What is the use of servers? Many novices are not very clear about this. In order to help you solve this problem, the following small series will explain it in detail for everyone. Those who have this need can come to learn. I hope you can gain something.

Server is a high-performance computer, as a node of the network, storage, processing 80% of the data on the network, information, the role of the server is relatively wide, online games, websites, some software is needed to save to the server, there are some enterprises will be equipped with servers.

server features

1. Scalability

Servers must have some "scalability" because enterprise networks are unlikely to last forever, especially in today's information age. If the server does not have a certain scalability, when the number of users is not competent, a server worth tens of thousands or even hundreds of thousands will be eliminated in a short time, which is unbearable for any enterprise. To maintain scalability, it is often necessary to have a certain amount of scalability space and redundancy on the server (such as disk array shelf space, PCI and memory stick slots, etc.).

Scalability is embodied in whether the hard disk can be expanded, whether the CPU can be upgraded or expanded, whether the system supports Windows NT, Linux or UNIX and other optional mainstream operating systems, etc. Only in this way can the early investment be fully utilized in the later stage.

2. Ease of use

The function of the server is relatively complex compared to the PC, not only refers to its hardware configuration, but also refers to its software system configuration. It is impossible to imagine a server capable of so many functions without comprehensive software support. But software system one many, may cause the server to use the performance to drop, the administrator cannot control effectively. Therefore, many server vendors in the design of the server, in addition to the availability of the server, stability and other aspects to fully consider, but also must be in the ease of use of the server efforts.

The usability of the server is mainly reflected in whether the server is easy to operate, whether the user navigation system is perfect, whether the chassis design is humanized, whether there is a key recovery function, whether there is an operating system backup, and whether there is sufficient training support.

3. Availability

For a server, a very important aspect is its "availability," that is, the selected server can meet the requirements of long-term stable work, can not often have problems. This is the same as Sun's reliability.

Because the server is facing the entire network of users, rather than individual users, in large and medium-sized enterprises, it is often required that the server is uninterrupted. In some special application areas, even if there is no user use, some servers have to work continuously, because it must continuously provide connection services for users, whether it is at work or off work, whether it is a working day, rest or holiday. This is the fundamental reason why servers must be extremely stable.

In general, specialized servers have to work 24 hours a day, especially like some large network servers, such as servers used by large companies, website servers, and iqdeWEB servers that provide public services. For these servers, perhaps the number of times the real work boot is only once, that is, it has just bought back the full installation configuration and put into formal use that time, since then, it works uninterrupted, until completely scrapped. If things go wrong all the time, the network will not be able to function properly for long. In order to ensure that the server has a high "availability," in addition to the quality requirements of the accessories, the necessary technical and configuration measures can be taken, such as hardware redundancy, online diagnosis, etc.

4, easy to manage

Among the main features of servers, there is another important feature, which is the "manageability" of servers. Although we say that servers need to work continuously, even the best products can fail. To take a common saying, it is not that you do not know when it may fail, but that you do not know when it will fail. Although the server has sufficient security in terms of stability, it should also have the necessary measures to avoid errors in order to detect problems in time, and failures can be maintained in a timely manner. This not only reduces the chance of server errors, but also greatly improves the efficiency of server maintenance. In fact, it is Sun's proposed serviceability.

The ease of management 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 an independent and systematic management system, and whether there is a liquid crystal monitor. Only in this way can administrators manage easily and work efficiently.
