Is there any hardware upgraded switch to replace this model crs312-4c+8xg? It seems that the hardware configuration is a bit outdated now. At the same time, improving the fan noise may make it more suitable for home use.
I want the same network 10g electrical and optical ports, and the hardware is upgraded, and the fan noise is improved. Does anyone have the same request as me?
Apart from the fan noise … I don’t get what on hardware is to be upgraded, what is outdated? Device features 4 optical ports and 8 RJ45 10Gbps ports … (or less optical and more electrical ports since those are combo ports). And the switch chip, around which the device is built, is a pretty decent one.
Have one in my home, 3 meters away. Can’t hear it.
Have you set the fans?
I disagree. Can the hardware manufacturing process five years ago be the same as it is now? If it is sufficient, there is no need to upgrade the computer. And the price is still as expensive as when it was first sold. Hardware upgrades will bring performance improvements, reduce power consumption, improve heat dissipation, and reduce fan noise.
I can understand your thinking. However in networking gear, things don’t go the same pace as in general processing. Switching is typically done wirespeed on ASIC level … since it’s wirespeed, speed increases don’t happen (unless it’s supporting newer generation of interface standards). Yes, power consumption for switching traffic can get lower. And yes, there is definitely room for improvement in power consumption of multi-gig RJ45 ports.
But that’s about it … all one can hope for from a newer device is a slightly lower power consumption (allowing for quieter fan operation or passive cooling even). From functional point of view, everything might stay exactly the same. IMO we won’t see a new model replacing existing one only for power consumption reasons.
i have a CRS312 and i don’t really understand what could be “updated” to improve it.
yes, the fans can be a bit loud, i replaced them with Noctua fans for home use and that works fine.
what else would you want to change?
From what @Channing wrote I’d say he’d like to see “maximum power consumption” go from 60W (specified for current device) down to … uhhh, 30W? (Not sure if such reduction is realistic though). And I’d add “increase flash storage to at least 32MB if not 64MB”.
Personally I don’t really get the urge for quiet fans in a rack-mount device. If we were talking about desktop (-in) device, then I’d support this whole heartedly. Yeah, I get it, MT doesn’t produce passively-cooled devices with functional overlap with all the -rm devices, but then if silence is a requirement, one often has to compromise on something else … or do some mods … And I guess @Channing is not really asking for updated CRS312-4C+8XG-RM, he’s asking for a passivelly cooled CRS312-4C+8XG-IN (or something like that).
Adding a 100GB port would make sense at this time… (after all, they have a 100G “core” switch with the CRS504-4XQ.
If you have 8 devices with 10GBE connected, a 10GBE connection to the backbone is a bit limp…
