Things to note when purchasing mid-range quad-core servers

The rapid development of information technology has led to the rapid development of the entire information industry. More and more e-commerce and ERP management applications in enterprises are the products of the rapid development of information technology. The server is the most important information release platform in the entire informatization process, and its performance largely determines the process of enterprise informatization.

1. Processor performance

The processor is the core of a computer. For a server, it is responsible for the core computing of the entire server. Its performance directly determines the performance of the server. At present, in terms of server processors, there are three main manufacturers: IBM, AMD and Intel. IBM's Power series processors are basically not used in ordinary servers. The most common ones are Intel's Xeon and AMD's Opteron series processors. These two series of processors are divided into single-channel, dual-channel and four-channel. In addition, they are also divided into single-core, dual-core and quad-core according to the number of cores. For enterprise applications, dual-channel quad-core is currently the most widely used. .

2. Memory capacity

The memory capacity determines the performance of the entire server to a certain extent. If the memory capacity is too small, it will cause a bottleneck in the system. First, it cannot meet the performance requirements of the application. Second, it cannot give full play to the overall performance of the server. Some servers Resources are wasted. At present, most mainstream quad-core servers use 1GB as standard configuration, and some servers have 2GB or more as standard configuration. For ordinary quad-core servers, at least 2GB of memory capacity is required to fully exert the server performance. Users can use all the To meet the needs of deploying applications, increase the memory capacity appropriately. Currently, most quad-core servers support more than 16GB of memory capacity.

3. Storage capacity

The storage capacity referred to here is actually the hard drive capacity. For mid-range quad-core servers, some servers are equipped with hard drives, while some are not provided with hard drives as standard. These servers generally use SAS interfaces, so they can support SAS. There are two kinds of hard disks, SATA hard disks. These two hard disks are very different. In terms of reading speed, SAS hard disks have an absolute advantage, while SATA hard disks have a greater advantage in terms of price and single hard disk capacity. It also has great advantages. At present, the largest single SATA hard drive has a capacity of 1TB, while a SAS hard drive is only 300GB. Therefore, users who need larger capacity are best to choose a server that supports SATA hard drives, and those with high read requirements For speed users, it is better to choose a SAS hard drive with better performance.

4. Manageability

The management performance of the server is another important factor. Quad-core servers generally provide good management performance. Users can manage the server remotely, and it is very user-friendly.

5. Scalability

Scalability is also a very important factor. Whether a server has good scalability directly determines its life cycle. Users' performance requirements for servers are constantly increasing. When the demand increases to the limit that the server can bear, whether it can It is critical for the server to continue to meet the needs of users through upgrading. If it cannot be upgraded, the user can only purchase a new server, which will not only increase the additional cost, but also need to transfer data, etc., which will be very troublesome. question.

Generally speaking, it is enough for a mid-range quad-core server to have the above five points, but users also need to pay attention to some details when purchasing, such as whether the power supply can meet the needs of the server, whether the heat dissipation is good enough, etc. Below, the author recommends four mid-range quad-core servers to give you some help when purchasing.
