I didn't catch the brand/type of 100GigE card, but I hope it's PCI-E gen 4 vs gen 3. If not, the two ports will over-sub the slot.

@@Nighterlev You didn't read my reply carefully. I wasn't talking about the system, I was talking about the Mellanox card he's using. And I've later confirmed it's only a Gen 3, meaning those 2 x 100Gig cards will over-sub the slot if he tries to LAG them together and use them. No idea why Mellanox sold that 2x100G gen 3 card.

First world problem: Linus now has enough throughput to actually wear out the SSDs on his machines in 2-3 years rather than the average 5 year lifetime of these drives.
but that is also probably a tax deductible expense to them and they likely buy in bulk with discounts from the supplier this setup is pretty unrealistic for home consumer use since chances are most average folks are probably running 4K video at home tops and not using multiple editing rigs all accessing video files near simultaneously.

“Let us know if you want to see that” yeah like anyone doesn’t want to see that
I'd like to see it, but link aggregation hashing will make it very difficult to see it with a single file transfer. You'd need to have the server listening on multiple IPs and for each TCP stream to select a different interface on each end.
I love these oldschool tech videos... This is Linus being believably excited again...
I loved the editing on this one.
"It must have expandable memory for a reason!"
Well, it could be ease of manufacturing.
Some large swiches can devide them self in routing blocks. This is usualy what the added memory is for
A switch will use RAM as a cache for MAC addresses/IP Addresses and which ports they are assigned to which massively speeds up look-ups. It's obviously also used for the firmware, and any additional features such as firewalls, address filtering, virtual LANs and so on, it's also used to speed up the data transfers across the network by bypassing the switches CPU which can be a bottleneck with such high speed networking. With all of that running you can quickly run out of RAM even with 8GB on switches as beastly as the one in the video.
You can run DHCP servers, NTP servers and even FTP servers directly off of certain switches/routers like Cisco stuff, and I would imagine the Dell switch can also do those things.
You can also run docker on the switch and run some extra services.
Well, there *is* a lot that *can* be done with that memory, the question is how much of that is actually intended by the manufacturer.
Though, okay, granted, I'm not very used to the world of enterprise hardware, I only know that the prices are insane and that's about it ._.
@@dside_ru All of that stuff is intended by the manufacturer, they charge a fortune for most of it, but access to all of those features are absolutely a requirement by enterprise and dell et al are more than happy to accommodate as long as the customer is willing to pay for it.
If you've only ever seen consumer switches and routers then all of this is alien to you, it certainly was to me at first, but in enterprise that dell switch is only the start, and the features we've mentioned are only some of what's possible, and it's all intended use cases that the manufacturer will offer support on.
RDMA: *exists*
Malware writers: "OH YEAH, HERE WE GO!"
@ When you don't understand
Edit: This is my most likes ever, tysm guys!
That's why RDMA should be local only for now... otherwise, wubba dub dub MFs
Yeah, DMA over network sounds really scary lol
Malware: "It's free real estate."
@ RDMA bypasses anti-virus as the packets go through the fpga instead of the cpu. Most antivirus only analyze what goes through the cpu. FPGAs are a blind spot in security right now.
Didn't catch the model number, but given the specs I wouldn't be surprised if there is a full x86-64 processor and ram in there to run containers on that box. Cisco has that with their 9000 series catalyst switches of similar specs.

My work places of the past have had 12,000+ cisco devices with uptimes on the matter of years less software upgrades that never went sideways. You are paying for a decade of trouble-free of packet moving and an army of people familiar with everything cisco. Dell bought their switch line by acquisition of Force 10. Force 10 had the problem they had a great product line but who skimps on DC switches that until very recently cost 10 -40 grand to populate with optics.

When The Write Speed of Your SSD Is Slower Than Your Internet.
These speeds are not indicative of internet speeds. Instead this is speeds from their storage servers to their work computers.
And I thought the 2GB/s my SSD can do was fast

This network interface is almost as fast as the data transfer speeds for system DRAM memory (latency is still probably far lower though)

The POINT to a fast network switch isn't a single machine to a single other machine file copy.
It's being able to do fast file transfers on 5 or 10 such copies AT THE SAME TIME from multiple different machines.
Unless you're plotting Chia at k35 or some such with a multi-GPU plotter, then it becomes transfers from one machine to multiple other machines.
If you went for the Dell S5248F-ON you can use the Double Density ports which allows you to even go up to 200GBe , if you have the right cables for it and NICs as well :)
