It can be measured from these aspects whether the server has achieved its design purpose: Reliability, Availability, Scalability, Usability, Manageability.
The server must be extensible because the enterprise network cannot remain the same for a long time, especially in the information age. If the server does not have certain scalability, it may not work properly once the user has increased. In this way, a server worth tens of thousands, or even hundreds of thousands, will be eliminated in a short period of time, which no enterprise can afford. In order to maintain the scalability of the server, it is usually necessary to have a certain amount of expandable space and redundant parts (such as disk array rack, PCI and memory bar slot, etc.) on the server.
Compared with PC, the function of server is much more complex. Its hardware configuration and software system configuration are also more complex than PC. In order for the server to achieve so many functions, it must be supported by comprehensive software. However, there are too many software systems, which may lead to the reduction of the performance of the server, and managers can not effectively manipulate it. Therefore, many server manufacturers must not only fully consider the availability and stability of the server, but also work hard on the usability of the server when designing the server. The heat dissipation of server is also more complex than a computer, heatpipe heatsink, 3D vapor chamber heatsink, and liquid cooling solution can be used for heat dissipation of server.
For one server, one of the most important aspects is its availability, that is, the selected server can meet the requirements of long-term stable work and can't be in trouble all the time. Because the server is facing users of the entire network, not a single user, in large and medium-sized enterprises, the server is generally required to be never interrupted. In some special application areas, even if not used by users, some servers have to work on an uninterrupted basis because it must continue to provide connectivity services to users.
In general, specialized servers work on 24 hours a day, especially some large network servers, such as those used by large companies, Web servers, and iqdeWEB servers that provide public services. For these servers, they start only once, that is, the time they are officially put into use, and since then, they work uninterrupted until they are completely scrapped. If the server often fails, it is impossible for the network to maintain normal operation for a long time.
Among the main characteristics of the server, there is also an important characteristic, that is, the manageability of the server. Although the server needs to work continuously, no matter how good the product is, it is possible to fail. Although the server has sufficient guarantee in terms of stability, it should also have necessary measures to avoid mistakes in order to detect problems in time, and in the event of failure, it can be maintained in a timely manner. This not only can reduce the server's chances of error, but also can greatly improve the efficiency of server maintenance.
The manageability of the server is also reflected in whether the server has an intelligent management system, whether there is an automatic alarm function, whether there is a liquid crystal monitor and so on.
