In the bright and spacious white room, Qi Yujia passed through the rows of metal cabinets, his eyes looked around, his ears listened in all directions, and he paid attention to whether the sound of each hard disk around him was abnormal when he walked by. Although the control system will automatically supervise all hardware and automatically prompt equipment with poor health, manual inspection is still essential, at least to be able to appear serious and dedicated.

This is his daily routine work, inspecting the computer room, and then maintaining, updating and upgrading the server in the computer room according to the task requirements issued by the management system.

This is the core data room of Bee Technology in Ludao, but it is not on the island, but in the bee garden of the industrial development zone outside the island. This former furniture factory has now become a virtual factory, producing virtual items as large as planets and as small as matches, and these computer rooms are virtual item manufacturing workshops.

The reason why the existing conditions of the original software park IDC were abandoned and chose to build their own computer rooms was because of these cabinets that did not look ordinary.

There are no traditional rack servers or the new and trendy blade servers, but honeycomb servers designed by Atletico Madrid.

Because of this, Qi Yujia and their computer room maintenance team gave themselves a nickname "beekeeper", the real beekeepers patrol and manage dozens or hundreds of beehives every day, adjust the living environment of the bees, and harvest honey, and their work is really similar to these beekeepers, but most of the beekeepers take away from the beehives are honey, and a few are dead bees, and what they take out are pieces of broken or eliminated smart hard disks.

Strictly speaking, this kind of smart hard disk is actually a non-standard custom version of the blade server. They come with their own processors, memory, hard drives, and are independent computer systems, just as each "blade" of a blade server is a separate system. They are also connected to each other by direct data lines and high-speed networks, and the various subsystems of the network are managed by management software, sharing resources and concentrating on specific tasks. Moreover, they also support "hot swapping", which can increase or decrease the number of smart hard disks to enhance or reduce the computing power of the system.

However, smart hard drives can't replace real blade servers, after all, it's just a combination of two or three hundred megabytes of thin architecture mobile phone processors and ordinary PC hard drives, and more expensive blade server units can't compare performance. However, as a data center, smart hard disk has an extremely powerful low-cost and high-performance advantage in the storage field, and all of Bee's games, software, film and television resources, as well as the personal network disk of the garden company are stored in these hive servers.

Originally, according to the flat shape of the hard disk, these PC hard disks with a specially modified mobile phone motherboard are most suitable for centralized installation in a way similar to the hard disk rack of a data warehouse. However, Atletico Madrid's whimsical idea did not choose the common parallel arrangement to install these hard disks layer by layer, but let them form a "Y" shape in a group of three in the form of an angle of 120?, and then finally assembled into a hexagonal stacked structure similar to a honeycomb, and found a honeycomb in a veritable way.

The reason for this is not only to live up to the name, but also to enhance heat dissipation.

Usually, the heat generated by mobile phone chips and PC hard disks is not too large, and there is no need to configure additional heat sinks such as fans during normal use. However, due to the dense accumulation of a large number of chips and hard disks in a small space, the overall heat generation of the honeycomb system is greatly increased, and the heat dissipation pressure is generated.

The hexagonal structure itself has a turbulent effect on the airflow to maximize heat dissipation, and the hexagonal structure of the hive is not an intelligent choice for insects and bees, but a "natural selection" after their high body temperature and high density agglomeration.

Moreover, the hexagonal structure, as the most material-saving space structure, can also ensure that each smart hard drive has the largest free space on both sides for installing additional heat sinks.

Because of the use of a centralized water cooling system and a battery DC power supply system, there is not a single fan on this kind of honeycomb server, and there are only thousands of mechanical hard disks in the entire computer room that rotate at high speed and the weak sound emitted when the head is positioned.

Qi Yujia is carefully identifying these sounds, once there is something abnormal sound, it means that the hard disk there is faulty or hidden danger, and it needs to be maintained and replaced, he will use the marker pen in his hand to leave a mark on the label card corresponding to the abnormal sound hard disk, and then he will push the trolley over to replace them one by one. In fact, there are very few hard drives that he can usually hear with his ears, after all, he is just an ordinary person, and his ears are not as sensitive as those of tuners or blind musicians. Most of the time, they rely on the list of unhealthy hardware provided by the management system for replacement operations.

Since the establishment of this computer room, a batch of new hard disks has been sent in every week to be installed, and every other section, there will be damaged and scrapped or degraded hard disks to be removed and sent out.

This is the sadness of mechanical hard disks, although theoretically unlimited life, but in fact affected by the life of mechanical components such as motors and heads, they are prone to such and such problems under the high-frequency and high-load operation of the server environment. For the sake of safety and stability, it is necessary to investigate in time, and then disassemble and eliminate it. Coupled with the fact that business expansion will require larger and faster hard drives, they can sometimes be very busy.

This frequency is not fixed, and it is related to the company's business development, so their work intensity varies greatly, sometimes they are very idle and may only need to turn a few times to do things, and sometimes they will be very busy, and even need to work overtime.

Usually there is a salary for free time, and there is overtime pay for overtime, so Qi Yujia and they are still very satisfied with their work. But that's changing as the company gets bigger and richer, and the price of hard drives stabilizes. The daily routine adds some work to install new hard drives on new servers, and there are far fewer sudden overtime breaks.

If it weren't for the fact that the mobile phone chips on the smart hard disk are still being upgraded and the price is also decreasing, the company has no incentive to build a data center in place at one time, and their daily workload may be even greater.

Most of the mobile phone processors on the bee smart hard disk are second-hand recycled goods, but because there is no mechanical wear and tear, they have been carefully inspected before installation, and the current operating environment is also very "comfortable", so even under long-term high-load operation, there are few chip problems and reimbursement.

However, even if these second-hand chips are "old and old" can fight for another 500 years, but after all, "the waves of the rivers and lakes push the front waves, and a generation of new people is better than the old people", with the new chips with higher performance and cheaper being continuously sent into the company, some old models of mobile phone chips will still be eliminated from time to time in the computer room.

These eliminated smart hard disks have become the harvest of Qi Yujia and their "beekeepers".

After completing today's update work, Qi Yujia pushed the trolley to send the smart hard disk taken out from the computer room into the testing room, where colleagues will separate the mechanical hard disk and the mobile phone chip and test them separately. Physically damaged hard drives and chips are sold to recycling companies, but the hard drives sold to protect data confidentiality are required to disassemble and destroy disk chips.

The mechanical hard disks and chips that function properly after testing will be reassembled into smart hard disks, flashed to the normal version of the system, and sold within the company.

There are two modes of bee's smart hard disk, one is C mode, also known as computing mode, where the on-disk chip undertakes more computing tasks, and the other is S mode, storage mode, where the on-disk chip only undertakes intelligent read/write acceleration tasks. The smart hard disk in the computer room has two modes, usually the chip with a higher frequency is C mode, and vice versa, but the ordinary version of the smart hard disk is in S mode, regardless of the performance of the chip it is equipped with.

The smart hard drives sold in-house by these companies are highly praised for their low price and powerful performance, as they are shredded and carefully tested for their data shredding and careful testing, and will not be leaked or interfered with normal use. Not only the company's employees use it themselves, but many people also buy it to give to relatives and friends, or even sell it to others.

The company does not prevent this situation, but thinks it is a good thing for the environment.

Usually, after the used mobile phone is sold to the person who recycles the old mobile phone for tens or even a few dollars, it will be sorted according to the model and then broken down into parts. Part of the parts available for testing flow into the repair market of the model of mobile phone, and part of it flows into the mobile phone accessories market, and finally it is installed in the copycat mobile phone. There are some more tragic ones, which will be dismantled and alchemized.

It's really alchemy, refining gold from electronic chips.

Gold is not the metal with the best conductivity, and even can only rank third, at 20C room temperature, the order of metal conductivity increases sequentially is silver< copper< gold< aluminum< tungsten< nickel < iron. However, gold is the most popular high-grade conductive material used in the electronics industry, because silver and copper, which have a higher conductivity than gold, and aluminum, which is second only to gold, will be oxidized due to long-term exposure to air, forming a high-resistance oxide film on the surface to change the resistance of these materials, which will have an impact on the signal processing of electronic products.

Gold is stable and does not oxidize in the air, so engineers are keen to use gold to make connecting wires and connector jacks to ensure stable and accurate signal transmission. In particular, the core of various CPUs is a laser-etched semiconductor silicon wafer, but the periphery that connects the silicon wafer to the packaging circuit is an equally thin gold wire.

The fact that some chips contain gold has attracted the attention of the waste materials recycling industry and various professional collectors, who bought some obsolete electronic waste at a low price, soaked it in strong acid after dismantling, and really refined gold. One kilogram of IntelCPU can smelt 3 grams of gold, which costs a few hundred yuan.

This kind of dismantling method harms the body and pollutes the environment is not tolerated by law, so no one in major developed countries usually does not engage in this business, and they would rather dismantle warships. In order to deal with e-waste, these countries will even "export" them at a discount, and this waste does contain valuable metals such as gold, silver, copper and aluminum, so people in the coastal areas of underdeveloped countries with lax environmental regulations have seen this business opportunity and have started this simple business of getting rich.

So much so that the e-waste that used to need to be exported can be sold for money......

Bee Technology is also one of the "gold diggers" of a large number of waste chips. However, others are looking for specific models of chips to take to alchemy or to repair and refurbish popular models of electronic products, while they are working with a professional recycling and dismantling team to use second-hand chips with intact structures and functions to manufacture smart hard disks for the construction of their own computer rooms.

As a storage application, a certain amount of second-hand mobile phone chips that meet the quality standards can be used, but second-hand goods cannot be used in ordinary computer rooms, because the chip industry is developing rapidly, and it will always be a generation of new chips that is better than old ones on the road of pursuing faster, stronger and more capable. Unless the new product does not achieve the expected effect for various reasons, the new generation of chips will inevitably be more power-efficient, faster and cheaper than the old-timers.

Of course, if you always pursue the "best" and "strongest", if you don't buy non-top flagship products, the word "cheap" should be insulated from you, because the top models of flagship products are always all kinds of expensive and expensive.

Therefore, it is not surprising that Bee Technology, which is accustomed to picking on doors, would choose such a slightly strange server. The motherboard does not save money, in order to enhance stability, it uses server-grade products, but the power supply is replaced by a high-performance battery to reduce AC and DC conversion heat and prevent power outages, which is said to be the legendary Google experience.

Although the memory and hard disk in the configuration are not the most high-end, at least they are first-class. But the blame is on the CPU models, and some of the server units even use low-end Celeron processors. Not only the CPU is in the situation, but the number of graphics cards installed on some rack servers is also wrong, which is obviously too much.

Xu is used to being poor, Atletico Madrid prefers to configure servers with higher cost performance, but they don't care much about the strong stability and high reliability claimed by high-end server products in the industry, and even poor performance can be reluctantly accepted, as long as it is cheap enough.

That's why the low-end Celeron CPU has entered the Bee's computer room in a grand manner, because the Celeron with the same process has a lower cost of computing power procurement.

Similarly, a large number of graphics cards enter the computer room, also because of the cost performance, using a graphics card GPU that is more good at floating point computing to join the server, can greatly improve the calculation effect of various physics simulations.

The use of graphics cards for general-purpose computing is becoming popular internationally. In the past, researchers cracked the graphics card driver, so that the GPU of the graphics card, which could only render pixels, could be used to calculate other similar mathematical problems such as diffusion solving, and the effect was better than using a CPU of the same price. And now graphics card manufacturers and game companies have realized that the time has come for graphics cards to use general-purpose computing to replace some CPU functions.

Microsoft's DirectX10 graphics interface, which was released with Vista, allows programmers to perform more general-purpose programmable calculations on the graphics card. And graphics card manufacturers are not to be outdone, graphics card giant DIA released a female Diatesla general GPU computing solution in June, the core is GeForce8 series architecture GPU. Its dedicated CUDA program is capable of processing thousands of threads at the same time when executed, bringing more efficient computing performance to some compute-intensive tasks, allowing the GPU to quickly solve some complex computing problems.

Although Bee said that its own server cannot be used to predict the medium and long-term prediction of real-time global weather simulation in the country, it does not mean that its own server will be inferior to the National Weather Bureau's group of supercomputers ranked first in the country.

After all, the Meteorological Bureau is a public institution, and they need a budget and appropriation to buy things, and it is impossible for them to be as independent as bees.

After the release of the Tesla plan and the CUDA development kit for women's dia, Atletico Madrid immediately paid considerable attention to it. And after the actual test was effective, he soon invested tens of millions of dollars to wholesale thousands of G92 core N cards to build his own server of "Daming OL". That is to say, the seven "Daming OL" servers in the six regional computer rooms of the bee and the core computer room of the headquarters are the world's first large-scale use of graphics cards to build a general-purpose computing platform, temporarily proud of the world's supercomputing with the same investment cost in the field of scientific computing and physical simulation.

This move once sold out the mid-to-high-end N cards in many parts of the country, and contributed a lot of topics and layouts to several major IT portals. Similarly, it is also because of the addition of this batch of "cost-effective" graphics card supercomputers that Bee can have the confidence to start the public beta with unlimited numbers and undeleted files in July.

Of course, whether it is the national supercomputing TOP100 or the global supercomputing TOP500, the game server that Bee uses a large number of graphics cards is actually not on the list at all, this is because the proposal of Bee Technology to contact and register computing power to be on the TOP100 list was suppressed by Atletico Madrid because he felt that it was unnecessary.

Although with the current floating-point computing power of these seven sets of servers, it is barely qualified to be on the TOP100 list, but this is caused by Atletico Madrid's failure to optimize it. After all, the game company's server is ranked in the national supercomputer rankings, how do you look like a slap in the face, and that's why the old Zhu Xian, who loves to play ball, will do such a veryzhuang forced lity thing when it hurts.

If it is really optimized according to the domestic and international fashion trends and specifically for the supercomputing ability assessment program, Atletico Madrid believes that it can completely dominate the top 100 of the TOP100.

The reason why bees can't calculate weather simulations is not because the server is not good, but because there is no relevant data. The weather temperature and wind forecasts for each region are presented to the public, and the meteorological bureau calculates these data on the basis of the network data of hundreds or thousands of weather stations across the country, as well as the cooperation and sharing of data from other neighboring countries within the World Meteorological Organization.

In addition, Atletico Madrid's insights in fields such as atmospheric physics are not very profound, so they do not want to build their own real-time weather system, and instead directly use the national weather data interface of the National Weather Administration.

In fact, with the consumption of at least 1,000 high-end graphics cards in each computer room, these supercomputers of Bee are properly proud of the country in the field of physical simulation, and should be able to barely squeeze into the top ten in the world. However, if you include the supercomputing of the wealthy United States and NASA space agency, it may fall to 20 or later. Atletico Madrid doesn't know exactly how much, after all, he has nothing to do to go to the Black Pentagon's intranet. For mobile phone users, please visit http://m.piaotian.net
