A server is a device that provides data computing and storage services. The composition of the server includes a processor, hard disk, memory, system bus, etc., which is similar to general computer architecture, but due to the need to provide highly reliable services, it has higher requirements in terms of processing power, stability, reliability, security, scalability and Manageability. Servers are classified into computing servers, management servers, and storage servers according to their functions.
Compared with ordinary computer servers, there are the following differences:
The appearance of the case used by the server is generally relatively large. The common case of the server is blade type, tower type, cabinet type, etc. When the purpose is different, the design is also different.
The use of the server is 24/7 and it needs to work 24 hours a day. The Server Room dedicated to storing servers is composed of cabinets. The standard telecom server room environment has requirements for air conditioning, lighting, humidity, uninterruptible power supply, anti-static floor, rack space, and earthquake resistance level.
In the hardware design, more stability and reliability will be pursued. There will also be an emphasis on the configuration of different server types. For example, storage servers require very large hard disk space. If it needs to face large concurrent data processing, its processor will be correspondingly powerful.
The server uses Windows Server Edition, Unix, and Linux operating systems. These operating systems will also be optimized in terms of security, stability, and so on.
