We have a series of 13 Dell R610 hosts with ConnectX-2 EN cards running ESXi 6.7. We have been trying to get RDMA (more importantly the iSER adapter) to enable and show up, however we have been unsuccessful. RDMA is supported by the FW, as we had gotten it to show up before with different...

So, through much blood, sweat, and tears, I have my NAS and ESXi recognizing their new-ish ConnectX-3 cards in IB mode. I can send pings across the links and everyone looks happy. However, after adding my NFS storage to ESXi, I am now having another problem. Access to the NFS share from ESXi is...

Hello, We bought a used IS5030 switch from ebay. But only the top 18 ports can work and the rate is only 20Gb/s per port, even though we used QFP cables. It looks like a license problem. I found several numbers on the pull out tab. But it always shows Malform license key error when I tried to...

any help greatly appreciated... warning... n00b at this ... Ok so I'm new to this and I have a test lab at work. I have 4 esxi 6.7 boxes - will get to them later a windows 10 pc (dell precision 5810) Our guys were getting rid of a mess of hardware so I grabbed it and figured time to play...

Hi Folks, Anyone come across or try out a killer use case for RDMA / RoCE? I know there are custom builds of some hadoop based apps but what have you found to be a great use of this tech? I have the box, now need the project. :) James

Hey all, I used the instructions to cross flash two HP Connextx-3 cards QSFP to Mellanox MCX354A-FCBT's. I then installed two Fiberstore (FS) QSFP-BD-40G modules into one card configured as dual Ethernet. No dice, the link won't come up and the lights on the card stay off. Things I have...

I recently got two MNPA19-XTR Mellanox-ConnectX2 cards and installed them into my servers. I followed another thread on here and they are both running fw=2.10.0720, the vstat is here: hca_idx=0 uplink={BUS=PCI_E Gen2, SPEED=5.0 Gbps, WIDTH=x8, CAPS=5.0*x8}...

I picked up a Mellanox IS5600 and do not have any personal use for it. Total Newb when talking about commercial-ish switches. This unit taken out of a working environment. Retailed for $500,000 retail LOL. Seriously. Half a milli! Listed for $3,000 USD plus shipping. Paypal or local cash...

I ordered some SFP-H10GB-CU3M compatible (supposedly) DACs from fs.com, and although they're nice and thin, and work with my Mellanox Connectx-3 cards in my NAS', they are not compatible with my P81E 10GbE cards in my UCS servers. Can anyone recommend a good DAC in 3-5m distances to connect my...

I've been working on a Supermicro SYS-E300-9A (Intel Atom C3858,) putting together a fully virtualized router + whatever, and I'm getting around to being complete. The last step for me is routing my existing 10gbit setup through it, but I've hit a snag. My NAS has a Mellanox ConnectX-2 card...

Hi there all, I've just finished setting up a nice AIO proxmox server and between it and my workstation (direct connection), it saturates 10Gb or gives a faster then local SSD speed depending on work load (NFS maxes out at 4GB/s but thats a different thread)......and now I want more. Well not...

I got a bunch of these Mellanox ConnectX HP branded MT26448 cards on eBay for use in a Proxmox cluster, and mostly they're fine. However, once every 3 - 5 reboots, they don't come up and we see the this in the logs: I've found a few posts about this issue in various places, but none with a...

Hello! I have the opportunity to purchase some used dual-port Mellanox MCX354A-QCBT ConnectX-3 cards with VPI network adapter. (10 GbE Ethernet and 40 Gbps InfiniBand.) These would be perfect for my cluster after correct configuration.. They were originally pulled from EMC systems and...

My 2-port Mellanox ConnectX-2 NIC is running at a scary 72C. I have got a Norco 4u case with 6 Noctua 80mm fans. They are running at adaptive speeds. Nothing blowing air over the PCI cards, so that won't help. I might build a bracket with magnets to hold some fans (maybe two 80mm) and one of...

Good Afternoon everyone. You will have to excuse my ignorance when it comes to infiniband/ SFP/ SFP+ and QSFP. I have purchased two Mellanox MHQH29C-XSR ConnectX-2 VPI 10/40 Gbit Low Profile Dual-Port Adapter Cards for use in my home network (purely for learning purposes and for transferring...

Unbelievable deal! These are low profile dual port cards capable of 56Gbps IB and 40Gbps Ethernet. I messaged the seller and bought 32 cards for $25 each plus shipping. He said he has 1300 in stock so there's plenty for everyone :) They can be flashed from their HP firmware to stock Mellanox...

Hi, I'm having speed issues that I've isolated to my IS5030 switch. System: I have two Infiniband switches: 1. A Mellanox IS50XX with 36 ports enabled and the FrabricIT internal subnet manager running, making it an IS5030, with latest firmware (IBM P/N: 98Y3756) 2. A Sun 36 port QDR Infiniband...

Hi! I need a 10 meter active SFP+ DAC to connect my workstation peer to peer to a server with Mellanox Connectx-2 cards. I might get a TP Link SFP+ enabled switch in the future... so compatibility would be nice to have. Since the cables run for 81 USD new, which ones should be the most...

I missed the previous $80 CX-4 deal, but I found this MCX354A-FCCT CX354A MELLANOX CONNECT-3 4099 FDR10 40/56GbE 2 PORT QSFP ADAPTER | eBay Different from MCX354A-FBCT, the above one is MCX354A-FCCT (ConnectX-3 Pro)
