Chapter 1926 Initial Exploration
In the old time and space, this is not a big problem. Generally, the server room has multiple data backups. If the hard disk is broken, you just need to buy a new one. But here, the hard disk is a very valuable thing as a precious data storage carrier.Once the hard disk is damaged and there is no backup, it means that part of the knowledge is completely lost.Feng Nuo had to wait carefully.Extract the maximum value of each hard drive.

The old personal computers began to fail and irreparably damaged, and those that were not broken also had different degrees of wear, aging, and failure of accessories. Although the high-performance/large-capacity clusters of computing centers and data centers are still operating normally, they A steady stream of guarantees keeps the server running for another 20 years.

The computing center that the veterans brought along with the ship consisted of several sets of blade servers, and several fat nodes, with a high-speed disk array with a capacity of tens of terabytes as storage.The data center is a small number of service nodes and ordinary disk arrays counted in P.There is also a tape drive backup system.

The equipment was not plentiful, but the total investment also exceeded tens of millions—no matter how many old people's homes could afford it, after all, all walks of life were asking for money and quotas at that time.If the computer system did not carry a huge reserve of knowledge, it would be a "luxury toy" in the eyes of some veterans.

Because it is basically impossible to manufacture such things as computer components in the lifetime of the veterans, the storage and use of equipment are also carefully calculated.

According to the relevant orders issued by the Planning Institute implemented in the past few years, one set (piece) of all equipment must be set aside and transported to Gaoshanling as the original standard equipment template and sealed up, not included in the available reserve.Therefore, Feng Nuo reduced the number of operating units and only ensured the necessary operation.Now there is a set of images of the data center placed on the side of the big library.Feng Nuo's equipment here barely maintains normal operation.

In the early stages of time travel, the computing center did not do enough protection measures such as moisture-proof, dust-proof, anti-static, and constant temperature, which will affect the life of the equipment to some extent, especially the hard disks in the disk array.

Theoretically speaking, the operating life of the server is very long. It is very common to run for seven or eight years without shutting down. If it is properly maintained, there is no problem running for more than ten years.Of course, the premise is that there is sufficient maintenance, especially the timely replacement of accessories. This is why the server needs to support hot swapping.

Because it is necessary to ensure the hot backup of all cluster disk arrays as much as possible, Feng Nuo only uses half of the blades at the moment.Then take the way of rotating and regular starting to prolong the life. The computing center is opened every two months for two months.The data center is turned on and running with the mirror image on the big library side.

Speaking of it, the data center is actually more important than the computing center. The computing center is mainly used by people in the industrial and military industries. There are fewer large-scale computing tasks in other fields, and most of them are done on veteran personal computers and small department-level servers. up.The data center is an inseparable place for all departments. For the ownership and management of the data center, the large library and the Planning Institute have torn it up several times. The large library believes that their core resources are actually the content of the data center. , while the Planning Institute adheres to the principle of centralized management and centralized use, requiring the computing center and data center to be put together.

The two quarreled with the executive committee, and finally the indexing, management, review, and review of data content were still returned to the big library, and the Planning Institute was only responsible for software and hardware maintenance.Later, when preparing for the second anti-encirclement and suppression campaign, a set of mirror images was transferred to the large library for offline operation. Firstly, it was used as a safety backup, and secondly, it was convenient for the large library to compile indexes and plan the "data paperization" project. The power supply has also stabilized.

The data center originally planned that three sets of mirrors would back up each other and operate in the current mode of starting up in turn. It is estimated that there will be no problem maintaining it for another 3 to 10 years.It is worth noting that the mobile hard disks carried by individuals have recently started to break down. Feng Nuo can repair simple computer problems, but if the hard drive is completely broken, Feng Nuo has no data recovery skills.

The same worry as the hard disk is the memory.Fortunately, this thing is small in size, and they still have a lot of memory particles stored in sealed deoxygenation.

All signs indicate that the data and information processing capabilities that the Senate is proud of have begun to decline.Feng Nuo felt that the hat on his head and the guy who was eating were not stable.

At present, the "de-informatization" of the Senate has been carried out for several years, and it has been quite in-depth. Not only have a large number of important technical materials and cultural and historical materials completed the work of Chinese culture, paperization and indexing, but also the business exchanges of various departments have been completely completed. Separated from computers and networks; new office buildings are no longer equipped with wired and wireless networks, and veterans are gradually no longer using USB flash drives or emails for private and business information transmission; fewer and fewer people speak on bbs, "Weekly News" and "Venus" is getting thicker and thicker; "Nature and Science" has changed from the earliest monthly magazine to today's weekly magazine, and even after the relevant agencies of the Executive Committee moved to the county, their work efficiency has improved slightly.

It can be said that even if all the computer equipment collapses immediately, the Senate can continue to maintain it. Of course, the duplication of the technology tree will be hit in the eyes. After all, it is not realistic to put all the PB-level data into paper. The most critical technical information is preserved.After the start of the Second Five-Year Plan, the Planning Institute, the Science and Technology Port and the Industry Portal have been working out the medium- and long-term technology and industrial development plans of the Senate, that is, the technology trees for the next 20 to 50 years have been roughly determined, so that the needs can be clarified. Carry out the next step of paperwork of technical data.

As for computing power, the Senate still has the last batch of reserves.In the dark and hypoxic planning institute's super-controlled product warehouse in Gaoshanling Cave, there are several tightly sealed containers.The "final stock" of the IT group is preserved with lime desiccants and iron powder antioxidants that are replaced regularly.They are all tightly sealed in special packaging.Most of them are WeChat single-chip microcomputers for industrial use, and embedded systems, at least in terms of computing and processing capabilities, are definitely enough.The most important thing is that they are light and cheap, and a container can hold tens of thousands of pieces; motherboards for smartphones - there are wholesales from Huaqiangbei, and there are cheaper imported e-waste.The other is a portable scientific calculator.The goal is to ensure that within 100 years, the Senate will have computing power and data processing and analysis capabilities that surpass those of other parts of the world.Before most of the computer systems in the Senate fail, these inconspicuous little things can at least barely guarantee that they can be maintained until the Senate can rebuild the computer industry system - Feng Nuo estimates that it will take about 50 years to be optimistic.

Naturally, Vonno came up with the idea of ​​the predecessor of the computer: the mechanical computer.In fact, the development plan of mechanical computers has a long history. As early as the First Five-Year Period, the industrial port began to imitate the work of hand-operated computers.

Yes, it is imitation.The so-called good ones are bound to be bad. The hand-cranked computer was approved two years ago, but no one asked Feng Nuo if he wanted to participate, and Feng Nuo was always an outsider.This is not a matter for people who engage in computers, it is simply a matter of mechanical design and manufacturing.

"Can a hand-cranked computer be called a computer? At best, it can only be called a calculator!" Feng Nuo thought bitterly, and complained fiercely as soon as he caught his old colleague.Even Feng Shan's ears could hear the callus.

But the imitation business of hand-cranked computers or hand-cranked calculators has not been smooth, and it has not been completely successful until now.At the beginning, the project team of course aimed at the pinnacle of hand-cranked computers - Curta.Before the time travel, the preparatory team specially bought two original products from eBay at a high price, one for Type I and one for Type II.

Disassembled, imitated, failed.

It's no wonder that Curta is only as big as a seasoning bottle, but it is actually composed of more than 600 parts, with extremely delicate design and extremely precise processing.Among them, there are many workpieces such as springs, gears, rollers, etc. that Lingao's current processing technology is not up to standard or immature, and they are extremely small and require high precision.There are even rubber and plastic accessories "which in Lingao can only be replaced with wood and leather.

Although the era of Curta production did not have such an artifact as CNC machine tools, it was completely manufactured and assembled by workers, but there were no such strong workers in the Senate.If CNC machine tools are used for processing, the accuracy can be satisfied, but the material cannot meet the processing requirements at all.

To copy as it is, of course it can't be done, so I have to settle for the next best thing, enlarge and copy.

As a result, the successfully replicated sample was the size of a bucket.Not only is the position of the rocker no longer reasonable, but the human power is almost immobile.Self-weight is a problem, not to mention portable, it is difficult to move.Because the tolerance does not meet the requirements and the mechanical strength of the material is weak, it is severely worn during the test.

In the end, only a few enlarged copies of Curta were made and sent to the Human Computing Center. At least calculating the four arithmetic operations with a dozen digits, as well as reciprocals and square root is more powerful than an abacus.So when it was first delivered, it aroused the amazement of the naturalized human resources calculator.However, it is obvious that this thing is a serious waste of manpower: in order to be able to use it for a long time, it must be equipped with one or two full-time rocker hands and calculators to cooperate, otherwise the calculators will soon be exhausted.

The next step is to copy the earlier desktop hand-cranked computer, and the object is a "cultural brand" hand-cranked computer.

The types of hand-cranked computers produced in Yuanshikong in China were very limited. The most common ones were the "Cultural Brand" of Tianjin Hongxing Factory and the "Flying Fish" of Shanghai Computer Typewriter Factory. The former was "lever type", while the latter was "keyboard". "style", are also imitation of foreign Brunsviga, Felix, Tiger, Marchant, Monroe and other brands of hand-cranked computers, the control methods are different, but the mechanical principles are similar.In the later period, there were also electric computers, but they were changed from manual to electric, saving manpower to shake the joystick.
