(The third phase of the international trade center is 330 meters high and has 80 floors. The total investment of the third phase of the international trade center is about 800million US dollars. The main project was completed in 2008. As the tallest building in Beijing, international trade phase III, as one of the landmark buildings in Beijing, will show the international and modern image of the capital to the world, and form a building complex with a total area of 1.1 million square meters with international trade phase I and phase II, becoming the world's largest international Trade Center. The international trade phase III is located in the core area of CBD. In addition to super five-star hotels, high-end office buildings, international boutique shopping malls, cinemas and other facilities, the project also includes a grand banquet hall of tens of thousands of square meters, which will be the largest banquet hall in Beijing.?? As the city label of Beijing, in order to create a safe, harmonious and modern external image, the international trade phase III launched the closed-circuit television digital video monitoring project, which covers all aspects of buildings such as hotels, offices and shopping malls. 1. To meet the storage concurrent large flow, the whole monitoring system has thousands of cameras, and the maximum concurrent large flow of 5150mb/s will appear (the hotel concurrent flow is 2513.3mb/s, and the property concurrent flow is 2636.9mb/s). Such concurrent large flow can be simply and reasonably solved only under the FC-SAN network storage architecture. The single channel data exchange bandwidth of FC-SAN network storage architecture is 4000mb/s. 2. It is easy to deal with the late system upgrade. The complexity of monitoring the actual situation makes the ingested code stream a dynamic value. The number of monitoring channels and control servers increases, and the storage time of monitoring content lengthens. These possible problems can be easily handled in the FC-SAN network storage architecture. 3. Large capacity and low cost requirements the total budgeted capacity is 230tb (RAID5 capacity). Huge storage requirements and low cost are a contradiction. In the FC-SAN network storage architecture, the whole system adopts the expandable eonstora24f-g2430 disk array and the high-performance hard disk with a single disk of 1TB, so that the whole storage cost is controlled to the lowest. Considering the above factors, the unique features of FC-SAN network storage architecture, such as stability, high performance, convenient expansion, centralized storage and unified management, make it the best choice for the storage subsystem of the project.)
