When did you first start seeing data centers move to 415/480V? Had a customer just finish building a 208V DC and now we are telling them new requirements for liquid cooled GPU compute requires 415/480.

---

I forgot to ask, what size is their data center? The water to chip is only a few years old in major data centers. "We" do 200 MW. Amazon is doing an 800+ acre site in Jackson, Mississippi. Didn't want to live in Jackson.

I believe it's about 60 racks, not very big. I don't know how the customer made the decision to go 208 but it sure seems a uniformed decision especially considering their need for gpu servers and liquid cooling being required going forward. They also only have 240 amps to each rack.
Dells liquid cooled gpu clusters require 415/480, it's the only way to get density per rack. Now we have to see if we can build a custom solution.

Certainly does seem uninformed since it's all about ball bearings nowadays.

Yup I think it showed up my sophomore or jr year 04/05 timeframe if I recall correctly

Yes, I know but it started to catch on in 2007 or just prior. At least that was when I got on it.

I even remember how it happened, I was in the library studying for an exam and corresponding with an Aggie former classmate and we were discussing our kids and he said send me some pics. I asked if I should email them. He said no, put them on Facebook. I asked WTF was "Facebook". Then he told me but I didn't want to sign up to another website but eventually I did a couple of days later.

You are remembering when Facebook opened itself up to everyone. Facebook required a .edu email address for you to register back when I started at A&M, in 2005. In 2006ish, they opened up to high schoolers. Around 2007, they opened up for everyone.

The moment they did that, it was pretty much dead, imo. Before that, it was an amazing place for college students to organize, share photos, and be our main social media access. When they added high schoolers, it was still cool because you got to include some of underclassmen you used to go to high school with.

I still remember the day they announced anyone would be able to start using Facebook. I call it the great cleanse. So many students panicked and started deleting all their party photos and such.

You are right.
I only learned about what you say by reading about it much later. Was not aware of FB when it was. edu only. Still, it was very good for a few years after that. Last few years I don't see any posts from my friends but lots of ads. At least I get to read the groups I am interested in.

heh... interesting... I wonder why I missed hearing about it. I was in grad school (post A&M) so maybe I wasn't reading much outside news

IG is just weird now. I might see one post from a friend per day. Other than that, it's AI, sponsored crap, and memes. The memes are funny and about the only thing that gets me on there when I just want a chuckle. Other than that, it's a 100% useless app.

---

My Insta feed is all women with great racks cooking a recipe. Their algorithm is pretty good at determining a person's interests.

---

And "fitness" instructors.

But at least the bait and switch to porn sites doesn't show up on my feeds anymore..about 5 algorithm resets later.

Also, its kinda sad, I don't think you can get views for a recipe if you don't have a good rack.

And after all the billions, spent worst search on the internet.

Is there ever good new regarding AI? Every single thing you see, hear, read about AI is always bad. People losing their jobs, data centers expanding everywhere, more and more investment in AI.
We're ****ed.

I have to wonder if their offices are anywhere near as extravagantly lazy and non-productive as we saw when Elon got into Twitter

---

You just know it's at least similar. That's the whole vibe of Gen Z. They want 6 figure jobs where they actually work for 15 minutes a day and spend the rest on social media, posting bull****, and having lattes.

My general experience is that it's not hard to find hard-working young people. If you establish a reputation for very high wages, you draw a solid candidate pool that lets you select kids who demonstrate clear motivation. If you establish a reputation for second-class pay, you get a second-class candidate pool that forces you to select the cream of the crap.

Amazon expects to dbl production level while keeping head count level. This is what the future looks like, keeping investors and WS happy.

I guess you haven't been around lately. Those jobs are so beneath the people getting laid off. They deserve better and shouldn't have to lower themselves.

If their salaries are $200k each it's still a drop in the bucket compared to their investment in AI. AI is the bubble that will burst soon enough.

---

Yes it will. AI is insane and is going to be very useful. It will change the world an order of magnitude more than the internet did which doesn't seem possible, but it is.

But all of this investment right now is just Monopoly money being used to prop up the stock market that everyone knows is a Ponzi scheme.

Treat it as an opportunity instead of a structural job killer. There will still be jobs available. There is money to be made here. Look for investment opportunities. We have one poster in here doing just that, even came out of retirement. This will require change, which is difficult I know (been there, done that).

I don't mean this to come off in a mean way but it's seriously boomer clickbait to badmouth AI. It's just a more accessible version of machine learning algorithms many industries have been using, for years in some cases. I love being able to develop simple tools or code... I barely know any code. I don't even know how to develop code and can keep asking questions until I get a reasonable solution

I am 62. I start on Monday to build hyperscale AI data centers. My retirement lasted a few months. They can't get Gen Z to work. I got so many calls.

---

Is your company publicly traded?

---

No. The company I worked for building data centers in Europe does not even have a website. No signs on the buildings we built.

While on the subject, we are doing water cooling direct to the chip. Closed loop. So if anyone says data centers use so much water. No. We have fixed that.

---

I mean it's all relative. What do you do with the heat you rejected from the chip? Gotta cool the building somehow. You can do it without water sure. But you can reject more heat cheaper by using a water source. It's just a cost and benefits thing.

---

We use water in two loops. One loop is treated water that goes through the racks, that are now 50kw or more. Then this goes through a heat exchanger to a water loop that goes through an air-cooled chiller. No evaporative cooling towers. A 50 story high rise uses about 50 gpm or more for make up water for cooling towers. The new data centers are not designing evaporative cooling.

---

That is the scheme that I have envisioned, and pushed back several times on people saying "data centers need to use so much water".

Does that scheme work everywhere, or do some areas have too high ambient air temperatures to be feasible, without adding refrigeration?
