivelegacy on Sat Mar 23, 2019 11:59 am

Cerberus is a monstrous watchdog with three (or in some accounts four) heads that guarded the entrance to Hades.
This project comes with four PPC nodes connected to six sATA hard drives implementing a multiservice network attached storage.

It shares the following with the Sonoko project:
  • uboot's profile &patches
  • machine description
  • devtree
  • kernel
  • minitoorfs
  • sysboot

a few pics, once assembled

Postby ivelegacy on Tue Mar 26, 2019 12:09 pm




The 405 boards have a PCI riser and are stacked on a polycarbonate frame using metal spacers.
An eight ports LAN switch has been put on the top of the stacking structure.



The transparent chassis provides a lot of space inside for accommodating all the gears comfortably.

the motherboard

Postby ivelegacy on Thu Jun 13, 2019 10:33 am



We have recently bought a second motherboard. Having two boards is useful for having more person on the hardware remotely rather than having the need to meet somewhere to work all together on a unique board.

Small nodes have the same PPC405GP chip, configured in the same way. So it's really super helpful!
