I welcome a correction, but my understanding is that the X540 are needlessly toasty - even by 10Gbe NIC standards. Maybe take aim for the X550 instead?
I’ve read this a lot, that X540 runs really hot the the point the connection can end up throttling and killing the 10Gbit speed.
Mellanox connectx-3’s are wonderfull. Mine may be a counterfeit, I have no idea, but it works great and runs cool. Only downside is the cards limited support for sleep. The card is low power in it self, but it will keep the cpu from going in to lower levels of rest during inactivety. So keep that in mind if you plan to use it for something that idles a lot.
I want my current server and the upcoming nas to go into idle as much as they can, every other equipment won’t have to since they’re personal computers, so it will be 2, maybe 3 machines max into sleep mode or high idle status.
What’s the goal? Purge gigabit, or keep some connections? What connections and why? How many machines, and what kind och PCIe slots ( lanes and version) do you intendent to use?
I want to bring every room in my house to 10Gbit. I can’t purge all 1Gbit devices because some can’t be upgraded to 10Gbit (TV, brother’s iMac, Raspberry-like devices, etc.). I got an offer from a local isp for 10Gbit internet speed for 25€/month or 1Gbit for 20€/month and want to lay the ground for every device that can be upgraded to support 10Gbit in case i take the offer.
For now it will be just my server (A Lenovo M83P SFF, according to Lenovo’s data sheet both PCIe can draw up to 40w, one is 3.0 x16 and the other is 2.0 x4) and my personal computer (Mother board is a GA-B550M-DS3H, I’ll use the bottom PCIe which is 3.0 x4). I plan to build a new NAS next year and possibly a network machine for pfSense, net-wide adblock, VPN, etc., i’m currently educating myself on the topic so i might integrate everything into the Lenovo or just buy a specific machine designed for networking.
