I just purchased an IBM Mellanox Connectx-3 Pro (IBM EC38 10GB 00RX859 00RX855 ConnectX-3 Pro CX312B). I am trying to use it in a windows 11 machine with a ryzen 5900x in an MSI MAG B550 motherboard. The card is installed in a slot that is running at x4. The card does not show up in bios or...

Hello folks! With the recent updates on Mikrotik RouterOS 7.15 they’ve introduced support to PFC and ECNwhich are vital to enable RDMA with RoCE. I have a setup of 3x servers with a pair of Dual 25GbE Connect-X 4 each (which supports RDMA with RoCE v2). I’d like to use two ports (one on each...

I picked up a pair of Dell-branded Mellanox ConnectX-5 MCX512F-ACAT dual-SFP28 NICs on eBay and have been trying out different combinations of transceivers I have on hand. I'm using Linux 6.10 (mlx5_core kernel module) and systemd-nspawn to claim one of the ports so that I can run, e.g., iperf...

Hello, does anyone know where you can purchase the SX6036 license for ethernet?

Hello, I have seen the incredibly cheap Intel 100G transceivers linked here (somewhere). Only problem is that shipping to europe is 30€ + taxes so the $5 seems less nice after that. I instead bought a set of Kaiam XQX4002 from France. (lot 2x KAIAM XQX4002 100G-CWDM4 QSFP28 100 Gb 1310nm 2km...

Hi all! I'm trying to configure MLAG to a pair of Mellanox SN2410 as leaf switches. I would say this is my first experience with the model and even MLAG configuration. It was configured based on this docs: MLAG I've done the config and everything looks great on the redundancy and fault...

Hello folks! I've create a 2-node Windows Server 2022 cluster for Hyper-V and Storage Spaces Direct. Each node has a ConnectX-4 dual 25Gb. One of those ports are connected directly to the other node on 25Gb mode and is used for RDMA on the S2D storage traffic. The other port is dedicated for...

Bought two Mellanox SN2010 switches Summer last year and they are working wonderfully. Reached out to Mellanox at the time for a service contract so I get switch OS updates and called them, emailed them, then called them again, then emailed them, then ... well, you get the idea. So far I have...

Good afternoon, everyone! I've searched through the forums but haven't been able to find an issue like mine. I recently purchased a couple HP 649281-B21 infiniband/ethernet cards off ebay, along with both a generic (Blackbox) 10m AOC and a Mellanox branded 3m passive DAC. The NICs were...

I use a 10Gtek 1 (1.25?) Gb RJ45 to SFP+ transceiver (from amazon) and a SFP+ to QSFP+ adapter (ebay listing title was HP MELLANOX 655902-001 655874-B21 QSFP/SFP ADAPTER) to connect my LAN switches (going through one unifi switch flex mini powered on USB-C to reach my router) to my SX6036. I...

I have two MSN2410-CB2FC units that the managment ports are not working. The port shows that they are up and enabled even though no cable is plugged in. when a cable is plugged in DHCP doesn't work, and no lights come on for the port. I have set the IP for the managment port staticly as well...

Hi, I recently got an R86s U2 but I'm having trouble getting the SPF+ interfaces to work. I can see the three 2.5Gbps interfaces but not the two SFP+ ones. $ ip l | grep -P '^\d' 1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN mode DEFAULT group default qlen 1000 2: enp1s0...

tl;dr - I'm trying to connect a ConnectX-4 MCX4131A-BCAT to a ConnectX-3 MCX354A at 40GbE. My Kaiam XQX2502's only seem to negotiate 1GbE. Is there a transceiver that will get me back to 40Gbps? Previously, I had two ConnectX-3 MCX354A's connected (Windows to Linux) with Kaiam XQX2502's linked...

For my setup, I already have (4) CX3 non-pro cards. I needed to get a single CX4 card in order to support the mlx5 driver that is now bundled with macOS and my macs can be on the network now via thunderbolt. I am interested in setting up a simple point to point network at home where the...

have a Mellanox SX6036 switch that's currently set up in InfiniBand mode. I'm interested in switching it to Ethernet mode for our network needs. Has anyone gone through this process before? I am going all over the Internet, and I cannot find it. Thanks!!!

[EDIT] After 2+ more hours I think I have found an answer. Nope. Every article I see talks about compatibility of using older 40Gbit QSFP+ optics in 100Gbit QSFP28 switches. Does the opposite work? I doubt it, but it would be good to know. I'm on a shoestring budget and I'm encountering...
