Clusterboard onboard switch

[Zyklone]

Dear community and team,

I just recently stumbled upon the sopine A64 and the clusterboard and think it is a great alternative to the traditional pis (orange, raspberry, etc.) and especially with the clusterboard you get a very neat cluster-design.
I am looking forward to building a skyminer for the skywire network with this, but would like to know a few additional things, before purchasing.

Especially regarding the onboard switch, I am a bit confused as to what specs / speeds the clusterboard offers.
Does it really offer full gigabit connectivity for each compute module at the same time?
In other words, is the switching capacity really 16Gbps?

I would be really thrilled to get some more information on this, since a colleague pointed out, the "onboard switch" might not be, what it seems to be. Although I doubt this is the case, I still want to make sure, I have full gigabit connectivity at every compute module and of course also on ethernet port (and all that at the same time -> 16Gbps switching capacity).

Thanks in advance and have a nice weekend

Best regards,
Zyklone
