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...

Thanks @i386 - I will go with your advice. :)

@i386 More reading shows that I need a 1000BASE-T transceiver. In your opinion, would this one work? https://www.fs.com/products/147159.html I also don't see any option to purchase a Mellanox-specific model - is this required and if not, which vendor-specific model should I specify...

@i386 Many thanks for pointing this out! Question - can I use this transceiver or do I need specifically a 1000BASE-T transceiver for this purpose? Hoping to order what I need this afternoon.

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...

Once again - thanks @ano !!

So all the shiny new toys have arrived - Mellanox switches and 25GbE network cards for our servers - now I need to order DACs. It was recommended by some very helpful folk on this forum that I purchase DACs (all connections are within a single cabinet) from fs.com, but this link only offers...

No vSAN @ano - all servers have directly attached (NVMe) storage.

Thanks for the input @bitbckt - I’ll stick with Mellanox as far as possible.

@ano @bitbckt Here are some links I sent to our hardware vendor for the SFP28 cards requesting pricing. It seems that I am required to go with a SuperMicro card for the hyperconverged servers (4 nodes, 2U NVMe) we use. I will avoid the Broadcom options as advised - this email went out before I...

Wow - that's really good to know - thanks @ano !!

Yep @bitbckt - I will be doing the physical server and network cabling. I have put a job out on Upwork.com to get help from an experienced network engineer to assist with the MLX switch and pfSense firewall config. Trying not to be concerned about bringing a complete stranger into my network...

Thanks @ano - I'm trying to wrap up my ordering spree and all this info is really helpful. Good to know about the possible speed/duplex requirements when mixing SFP+/28. Hopefully the MLX-based SFP28 NICs will be available off-the-shelf. Really, REALLY appreciate all of the help and guidance...

Haha!! I pretend LOTS of things don't exist in the full-stack software development and compiler world. LOL @bitbckt - Lovely! Thank you again.

Again - thank you @bitbckt !! I remember someone much earlier in this thread referencing that I shouldn't assume that SFP28 would correctly auto-negotiate with SFP+ even though compatible, so this gave me pause. I'm actually planning to make a clean sweep of it and replace the NICs in our...
