But I'm not aware of a value 400 GbE NIC. Mellanox ConnectX-7 400G costs more than 3x the CPU.
No, no, no. Fuck ASUS and you don't understand the use-case.
I acquire gear through gray markets just fine because I'm not paying zillions for commercial channel parts. I can get a 1 port 400 GbE NIC for ~$1k USD. It maybe used or an engineering sample, but it works.
AmpereOne EPYC
Kernel: 6.8 6.10
Wasn’t there sizable efficiency improvements just in the newer kernel that could explain some of this away?Some systems are even water cooling random little components for completely fanless 1U/2U servers... I wonder about the longevity of those systems though!
With the water cooling, you can pipe all that water out to chillers and at a certain heat volume it makes more sense than handling all the heat in air exchangers.
