For later generations of Chinese, when it comes to the Dahua project, the most impressive thing is PX, that is, paraxylene, in English, pxylene, an aromatic compound.

It is famously due to the prevalence of anti-intellectualism in the new century, and the mixed chemical reaction of despair at the bottom of the TG.

Theoretically, PX projects can be considered harmless, as all highly carcinogenic and highly polluting intermediates are treated before they are released into the atmosphere. Theoretically, however, there should not have been fires and chemical explosions at the port of Dagu. The problem is clear to everyone, not only the credibility problem, but a lot of low-level chaos is clearly placed there.

Hu Wenhai shook his head and took back his thoughts of running away. The difference between PX and PI projects is one letter, but in fact, everything is similar, and they both belong to aromatic polymers.

On the other hand, however, the difference between the two is as great as the difference between iron and titanium. The low cost of PX makes it suitable for a wide range of applications, but its performance can only be described as mediocre.

And PI, that is, polyimide, can be said to be simply the aristocracy of aromatic hydrocarbon polymer compounds. It can do what PX can do, and it can still do what PX can't.

Of course, normally no one would use PI to do PX things, because the cost of PI is too high.

In the field of thin films, PI has a nickname, which is called "golden film". Not only to describe its wide range of applications and excellent performance, but also to describe its high price.

Polyimide is the highest grade of insulating material due to its high temperature resistance of 400 degrees Celsius, long-term operation between minus 200 degrees Celsius and 30 degrees Celsius, no obvious melting point and ultra-high insulation. Its uses are all over the aerospace, microelectronics, nano, liquid crystal, laser, molecular penetration and other fields. If Hu Wenhai were to fully introduce its performance, I am afraid that he would not be able to finish it in 6,000 words.

Generally speaking, if someone asks him whether this thing is important? Of course it is important! BYD's high-end lithium battery will have to rely on imports in the future! Even in the 21st century, when China's Dahua projects are blooming everywhere. PI's annual output is only a measly 1,500 tons per year. Yes, Hu Wenhai definitely didn't remember the decimal point, this thing is only more than 1,000 tons of production in the country.

Needless to say, PI film is the key technology to solve the lithium-ion polymer rechargeable battery. Of course, lithium-ion polymer batteries can be produced without PI, but they are not very good in terms of performance.

What's more, this thing is not only needed for lithium batteries. A large number of high-end military, industrial, aerospace......

In short, there are a lot of "imperial toys" in Hu Wenhai's imagination, and it really can't be done without it.

In short, in short, this is a kind of "awesome" to explode material.

And if a technology like this kind of "" explodes wants to be exported and spread, it always means a lot of trouble.

Hunter Dupont thought about it carefully, but fortunately, he was indeed not the second ancestor of straw bales, but a very capable successor. Soon, he got PI's information out of his head.

DuPont is one of the inventors of polyimide materials, and has been researching this material as early as the 60s of the United States. By the 80s, DuPont was already the world's leading producer of PI materials.

Hu Wenhai's request. It's like digging up the roots of DuPont.

But then again, no matter how good the PI is, the output is there after all. The price of this thing is high, but the production cost and output are also very problematic.

That is, its total market volume is limited.

The third generation of lithium water battery, in theory, this thing can even pose a threat to petroleum power.

This is too powerful, the theoretical application market of water lithium battery is far more than the PI market. Profit for DuPont. Not an order of magnitude player.

You must know that in China, enterprises belong to the state. And in the United States. The state belongs to the consortium.

It is really not too easy for a 200-year-old brand like DuPont, which is almost the same as the United States, to manipulate Congress to export a technology to China in the honeymoon period.

Again, in the honeymoon strategic period between China and the United States, it is not the Americans who block and do not sell. But even if you are willing to sell China, you can only feel the small money in your pocket, squatting in the corner of the wall and drawing circles.

It's too TM poor!

Mr. Hu's strength lies in the fact that he never pays for things himself......

Generally speaking, the other party still has to ask him for money, and then he has to hold his hand, speechless and choked. One last sentence -

"Good man!"

Leonard, Simon Clay, Bill Heutley......

A group of people in the anti-IBM coalition were all stunned to see this thing operated by Hu Wenhai, and in the conference room of Loyle's company, an entire wall was filled with a grid of frame cabinets.

I saw Hu Wenhai lift a flat rectangular metal box no more than 20 centimeters from the corner of the wall, and then carefully stuffed it into the frame cabinet as if it were a drawer.

I saw the indicator light on the metal drawer that was tucked into it flash, and then it began to stay on. Rows of code suddenly appeared on the monitor on the conference table, and Simon Clay, who was sitting in front of the monitor, tapped and waved his fist excitedly: "Okay, the system has loaded a new 'drawer' and can enter the parallel computing network!"

Everyone in this room is a big guy who can make an earthquake when they stomp their feet in the computer industry.

However, they were like a group of children at this time, looking excitedly at the cabinet that occupied an entire wall. At this time, the cabinet wall was only a quarter of the area, and most of the places were still empty.

However, even so, these "big shots" still laugh like a child.

Looking through the "drawer" opening of the cabinet, dense connecting wires appear on the back panel of the cabinet. As the data flows, the lights on these backplanes blink like stars.

The stars of these data eventually converge here to form a galaxy of data.

"I call this server composition model a drawer server, which concentrates the most basic PC functions on a single motherboard, which can integrate computing resources and greatly reduce the cost of increasing computing resources. ”

Hu Wenhai talked eloquently, introducing this thing that he had personally done and spent a week tinkering with. The so-called drawer server, to put it bluntly, is the 80s version of the blade server.

Because the integration and volume of the blade server cannot be achieved, the computing unit can only be made into the same volume as a drawer. However, this does not affect the flexible deployment advantages of drawer servers, which are the best choice for low-cost, high-compute commercial servers like blade servers.

This thing looks like a high-tech thing, but to put it bluntly, it still stands on the shoulders of giants. The data preprocessing is DEC's minicomputer, the data transmission technology is provided by Cisco, HP contributed a low-cost motherboard and computing architecture, and Apple contributed rich computing resources under the 68000 architecture.

Hu Wenhai's own contribution is mainly two, one is to integrate the forces of various anti-IBM alliance members, and the other is to contribute hot-swappable technology.

Of course, hot-swapping is not a new technology in the first place, and it has been widely used in the mainframe field for a long time. Not to mention anything else, the legendary level of three vacuum tubes per minute in Ainiak, if there is no hot swap, will the mainframe still work?

What Hu Wenhai has to do is to transplant the hot-swap technology to the PC system of the "drawer server".

If he didn't have any foundation, he wouldn't have been able to get this walled drawer server for ten years. But with the support of almost the entire American computer industry, his job is not too simple.

Drawer server, this is Hu Wenhai's fatal blow to IBM.

Well, although I'm embarrassed, it's also a fatal blow to Simon Clay's vector machine system.

However, in the 80s, Simon Clay had already realized the limitations of vector machines and considered parallel computing. It is precisely because of this that he is the person who is most shocked by Hu Wenhai's achievements among the people present. As the so-called experts know whether there is a shot or not, some skills are not how superb they are, but that their ideas are not open. If no one wakes up, I'm afraid I'll never figure it out.

Obviously, the design of Hu Wenhai's drawer server will profoundly change the entire computer industry.

With the advent of blade servers, the hardware design of supercomputing has become a game of stacking blades and challenging the bandwidth of switches. In this way, the prelude to the supercomputing arms race can be regarded as a complete opening.

The world that follows must be a history of supercomputing constantly pushing the limits of computing speed. In such history, Simon Clay, the father of supercomputers, will be like a fish in water!

DEC's Olson saw the data processing minicomputer market required by drawer servers, HP saw the huge demand for "drawers" for drawer servers, Leonard saw the development of the switch market by parallel processing of drawer servers, and Steve Jobs saw the application direction of Macintosh's huge software resources under the 68000 system......

In this system, except for the absence of IBM, almost all PC manufacturers see their own bright future.

Of course, the most important thing is that the end user will no longer have the "right to vote with their feet" on the development of hardware. In server-to-terminal mode, server configuration will become a feast for some of the industry's cakes.

Well, the liberal alliance that we gathered to bring down the evil hegemon IBM is definitely not the prototype of an industry monopoly association!

That's what I said, but no matter how you look at this group of people, the laughter is so insidious! (To be continued......)
