We are customer-centric and provide customized or one-stop full-stack solutions to empower all industries.
The search engine development engineer said about the large-scale search engine backend transformation project that user experience is what the enterprise pursues forever. With the rapid growth of the number of Chinese netizens and the climax of Internet search applications brought by the Olympics, we hope to be ahead of the entire industry, further improve the user search response speed, expand service capabilities, and significantly reduce energy consumption. A series of research and development, optimization and testing completed in two years. 100% flash memory is achieved on the server of the web search service, and the entire system is guaranteed to have excellent stable, safe and reliable commercial performance, bringing users a faster and more stable world-class network experience.
In this search engine backend transformation project, PowerLeader PR2024GN-SSD solid state drive server is used. As China’s first solid state drive server, PowerLeader PR2024GN-SSD deserves to be the star of today. PowerLeader PR2024GN-SSD belongs to PowerLeader G series storage server, which is my country’s first brand SSD solid state drive server. In 2U space, it provides up to 24 SAS/SATA hot-swappable hard disk slots, which can be installed with both HDD disk hard disk and SSD solid state drive, providing a maximum of 96TB data space to meet the high requirements of various large-capacity data storage, transmission, high bandwidth and I/O processing capabilities. SSD solid state drives have many characteristics, such as stronger seismic performance. In the test, they can withstand 3.5G gravity impact, which is unimaginable for traditional hard disks. At the same time, the average failure-free time reaches 2 million hours. Because of this feature, it is deeply loved by users in various industries. Another feature is that SSD solid state drives have fast read and write speeds, with an average read and write speed of more than 170MB/s, and some products even reach more than 250MB/s, so they are very attractive to search engine users. SSD solid state drives are energy-saving, quiet, and reduce space. SSD hard drives are one-fourth more energy-efficient than HDD hard drives, with zero noise. Each hard drive is about the same size as a laptop hard drive, weighing only about 70-80 grams. This technological reform will enable Baidu’s single server device to increase its internal read and write performance by 100 times, its response speed by 3 times, and its overall performance by 1 time, while its energy consumption is much lower than that of ordinary hard drive storage.
Search engines are one of the most used network services. Search engines are very valuable for network marketing, especially for users to discover new websites. Search engines are the first website promotion tool. At present, there are many excellent Chinese information retrieval and delivery technology suppliers in China. Among all portal websites that provide search engines in China, more than 80% have search engine technology support. The current search engine websites include Sina, Tencent, 263, 21cn, Shanghai Hotline, Guangzhou Window, Xinhuanet, Northern Space, Western Space, Chongqing Hotline, Jilin Information Port, Daqing Information Port, Oriental Hotline, Hunan Information Port, Nanyang Information Port, Shunde Information Network, etc. For many years, many search engine operators have received hundreds of millions of search requests from all over the world 24 hours a day with their unique “hyperlink analysis” technology and search speed of seconds. In mid-2018, with the continuous growth of user scale, the search engine industry entered another round of system expansion period, and it was urgent to purchase a large number of server equipment to upgrade the system. In order to meet people’s hope to get results in a dozen seconds, or at most 30 seconds, the expected value is 1 to 2 seconds. That is to say, with a “click” of the mouse, the page on the display screen has changed, and the titles of the first dozen or twenty pieces of information have appeared in front of you.
The PowerLeader Xeon PR2024GN-SSD server is used in this project. Its unique 2U design meets the requirements of various network and information operators and is fully capable of applications that require rapid processing of massive amounts of information. Combined with a customizable and highly scalable scheduling algorithm, the search engine can collect the maximum amount of Internet information in a very short time.
PR2024GN-SSD storage systems equipped with enterprise-class SSD hard drives can provide millisecond application response times, which is 10 times faster than traditional 15000RPM Fibre Channel hard drives. It has achieved 100% flash memory on servers that undertake web search services.
Compared with traditional hard disks, the equipped SSD hard disk increases the internal read and write performance of a single server device by 100 times.
