Since we've brought it up here's a fully configured IBM Z-Series Z14. This one has all the bells and whistles and will set you back a cool $30M plus USD to buy outright. I've only seen maybe 3 or 4 fully configured this way. Most have fewer features. I'll go through what you're looking at.Starting left frame top. 2 backup batteries. Below that are 6 bulk supplies. A redundant 6 on the backside. The system operates on 480V 3 phase. Below that where all those cables meet are the power controllers. A redundant set on the backside. And below that are 4 I/O cages, which also extend to the backside. Most customers order majority fiber I/O cards with some mix of copper. That LCD panel with keyboard is for servicing. It is normally retracted into the frame. And there is a redundant LCD panel/keyboard behind it.Starting right frame top. 2 system controllers called “System Elements” or SE's. A primary and hot backup. They are basically a PC running an IBM modified form of red-hat with a unique GUI. They are what's connected to those LCD panels. Below that is another backup battery and another I/O cage. Below that are the processor drawers. There are 4 or them in this machine, the maximum. The minimum is 1 drawer. They are water and air cooled. Below that are chillers/pumps for the water. A primary and backup. In this configuration it is a stand alone closed looped system. No “house” chilled water is needed. But a customer can order a cheaper pump system that does need chilled water for heat exchange.
Well, for your IOT toothbrush, coffee machine, toaster, ... a little internet austerity will be no problem. .. and for the media stuff you could enable access, but could still track to whom it talks to.
30M is impressive for a CPU cluster like this one. How many are sold each year ?

Due to the use of liquid cooling, the Cray-2 was given the nickname "Bubbles", and common jokes around the computer made reference to this unique system. Gags included "No Fishing" signs, cardboard depictions of the Loch Ness Monster rising out of the heat exchanger tank, plastic fish inside the exchanger, etc.[citation needed] The power consumption of the Cray-2 was 150–200 kW. Research conducted at the Lawrence Livermore National Laboratory in the early 90's indicated that to a limited extent the perfluorinated polyether used to cool Cray-2 circuits would break down to form the extremely toxic gas perfluoroisobutylene[2]. At the time Cray had created a poster showing the transparent "bubble chamber" that the cooling fluid was run through for visual effect, with a spill of the same material glistening on the floor—the joke was that if this actually occurred, the facility would have to be evacuated. The manufacturer of the liquid developed a scrubber that could be placed in line with the pump that would catalytically degrade this toxic breakdown product. Each vertical stack of logic modules sat above a stack of power modules which powered 5 volt busbars, each of which delivered about 2200 amps. The Cray-2 was powered by two motor-generators, which took in 480 V three-phase.
Looks like neo took the Red pill AND the Blue pill... Welcome to hell, buddy. There's cold Dew in the fridge right next to the leftover breakfast tacos. The everything bagels are
I suspect it’s the white beardy dude surrounded by angels in this case.
At the same time they managed to make Apple Music lag out occasionally.
On the subject of TEA I’ve been participating in an offline discussion about tek stuff for about three months with some amateur radio people. They seem to have devolved into a discussion about god having a hand in their repairs rather than their own skills

Speaking of Tek. The OS-245(P)/U has developed what appears to be a retrace issue. In the first pix the intensity is turned way up and you can clearly see the retrace plus considerable “ghosting”. In the 2nd pix with the intensity more or less at normal levels the ghosting isn't as apparent and there's just a minor hook of retrace at the start of the sweep.

ISTR it being due to the mesh.If you are worried about the retrace, then it is usually possible to tweak the Z bias a little.

Now that cray is a boat anchor Amazing I’m sitting here on a device where just the GPU can kick out 115 GFLOPS. Fits in my pocket now and lasts a good few hours on a tiny little battery.

Yes people here are unusually sane. Well done!
