In general, select the server to consider four factors:
A, you first need to consider the server application scenarios: enterprise procurement server, you first need to determine what server is used for, what you need to run software above, our common server can be divided into file server, web server, database server, mail server, etc.,
1, a file server to compare value storage performance, namely when buying a server should attach great importance to the size of hard disk, hard disk bracket;
2, the web server on support for the response, the server memory to reside in response to accommodate many of them, will be unable to support peak of access and lead to paralysis, some sites of paralysis, in many cases are made from the same time traffic, lead to the web page won't open for a long time;
3, the database server is more balanced, need to deal with performance, cache support, memory support, storage capacity and so on various comprehensive performance;
4, the mail server and FTP server on the hard disk storage capacity and responsiveness, attaches great importance to the performance of the hard drive capacity and memory;
Two, secondly, want to consider the performance of the server and compatibility, in general, before buying a server will determine what you want to run the software, how much load, so that you can clearly know about server configuration, CPU, memory, hard disk and so on with how to best, also is to pay attention to the software running on what operating system,
Three, stability and SHOU after service is very important, the server is different from the PC, most enterprise applications require running 24 hours a day, this is the required server must be highly stable, reduce downtime, different brands of server, the outage probability will be different, such as the world's most stable server System X series, at the same time, SHOU after service is also very important, if there is a outage or server in maintenance on some of the problem, how to quickly and accurately solve the problem is the key to reduce the loss to ensure enterprise, therefore, suggest to choose the brand of famous server,
Four, late server extensions, look be like simple, actually a lot of people at the time of purchasing the server did not considering this problem, in general, a server use fixed number of year is 5 to 8 years, during this period, if the volume changes, is bound to lead to changes in the load on the server, if three years later, your company's business volume doubled, then buy server performance is not enough and have to select the server again, very trouble? So if you find that the purchase of the server and the CPU socket, and the memory slot, and hard disk placeholder,
