20,000-yuan Tower server purchase analysis performance plus expansion

21st Century server has become a necessary enterprise equipment, many enterprises began to use the server to store enterprise information, deployment of Internet servers, http://www.aliyun.com/zixun/aggregation/14291.html "> Print server and high-performance application server, and so on, for the storage server, the general server hardware performance requirements are high, only need to have enough hard disk capacity, and for application-level server is different, according to different aspects of the application of the server's hardware performance requirements are not the same, Some application server may also need two or even more servers to work together to achieve a good job, that enterprise users how to buy more suitable for their own server it?

First of all, for the enterprise deployment application-level server, first of all to determine their deployed application services to the server hardware requirements, if the requirements of the lower completely can buy entry-level servers, if the requirements are high, you need to buy more powerful high-end server. Below we have to ask for a higher application services to analyze how the enterprise to choose the application server.

Once you have identified the requirements for server performance for your deployed application services, the first thing you need to do is determine which form of server to apply. At present the server on the market according to the shape to divide, mainly divided into rack-type server, tower server and Blade server three, Blade server has a large volume, its scalability is very good, mainly the use of large enterprises to deploy clustered server; rack-type servers are currently the most widely used Web applications, It has a smaller volume, can effectively save the cost of hosting, but also more suitable for large batch hosting, but its shortcomings are also very obvious, due to small size, in the expansion of the performance is insufficient, the smaller volume also restricts the good performance of its heat dissipation, due to the technical reasons also lead to its price in comparison with some ; The tower server is just the opposite of a rack-type server, its appearance and ordinary PC is quite, has the bigger interior space, the expansibility performance is very advantageous, the larger space also can guarantee the server the heat dissipation, enhances the server the stability, but because of the volume is too big, needs to occupy the larger managed space, Managed costs are much higher than rack-top servers, so they cannot be compared to a rack server in terms of Web applications. We see the superior performance of all types of servers, as an enterprise internal application server, I think that if there is no special requirements, you can consider the tower server, after all, the expansion and stability of the tower server is very good, the future server performance can not meet, but also by upgrading some of the hard drive to meet the requirements, Eliminates the cost of purchasing a new server.

Server processor selection, the current main server processor has Intel Xeon and Itanium, AMD's Hao long processor, but the Itanium processor is mainly used for high-end large servers, in the general application-level server is only Xeon and Hao Dragon to choose from, the performance of the two is not much different from each other, Users can choose according to their preferences.

Memory and hard disk, because of the need to deploy a larger application services, so the requirements for memory is high, although the current high-end server with some of the 2GB standard memory, but most of the use of 1GB standard, we recommend that users buy 2GB memory, if the conditions allow the memory can be upgraded to 4GB. Hard disk, some of the servers are not standard hard drives, the current high-end server mostly support SAS and SATA two specifications of the hard disk, while the motherboard will integrate basic RAID 0, 1, 0+1 disk array features, users can purchase according to their needs of the appropriate hard disk, However, the author suggests that, in the case of economic conditions, try to choose two SAS hard drives to build a RAID 0+1 disk array, first of all, the SAS hard drive has a faster speed, theoretically can reach 6 times times the SCSI hard drive, RAID 0+1 disk array can increase the hard drive data reading speed, Increase the security of your hard disk data.

The above simple to enterprise-class internal application server purchase analysis, the following author for you recommend three price in 20,000 yuan of high-end tower server, for everyone in the purchase of servers to provide certain help.
