Hi!

Here at CERN we do not have separate Ironic controllers for ARM,
but we do not use the standard Ironic tftp setup either: we have
an "Ironic external" PXE/tftp service we rely on. What you will need
to make sure, though, is that you indeed serve architecture dependent
files via tftp. If I remember correctly, we do this via the architecture/firmware
information that is sent with the initial DHCP request, and an if statement
somewhere :)

(We should write a blog post with all the details, but I am happy to
dig out the details on how this works before -- if you think this would
be useful for you?)

Cheers,
 Arne

Subject: [ironic]Could I use x86 ironic to deploy arm bare metal node?

Hi,

I deploy ironic in x86 env, could I use it to deploy arm bare metal node?

My concern is mainly whether the files transferred in the tftp phase
of PXE cannot be cross-architecture.

Do I need to deploy a dedicated arm-architecture ironic-conductor node
for arm-architecture bare metal nodes?

Thanks
