I agree that 90% of people do not need that, but there is a scale between 1 machine and 1 million machines.
It is not just IOPS but latency. Some of my production servers are connected one-to-one by crossover cable, in clusters with as many extra nics as needed (say 3 machines: 2 extra nics per machine) just to shave that little extra overhead of going through a router as yes, it matters in some applications!
- SomeHacker44 8y agoTry using fiber then. I was surprised and pleased to learn that my 10G fiber has something like a third or quarter of the latency of my 10G copper in my new house.
- snuxoll 8y agoYou mean use (X)SFP(+), not “use fiber”. The SFP+ copper twinax cables I use in my lab at home have lower latency than the majority of MMF/SMF transceivers on the market.
- SomeHacker44 8y agoYes, thank you for the clarification/nomenclature. My SFP+ on MMF (multi-mode fiber) has significantly lower latency than the copper 10GbaseT I use. I haven't measured the direct-connect copper (coax? twinax?) SFP+ latency, though. I would be curious if the SFP for 1G using fiber also has lower latency than copper 1000baseT.
