Inexpensive 2.5GB switch?

Post by powerful owl » Tue Jun 30, 2020 2:22 pm

Hi, are there inexpensive 2.5GB switches? Or do people just jump to enabling their network for 10GB? Any pointers on the best route to start upgrading (one H2+ on the way) appreciated.

We could buy a 2.5GbE 8 ports switch at ~$150.

But it seems to be available in Korea only. :(

Netgear GS110MX
2 port 10Gb + 8 x 1G are around 160 EUR https://amzn.to/3dK0Tqu, didn't find anything cheaper ...

I upgraded straight to proper (but unmanaged/dumb) 8 x 10Gb Netgear XS508M ... there is also 5 x 10Gb (350 or 280 EUR)

Here are some models which I called "5-leg sheep category" or "obscenely expensive":

5-leg sheep category
Usually Has a bunch of 1 GbE ports + Limited number of 2.5 or 5 GbE ports and/or uplink 10G SFP+ or 10G-BaseT (RJ-45) ports.
Most of the times these are "edge" switches enabling you to connect a few computers on a local net and connect the whole thing to higher bandwidth trunks with the uplink ports.
Example:
https://www.amazon.com/12-Port-Gigabit- ... B084MLC83G $149.99
IMHO: this one is unusable for the purpose of connected several systems to the H2+ given it only has 2 x 2.5 GbE RJ-45 ports. Transforming a 10G SFP+ into a 10GBase-T will cost you around $55 for the transceiver.

Obscenely expensive
Usually managed switch with Web-based, serial or SSH admin interface. Options such as LACP, VLAN and so on.
Plus the artificial markup because it's "new" and multi-gig.
Example:
https://www.amazon.com/TRENDnet-2-5GBAS ... B079Z2SHCX $449.99

Tips
The switch you want (or not) and the budget for it depend entirely on what you would like to do. For instance: if you are going to use max 3 computers/SBCs over 2.5 GbE, have a dual port on one of the system (like the H2+) and connect each system to one of the ports. Done. No need for a switch. For 3+ up to 8 nodes, yes you need a switch (sadly current prices are: $500 - $800). For more, e.g. 16, 24, 36, 48 ports: n x $$$$.

If you're planning to bond the two H2+ ports, you'll need a switch with LACP.
