What are the main performance and appearance features of the server? many novices are not very clear about this. In order to help you solve this problem, the following editor will explain it in detail. People with this need can come and learn. I hope you can get something.

The special purpose of the server and its application environment determine that the configuration between the server and PC is different. For junior staff, the appearance of the server can be used to distinguish between the true and false of the server, and these different server appearances contain different hardware configurations and performance. Here are a few appearance features of the server.

i. Large chassis

From the appearance structure, the server chassis is generally larger, although some looks similar to the Xintong PC machine, but in fact it is still larger, even if it is an entry-level PC server. And because the server needs to install more boards and connected devices than the PC machine, so the structure of the server is completely different from that of the PC machine.

In addition, it should be made clear that the general-purpose server is not designed to mislead consumers, it has two main reasons. On the one hand, because the server needs to install and connect many devices, it needs to insert more boards and takes up more chassis space. At the same time, it is also necessary to prepare some spare equipment placement bits, such as tape drives, disk arrays, etc., which also need to occupy space. The server usually needs to be connected to many devices, such as inserting many adapter cards in the server motherboard or dedicated board, some installing several hot-swappable hard drives, and power supplies and fans (commonly known as "redundant power supplies" and "redundant fans"). Generally, there is also a tape drive for system backup to restore. On the other hand, due to the installation and connection of many devices, the heat generated during work is also very large, so there must be enough space to dissipate heat to ensure that the server can work stably for a long time. All these seasons determine that the chassis architecture of the server must be larger than that of ordinary PCs. Even for what some media call DIYPC service cake, in order to ensure its long-term stable work, the chassis must be enlarged. Be careful when choosing or configuring PC servers.

two。 Large hard disk and memory capacity

This is also easy to understand. The server has to face a large number of users and accept the requests of all users, and the operation must install and save many large-capacity server-specific systems, software and other database files, which requires the hard disk capacity of the server to be large enough.

In the past, because the capacity of the hard disk was relatively small (the early ones were only tens or hundreds of megabytes), the disk matrix was usually used to install many disks side by side on the disk shelf of the server and managed by software. Although this was not only used to increase the overall service Gyibug disk capacity, but at that time, increasing disk capacity was also one of its main purposes. At present, the capacity of hard disk has been greatly improved, and the highest one is above SOOGB, so at present, only one hard disk is enough for general small and medium-sized enterprise network servers. The main purpose of using disk matrix is to improve disk performance and redundancy, and to ensure system data security. Of course, for large network servers, such as some portal servers, it is still impossible for their disk capacity to be satisfied by a collar disk, because the magnetic cartridge capacity usually required by this kind of server is at the TB level (1TB=lOOOGB), so it is possible to use multiple disks or disk matrices. And also note that, in order to improve the access speed of the disk, the server hard disk usually uses the SCSI interface and the fast hard disk transferred above I 0000 r/rnin, its transmission rate is now usually above 160Mbps, the fastest is Ultra320, the speed is 320Mbps (it is said that there will be Ultra 640s that support 640Mbps, but at present this standard does not seem to come out).

In terms of memory capacity, it mainly considers the user access speed requirements of the server. Memory determines the running speed of the system to a great extent. The larger and more complex the server network, and the higher the data flow, the more memory is required. Now generally medium and small business servers are above lGB, some high-end servers can support TB-level memory view. Of course, the memory requirements of the server are not only in terms of capacity, but also have special requirements in terms of memory access speed and error correction performance.
