Hey forum, padawan here.

I’m trying to find the MikroTik CRS804-4DDQ-hRM switch in stock… anywhere… so I can set up my 4x DGX Spark founder’s edition cluster. The CRS812 seems to be completely sold out too. Both say backorders are expected to fill in November… but I have work to do untouchable from the larcenist hands of big AI and months is a lifetime away.

Anyone know a reputable place where I could get one?

Alternatively, anyone recommend another way to set this cluster up??

I’m non-technical trying to do technical things. It’s been a wonderful moving target for my curiosity but… just a lot. I’ll spare you all the long version of my journey and simply say - thank you.

Also to Wendell if you see this - you have my appreciation and gratitude
