What a BEAST! I'm glad that you guys went and showed this off. I got trolled by a guy suggesting that I use infiniband (which I'm already familiar with) at home on one of my recent comments. I also understand that it is a total BEAR to set up and get running at the correct speeds, etc. Totally NOT the sort of solution I'd be considering for home use. I've seen other KZfaqrs try to install old used enterprise infiniband gear in their home, and it's always funny to watch them suffer. Too bad you didn't show all the fun bits of yourselves wrestling the bear. Although, it's not very exciting for non-nerds to watch. I'm surpised you could even power this thing. You'd need to build an internal Chernobyl just to spin up the fans, alone! (Exageration intentional for comedic effect) I'm afraid the electric company would send an investigator if I installed this in my home.

At my work, we are refreshing a dc and where 400gig fits for us is more in the spine to super spine/core layer. We just don’t have hosts doing that high of speed, but most are moving from multiple 10gig connections to 25s. I would be jealous when there is a need for direct host 400gig!

@I4get42 Жыл бұрын

Hi Patrick! Very cool. I mostly think of 400gig switches as core/ super-spine switches. But like you said, I could see it being great for breaking out into a LOT of 100gig links without any over-subscription between them. It is odd to think of 400gig as kind of slow, but if you had a bunch of 32 port 100gig switches with a 2 port lag up to the 400gig switch, that is 3200 down and 800 up. So about 4 to 1 oversubscribed uplinks. If instead you could break out a lot of 400gig ports into 100gig, and go straight to the server, there is no oversubscription between all of the connected servers.

@autohmae Жыл бұрын

When you mentioned core, I thought: I think most large companies use routers as core. So I looked up the product and it said right in the title: "64-Port Ethernet L3 Data Center" So yeah. It's also always fun to see in the spec sheet they mentioned Ansible supported in the automation tools. But what is interesting it supports RDMA over Converged Ethernet as well. Which is something I wouldn't have seen many years ago. L3 and RoCE in the same box (a switch would do just L2 and RoCE or a it was a L3 switch). My guess is it's a lot more common these days.

Just more awesome, cool content from Patrick K & STH. Yes it's nerdy. Of course it is! We learned about Mikrotik's 4 port x 10Gb switch here from STH years ago and other OEM 25Gb & 100 Gb switches, too. Where else can you see an FS 64 Port x 400GB switch under the hood. You can count on Patrick. He will remove tell you how many screws it takes to get inside the device. And PK will remove the Heat sink, the CPU, the Fan Modules & PS Modules every time. And you get discussion, use ideas, performance results, connections parts, etc. It doesn't get better than that.

Wow. 9% difference in throughput between ETH and IB. On 100 Gbps IB, the difference that I measured was only about 3%. $6k for 400 Gbps IB is actually NOT that bad when you think about $/Gbps (for a point-to-point connection). I use 1 GbE as the "management" port these days. Server consolidation meant that I was able to SRHINK my network (rather than to expand it). But on my systems that have the space and is able to support it, I have 100 Gbps going to my Ryzen 9 5950X HPC compute nodes and also a 100 Gbps going to my Core i7 3930K which runs my LTO-8 tape backup system. It takes the "stress" off the 1 GbE layer and moves it completely over and the 100 Gbps can handle a lot more things happening at the same time.

@ServeTheHomeVideo Жыл бұрын

Well that is also a direct connect IB versus through the switch 400GbE.

@ewenchan1239 Жыл бұрын

@@ServeTheHomeVideo Yeah. I forget what my point-to-point ETH bandwidth losses were compared to a point-to-point IB bandwidth. I don't remember if I ran my testing on the 100 Gbps IB through my switch or if it was a point-to-point test. I would think that the bandwidth losses should be lower on the point-to-point side (because you aren't going through a switch), but I can't say that definitively. Very cool. 100 Gbps IB is fun. People give you REALLY interesting looks when you tell them that's what you run in the basement of your home.

Hi Patrick, How were you able to connect the OSFP HCAs to the QSFP-DD ports on the switch for the Ethernet testing? I just re-watched the video, starting at the 12:30 mark, where you're referring to "funky optics", I'm assuming these are QSFP-DD w/ MPO on the Switch Side and OSFP w/ MPO on the HCA side? I also read the Main Site Article, where you also talk about having to navigate different signaling speeds in-between the optics. I then looked in the STH forums and read the 2 threads discussing OSFP, and posted on one of them. Any details you can share would be much appreciated.
