yes, they're just OEM mellanox cards. see here for flashing instructions: https://forums.servethehome.com/ind...net-dual-port-qsfp-adapter.20525/#post-198015
Just purchased the two 40g adapters and a couple QSFP+ to SFP+ adapters.. I will read over the flashing instructions. Any tips on the flashing?just imagine an intel nic, but better. kind of like that
Also, with the $75+ price of the 10gbE only cards, it's cheaper to spend $35 on the 40gbE versions like this: HP 649281-B21 Infiniband FDR/EN 10/40GB 2-Port 544QSFP ADAPTER 656089-001 ,New | eBay
or short bracket version: HP 649281-B21 Infiniband 10/40GB Dual Port Adapter Low Profile Bracket | eBay
then a couple QSFP+ to SFP+ adapters so you can use SFP+ in them GENUINE 655902-001 655874-B21 HP MELLANOX QSFP/SFP ADAPTER 886111656585 | eBay
you'll still come in under or at the $75 price of the 10gbE only cards, but now you have cards already in your systems that are ready to do 40gbE if you ever upgrade your switches/network
Can you provide me the details for the flashing and what Mellanox firmware I need to download.Those are OEM rebadged MCX354A-FCBT, they can be flashed over to standard mellanox firmware pretty easily.

I wonder if that might have something to do with why my gaming rig kept crashing with the CX3 in it. Although it's the 10GbE-only one, and I have decent airflow in the case. Maybe I need more. I thought Windows was just being really picky or that it didn't like the particular version of WinOF I'd installed for it (was trying the Win10 180x build of WinOF 5.50)Be aware of airflow with the 40GbE CX3s. I forgot that server hardware expects a minimum level of airflow/ventilation when I upgraded to a CX3 40Gb card in my quiet desktop and crashed pretty consistently after some hours until I screwed a fan onto it.
At least I found a use for that 6.3CFM Sunon fan that I never could get working in my 6450, heh.
Yeah, it took me several days to figure out what was going on. I couldn't reproduce the crash with any combination of loads but if I left it on for a long period of time I'd come back to find it hung. I screwed a spare 40mm fan into the heatsink and I haven't had an issue since.I wonder if that might have something to do with why my gaming rig kept crashing with the CX3 in it.

Are these the commands to flash the card on a Windows OS machine?Follow @fohdeesha's link above: https://forums.servethehome.com/ind...net-dual-port-qsfp-adapter.20525/#post-198015
It's really straightforward, the Mellanox firmware tools are great. I had no problem cross flashing two OEM CX3 cards and then modding a handful of CX2's to support RDMA/SR-IOV later.
Thank you. For myself (a newbie), good videos are so helpfulI highly recommend Terry Henry's youtube channel - he's a fastiron engineer at brocade/ruckus and posts a LOT of micro tutorials you can follow along. Some of the newer videos apply to fastiron v8080 only, but 95% of them apply to the 8030 codetrain the switches in this thread run. The brocadecampus youtube link above is a smaller channel that just occasionally reposts some of terry's videos

VLAN basics:
a couple videos on inter-vlan routing:
Video on LACP:
Video on named ACL's (which is the ACL type you want to use, the old cisco-numbered ACL types are being retired thank god):
I asked my question poorly: If there is a single Cat6 going from the Brocade 6450's Port#10 and going to an 8port Switch at the TV Media Center; and my desire is to put all the TV related devices (TV, Stereo, Tivo, Apple TV) onto its own VLAN.The Dell 2708 is a managed switch, so you can set up different VLANs for different ports, and have them all go over the same cable (i.e. trunk) to your basement switch. This is the primary use case of managed switches.
If this is your first time dealing with VLANs, you should remember to be conscious about which switch port is passing tagged traffic and which ones are untagged.
This is more a Dell Server T620 question than a Brocade question.The ConnectX-3 is a newer card revision and supported under current versions of Mellanox's WinOF drivers It's also a PCIe 3.0 x4 card, versus the ConnectX-2's PCIe 2.0 x8. That does give you more flexibility in regards to what slots you can install the CX3 into for the same bandwidth usage on the PCIe bus, but other than those points, there's really not too much difference if you're getting the Ethernet-only cards like the CX311A.
That said, I'm using ConnectX-2s in my FreeNAS 11 box, my R710 running Proxmox, and an HP server running Windows Server 2016 with no issues (though since I'm just using the stock drivers and not WinOF, I don't have the advanced features enabled on it like VLAN tagging) and they came right up on my ICX6610-48 on the untagged VLAN I set up for my storage network.
I am shortly getting a Dell T620 Tower Server, and the manual for it says I can use "Mellanox® ConnectX®-3 dual-port 40GbE QSFP+" ; on ebay I seejust imagine an intel nic, but better. kind of like that

You could use LACP to do link aggregation, or you could have 1 direct 10GbE connection to 2 other boxes, other than that you don't really gain a whole lot from having a dual slot card over the single-slot. It depends on your intended uses and how much bandwidth you think you'll be pushing total, to how many other systems.This is more a Dell Server T620 question than a Brocade question.
If I get a Mellanox ConnectX-3 dual SFP+ card and insert it into Dell T620 server; and run two (2) TwinAx 10gig cables back to the Brocade 6450 - do I gain anything interesting ? plan to try ESXi and Proxmox on the Dell T620 server as I"ve never run either one.
Mezzanine cards are typically used in blade enclosures, your T620 would more need something like this:I am shortly getting a Dell T620 Tower Server, and the manual for it says I can use "Mellanox® ConnectX®-3 dual-port 40GbE QSFP+" ; on ebay I see

Since Tower Servers and 40GB cards are new for me, I am used to seeing gold connectors on the bottom of PCIe cards; which this card seemingly lacks.
Just wished to confirm I was getting the correct card, thank you (will then be getting QSFP= to SFP+ adapters as I have a brocade 6450 and not 6610; but like the idea of future-proofing.
