It is believed that the development of network technology is subverting all aspects of people's work and life, whether in the current information society or the upcoming digital society, and the convenience it brings to us is beyond doubt. However, in our daily work and life, we often hear the word "server", but this familiar term, like a stranger, has never appeared in people's eyes, which makes many friends doubt what "server" is? What's the use of this?
As we all know, the computer room is an important resource for server hosting providers. To select a reliable server hosting provider, we must investigate and investigate IDC's computer room. Today, Micronet will join you to understand the necessary server guarantee conditions for the computer room, so that when we investigate the computer room, we can understand what are the key points of the computer room and what must be investigated, Comprehensively consider the industry level of IDC service providers.
First, the definition and functions of the server are as follows:
The official definition explains that the server is a high-performance computer. As a node in the network, it stores and processes 80% of the data and information in the network, so it is also called the soul of the network. However, it can also be said that the server is a kind of computer software that manages resources and provides services for users. It is usually divided into file server, database server and application server. The computer or computer system running the above software is also called the server.
Compared with ordinary PCs, servers have higher requirements for stability, security, performance, etc. So unlike CPU, chipset, memory, disk system, network and other hardware, ordinary PCs also have better performance than processors.
The functions of servers and computers are the same. We can also call servers computers, but servers have higher requirements for stability, security and data capacity of processors.
The server has a wide range of functions. Online games, websites, software, etc. need to be stored on the server. Some enterprises will be equipped with servers, and their important materials in their daily work are all in the hard disk of the server.
Second, the role of the server in life
The server is like a node of the network, storing and processing 80% of the data and information on the network, so it is also called the soul of the network.
To make a vivid analogy: servers are like post office switches, while fixed or mobile network terminals, such as microcomputers, laptops, PDAs, mobile phones, are like telephones, scattered at home, in various offices, in public places, and so on.
The telephone exchange and communication between us and the outside world in our daily life and work must go through the exchange to reach the target telephone; Similarly, network terminal devices such as families and enterprises also need to access the Internet to obtain information, communicate with the outside world, entertainment, etc. All must pass through the server, so the server "organizes" and "leads" these devices.
It is a highly available computer on the network, which can provide multiple services for clients. Under the control of the network operating system, hard disks, tapes, printers, modems and various special communication devices connected to it can be provided to client sites on the network for sharing, and can also provide network users with centralized computing, information publishing, data management and other services.
Its high performance is mainly reflected in high-speed computing capability, long-term reliable operation, strong external data throughput, etc.
Why does the server need to run continuously?
Because people are surfing the Internet day and night, we must turn on the computer! If there are internationally renowned websites, this is even more true. It is almost impossible to stop. Once the service is stopped, the consequences will be unimaginable.
Generally, servers need to be powered on 24 hours a day, and occasionally shut down for maintenance.
Why the server runs continuously
Since the server needs to be powered on 24 hours a day and work uninterrupted 365 days, heat dissipation is more important. Therefore, the server needs to be placed in a relatively stable and suitable environment. Constant temperature, humidity, dust prevention, power supply, etc. are essential. Machine room, air conditioning room, constant temperature and humidity, dust-proof, ensure power supply.
Server classification:
According to different architectures, servers can be divided into two categories:
A non x86 server:
It includes mainframe, minicomputer and UNIX servers, which use RISC (Reduced Instruction Set) or EPIC (Parallel Instruction Code) processors, mainly UNIX and other special operating systems.
Simplified instruction set processors mainly include IBM's POWER and PowerPC processors, SUN's SPARC processor developed in cooperation with Fujitsu, and EPIC processors are mainly Itanium processors.
This kind of server is expensive and closed, but its performance is stable. It is mainly used in the core systems of large enterprises such as finance and telecommunications.
Two x86 servers:
Also known as CISC (Formed Corporation System, usually called PC server), is a PC based architecture that uses Intel or other processor chips compatible with x86 instruction sets and Windows operating system servers.
Cheap price, good compatibility, poor stability, low security, mainly used for small and medium-sized enterprises and non critical businesses.
server room Factors to consider
1. Stable power supply is a necessary condition for the normal operation of the server, and also the basis for the server to serve the enterprise. Therefore, when we configure the power system of the machine room, we need to consider the normal operation of the server under the normal power supply situation, as well as the response measures in case of emergencies. For example, in order to ensure the security of server data, a large UPS distribution cabinet with high specifications needs to be configured in case of sudden power failure to ensure that the server can continue to operate for a period of time after power failure; For example, pulling a cable for the server room to supply power separately from other facilities is also a measure for the server to maintain power stability.
2. The stable operation of the server also requires temperature control. If there is no temperature control equipment, the CPU temperature of most servers is generally above 60 degrees when they are running. The high temperature in hot summer will affect the performance of servers if they are in a high temperature environment for a long time. Therefore, the server room generally requires to be equipped with precision air conditioners, which can be used to control the ambient temperature of the machine room between 18 and 25 degrees to avoid the continuous operation of servers in a high temperature environment.
3. Humidity also has a great impact on the server. If the humidity is too low, it is easy to generate static electricity, which will lead to the breakdown of capacitors or other chips if you are not careful. If the ambient humidity is too high, it may condense on the circuit, causing the circuit insulation performance to be reduced or even short circuited. Long term humid environment will cause mold breeding and damage the server's circuit system. Generally, the humidity of the server room is required to be controlled at 45%~55%. If possible, the cabinet should be overhead, and moisture-proof materials should be laid under the floor.
4. Dust is the killer of all electronic devices. For example, a large amount of dust covers the main board circuit of the server, which is easy to cause short circuit; Attaching to the cooling fan will also increase the load of the cooling fan and affect the cooling effect. Therefore, the server room must take dust-proof measures, such as wearing disposable dust-proof shoe covers or having special slippers for the computer room when entering the computer room. At the same time, the server needs to be dedusted regularly; Try to avoid long-term opening and closing of server room doors and windows.
5. Fire prevention and lightning protection measures shall also be taken for the machine room. Although the machine room requires the use of thermal insulation and refractory materials, protective measures such as purchasing high standard sockets, banning smoking in the machine room, and equipping with fire prevention equipment must also be taken. If possible, independent sensors must also be installed. The server and other electronic devices are very sensitive to current pulses. Therefore, lightning protection measures must be considered when arranging the server room. Transient high current pulses in the circuit may break down the server.
6. Other matters needing attention. It is not allowed to be exposed to the sun for a long time. The sun will cause the server surface temperature to rise; Too many servers cannot be placed in one cabinet because of the limited bearing capacity of the cabinet; When arranging the server room, a long-term plan should be made. The ventilation of the cabinet and the location of the distribution frame should be planned in advance to make better use of space and facilitate management.
After proper maintenance, the server can effectively extend its service life, improve work efficiency and performance. After all, like the servers in the Micron Network room, they generally serve us 24 hours a year.
