I was basically referring to any of these: https://cumulusnetworks.com/support/linux-hardware-compatibility-list/ And yes, they are are about 3-5 times more expensive than what you listed. > The cheaper ones i've found are the Cisco small business 350x/550x at about > 2000 euros reseller price (new) with 24x10gb ports and stackable. > > In my case, I'll probably go with these Cisco If they can handle everything needed (and with a small enough Ceph cluster they may very well do so), definitely. I couldn't determine it 100% from the docs, but it seems they might be limited to 32 LAGs per stack (so 16 dual-ported end nodes). Not a very small number, but then we ran into such a limitation with another project and Brocade switches when it grew (slightly) larger than planned. Also these switches seems to be lacking in the V6 department, again based on a cursory glance at their specs and docs.
