Server DIY is popular among people for its high cost performance, low energy consumption and flexible configuration. People are increasingly seeing DIY assembled servers running in schools, enterprises, small data centers, game enthusiasts and graphic image design studios. . In fact, DIY server is very suitable for data center, data storage center and virtualized construction of relatively high-end computer room, which can better reflect the cost advantage of DIY server. However, when assembling the server, pay more attention to performance performance and reasonable configuration.
CPU is the heart of
CPU server is the core server and determines the grade of service. The entry-level server generally adopts a single-channel structure, that is, usually only one CPU, and the chassis also adopts a 1U/2U standard telecom chassis, and cooperates with other corresponding configurations to provide reliable, stable, and efficient performance computing services. Server CPU performance difference is quite large, not only depends on the main frequency, but also depends on the technical age, is Pentium-class, dual-core, quad-core, six-core. If the same is the 2.93GHz main frequency processor, the performance difference between the dual core and the quad core is almost doubled.
The popular entry server on the market now generally uses Intel series processors, such as Xeon 3200/3400/3600, etc., which represent dual-core, quad-core, and six-core, of which the quad-core processor is the most secure. The mainstream product is now installed. A low-end server such as the Dell PowerEdge R310, which is well known in online direct sales, is a 1U rack server with a Xeon 3400 processor. The processor uses a 45nm quad-core process, 8MB L3 cache, clocked at 2.8GHz, and the adoption of a new generation of Xeon processor platforms ensures stable performance and low power consumption.
board is to protect the server's performance
servers, motherboards and various accessories mainly to see the grade. The motherboard has Intel original server motherboards and server motherboards provided by major motherboard manufacturers. In fact, the brand server uses motherboards of motherboard manufacturers, such as ASUS, Gigabyte, etc., but if you want to assemble the server yourself, you can save a lot of money. It is best to spend a few hundred dollars on the motherboard, choose Intel original board. As well.
Intel original motherboard is generally more reliable quality, reasonable configuration, give full play to the efficiency of the CPU, but will not bring fancy design and reliable performance impact. In addition, the original motherboard generally has more functions, and the materials are more sophisticated, because it is to be used by direct customers, so the quality will be more tolerant than various OEM motherboards. Intel single-channel server motherboards mainly include Intel S3420GPRX, S3420GPLX, S3420GPLC, S3420GPV and other models. These motherboards generally support Xeon quad-core, Core i3 and other processors. Generally, there are six DDR3 high-speed memory slots with a maximum capacity of 32GB. , enough for general server use. In terms of storage, there are 4-6 SATA/SAS dual interfaces, hot swappable and 0/1/5/10 RAID functions, and supports GB to TB high-capacity hard drives. Generally, there are dual Gigabit onboard network cards, which are convenient for users.
Price and configuration are people's concerns. Take the entry-level server with a current price of around 5,000 yuan as an example. You can configure the SuperMicro chassis to get good power supply and expansion space. A Xeon 3400 processor for high performance and low power balance, Intel original motherboard is essential, is a stable system platform, in addition to 4GB memory and more than 250GB hard drive, and has a large upgrade space .
In addition, how to assemble server is also a problem. Many users like to find more professional server assembly companies to help them do their own work. In fact, this kind of idea is undoubtedly more reliable. After all, people are long-term battlefields. Now, in the computer market, there are gradually a number of specialized servers. Business IT company. For example, Baotong Technology is a nationwide server hardware and service provider. It provides direct supply to Intel series server accessories through 50 branches and many partners, and provides assembly, upgrade, maintenance and migration services.
