Running Rosetta overnight.
Two doing bursts of Rosetta (CPU) and Einstein (GPU) work.
Pi3's running Einstein. Pi4's running Einstein and Rosetta.

The 2.5GbE switch arrived and is now plugged in. I put my two spare 2.5GbE NIC's into the Nvidia GPU machines.
I ordered (and received the following day) more patch cables as I use color coded ones. White for the 2.5GbE cabling to make it easier to work out which port they need to go in.
My order for more NIC's via eBay got cancelled/refunded. Apparently they were returned to the seller as undeliverable due to the mailing label getting damaged.
I made another order for different NIC's via Amazon which cost more but they are based upon an Intel i225 chip. The eBay ones are based on a Realtek chip. When they arrive I will swap some of the NIC's around.
After all this Einstein fixed their scheduler so that it doesn't keep issuing new data files. Apparently it was misconfigured which is why the large downloads. Its back to smaller downloads and I probably didn't need to upgrade the network.
