I am tired of doing the website, write an article easily, and start to write the fourth article I am outdated. The keyword in this article is server. When it comes to servers, It is very relevant to everyone. websites have to be related to servers. I may not be so right, but some of my experiences may be outdated. If something is wrong, I hope you can correct me. A server is a machine that provides services. There are many types of services, such as printing servers, file servers, and database servers. Different services have different requirements for machines, even a 586 machine can act as a server. Of course, the function is simple. It is very strong to install a UNIX route. The first topic is to select a server based on your needs.

Many people now host their own machines, most of which are assembled with 1U machines. In some people's eyes, they are just high-end household machines. Servers are mainly used to experience data security and system stability. Brand servers focus more on dual power supplies and hot swapping of hard disks, but these are difficult to achieve in 1U machines assembled by ordinary people. These are the main differences, but we are not big companies with rich people. According to the principle of the black and white cat, no matter what the black and white cats do, it is a good cat to catch the mouse, so no matter what the configuration is, we can implement the service function, the desired service is a good server.

Don't waste it. If you choose a server that is enough for your use, it is a waste of resources. People now have money and can't move on to build a dual-Xeon, but later found that the website often cannot be opened. I really thought that my traffic was very high, but it was not necessarily. You need to know whether the website is slow and the first response is a North-South problem. That's right. The reason why the website is slow is that its website is faulty and its resources are insufficient.

Speaking of bandwidth, it is necessary to talk about the data center here. If you want to rent a server or host it, you must pay attention to it. Shared by MB. There are many articles in this word.

　　 First, the access switch Layer

The network layout of the data center is generally a route, which is connected to a gigabit switch, then to the layer of a 10-Gigabit switch, and to the rack switch, how many routes are there between a server and the router, only engineers in the IDC room know that a regular IDC room does not allow guests to access the primary switch room or open others' cabinets. Your company can only open your cabinets.

　　 Second, number of shared machines

As an IDC, they wish to make the server into the size of a notebook, so that he can put several more machines in a cabinet. Fortunately, the current server is not as low as the technology, but as high as the cost. If it is used, it cannot make money, so it is useless. According to the cabinets in the current data center, there are generally 48U cabinets, which can be placed with 24 machines. There is a shelf between the machine and the machine, and there is a heat sink in the middle, so there are 24 machines, however, I cannot guarantee a maximum of 24 servers. There is a black-hearted IDC, and even the space will not be spared, and 30 servers will be placed directly. If you have two download and movie sites in your data center, and the switch cannot control the volume, you might as well access your home's ADSL.
