.Hmm... They'll be going in the X10SLL-F in my NAS and the P330 Tiny-based Proxmox+Ceph cluster I'm building, so hopefully everybody'll get along...
No Issues with Supermicro X10SLL-F or Supermicro X10SLM-F or even Supermicro X11SLL-F, provided that you plug the NIC into the PCH/DMI/Chipset Connected PCIe Slot, for ASPM to work. But you'll be limited to 16gbps Total Bandwidth (X10SLL-F in PCH Slot), so either you enable Switchdev / Offload and/or possibly ROCE v2 if you want to switch/route between the 2 Ports and possibly saving on PCIe Traffic/Bandwidth (unsure how much Bandwidth would be saved by these Offloads though). PCH/DMI/Chipset Shares Bandwidth with SATA/Onboard NIC so you'll lose quite a bit of Bandwidth if you put it there. On the Supermicro X11SSL-F it's a bit better with up to 32gbps theoretical Bandwidth so if you don't use too much in SATA then it's OK. It depends what you care about: Speed or power Consumption ?

My 10Gbps (or faster) server NICs are never idle, and I suspect that this is true for many people. With even 3-4 running VMs where their storage is on the other end of the link, it's always doing something.
Sure, not 100% Idle, but maybe 30%-50% Idle and there from PC2/PC3 down to PC6 (or PC7 or higher) makes quite a bit of Difference I'd say.
turbostat e.g. turbostat --show Avg_MHz,Busy%,Bzy_MHz,TSC_MHz,POLL,POLL%,C1%,C1E%,C3%,C6%,C7s%,CPU%c1,CPU%c3,CPU%c6,CPU%c7,Pkg%pc2,Pkg%pc3,Pkg%pc6,Pkg%pc7,Pkg%pc8,Pkg%pc9,Pk%pc10,PkgWatt,CorWatt,IPC,IRQ,SMI --interval 0.5I haven't seen such problems on latest firmware. On earlier ones - it is hit-or-miss tbh, they even don't post on some consumer motherboards with really old firmwares.

Offered $20 ea. for 5, seller countered with $25. 7 remaining as of posting.
It was listed for $25.95 at the time I made my offer, and the initial post. Seems the seller raised the price since then.
Why not update the post title then?
what's high power consumption? 9 watts instead of 6? I think I'll survive lmaoNo Issues with Supermicro X10SLL-F or Supermicro X10SLM-F or even Supermicro X11SLL-F, provided that you plug the NIC into the PCH/DMI/Chipset Connected PCIe Slot, for ASPM to work.

Of, if you don't care about ASPM and Power Consumption / Temperatures at all, plug it into the fastest x16/x8 Slot you want, and most likely you'll be stuck at PC2/PC3 (Package C-State 2 or Package C-State 3) and high Idle Power Consumption
You'll see
. . Then the only one LMAO will be the Electricity Supplier
An extra 20 watts would be about 90 cents a month here, not that I'd notice it given my rack is currently at something like 930w. I can't imagine a cpu in a 10gbe machine would have the opportunity to go to sleep very often if ever, if I'm building a server or firewall it tends to.....do thingsYou'll see
EDIT 1: it's NOT (only) about the Power Consumption of your NIC. It's about the CPU NOT being able to sleep, so maybe 10-20W more on a Xeon E3 Platform ...
EDIT 2: So maybe you'll have 30-40W at the Wall instead of 15-20W (at Idle)
More like 10% idle for "storage" NICs.
