I have a couple VLANs and I wanted to set an upstream DHCP relay on them so I could point it to a DHCP server I'm hosting, but the switch is giving me an error if I try to enable it at all. This is said throughout when I just try to enable it or point it to a helper address at all, I can go...

I'm having issues routing from the switch to the router/ISP. I have 2 VLANs created to separate the Workstations and the Servers, and while Inter-VLAN routing is working, getting out of the switch and to the router is not working. I cannot create a routerport on this switch as it says the device...

Not sure if these Pro versions are still a thing but pricing is going wild. If you take more than 10x seller accepts 15US$ :oops: Hope they are genuine. If I'm not mistaken, these can do 56Gbps on IB. Mellanox ConnectX-3 Pro EN Netzwerkkarte (MCX314A-BCCT) 7290107197144 | eBay

Hi, this might be a dumb question but do ConnectX-3 cards support speeds like 2.5gb and 5gb in EN mode because, i have been looking into getting one for my server and want to know if i will need a more expensive switch?

Hi, I recently started to use the HP Mellanox QSFP+ cards (both 649282-B21 and 764285-B21) but I'm facing the issue that both ports on the NIC have the exact same PCI address (even the same function id). I wanted to use them for a VPP router but this does not work as DPDK can't handle this edge...

Hello All, We are configuring our Mellanox SN2010 switches and need to configure one of the SFP28 ports for 1GbE to connect to the Internet circuit in our cabinet. I don't see on the Mellanox datasheet explicit support for 1GbE connection - only 10/25GbE. We purchased several of these...

Hello, after long efforts, I upgraded my MELLANOX CONNECTX-2 MNPA19-XTR cards to firmware version 2.10.720. However, interestingly, iperf3 shows 6.55Gbits speed when copying files from my NAS Server (OpenMediaVAult 6.3 Debian 11) to my Windows 11 Client. However, when copying files from my...

I recently got some connectx-7 from local distributer that used to sell unlisted lab equipment from some of the big companyies. As the price was fair enough, i just immediately purchased it without further testing and evalutation. Unfortunately, when I tried to connect two of the NICs , I...

Getting rid of some miscellaneous equipment, let me know if you have any questions. 1. Mellanox ConnectX-6 CX653105A single port 100GBE QSFP28 PCIe 3.0 x16 - sold on eBay 2. Two Mellanox ConnectX-4 CX455A single port 100GBE QSFP28 PCIe 3.0 x16 cards with two CWDM4 LC transceivers - sold on...

I have an MSB7800 running 3.10.2102 code and it seems like the following config line at the end is being added and removed randomly. Does anyone know why this would happen? I have confirmation from the team no one is doing it manually and I am trying to get the configs into git for archive...

Good morning, We've had an SSD on our sb7800 infiniband switch fail, have installed a new drive with a cloned image from one of our other identical switches. So far everything looks ok in the management interface, aside the Host ID. Though we do get 1003, 1006 errors when trying to modify...

https://www.ebay.com/itm/314167641289 Looks like it was discounted to $12 few days ago. Which is an attractive price for EDR DAC. From quick research MCP1600-Exxx should support 56G Ethernet and FDR 56Gbit/s IB both. Ordered 4 for myself.

Hello, Can anyone help get me the mellanox onyx installer for this switch? It seems like it is booting to ONIE and has no NOS. Does anyone know about this model? I cannot seem to find it in the documentation—its mfg date is from 2020.

None of Nvidia's WinOF drivers support Windows 11. I tried to install a Win10 driver and it gave errors, like 1719 "Windows Installer service could not be started." Upon trying to close out the failed installation, I can't even close it, it gives 2732 "Directory Manager not initialized"...

Hi, I'm using ConnectX-3's to implement 40Gbit networking throughout my home, and one of the important nodes is the HTPC. As you might imagine I think that it would be swell given the lack of HDMI-CEC on Nvidia to be able to boot up the PC without getting off the couch. The first step for that...

What are the difference between these and the -FCBT? I have some 354A-FCBT and -QCBT dual port NICs and I like them because they work and I'm familiar with their management now. I have need for the even smaller profile single slot QSFP+ cards like the above, which I see on EBay, and I'd like to...

Hi All, I'm currently in the planning phase of setting up a lab using 2 Proxmox hypervisors connected to 3 Ceph storage hosts. I wanted to get everyone's opinion on what is considered the best NIC value or otherwise to connect these servers together using a pair of ICX 6650's that I have. I...

Hey folks, I have 3 servers equipped with the Connect-X2 MT26418, all running Proxmox (debian11). The cards are all 2 Port ones, and I got 2 cables running between them like this: +---------------------------+ | serv1 | +---------------------------+ | Port 2 |...

Quick question: Has anyone had any success with 40G LX4 transceivers in Mellanox CX3 cards and SX6036 switches (specifically Juniper QSFP+ 40G LX4 LC transceivers)? I'm about to run optics throughout the house, and MTP/MPO cables are so much more expensive than LC/LC cables for multiple runs...
