Just choose the right ones and don't buy expensive ones: how to choose servers according to demand

At present, there are many kinds of servers, which are divided into processor architectures. Servers include RISC servers and X86 servers. Generally, we refer to general-purpose X86-based servers as PC servers. From applications, servers can be divided into Web servers and mails. Server, database server, etc. Different users have different requirements for the server, and the corresponding server products are required to meet the requirements. Generally speaking, the user needs are mainly as follows:

First, the user needs analysis of the server requirements

1. Space requirements

If the space of the enterprise or government room is limited, in order to save costs, the lower the cost of the server, the lower the cost, so in these users Most of the server procurement adopts 1U and 2U rack server products. With the launch of the blade server, its high density can better meet the needs of such users. For example, in the Internet hosting industry, the user group with the most obvious space requirements is .

2, decentralized configuration user needs

For the education industry, users generally disperse servers, distribute each server to specific schools and unit users, no need for rack servers, generally Use a tower server. Similar decentralized servers and servers are absolutely low-volume users, and the tower server is easy to place to better meet the needs of such users.

3, centralized configuration user needs

In many users, such as the petroleum industry and higher education industry, users need a large number of server products at one time, specifications and configurations are different, and require fast Server maintenance. Therefore, the server is generally required to be matched with the cabinet system for easy management, and the hard disk and the power supply are mostly hot-swapped so that they can be quickly replaced in the event of a failure.

4, specific application user needs

Game server, is actually a high performance file server, storage capacity and I /O performance is a key factor reflecting the quality of the server, many domestic online games The company also chose blades as standard. Such servers need to be equipped with fiber or Gigabit Ethernet interfaces to provide greater network data exchange capabilities. For larger disk capacity, you can choose SAN or NAS as auxiliary devices to form RAID. The system is also the key to improving the performance of the game server.

Video Server, the loaded video stream requires a server with higher accessories. Dual-core or multi-processor technology can greatly improve the server's ability to process media video streams. In the case of limited economic conditions, you can choose a single 2U server, with 1GB memory, 2.5TB SATA hard disk to form RAID 5 mode, improve the server. Storage needs. Under the premise of ensuring the memory capacity, users can purchase higher performance SAS hard disks in the face of multiple I/O commands.

Second, the user's choice of server

From the above analysis, it can be seen that there are many factors affecting the choice of server, users need to comprehensively evaluate the hardware system of the server, but also need to combine The choice of the server can be achieved by its own application and actual situation.

At present, domestic server manufacturers can be roughly divided into domestic and foreign camps. There are IBM, Hewlett-Packard, Dell, SUN and other manufacturers abroad, while domestic ones have waves, Lenovo, Dawning, Founder and so on. In terms of products, foreign companies are mainly concentrated in the middle and high-end, while domestically, they are mainly concentrated in the low-end.

Purchasing server, how to choose a supplier?

1. By way of bidding

Since the current server procurement is realized by intermediate institutions such as “tendering center” or “procurement center”, the supplier qualifications are “checked” through these intermediate institutions. The reviewer's "review" and "selection" can choose a good supplier.

2, through the manufacturers exchange

Whether it is a foreign server or a domestic server manufacturer, they do not directly enter the server procurement price link, but through the supplier to achieve. We communicate well with the sales and technical staff of the server vendors to get a good understanding of the situation, so that when the server is purchased, "there is a lot of heart."

3, through user research

Before the server procurement, investigate the actual situation of the relevant server vendors, focusing on cost performance, product stability, server performance, whether there is hardware expansion and addition Application software functions can really meet the actual application needs of users.

4, through after-sales service

The server hardware system mainly includes: processor, memory, storage system (hard disk), network system (generally integrated with the motherboard), motherboard, chassis, power system, The cooling system and the noise control system are composed of several parts. In addition to the hardware system, the server system also includes the software system part, which differs greatly from the server manufacturer and belongs to the personalized product part.

There is no after-sales product is not a good product, the server as an industrial product, sometimes a small problem can not be avoided, but the problem can not be solved in a timely manner will have a great impact on the enterprise, and even if the product can But customers will not be assured, so after-sales service is also a very important factor, you can choose the server through the investigation, research and comparison of after-sales service. It consists of two parts: first, the traditional after-sales service part. The server manufacturer supports the user in the event of a failure of the server product, such as maintenance, equipment debugging, and equipment replacement. Second, spare parts reserves and technical reserves invested by server manufacturers to ensure server products. This part of the user is difficult to see directly, and can only be reflected indirectly through the first method. The service quality of a server manufacturer is directly related to the strength of the second part of the investment. From the service point of view, there is still a gap between the timeliness of service and the domestic brands in foreign brands, and the service price is higher than the domestic brands.

In short, if the corresponding investigation is not done in the early stage, the user will inevitably have a selection error when selecting the server, and the server will not meet our needs or waste resources. In the server product, the server system is a hard part, it can be seen and seen, and people know more about it. Service is the soft part and the most easily overlooked part. Both parts must be taken into consideration and cannot be “hard and soft”.
