Set up efficient mail server rack-type server comparison shopping guide

E-Mail is one of the most popular applications on the Internet. Like a postman distributing traditional mail, e-mail is asynchronous, meaning that people send and read emails at their convenience, without having to collaborate with others beforehand. Unlike traditional messages, e-mail is fast, easy to distribute, and inexpensive. In addition, modern e-mail messages can contain hyperlinks, HTML-formatted text, images, sounds, and even video data. The main performance parameters of the

Here are a few of the major factors that we consider affecting the overall performance of the mail server.

1, the impact of server configuration levels. The server's configuration level is one of the main factors that affect the performance of the mail server, including processor performance, memory capacity, SCSI or IDE transfer rate and disk read/write speed, network adapter maximum throughput, and so on, so that the server's configuration is at a higher level. Of course, if dynamic load balancing technology is adopted, the hardware configuration of the mail server can be extended to meet the changing business needs.

2, the impact of network bandwidth. The bandwidth of the network determines the level of network communication. In the advent of the broadband era, but also to solve the problem of the bandwidth of the mail server, for the network load larger users still need to send the support of telecom service providers.

3, the impact of the operating system. Currently the more popular operating system is UNIX, Linux and Windows systems, these systems are different, the different operating systems in the processing mechanism is often likely to cause the performance of the mail server system differences.

4, the impact of message design technology. Whether to use LDAP protocol or database method for user login authentication and management, and whether to use TLS to encrypt processing, provide anti-virus module, virus processing mechanism and so on, are the main factors that affect server system performance. We should find the best point for the performance of the mail server on the basis of ensuring the product function, security and stability.

5, the impact of user configuration levels. Because most of the mail server parameters can be adjusted, therefore, the user operators also have higher requirements, the level of user configuration is also an important factor affecting the use of mail servers.

Dell PowerEdge 2950

The Dell PowerEdge 2950 Server, based on the Intel Core, employs a dual-slot 2U rack structure that ensures the best combination of internal scalability and rack density, which reduces space and energy requirements while providing the best server performance for the enterprise. Can support almost all types of enterprise applications, including databases, email, and network infrastructure.

The Dell PowerEdge 2950 Server employs a 2U rack structure, with 1 45 nm quad-core Xeon5410 processors, a core frequency of 2.33GHz, a two-level cache for 2*6MB, a front-end bus 1333MHz, and a maximum of 2 CPUs. Equipped with 2 2GB ECC DDR2 full buffer memory, maximum support memory capacity 32GB ECC DDR2 full buffer memory, ECC technology can effectively reduce the memory address errors resulting from the system more stable.

The storage is configured with 3 high-speed 146GB SAS hard drives, with the RAID-5 mode, providing 6 SAS disk bits and maximum support for 1.8TB SAS drives. Dual built-in Broadcom Pro Gigabit NIC Adaptive network card, 3 expansion slots, with hot-swappable redundant cooling fan, optional hot plug redundant power supply 1, power 750W. DVD drives are also available.

The Dell PowerEdge 2950 Server uses energy-saving components and provides optional onboard real-time power monitoring capabilities that help reduce unnecessary energy consumption. Internal components allow physical and logical locking to prevent unauthorized access. Dell's PowerEdge 2950 is a good performance in the areas of enterprise database building, email applications, and Web applications.
