A Linux server with an Intel 82599ES 10-Gigabit SFI/SFP+ controller showed no 10G interface and dmesg contained failed to load because an unsupported SFP+ or QSFP module type was detected after an untested SFP+ module was inserted. The article explains that the ixgbe driver only enables modules it…
The storage box went from Core 13.0-U6.7 to SCALE 24.04 and then on to 24.10, and ever since one port is crawling while its twin on the same card is perfectly happy. The 25G card behaves the same way, which is what makes me doubt my own eyes. Intel X520-DA2 with Intel multimode SFP+ optics, 10G to…
I run a small Proxmox box at home and wanted a proper 10G path to the storage node, so I dropped in a used Supermicro AOC-STGN-i1S. It is the plain Intel 82599 design, board marked E157872, and I assumed this would be the boring part of the build. It is not. Supermicro AOC-STGN-i1S, Intel X520-DA1…
We are consolidating a pair of R630s onto 10G and the cabling to the top of the rack is copper, so instead of pulling fibre I put 10GBASE-T SFP+ modules into the X520 cards. The switch end takes them without a word. The servers refuse to. Dell PowerEdge R630, Intel X520 (82599), dual port FS…
