FWIW, we had to have the idle speed of our fans lowered because the usual idle of around 5k RPM was WAY too much cooling. We generally run our fans at around 2.5kRPM (barely above idle). This is due to not only the…
We do not put the onus on customers to tolerate data loss. Our storage is redundant and spread through the rack so that if you lose drives or even an entire computer, your data is still safe.…
This is how our rack works (Oxide employee). In each power shelf, there are 6 power supplies and only 5 need to be functional to run at full load. If you want even more redundancy, you can use both power shelves with…
It’s certainly possible someone did a BOM substitution and didn’t due diligence on it, but I doubt it. PCB assembly houses tend to notice components that are suddenly too big for their pads because they’ll have fallout…
As someone who designs circuit boards professionally, the explanation is clearly lacking. There might be a thermal issue or there might not be. There is nothing conclusive in the pictures either way. What I do see is…
The NIC is a chip-down Chelsio T6 ASIC with 2x100GbE ports, one going to each Ethernet switch in the rack.
My apologies, this was not intended to be inflammatory but the quotes out of the article and the comments were raised to point out that these kinds of baseless and biased comments from the author detract from the…

Timing adjustment per x number of data bits has been required since DDR3 but DDR4 also has internal reference voltage calibration for DQ bits (VREF_DQ). This voltage sets threshold by which the IO cell determines if a…
The regulators are actually quite sophisticated and have many undocumented registers that set how things like the communications with the processor work, nonlinear control algorithms, etc.
It also turns out that not many people have 3-phase power and can support a heat/power load of 15kW in their homes ;)
