The consistency you have between the German and English versions of your content is impressive enough, but the fact you managed to get the cat to do almost exactly the same thing on both takes is genuinely next level 😂
@J M Infected cats only shed it once for a few weeks. And they're are inactive until 24 hours after excretion in poop. If the litter is cleaned before that, there is zero risk. Besides, you can get it from meat, fish, goat milk, and lots of other things. It is completely harmless for healthy adults (unless you're immuno-compromised, ex: HIV). And since you're already living with a cat, it isn't a problem for pregnant women either, as they need to be infected for the first time while pregnant for anything problematic. TL:DR; Overblown.
@J M You're not going to get toxoplasmosis from a cat unless you eat it's poop. You're far more likely to get toxoplasmosis from not washing vegetables and not cooking meat properly.
I started my computing career on System/38, the AS/400, i Series, System i etc. The hardware is way ahead of PCs. One morning we got to work and saw an IBM engineer waiting. He said iSeries had a cache failure, so it organised an engineer for itself. Cache was pulled out while it was running. The system said thank you on the console and configured itself for full speed. You get what you pay for :) Awesome.
my old Boss used to sit with the IBM engineer when they where getting data errors on the storage of the system/38 and make bets on exactly when it would fail, although that came during a time well before i worked there (i would have been in preschool at that time), when i started in the early 2000s they had the as/400 - iSeries which had been running for probably 7-8 years at the time, that thing was interesting to me and still to this day i hope to find a used one to add to my homelab/collection but the prices never go down. although the biggest thing i remember from back then was waiting 3hrs after work because i accidently knocked out power and had to wait for it to boot and display a login console on one of the 3180? terminals before i could go home (connected a large laser printer to a stupid unlabeled outlet on an extension cord that ended up being connected to the UPS the AS/400 and Novel 3.12 server where on, UPS did not like it and killed itself)
And then you've also got just how long IBM will actually extend support for their proprietary stuff like their POWER line of products. It's quite crazy that they support 4 generations of product at a time, both software and hardware.
The old IBM PCs from the 80s had enormous add-in boards for memory. If I'm not mistaken, they used ISA expansion slot, which is the grandfather of PCI, and later AGP and PCIe. The memory add-in boards where taller and longer than AIB 3080s/3090s. But to be fair, these memory add-in boards are not directly comparable to DDR DIMMs. But it's fun to see how small everything have gotten.
I was going to type the same thing. The ISA boards from the 80's were full length and were bracketed. Every time I see one of those sagging video card videos. I remember when those brackets became obsolete, somewhere around the time of 486 computers.
thanks for pointing out how mad IBM was back in the 2000s, i had a powermac quad G4 that i upgraded to 16GB, which made me a freak to my fellows then. lol
Love 'em. IBM computers are stupidly tough and reliable, that most early PowerPC servers and mainframes can still be found today in excellent operational condition, no errors (although I would still recommend recapping the whole thing with new capacitors so you won't run into problem if they are over 10 - 15 years old - chips themselves are way overspecced for a very good reason so it would still work like new with replaced capacitors).
It is not the biggest. You should check other IBM D-DIMM modules for POWER10, that utilize IBM OMI interface. It is an evolution of Centaur / C-DIMM, to be more flexible, cheaper, faster (about 5ns, instead of about 10ns for Centaur) and higher capacity. They are enormous. Serial interface, with Microchip controller and mix of RAM (DDR4, DDR5, GDDR6 and HBM2) and Flash.
Every video i watch ends up with me saying to myself "and I thought I knew much" well I never even knew about this type of hardware, nor have i ever seen memory modules of such massive proportions. Thanks again for the interesting content looking forward to more.
The Dell R910 server used 8 risers for memory, each able to hold 8 standard DIMMs. I remember my first encounter with one. I was amazed how much memory it could hold. Also, I worked on some old IBM p series machines running AIX, and they had these weird DIMMs (DDR2, iirc) that were almost twice as long as standard DIMMs, and some came with dual rows of ICs.
I always smile whenever I see Roman's Stargate address tattoo. :-D Here's hoping Amazon does some fans service with the license once they acquire MGM shortly...
In the DDR1 era there were a lot of consumer motherboards that unofficially supported registered memory. The early 64-bit AMD chips are the best though, I have a socket 989 that will run 4x4gb dimms.
Absolutely fascinating video! Whenever I look at the server market I'm absolutely amazed by just how innovative and advanced the tech can get, it feels as if its years ahead of our normal consumer space.
IBM's Centaur chips were not exclusively found on massive proprietary DIMMs. The low end POWER7/8 systems had them installed on the motherboard themselves and had ordinary DIMM slots linked to each Centaur chip. It was a typical dual channel arrangement supporting up to two DIMMs per channel. That is likely why the IBM custom modules are so large as they're effective four DIMMs in one. Another note is that these DIMMs support ECC and IBM's ChipKill technologies so one DRAM chip can completely fail, be disabled by the Centaur chip and then continue operating while ECC is still maintained. I *think* those custom Centaur DIMMs could also be hot added to a fully running system. The L4 cache of the Centaur DIMM does indeed function as a cache but its contents are restricted to the information of the DIMM itself. While it does improve performance, it mainly offsets the impact of using buffered memory. Adding more DIMMs does increase performance of these POWER7/8 systems even if memory capacity is kept at a constant. IBM did release both DDR3 and DDR4 version of these DIMMs and they are interoperable. However, there two different Centaur designs to deal with the different memory types. POWER10 changes things significantly by using a common interface for multisocket communication and their memory buffers. Eight links are always dedicated to memory while an additional 8 can be used for SMP traffic or even more memory. It is pretty flexible so a single socket only system can have 16 TB of memory with a bandwidth of 2 TB/s which is very impressive. The big iron servers are only leveraging 1 TB/s of memory bandwidth and top out at 8 TB of memory per socket and upto 16 sockets in a single node. Memory sharing between nodes is also possible with the POWER10 but cache coherency is lost. 3D Xpoint memory or as it is more commonly known as from Intel as Optane, is a very interesting technology. Being byte addressable does permit it function as main memory. Intel initially was going to have Sky Lake-SP support these DIMMs but due to bugs had to disable that functionality. Similarly Intel was planning on permitting full Optane memory on its systems before requiring some DRAM to be installed. While the performance of Optane is slower than DRAM, it does permit some interesting potentials in software optimization: the full removal of the traditional storage stack as everything then becomes 'in-memory'. With enough capacity, those Optane DIMMs would double as both main memory and traditional SSD storage. This reduces operations like say loading a game into memory to zero because when you are not running that game, it is is already sitting in the Optane DIMM. Like a RAM disk but without the need for the traditional storage software layer to function.
I remember back in the '80's and '90's, RAM extender boards, where you stacked like 4 or 8 SIMM or SIPP modules, and plugged that into one socket on the main board.
Seeing custom tech is always fun. Makes you realize how profitable the server market is when they're going out of their way to engineer such things in order to keep with their clients' demands
I'm enjoying the technical breakdown of the POWER architecture you've been doing since that server showed up. I don't see much about POWER in my usual tech circles, so thank you. 👍️
I work on mainframes, we still have System p (880), plus I also have some S814 servers, nothing more modern than POWER8 though. For me (I'm all about OLTP databases), anything after POWER5 was useless. I don't need SMT8 and huge caches, I need real IOPS instead :/ (x86-64 with NVMe is way better than pretending you have awesome ROI by running lots of databases on LPAR-s though VIOS, and it's cheaper, too :/) But I'm fairly confident the SPARC boxes we've decommissioned few years ago had bigger memory modules than your biggest ones. Sun was so awesome before Oracle takeover, RIP Sun :( I wonder whatever happened to jpkiwigeek :(

I work in a government IT department (in the USA) and was sorting some really old surplus equipment a little while ago. I ran across some really weird DDR sticks that were double the height that had some other chips on board other than the DRAM. No idea what they were and unfortunately they were sent to the recycler. I'm curious as to what those were now...
Get it, Shiek! LOL You know, when I was a child, my teacher never believed me that my cat ate my homework. I wish I had TH-cam back then. Shiek would have backed me up. LOL My childhood cat would literally place his paws on a piece of paper and then rip it up with his teeth. Usually to wake me up when I did not feed him early enough. To memory though! We are always hearing about how non-volatile RAM will change everything about computers. Still waiting... LOL Nothing changed for the PC. Servers ... some niche uses. But nothing huge either. What happened? And maybe just as important: what do you do when resetting the power doesn't reset the memory state and clear persistent errors?
There is so much more different types of technology that normal PCMR doesn't know about because it never made it to mainstream computers. It's very cool to see.
Pmem is just like an m.2 ssd (though closer to intel optane ssds performance wise) but in dram format instead of pcie. It is useful for computers which need very large amount of storage and don't have pcie lanes available (for example iscsi/nas, database cache, geographical data...)

With desktop RAM you often have a single row of ICs. in the server world, they're often stacked on top of each other for 20 IC on each side. Somewhat like laptop RAM, often times this is for fully registed dimms, but it could be for capacity
Cisco calls it NVRAM within IOS, but it usually is EEPROM or flash memory. For some reason Cisco often takes industry standard terms and re-uses them. Storing device configuration should typically only be done during re-configuration, for which flash with write speeds well into the MB/s is more than fast enough. EEPROM which has write speeds of anywhere from 100KB/s to a few MB/s is also more than fast enough for configuration data. There would be no need for NVRAM for configuration storage. In fact, in some documentation Cisco refers to the configuration file stored on flash memory as being named 'NVRAM', kind of like taking a file on your pc, renaming it 'NVRAM.jpg' and claiming that is now actual hardware NVRAM. Part of the reason I don't like Cisco; you always have to dive into the documentation to figure out what their marketing team meant when they overruled their engineers again.
I have some ram sticks with 4 coin nimh cells which works as "nvram" (basically just keeps the ram powered on till the pc re boots), they were in a raid card.
Don't know if that's biggest by IC amount, but it sure isn't the largest by physical size. I suggest looking at vintage 1980's ISA ram board. There's some with 130 slots for memory chips that you had to install yourself into the card that probably wouldn't fit a modern computer case. They could add whole megabytes of memory to your computer!

An interesting little fact: Cisco gear often has some nvram in them. It's used to store the active configuration.
Cisco calls it NVRAM within IOS, but it usually is EEPROM or flash memory. For some reason Cisco often takes industry standard terms and re-uses them.
Storing device configuration should typically only be done during re-configuration, for which flash with write speeds well into the MB/s is more than fast enough. EEPROM which has write speeds of anywhere from 100KB/s to a few MB/s is also more than fast enough for configuration data.
There would be no need for NVRAM for configuration storage. In fact, in some documentation Cisco refers to the configuration file stored on flash memory as being named 'NVRAM', kind of like taking a file on your pc, renaming it 'NVRAM.jpg' and claiming that is now actual hardware NVRAM.

I have some ram sticks with 4 coin nimh cells which works as "nvram" (basically just keeps the ram powered on till the pc re boots), they were in a raid card.
Chrome: Finally, a worthy opponent!
LOL
Power9's are neat machines. I work on them alot and have 2 of them in my lab.
" But there are even weirder sticks a lot wider "...... Do go on, I'm interested
A:Why do you have a 1600W psu?
B:My RAM takes 400W
😆
Who cares about hardware when you can watch a cat being playful and cute.
I came for the interesting hardware stuff, I STAY for the cat :)
Don't know if that's biggest by IC amount, but it sure isn't the largest by physical size. I suggest looking at vintage 1980's ISA ram board. There's some with 130 slots for memory chips that you had to install yourself into the card that probably wouldn't fit a modern computer case. They could add whole megabytes of memory to your computer!
will you be able to review the Power9 OpenPower motherboard by Raptor Computing as well?
Thanks for sharing, like it :)
will you have a future video on using CDIMMs on Consumer Desktop Motherboards?
thank you very much for making such an interesting video, i am very curious to know how much u spent to make this video.
G'day Roman & Shiek,
You started the video too early, Shiek hadn't finished Proof Reading the Data Reference Sheets 😸🥰
Ps WooHoo! Another Server Road Trip 😁
Okay, that does it.
Been considering it for a while, but the 1st minute or so in this video made me decide that Im getting a cat.
Well, where could I purchase one of them?
Could we use PPM sticks to have OS on them?
“DUDE What if we made the whole thing D RAM?”
“DUDE!”
could you take a look at more of the ibm power cpu's i remeber seeing the power 7 when it released thinking wow a 8 core cpu with 32 threads!?!
Yep haha, SMT4 is so awesome on the Power architecture
Garfield lost some weight! 😂
I can only imagine how zealously Shiek guards NDAs 😂
Again a good lesson
Chrome: PLEASE PLEASE PLEASE!!!!! BUY ME THOSE RAM SITCKSSS!!!!!!
Me: In your dreams... I'm too broke.
