Hello everyone,
the title says it all. We are currently planning the electrical system for our new build.
The electrician has planned a Hager “technical center” with a multimedia panel. This is where the LAN cables will terminate. Additionally, I would like to install the router and a NAS (Synology 214play) there.
It looks quite neat and seems to fit everything needed, but does this make sense?
Today, I was wondering why I wasn’t offered a server cabinet.
What are your experiences? What makes more sense? How does it affect the cost?
I would be very grateful for some advice.
Christian

iperf is quite reliable and simulates a file of any size, which also does not have to be read from a potentially slow hard drive.
The point is not that the switch cannot handle gigabit speeds in principle, but depending on how the routing is set up and how many new devices or hosts are involved, this can no longer be handled by the switch chip in hardware – and then it slows down because each individual packet has to pass the bottleneck at the CPU twice: once going there and once coming back. Additionally, the CPU is not designed for high routing loads. The switch chip is primarily intended for Layer 2 forwarding and can only perform limited routing in hardware through some workarounds.
Otherwise, it would be strange, because then no one would buy "real" routers anymore.

As a specific example:
My switch has a total of 28 ports, four of which support 10 Gbit/s. It can handle 64 Gbit/s switching in hardware and can also route at basic levels. However, for more complex routing, it only achieves just over 1 Gbit/s. The router, on the other hand, can switch only 20 Gbit/s but can route at 10 Gbit/s in most cases because its CPU is connected to the switch at 10 Gbit/s. This difference is noticeable and can also be proven with measurements.

I still think that an SG 300 in a small home network with accordingly few connected devices is not overwhelmed even in Layer 3 operation. I’m talking about an average home network. Not everyone has such a large network at home like @rick2018. So what do you have connected in your network?

Here’s a concrete example:
My switch has a total of 28 ports, four of which support 10 Gbit/s. It can switch up to 64 Gbit/s in hardware and can also handle basic routing. With more complex routing tasks, however, it only manages a bit more than 1 Gbit/s. The router, on the other hand, can switch only 20 Gbit/s but usually handle routing at 10 Gbit/s, because its CPU is connected to the switch at 10 Gbit/s. You can definitely notice that difference, and it can also be measured. What do you mean by more complex routing? It’s not a provocative question, just genuinely curious. In a single-family home, you usually have (if anything) just network a to b, network a to c, network a to d, maybe also network d to c to a.
In home networks, "complex" routing scenarios are clearly the exception ;-)
But usually, routing is not best handled by the switch anyway. Often, networks are separated to restrict access, etc., and in that case, the firewall also manages the routing.
If you find yourself thinking about broadcast domains and complex routing within your own home network, it’s probably more of an occupational hazard, and you’re better off with a "real" router^^
