Three hundred and four chapters initial exploration
In the old days, this was not a big problem. Generally, server rooms had multiple data backups. If the hard drive broke, all you had to do was buy a new one. But here, the hard drive is a very valuable thing as a valuable data storage carrier. Once
Damage to the hard drive and no backup means that part of the knowledge is completely lost. Feng Nuo had to serve carefully and extract the maximum value from each hard drive.
Veteran personal computers began to experience failures and irreparable damage. Those that were not broken also had varying degrees of parts wear, aging, and failure. Although high-performance/large-capacity clusters in computing centers and data centers are still running normally, they
A steady flow of water is guaranteed to keep the server running for another ten to twenty years.
The computing center brought by the elders on the ship consists of several sets of blade servers and several fat nodes, with high-speed disk arrays with a capacity of tens of terabytes for storage. The data center consists of a small number of service nodes and ordinary disk arrays measured in P.
Have a tape drive backup system.
The equipment was not abundant, but the total investment exceeded 10 million yuan - no more nursing homes could afford it. After all, all walks of life were asking for money and loading quotas at that time. If the computer system did not carry a huge knowledge reserve
, in the eyes of some elders, it is completely a "luxury toy".
Because it was basically impossible to manufacture computer components during the lifetime of the founder, the storage and use of the equipment was also very budget-conscious.
According to the relevant orders issued by the Planning Institute in the past few years, all equipment must be set aside and transported to Gaoshanling as the original standard equipment template and sealed up, and will not be included in the available reserves. Therefore, Feng Nuo reduced operations.
The number of units is only guaranteed for necessary use. There is now a set of data center mirrors placed in the big library. The equipment here in Fonnuo can barely maintain normal operation.
In the early stages of travel, the computing center's protective measures against moisture, dust, static electricity, and constant temperature were seriously inadequate, which would affect the life of the equipment to some extent, especially the hard disks in the disk array.
Theoretically speaking, the operating life of a server is very long. It is common to run it without shutting down for seven or eight years. If it is properly maintained, it can run for more than ten years without any problem. Of course, the premise is that there is sufficient maintenance, especially the timely replacement of accessories.
This is why hot swapping is required.
Because it is necessary to ensure hot backup of all cluster disk arrays as much as possible, Feng Nuo currently only uses half of the blades. Then, he adopts the method of rotating startup and regular startup to extend the life. The computing center is opened every two months. The data center
It takes turns to start and run with the mirror in the big library.
Speaking of which, 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. Most of them can be done on veteran personal computers and department-level small servers.
The data center is an inseparable place for all departments. For the ownership and management rights of the data center, the Grand Library and the Planning Institute have fought several times. The Grand Library believes that their most core resources are actually in the data center.
content, while the Planning Institute adheres to the principle of centralized management and centralized use, requiring the computing center and data center to be placed together.
The two companies went to the executive committee, and in the end, the indexing, management, review, and review of data content were still transferred to the big library. The Planning Institute was only responsible for software and hardware maintenance. Later, when preparing for the second counter-encirclement and suppression campaign, it was transferred again.
A set of mirrors are run offline in the big library, firstly as a safe backup, and secondly to facilitate the library's indexing and planning of the "data paperization" project, and the power supply there has also been stabilized.
The data center originally planned for three sets of mirrors to back up each other and run them in the existing turn-on mode. It is estimated that maintaining it for another 10 to 20 years will not be a big problem. It is worth noting that recently, the mobile hard drives carried by individuals have begun to break.
Case study - Feng Nuo can still repair a simple computer problem, but if the hard drive is completely broken, Fon Nuo has no ability to recover data.
The same concern as the hard drive is the memory. Fortunately, this thing is small, and they have a lot of memory particles that are sealed and deoxidized.
All signs indicate that the data and information processing capabilities that the Senate is proud of have begun to decline. Von Nuo feels that his hat and meal are not stable either.
At present, the "de-informatization" of the Senate has been going on for several years and has been quite in-depth. Not only has a large number of important technical materials and cultural and historical materials completed the Chinese culture, paper-based and indexing work, but the business transactions of various departments have also been thoroughly completed.
Break away from computers and networks; newly built office buildings no longer have wired and wireless networks, and senior officials gradually no longer use U disks or emails to transmit personal and official information; fewer and fewer people speak on BBS, "Weekly News" and
"Morning Star" is getting thicker and thicker; "Nature and Science" has changed from the earliest monthly magazine to today's weekly magazine. Even after the relevant organizations of the executive committee were moved to the county seat, the work efficiency has been slightly improved.
It can be said that even if all computer equipment collapses immediately, the Senate can continue to maintain its status. Of course, the copying of the technology tree will be severely affected. After all, it is not realistic to make all petabyte-level data in paper form. At present, it is only possible to think of
, the most critical technical information has been preserved. After the start of the Second Five-Year Plan, the Planning Institute, Science and Technology Department and Industry Department have been formulating the Senate’s mid- to long-term science and technology and industrial development plan, that is, the science and technology tree for the next 20 to 50 years.
Everything has been roughly finalized, so that the needs can be clarified and the next step of paper-based work of technical data can be carried out.
As for computing power, the Senate still has the last batch of reserves. In the dark and oxygen-deficient Planning Institute's special controlled goods warehouse in Gaoshanling Cave, there are several tightly sealed containers. Lime desiccant and iron powder are replaced regularly.
Antioxidants preserve the "ultimate reserve" of the IT group. They are all tightly sealed in special packaging. Most of them are industrial microcontrollers and embedded systems, at least with sufficient computing processing power. The most critical thing
They are light and cheap, and a container can hold tens of thousands of them; smartphone motherboards - some are wholesaled from Huaqiangbei, and some are cheaper imported electronic waste. The other is portable scientific calculators. The goal is to ensure that the Senate will be in power within 100 years.
They all possess computing power, data processing, and analysis capabilities that exceed those of other parts of the world. Before most of the computer systems of 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 -
―Von Nuo estimates that it will take about 50 years to be more optimistic.
Naturally, Vonno came up with the idea of the mechanical computer, the predecessor of the computer. In fact, the development plan for mechanical computers has been around for a long time. As early as the First Five-Year Plan period, the industrial sector began to imitate hand-cranked computers.
Yes, they are imitations. As the saying goes, if there is a good person at the top, the next will be bad. The project of hand-cranked computer was already established two years ago, but no one asked Feng Nuo if he wanted to participate. Feng Nuo has always been an outsider. This was originally
It's not a matter for people who work on computers, it's simply a matter of mechanical design and manufacturing.
"Can a hand-cranked computer be called a computer? At best, it can only be said to be a calculator!" Feng Nuo thought bitterly, and complained about it as soon as he caught his old colleague. Even Feng Shan's ears could hear the cocoon.
But the imitation business of hand-cranked computers or hand-cranked calculators has not gone smoothly, and it has not been completely successful until now. Of course, at the beginning, the project team aimed at the pinnacle of hand-cranked computers-Curta. Before time travel, the preparatory team
I specially bought two original pieces from eBay at a high price, one type I and one type II.
Dismantle, imitate, fail.
It’s no wonder that Curta is only as big as a condiment bottle, but it actually consists of more than 600 parts. It is extremely exquisitely designed and processed with extremely precision. Many of them include springs, gears, rollers, etc. Lingao’s current processing technology is not up to standard or
The workpiece is immature, extremely small, and requires high precision. There are even auxiliary parts of rubber and plastic, which can only be replaced by wood and leather in Lingao.
Although there was no CNC machine tool in the era of Curta production, and it was completely made and assembled by workers, there were no such strong workers in the Senate. If CNC machine tools were used for processing, the accuracy would be satisfactory, but the materials would be completely
Cannot meet processing needs.
Of course, if you want to copy it as it is, you can't do it, so you have to settle for the next best thing and enlarge and copy it.
As a result, the successfully copied sample was as big as a bucket. Not only was the position of the rocker no longer reasonable, but manpower could hardly move it. Its own weight was a problem. Not to mention portability, it was difficult to move. Because the tolerance did not meet the requirements,
The mechanical strength of the material is also weak, and it was severely worn during testing.
In the end, only a few enlarged replicas of Curta were made and sent to the human computing center. At least a dozen digits of the four arithmetic operations and even reciprocals, and square root calculations were better than the abacus. So when they were first sent, it caused a lot of naturalization.
The civilian manpower calculator was amazed. But it is obvious that this thing is a serious waste of manpower: in order to be used for a long time, one or two dedicated rocker hands must be equipped to cooperate with the calculator, otherwise the calculator will soon be exhausted.
The next step was to copy an earlier desktop hand-crank computer, and the target was a "Culture Brand" hand-crank computer.
The types of hand-operated computers produced in China at that time were very limited. The most common ones were the "Wenhua brand" of Tianjin Red Star Factory and the "Feiyu brand" of Shanghai Computer Typewriter Factory. The former was a "lever type" and the latter was a "keyboard".
"style", they are all imitations of foreign hand-cranked computers of Brunsviga, Felix, Tiger, Marchant, Monroe and other brands. The control methods are different, but the mechanical principles are similar. There were also electric computers in the later period, but they were changed from hand-cranked to electric, which saves time.
It's just a matter of manpower to move the joystick.
