Intro and Outro Music: "Earth Bound" by Slynk
Other Music: "Lively" & "FollowHer" Zeeky Beats
If Allyn is from Intel, they need to send him more often! He was a very refreshing as a PR person that actually seems excited about the tech.
The glory days were when Allen would do deep dive reviews of drivers for PCPer
@@dylansmith9215 "deep dive," in this case, being insufficient to describe how obsessively detailed those pieces were.
Yeah, Allyn isn't a PR guy, but for Wendell he'll turn up with gear and geek out. This guy knows his stuff more than almost anyone else on the planet when it comes to storage.
i'm interested in allyn's official intel title.
bug tester?
@@acasccseea4434 Storage Technical Analyst.
I'll take two. Seems tasty.
this man cannot be stopped. DO NOT EAT THE SILICON.
Allyn is as well spoken as a great PR rep, talking about stuff with the depth of knowledge of a senior engineer at Intel. Serious props, this was great to watch.
Omg it's Allyn! I always loved his in depth knowledge about storage and memory and I remember this one story he told about being in a submarine and having to fix something before they got caught being somewhere they weren't supposed to be.
14:23 - In APL and J, we use memory-mapped I/O a lot. That lets us write clean, elegant algorithms that that have NO I/O, so we get superb performance and the mathematics is not hidden behind all that memory clutter. Several days of your basic database work turn into ten minutes of simple code that you can explain to your colleague when playing You Bet Your Company.
This is mad science of insanity. "I'm just gonna yeet 100GB in a second and see what happens. Oops the computer got scared acted weird."
I always love these nerd chats, even if they talk about stuff that is completely out of my reach.
I'm gonna be straight with you Wendell. This may be the next level content on this channel. I'm getting some serious "Jay Leno's garage" vibes from this video. 1 You bring in an interesting computer
2 have a passionate conversation about it and get into the details
3 You say "Can we take it for a spin" and do something fun with it.
Nice to see you Allyn, excellent stuff as always.
"Not worried to be losing data". Even with "persistent storage" we're doing RAID etc to provide redundancy. Are we going to do PRAM RAID now? :D
Would be interesting if the CPU had non volatile cache or a mirror of it so if you pull out the power cable and plug it back in it continues right where it left off in a millisecond.
it's impossible to have a perfect 1:1 non volatile cache, at least with current technology. L1 cache access is in the 1ns range, and registers are sub-nanosecond... they would've been written to a thousand times over before you could sync to optane pmem.
Back in the day when Allyn was still at PCPer and reviewed the first optane products, he helped me pick optane disks as swap for plain old kvm hypervisors. It basically made our memory pool for virtualization about 3x in usable size with overcommitment in runtime state. Imagine the savings comparing optane SSDs to the same capacity of RAM...
please invite him more often!
I really liked this episode. Allyn was def a treat to watch as he appears to be genuine in his love for tech nerd deep dives.
Always great to hear from Allyn. Thanks for bringing him on for a few videos.
Finally! That is what I've been expecting to happen since optane was first announced! It's very exciting!
Just awesome! ^^ Thanks Wendell and Allyn!
Another awesome storage chat. Eager for the next.
Tomorrow :)
The conversation about NUMA and cache migration/copying reminded me of the Extreme Black Magic involved in the SGI Altix systems I used to admin. Maintaining cache coherency across multiple rack cabinets is terrifying and amazing when you dive deep enough down the rabbit hole.
Allyn always comes baring gifts :) Great stream.
that was HELLA INSIGHTFUL!!! I have never given much thought to computing on this level, and it really is bonkers!!! THANK YOU FOR THIS!!!
We need more Allyn!
Great Stream, love Allyn..
That was brilliant. Thank you.
Thanks Wendel, this is the good stuff!
i understand like 1% of the topic, but i do enjoy the conversation. keep em coming
I saw Allyn in the thumbnail and had to click, for the PCPer nostalgia sound of his voice
fun chat indeed. love a good nerdfest. hail to the king, baby.
STILL waitung on that "sound test" we were promised
And I was excited about a new 1t gen 4 m.2
Maybe a stupid question regarding client SSDs with DRAM but no powerloss protection: If you power the SSDs not just with the computer‘s PSU but use small powerbanks for 5V and 12 V, would this add functioning powerloss protection?
Pmem isn't a free lunch. CPU's have several levels of caches and write buffers that have the same basic role and semantics. Yes. When you write to pmem it doesn't actually get to the media unless you use the special flush instructions. So you end up doing the exact same crazy stuff done for filesystems for you pmem where you write unsynced and then flush at critical checkpoints.
In that respect it's the same as even the client SSDs.
Father Wendell. In the thumbnail I thought Wendell was wearing a priest collar.
And woo hoo, Columbus is getting an Intel fab!
Yeah, if someone breaks in, rips all of them cables and Optane P5800Xs out but leaves the Xeon platform completely alone I wouldn‘t know at all who might have done it…🙃
Wendell, Allyn, Storage, I'm in!
I wanted to hear the full power of deathstar on the table, you should have spun it up.
Wendell going towards server rack...
...servers sweating profusely.
CES? What CES? This was just 🤗
Awesome server and talk!
RIP Optane: 2017 - 2022
I don't quite get the interest in the Samsung MZ-1LV9600 ... kinda old news (on a 2022 video) ..?
But these guys know this subject better than I (by far) so I assume I'm who's missing something... but what..?
What a wholesome video
@3:00 Only Oracle? HANA!
I see Allyn, I know its going to be insane and cost a ton! Lol great video!
Wow a whole 88 lanes? And you only need two processors? *laughs in Epyc*
Level1 mini-CES, I'll take that
and you'll take my _engagement_
Around 2 years ago Linus dropped a 10k CPU. Today I have a system with two Intel Xeon platinum p-8124 cpu's. In four year if I'm not playing minecraft Java edition in Linux mint on equivalent to this system I'll be very disappointed in myself.
I want this in my homelab!!!!!!
I think Allyn can single-handedly go against all of the bad press Intel has gotten over the last decade
Excuse me, can I shout out to the Editor, for handy little on screen definitions of the causal jargon terms please? Thank you
Great video guys :)
Still a pcper fan,
It's a half drunk ramble about tech every week over there
I'm checking them out again now. Didn't like Jim at all, but he seems to have left, so maybe I can binge and re-sub :-D
Remind me of the riovista from long ago
Yes, bring Wendell the CES
YAY!!
Lovely people with lovely hardware.
Holy schnikeys that's a pricey server. Enterprise hardware costs always blow my mind. You could have so many Chrome tabs with all that RAM.
finaly proper Anime storage
Can you use these second-gen Optane DIMMs on AMD platforms? 🙃
Love it!
Does this break the Von Neumann architecture requiring different compilers as storage is really memory and data? Couldn't your data and instruction memory be the same thing? Just curious likely I am not understanding it.
Lots of changes need to happen to get to what you’re describing. We might be there today if PMEM tech came about say 20 years ago.
Core baby
Come on.. Turn it on and show some benchmarks and real life performance 🥺🥺
so.. I should continue using my 16 core X299 system then. :)
They are 3 bin´s higher, ie 300 mhz. I´m like what you count 100 hz as one bin lol.
Is allyn gonna put this into his Tesla?
Technically it was (I had to get it there somehow :) )
@@malventano Why didn't you "travel by telecom rack"? Is PMem too delicate or were you afraid of ending up in LMG Studios?
Referencing this BTW (When Wendell helped Gamers Nexus build a new NAS): czcams.com/video/Hix0l8cFaMw/video.html (this is the punchline of a 2min joke)
250K you say? I'll have three.
I looked I couldn't find any, can some one smarter then me make a sata power loss protection adapter for drives without the caps internally?
Server? Dont even know what i would use one for. Do i need it? YES :D
I like when you have allyn on :)
Its feels almost like being visited by someone from the future lol
Why do you need this kind of a server? It is useless for OLAP because 4TB is almost nothing in terms of disk space. It might be a valid platform choice for a search engine, in-memory queue or an OLTP workload, but why do you need these servers unless they are not so expensive? It feels like you still need checksums because even ECC memory fails when you have 100k machines.
That's a lot of cake
Memhive seems like a good day 1 use of pmem
Fuck, that shit neat dude.
So, i want to download the interweebs. This is the tool i need? And yes, i'm dumb.
Allyn is worth Gold Good sir.
Who are you calling a retimer?
i wanted to hear the fans scream
Luckily LTT is not there to drop it. :)
*claps*
woop
This is like a Netflix edge server.
But wait -- really .. ? In "10 years this won't be a couple grand on eBay" ..?
I'm skeptical of that. Highly in fact. I think tha'ts exactly what it'll be by then. (at most)
pleb tier developer here: so I basically I don´t need Redis with p mem?
Can this thing run a minecraft server?
Sadly, I think it's time to pull the plug on this channel. Between the recent video discussing the pope and pets to this one talking about hardware fantasies at a time when I cannot get mainstream memory, I don't see the relevance of the channel anymore. I'm not even sure who this channel is for anymore and I've been in IT since the 70s. Best of luck in the future.
Wendel do you work at Intel too? You always joke that you're janitorial but you are knowledgeable, I wonder what you do professionally.
