Hi all, anyone have experience with Pine64 Clusterboard?
I was thinking about getting a couple, fully populate them
with SOPine A64 modules to buildup a network traffic
generator.

mlarkin@ has one. There was some kind of problem with the Ethernet,
not sure if that got figured out.
The backplane ethernet seems to be limited to 10Mbit unless you apply
a diff that kettenis@ has, and then you get 100Mbit. Gigabit never worked
for me, but apparently that's a known issue with these pine boards.
Other than that, it works fine. I don't know if the battery is routed
to all the RTCs though (never got that sorted out). And if you use
an ATX power supply instead of the 15A DC (barrel jack) power supply,
you need to solder in the dummy load resistors (these come with the
board).
If you're going to use it as a "network traffic generator", remember
there is only a single 1Gb/s uplink out of the onboard switch. So
don't think you're going to be getting 7Gb/s.

Serial is not muxed so getting at the console of each is a different
port.
My thought was to rackmount qty 7 dual mini-itx 1U cases, connect
them to a switch @1Gb with switch uplink @10Gb. Effectively a 10x
SOPine compute cluster. It sounds like I would need the kettenis@
patch. With kettenis@ patch is each module limited to 100Mbps,
with out from cluster @ ~ 700Mbps?
Controlling 70x systems is easy. I came into the industry when
serial dumb terminals were the norm, I like serial. Oh, yeah,
soldering is fun too. ;-)
