    Why can't we have home switches with 120mm+ fans in a 'non-pizzabox' type case?

    So the big problem with all 10GB+ switches today is the cooling, because they all come in 1U type format, which only fits 40mm fans. a 48 port traditional switch has 4x 12 ports sections horizontally. If they were stacked vertically, they could be in a case sporting a single 140mm fan. Or 2x...

    Hacking the intel H10/H20?

    So i recently bought a Orico USB-c nvme case off ebay that actually came with a 32+512GB Intel H10.

    EU REMOVED - went to metal recycling. Chenbro 3U 12-bay rackmount storage enclosure (probably RM31212)

    So this has been moving with me from place to place, sitting in storage. I have no use for it, since the 3U height doesn't fit a standard ATX PSU, it makes it too loud for home use. It's very old, about 20 years old i think, but in overall good condition. It has one PSU of unknown specs...

    My Proxmox/Debian systemd script for partitioning and detaching Solarflare SFN7x22F VF's

    EDIT: The original script i posted only works when partitioning interfaces for use with pcie passthrough in VM's. But i quickly ran into issues when i wanted to use interfaces for the proxmox host as well, because the script was being run after proxmox configures network interfaces, and starts...

    Big supply of Optane 900P 280GB U.2 drives from China, Anyone have experience or insight about them?

    Does anyone have experience with the hundreds of Intel 900P 280GB U.2 drives from china, listed on Ebay for about 150-200 EUR? Knowing they can fake almost anything, i guess the only way to find out would be to order one, check all info with Intel/Solidigm tools, smartctl, and then compare...
