AMD Pensando - Wire speed 100gbe with no CPU overhead is here today 

Yeah exactly. And you can migrate the job between nic and Aruba switch (!) Pretty seamlessly tho I haven't tried that they are already doing that at scale

Are the latencies comparable though?

@@rkan2 avoiding handover to the CPU, to ASIC or like video contains - there's tons of performance boosts to be had - cpu's sucks speedwise on handling network traffic, not even including additional packet analysis..

@@ewookiis 2-3 times copying over before it gets received or sent out does not help, that is where a lot of the beneft is. Way back I ran a weird ass userspace network stack already for 1Gbit, near 0 cpu overhead and I squeezed out a few more Megabits consistently. Then I bought 2 cheap Infiniband adapters from eBay, kinda slow, unimpressive. Then I put one in my nas 1 in my pc and paid attention, set it up properly. WOW so fast, and cpu use went way down. For 100Gbit? I can only imagine.

@@jamegumb7298 agreed. I’m really excited!

AMD goes faster and faster for a set price Intel gouging your eyes out for every little bit of there performance why cause they are intel🤣🤣🤣

I have 2 bit ECC on my NAS thanks to AMD and Asrock (cheapo pro apu). Intelololol

@@TheGuruStud Which board and apu model specifically?

@@RN1441 I suppose any of the x470 / x570 asrockrack boards and any 5xxxG APU?

@@RN1441 x470 taichi and 2200G pro. Obviously, there's a lot better options, now.

When the software devs and hardware devs don't like each other

Boooooo, booooo! 😂

I have a feeling that this is not a channel for topics you've mentioned

@@malborboss There are far more specialized channel on these topics. That said, none covers a wide range of topics (but focusing on infra) with hands-on devices like lv1, so I think they can make a great video on this.

I have no idea what he's talking about but I'm here anyway. I like Wendel.

Zi (that's short z, not zed z, or zee z) (sounds like sigh) links. Why? What are other people pronouncing it as? Exxey linnex?

Of course, it is the next step in computing. And the one with the more cohesive platform will win. Right now, it kinda sounds like that's AMD.

oh he is visibly out of focus, oof. Look at that sharp brick wall, though!

@@snaky115 Oops. You're absolutely right. Brick walls for the win.

he knows we all want to look longingly at the bricks in his wall

you gotta love how windows pegs a single thread to bottle neck the download🤣

What are you saying 😂😂😂😂

Agree

The computer is the network, duh.

Aruba has a very weird price policy. 80% discount even for medium sized customers are not unheard of

Switch? This is a router? A firewall? A lot more than a switch.

Varnish lets you do much more elaborate caching policies and request processing. Its VCL is a full blown programming language and let you do pretty much anything from custom hashing, cache eviction, request/response modification, merging two backend fetches into a single response, cache bypass depending on request content etc… If you need to configure your caching more granularly then varnish is the way to go. Unfortunately the learning curve is pretty steep, documentation is suboptimal and there are a lot of public VCL examples which are either wrong or outright dangerous to deploy. Nevertheless it is a powerful tool after you get the gist of it.

Their customers don't seem to be irked with all of their security screw ups on repeat, so doubt this will change their sales.

Pensando's should be able to do those ZFS tasks, look at Wendell's video from the Bluefield DPU. It also means there would be DMA from the disks to the network if using a network share on top of ZFS. I'm now wondering if these would be good to offload Ceph 🤤

This is not for soy devs or peasants, it's for serious people working at a large scale. No one is going to hire JS 'devs' to write DPDK code.

Agree he looks a little out of focus on my 42" 4K monitor. I find it off putting. Enjoy his presentations though he always makes and provides cogent examples.

that's a lot of conspirasy theory, will you lay your own fiber, routers and switches between locations you want to connect?

@@wiziek No, as I mentioned already, I will use whatever is available and presume it unsafe and do my best to provision for it. I will not write the software to rely on magical black box security, like say SSL. Of course, I also use SSL, but also not rely on it as a magic catch-all solution I can safely do insecure programming under. My code will in fact be just as safe if it didn't use SSL at all, I am only using it because browsers complain about it, and some outright refuse non-SSL connections. There's zero reliance on SSL for security on my end. It is no different than relying on your software users to maintain safe systems. You can't possibly know what a user does with a system, in addition to run your software, what sites they visit or what software they install, and how much malware they might have running. I do not presume that my software will run on a safe system, whether that's an end user system or a cloud instance.

@@wiziek How is saying you won't implicitly trust something you can't actually know the inner workings of conspiratorial? From Intel ME to Cisco back doors, the list of untrustworthy devices doing things that are bad and that the user can have zero vision of are pretty numerous. I would be far more curious as to why anyone WOULD trust at this point.

just saying, if there's a chip that is allowing a backdoor, no amount of software can stop that. look at the people with full rooted pixel phones that still ended up with the cough tracker getting loaded on their phone. if it makes you feel better that's fine, but know that software loses to hardware.

True sir, but software engineers are a lethargic lot, they will still push computations thru the CPU even if they are given a specialized accelerators.

The one shown in the video (Alveo U30) is based on the Xilinx Zynq platform, which is in fact a SoC with a Programmable Logic (PL == "FPGA") integrated among a quad core ARM Processor block, Memory, DSPS and some high Speed I/O of various kind. These Devices are not pure FPGAs like some bigger / older devices. There seem to be pure FPGA based solutions in the Alveo lineup though. Also the newest generation of Devices from Xilinx is the Versal Line which they call ACAP (Adaptive Compute Acceleration Platform ) which is basically a Zynq in much bigger with AI accelerator engines in there too (think High Pref. ARM Cores + large FPGA Block + AI Accelerators + All the I/O and Memory stuff in one Device)

​@@memory_stickall true, however they have ASICs inside to do the video encode/decode. You'll see it referenced as Xilinx IP, which are the something-on-hardware blocks.

I do, but I already use Docker, Nginx, etc (not Drupal, tho), already know about what Pensando (and XLNX) does, BlueField, smart-switches and all that. It's an incredibly interesting topic, and it's the near future of general purpose computing for datacenters.

I think Windows is acting as a bottleneck for you there. I've found it's much more difficult to saturate a 10Gbps link in Windows (jumbo frames and all) than in Linux. I never bothered to nail down exactly why. I don't think it's your storage. Even consumer SATA SSD's will easily saturate the link at rated speed.

@@TrueThanny I would love to get faster throughput but 430 MB/s is pretty good. I watched a Linus video where the dude was getting like a gigabyte per second and I was like, "No way..." I know the SATA controller is throttling down after it heats up and so I've got some stick-on copper heat sinks on order. I'll try to see if I can do a little ad hoc passive cooling to take some of the pressure off. But, I watch the Performance Monitor and as these files are copying, the RAM in the sending computer fills up until there's like 3GB free then the copy speed plummets. As long as the file is under like 30GB, I can get away without the speed tanking like that. I have a couple 40GB+ VHDs that copy fine for awhile but then, once the buffer maxes out, BOOM, the speed is cut to less than half. Also, smaller files take longer in this scenario. I have a folder that contains a lot of support files and when the copy routine gets to those, the speed drops to the floor. It's copying a lot of files but there is so much File Open / File Close going on that it takes extra time. I mean, it's not terrible but it's a big difference. Overall, I'm pretty satisfied. The move from HDDs to SSDs was (obviously) tremendous. Also, that Mellanox 10Gb NIC is the tits. Certainly, I'd love to see the Linus 1GB/s performance but I'm not working with enterprise level hardware in any of this. I guess the Mellanox cards are enterprise but that's about it.

...and damn, I thought I hung on to PHP way longer than I should have 😂
