Only around $225 was needed. If you had paid the current market price, you might have obtained the US-16-XG-US or 16-XG-US at a lower cost while keeping your SFP+ NICs. In those conditions it would have saved money. I think I found somewhere mentioning the XS708E has a more powerful CPU, making it better for routing tasks which supports its higher price. The Ubiquiti switches are mainly useful for switching purposes.
I have two SFP+ devices and one Ethernet module. The chips aren't even plugged in yet, and they didn't connect properly on the client side either, especially with 10GbE over Switch. They worked as DACs using Cisco transceivers. With a P2P setup there were no problems. From the networking perspective, that's all the gear I've got. The other devices are just two PCs and a NAS.
yeah, sorry, lol. No more switches, never got full speed out of the RJ45's. Neither through the switch nore p2p between two PC's That's the point that makes me question if it's really the switch. i'll do something weird now i think. I'll try to put a x540T2 on the same network together with itself and iperf it. That should theoretically tell me if the card is 10gbe capable at all, if it works.
consider using a single SFP+ switch with fiber connections instead of multiple NICs and computers. This setup simplifies management and reduces cabling complexity.
to plan future network expansion using longer distances via RJ45, I currently have a switch and just a single DAC cable. Recently, I connected an X540T2 to itself and discovered it can handle more than 10GbE independently. On my Windows 7 PC, it achieved 8.6-9.1Gbps with the same device. The two PCs only managed around 3Gbps together.
You can achieve much greater distances with fiber (up to about 10km using 10g base rate), and it's also more affordable than Cat 6e. Fiber is simply the current standard now. How are you verifying this? With two NICs on a single system? I’d be concerned the data isn’t actually passing through the NICs, which feels like an issue. Should I check the cables? What type of cables do you have? Does your Netgear switch include a cable test feature?
It seems there was a single NIC connected to itself within the same system. Possibly the data isn't passing through correctly. The new CAT6A cables are 3 meters long, and the switch includes a cable tester confirming everything is okay. EDIT: It might be the old 1GbE Intel driver for the onboard NIC that's causing the problem—not it.
You've made some progress but are still facing challenges. The X540-T2 with a Chelsio SFP+ card works consistently at similar speeds, around 390/330 MB/s, across different setups. However, one run saw a sudden jump to 540/360 MB/s that's hard to explain. On the Win 7 system, speeds are solid at 850/750 MB/s. You're considering testing other machines in Win 10 and enabling SMB1 in Win 10, but results remain unchanged. Taskviewer is hitting limits on one machine—no clear cause yet. Need more details or adjustments?
