Anyone try one?
Nope, those are separate.Ooh, that sounds interesting. No SFP at that price, I imagine, which is a shame, since I could use an SFP (not really plus... yet.) port.
I just heard about a 16 port 10GbE Ubiquiti Unifi switch for $300 as part of their beta program. Anyone try one?
connected with a TAP/Twinax Cable?I just got the switch hooked up and running with the T420. Things seem to be running fine. The biggest issues I've seen are optics incompatibilities.
10GbE half duplex does not exist.I have one and i've connected most of my homelab to it via mellanox connectx-2 cards. Some of the DAC's (cisco 3M) work, some dont. Its very finicky with DAC's, but SFP+'s work pretty well.
right now the only problem I have is connecting my main Freenas box to 10G. Its running the Xeon-D 1521 motherboard with onboard 10G ethernet.
I've never had them connect at full 10G as yet.
Does anyone know of a way to force 10G duplex in freenas ?
10GbE half duplex does not exist.
I guess you are running into this bug in the ixgbe driver which was fixed recently. The spaghetti media detection code didn't identify DA cables properly and the "duplexness" became undefined.

However, don't worry. The interface is running in full duplex although it's not described as such in the operating system. It will only affect LACP, which will refuse to work on an interface not marked as full duplex.
Oops sorry. I assumed that you were seeing something similar to what I saw on FreeBSD when using DA twinax cables. It showed media as "unknown" on ifconfig, and neither half or full duplex.Thats not what i'm asking this for.
I'm testing out some beta firmware on the 10G switch, hoping that it would finally connect to 10gbase-T ethernet connections. One of the other users confirmed being able to connect and maintain 10G connection on windows by forcing full-duplex and 10G in the connection. In other words, its not trying to auto-negotiate the connection.
Then something is wrong and forcing things, if it's even possible, is probably a bad idea. GbE and up must autonegotiate anything beyond 100Mb/s.I have one and i've connected most of my homelab to it via mellanox connectx-2 cards. Some of the DAC's (cisco 3M) work, some dont. Its very finicky with DAC's, but SFP+'s work pretty well.

It doesn't, much like was the case for 1GbE. All pairs are transmit and receive simultaneously.It's odd to need forcing full duplex on 10 GbE, unless I am very wrong half duplex 10 GbE simply does not exist.
Have you tried different cables? Different hardware at either end?I have one and i've connected most of my homelab to it via mellanox connectx-2 cards. Some of the DAC's (cisco 3M) work, some dont. Its very finicky with DAC's, but SFP+'s work pretty well.
