Speaking of which... anyone know why there don't seem to be any managed 2.5 Gbit switches / chipsets? Can we expect them in the foreseeable future?
The sub-enterprise, prosumer, SOHO-type market is pretty strong, but OpenWRT isn't a part of it -- not sure if that was a requirement.
Also has 280 watts of PoE. Goes for $700 or so.
The "home network with a NAS" is typically served with a small 4-8p 10G, while the 2.5/5G switches (particularly high density ones) are more of a bridge for orgs that have a lot of AP density and to get more out of that physical cable plant as they upgrade to WiFi 6e/7 devices on those existing wires. Gaming motherboards ship with up to 2.5/5, but again, how many switchports are needed for the SOHO market, especially when users can chain a few smaller switches together?
The price point for mostly/full mGig switches is almost an order of magnitude over what the prosumer/SOHO space prices at. UI offers a 48p but with only 16x2.5 ports at $1300. Cisco Meraki has 48p models with full mGig but that's $7-10k based on Google, and now you're out of prosumer/SOHO and squarely in enterprise platforms.
Ultimately, I do think such switches will pop up, but it'll be a little in the future as those enterprise dollars drive the cost of chipsets and transceivers down. Just not there yet to have that density at SOHO prices.
