Disk array technology, known as discarray, is composed of many disk machines or optical disk drives according to certain rules, such as striping, declustering, interleaving, etc., to form a fast, ultra-large capacity external memory subsystem.

To put it simply, it is to connect many hard disks in series and use them as one hard disk.

For example, what if you buy a computer and use it for a while and you find that the hard disk is not enough? There are two ways, one is to change to a hard drive with a larger capacity; The second is to add another hard disk, and if it is not enough, add another hard disk, so that the capacity is enough.

This method of increasing the capacity by adding the number of hard disks in the computer is a simple disk array technology. Of course, the disk arrays of servers or supercomputers are much more complex.

There are many kinds of disk arrays in history, among which the most famous and widely used disk array technology is called independent redundant disk array RAID, abbreviation of redundantarray of independentdisks.

RAID technology, also known as modular disks, is a technology that combines multiple independent hard disks (physical hard disks) in different ways to form a group of hard disks (logical hard disks) to provide higher storage performance and data backup than a single hard disk.

The use and installation of this technology is simple and convenient, as long as the disk array cabinet is designed, there is no problem, there is no technical difficulty at all.

IBM's business model is the traditional industry-wide hegemony business model, from screws, monitors, CPUs to keyboards, sales, and after-sales maintenance, all of which are one-stop services in place.

This kind of business is very hateful, because you are a company, and you have all the industrial chains related to computers.

In addition, your business is so good, and under jealousy, you have recruited the US Department of Justice, and this is how IBM attracted the antitrust investigation.

Many Asian companies are doing this business model, such as Samsung, Sony, Toshiba, LG, etc., but the anti-monopoly laws of Asian countries are not as strict as those in Europe and the United States, so this kind of trust-like enterprises are blooming everywhere in Asia.

And Ling Shizhe is very smart, he never plays any game of domination of the whole industry chain, he divides the computer industry chain into modules, and he focuses on one of the modules.

And the other modules, whether upstream or downstream, are all outsourced.

This business model is the common business model of European and American enterprises in later generations, and there is a fashionable saying, "doing industry".

Through this "industry" mode of operation, all the upstream and downstream are united to form a huge interest group, which can not only effectively resist business risks, but also block the jealousy of others.

It can be said that Ambrera has escaped the antitrust investigation in this way and has developed to the scale it is today.

But it can't be said that Ling Shizhe is safe, he knows that the judicial departments in Europe and the United States have actually been eyeing him for a long time, and once he is not careful, they will pounce on him like hungry wolves and bite him frantically.

This is also the reason why the electronic products produced by Ambrera must be branded with Apple, and Apple will be independent from Ambrera's system.

I can't afford to monopolize this big hat!

A week after Watson Jr. left, IBM finally arrived.

There were five people in total, three men and two women.

The leader was an old man named Vincent Lierson.

Ling Shizhe inquired about it and learned that he was the third chairman of IBM, and as early as the year before last, that is, in 1971, he replaced Watson Jr., who resigned as chairman due to a heart attack.

An old man who had resigned a long time ago and had a heart attack, who was not recuperating at home, actually came here to play latent, and a dive was more than two months, and finally ran to his company and listened to him blow the cow for a long time......

Thinking of this, Ling Shizhe was even more angry.

Compared with the cunning and domineering of the Watson father and son, Vincent Lierson is obviously much more gentle, which is why he was elected by the board of directors to be the president of IBM, which is now in the grip of an antitrust investigation and urgently needs a moderate company president to save the company's image.

Don't look at Vincent Learson's gentle appearance, he is a typical round and strong personality, and he is not so easy to deal with.

Before Watson Jr. resigned, Vincent Lierson was the first vice president of IBM, a graduate of Harvard University who joined IBM in 1935 and worked his way up from salesman to leadership.

1963 year. IBM's growth was relatively stagnant, with its stock down 33 percent and growth by just a few percent, the lowest since World War II. At that time, Watson Jr. was approaching 50 years old, piloting the huge ship of IBM, and a sense of mission weighed heavily on his heart. After several weeks of anxious thinking, he seized the opportunity of the shining debut of integrated circuits and immediately launched a new research and development project.

During the transition period from formal transistor computers to integrated circuit computers in this year, many people in the company did not support Watson Jr.'s replacement decision, but at this time, Lelson stood up and firmly supported Watson Jr.'s plan, "Do it!" We're going to do it anyway! ”

He formed a committee of engineers to study the program of the new machine, and this group was called the "Committee for Research, Production, and Development of Systems Engineering". This group was later known as the "IBM 360 Computer Planning Group." ”

The 360 program requires a total investment of 5 billion, which is 2.5 times more than the "Manhattan Project" in which the United States developed the first atomic bomb!

On April 7, 1964, on the occasion of the 50th anniversary of the founding of Watson Sr., the "big gamble" of 5 billion yuan won the 360 series of computers for IBM, and began to officially enter the historical stage.

The 360 series of computers was quite successful, and within 5 years, IBM 360 sold a total of 32,300 units, creating a miracle in computer sales and becoming people's favorite computers.

Vincent Learson also became famous for this and is known as the "Father of 360".

In the reception room, after Ling Shizhe shook hands with Vincent Lierson, he looked at the next person, there was a historical celebrity, there are many historical celebrities in IBM, Frank Carley.

He was IBM's fourth president, and in 1973, Lierson spearheaded the development of the company's leadership retirement system, and shortly thereafter he voluntarily resigned, handing over the reins of the company to the man in front of him, Frank Kali.

The third is also a big man, Estlic. He is also the future president of IBM and the famous "father of PC".

The other two women, one is a clerical such as a secretary and the other is a legal adviser to IBM.

On Ling Shizhe's side, Alison, Foster, Andy Grove and lawyer Olsen are also 5 people, and the two sides are sitting facing each other across a coffee table, which is distinct.

The secretary Bai Lu took 3 female clerical staff and poured everyone a cup of coffee.

Ling Shizhe raised his glass, took a sip first, and began to look at the few people in front of him, Vincent Lierson, Frank Kali, and Estlic, all three of whom are famous figures in the history of computers, especially Estlic, who is the "father of PC computers." ”

It seems that IBM is very serious about this negotiation, I wonder what they want to take from us? What can I expect from them? Ling Shizhe thought silently in his heart while stirring the coffee.
