    MNPA19-XTR Connectx-2 / Windows 10 - Slow LAN download speed

    I use the same cards and similar 2 computer setups and Fiber connected. I'm having similar issues with it peaking at 7Gb/s. I did a few things below and got it to 9.5Gb/s, but it hasn't survived a few reboots, so I'm trying to troubleshoot that. Mellanox Drivers. Get 5.50 drivers, March/2019...

    Mellanox ConnectX-2 Firmware

    @Mistb0rn for me, I was getting this message after trying to burn the .mlx file with the .ini file: .\mlxburn -fw fw-ConnectX2-rel.mlx -conf test.ini -wrimage test.bin -I- Generating image ... -E- File: C:/ConnectX2/test.ini, Line: 1 - Invalid syntax -E- Image generation failed: child process...

    Mellanox ConnectX-2 Firmware

    does the core firmware file: fw-ConnectX2-rel.mlx, contain the boot ROM that comes with these cards. I've already dumped the .ini config information from the device, and will be joining it to the .mlx file to make the .bin, but was just curious about the ROM issue. Thanks.

    Enable 56GbE on HP-649281-B21 / Mellanox 354 with direct connect?

    Is there any problem running optical transceivers and OM4 in a peer-to-peer connection for 40Gbe traditional-ethernet? I'm sure this will eliminate IB connectivity. But still, I wonder if it's possible.

    HP 649281-B21 ConnectX-3 VPI MCX354A-FCBT $35 + $8 shipping OBO ebay

    I think I'm getting it. qsfp14 = 4x14Gb/s = 56Gb/s IB (proprietary Mellanox) FDR (Fourteen Data Rate) per channel. You made me do some homework/research.. Thanks.

    HP 649281-B21 ConnectX-3 VPI MCX354A-FCBT $35 + $8 shipping OBO ebay

    It'll do 14Gb/s? so, if that's true, then its only slightly better than a single port 10Gbe SFP+ card. I'm still unclear if it will ever be able to do 40Gb/s. Am I able to install QSFP+ transceivers in to get the 40Gb/s speed? I'm just talking Ethernet, not IB. I'm only interested in...

    HP 649281-B21 ConnectX-3 VPI MCX354A-FCBT $35 + $8 shipping OBO ebay

    wait a minute, is the 649281-B21 card a 40Gbe card? Shouldn't it say QSFP+ Instead its labelled "649281-B21 HP Infiniband Dual Port FDR/EN 10/40GB 544QSFP Adapter " if its QSFP, then it maxes out at 4Gb/s. If its QSFP+ then its a true 40Gb/s card.

    2 NICs: 1Gb & 10Gb

    Thank you guys Both ways worked, I tried both methods @beaker - I adjusted the metric to '5' for the 10Gbe connection and '400' for the 1Gbe NIC. It favored the 10Gbe for file transfers. @Balteck - I adjusted the host file to link the 10Gbe NIC to the specific computer name. It favored the...

    Switch recommendation: Smart/Managed gigabit, SFP/SFP+, homelab use

    Does the PowerConnect 5524 switch allow for fiber media? I have LCtoLC OM3 fibre in multiple areas around the house, all converging in the office/server room. The big question is, can it accept fiber connection (with the proper transceivers of course)?

    10G fiber noob questions

    I'm using LC to LC OM3 Fiber Patch Cable Multimode Duplex - 10m, with Finisar FTLX8571D3BCL transeivers (850nm), with 2 Mellanox ConnectX-2 single-Port MNPA19-XTR in a peer-to-peer. I haven't chosen a good switch yet (thinking about the Quanta)
