Starting from "core": Guide to purchasing Internet cafe servers

Because an internet cafe server is the heart of an Internet cafe, If you first consider the price when purchasing servers, maybe you need to understand the development of internet cafe servers at this time. The mainstream configurations of servers are as follows:

CPU: (mainstream)

XEON clock speed: 3.0G

External frequency: 800 M

Cache: 2 MB

Glossary:

Cache refers to a memory that can exchange high-speed data. It first exchanges data with the memory and CPU. Therefore, the cache speed increases rapidly because the cache commands and data work in the same frequency as the CPU, the more information is stored, the data exchange between CPU and memory can be reduced, and the computing efficiency of CPU can be improved.

(Tip 1: select a server and check the CPU clock speed first. Currently, the main clock speed of the CPU is GB or above. There are still some servers on the market that use XEON2.0G, which was two years ago, let's look at the external frequency. Currently, the latest external frequency is 800 M, and the XEON2.0G has a maximum external frequency of 533 M. Then, the higher the cache, the faster the CPU operation speed, this is what everyone knows)

Memory: (mainstream)

Category: DDR Ⅱ REG ECC

Size: 2 GB

Efficiency: 400 M

Chip: infineon, Samsung

Glossary:

What is DDR2? DDR2 is the abbreviation of "doubie datarate", while DDR2 is the second-generation solution of this memory technology. Why is DDR2 faster than DDR1? This is mainly because the chip uses new technologies and features to improve the integration of data signals, so that the ability to operate at a faster clock speed.

These technologies include "ON-Die Termination" and "OFF-Chip Driver Calibration". Of course there are many other new technologies, such as DDR2 with a larger 4-bit prefetch, enhanced registers also increase the latency. ON-Die Termination or ODT means that Mount Termination Register (mounted terminal Transistor) has been transferred from the motherboard itself to the DRAM chip.

In this way, the signal integrity can be improved by controlling the reflected noise in the transmission path. In addition, the system design is simpler because the terminal transistor placement and wiring are better handled.

(Tip 2: When selecting a server, do not be confused by the memory size. Currently, most of the server's memory is DDR2, And the DDR1 era has passed. The benefits of DDR2 are already known to everyone, so when you select a server, you need to ask the proxy, is the memory DDR2? Whether the chip is the best chip in memory, such as infineon, Samsung, and miscellaneous chips can easily cause server crashes)

CCC:

Glossary:

In accordance with China's commitment to join the WTO and the principle of national treatment, the State uses a uniform logo for mandatory product certification. The name of the new national mandatory Certification mark is "China mandatory Certification". Its English name is "China Compulsory Certification" and Its abbreviation is "CCC ". After the implementation of China's mandatory certification mark, it will gradually replace the originally implemented "Great Wall" Mark and "CCIB" mark. The CCC product must be used as follows:

Information technology equipment: microcomputer, portable computer, display device used with computer, built-in power and power adapter with computer, charger, computer game machine, learning machine, photocopier, server, financial and trade settlement electronic device.

You can see that the server belongs to the CCC product. The server that passes the CCC is a regular server with quality assurance. If you use a server that does not pass the CCC certification in your Internet cafe, not only is the operation of your Internet cafe not guaranteed, but according to relevant regulations, you will be investigated and punished by the relevant departments. According to our understanding, in the past three years, many Internet cafe owners have been punished for failing to purchase servers and workstations that pass CCC.

(Tip 3: When purchasing an internet cafe server, please identify the server with CCC certification to ensure your own rights and interests !)

This Guide only provides three tips, which are also the most confusing part. Some people may ask, there is no need to buy a brand for my Internet cafe servers, and there is no need to buy expensive ones. That's enough!

Indeed, if someone will recommend a server with a lower price when purchasing a server in your Internet cafe, you should pay attention to the CPU and memory of the server and whether the server passes CCC, if this server has reached the above points, I believe you can buy it immediately, because at this time you will make money! You have bought a server worth the money! Generally, this low-cost and beautiful Server is a joint activity between server manufacturers and large enterprises such as INTEL. At this time, when you buy a server, it will be rolled over!

Finally, when buying servers, you must check the brand to see if the brand has a strong brand. When it comes to warranty, everyone can promise a three-year warranty, you have also purchased other products with a three-year warranty. In the end, only powerful brands can achieve this. Therefore, the short commitment is not enough, when purchasing servers, you must check the growth of this brand, whether there are professional rendering materials, professional packaging, professional repair processes, and so on.

Therefore, you must check the mainstream core when purchasing the server.

1. Server master chip: Currently the mainstream is INTEL 7320,7520 (XEON predecessor is 7201 and later is 7500) P4 is INTEL7230 (P4 predecessor is 7221 and later is 7210)

2. CPU chip: The current mainstream is XEON3.0G/2 M/800 M (predecessor: 2.8G and then the first 2.4G/1 M/533M and then the first 2.0G/512 K/533 M/400 M)

3. memory chip: DDR2/2G/reg ecc/400 M (formerly DDR1 333/266 M 1G/512 M)

The heart is the most important place for people, and the core is also the most important place for servers, as long as the server core is good! Your Internet cafe is good!
