How to select the most stable BGP server? What people are talking about now BGP server Most of them are BGP servers with high computing power, which can respond to thousands of customer service requests. BGP The server Although it is equivalent to the commonly used personal computer (PC) in terms of equipment structure, they are quite different in performance and function. So how to choose the most stable BGP server? Today, Micronet will take you to understand the BGP server selection method, hoping to help you.
The "database" and "web service" BGP servers are specially used, while the commonly used personal computers (PCs) are specially used, and desktop computing and terminal applications are specially used. Compared with personal computer (PC), the gap between the two in design foothold makes BGP server have more reliable continuous operation capability, stronger storage capability and network communication capability, more convenient fault recovery function and larger expansion space. In addition, BGP server is also specified to have "data backup function" due to the adoption of BGP server which is very sensitive to data 。
PC (Personal computers) only require one user to provide services for a period of time, while the BGP server needs to carry and respond to the service requests of thousands of users to ensure long-term startup and operation. Compared with ordinary personal computers (PCs), BGP servers need to work continuously within 7 * 24 hours.
Therefore, "stability" is the most important thing for BGP server. BGP server needs to bear the working standard of adult full load, and cannot be restarted randomly like ordinary personal computers (PCs). In general, the sustainable professional ability of BGP servers is mainly determined by MTBF considered (MTBF). The downtime of the BGP server is very short every year. When the reliability of the BGP server reaches 99%, the downtime is about 87.6 hours every year; When the reliability reaches 99.999%, the annual downtime is only 5 minutes.
1. Operating environment
The first is the operating environment. The data center machine room where BGP servers are usually deployed is required to be dust-free, the indoor environment is good, and the temperature is controlled at 4 to 40 degrees above zero, otherwise it will have an impact on electronic parts. The working environment temperature of most electronic information equipment should be between "18 ℃~30 ℃", and the ideal temperature is "26 ℃". If the temperature is too high or too low, the BGP server will be damaged and its aging will be accelerated, thus interfering with the service life of the BGP server. For this reason, BGP servers are usually placed in the air flowing space, with 24-hour air conditioning cooling, used to regulate the temperature and serve them.
2. Operation status
The operation status of the BGP server interferes with its service life. Generally, the CPU load of the BGP server is always above 80%, which will interfere with the life of the fan and CPU to a certain extent. Therefore, the BGP server usually does not work over frequency. In addition, the computer room staff will regularly check the working status of the BGP server hardware equipment, and detect that small problems can be handled on time. Therefore, under normal circumstances, BGP servers can be used for more than five years.
3. Reliable power supply
The BGP server cannot work without the power supply. In addition, the power supply is also the specific cause of the computer problem. The first step is to ensure that the BGP server uses a power supply of appropriate power. The voltage of BGP server power supply is generally 220V/50Hz, and it is growing towards "low-voltage, high-power, high-density, high-efficiency, distributed" and other aspects. UPS (Uninterruptible Power Supply System) ensures that BGP server can continue to work in case of sudden power failure. In addition, the power supply of BGP server is separated from the lighting power supply, and a separate socket is selected.
4. Powerful hardware design
BGP server is also a computer, but generally speaking, BGP server is a very unique hardware facility. Due to the influence of "jobs", many places have made it more "special". In response to the feature of "BGP server reliability prevails", BGP server CPU has built-in fault tolerance and error correction mechanisms; The memory with ECC verification chip is selected as the memory, and the risk of data interference and error is much lower than that of non ECC memory; All BGP servers use pure copper radiators and fins, and the chassis fans are also qualified. The built-in integrated graphics card does not work most of the time; Main boards are all PCB (printed circuit board) with more than 6 layers, and the life span of hard disk is twice that of ordinary hard disk. The development of such hardware provides further strong support for the reliability of BGP servers.
5. Dedicated operating system
BGP server operating systems such as "Windows Server, Unix and Linux" specially developed for BGP server can turn off the service program of graphical interface without external display, so that the operating system of BGP server is not turned on by default. The dedicated operating system brings "high security, high reliability, high availability and high scalability", which makes a major contribution to the reliability of BGP server.
6. Redundancy design
Redundancy refers to repeatedly configuring many parts of the system. When the system has problems, the redundant configured parts can enter and take on the work of the problem parts, thus reducing the problem time of the system. Dual power supply systems are widely used in high-end BGP server products. These two power supplies are load balanced, that is, they both bring power to the system when the system is working. When one power supply fails, the other takes all the load. Many BGP server systems have completed DC redundancy; Many other BGP server products, such as Micron's "NetFRAME9000", complete the full redundancy of AC and DC (alternating current and direct current).
7. Excellent cluster architecture
What if a BGP server in the BGP server cluster has a hardware failure? If the CPU (central processing unit) or memory fails, it is easy to cause the BGP server to shut down. In such cases, the cluster architecture of BGP servers enables multiple BGP servers to apply the same service, and one or more BGP servers go offline due to failure, without serious impact on the overall service.
8. Professional maintenance
According to statistics, financial enterprises lose an average of US $10 million each time of downtime, and the loss of intangible assets caused is also immeasurable. Therefore, professional maintenance is indispensable for the data center computer room where BGP server is deployed. The BGP server has a large amount of backup redundancy under the specified conditions. When it is applied, the operation and maintenance personnel will eliminate the fault on time. Professional maintenance personnel have formulated a series of maintenance systems and post disaster repair strategies, which provide logistical support for the smooth application of BGP servers.
