The listing of Inspur Tissot K 1 system has broken the situation that the core equipment of information network is controlled by people, marking the completion of the key layout of China's information construction strategy, which not only fills the gap in the domestic high-end server market, but also greatly reduces the cost of domestic users.
Inspur Tissot K 1 system replaced foreign minicomputers in Xinjiang Branch of China Construction Bank in August, 1965, and it was successfully applied. At the bidding meeting of mainframe held in The Export-Import Bank of China at the end of last year, it beat IBM and HP to win the bid. In the two-year test, Tissot K 1 has achieved stable operation for 840 consecutive days, and there has never been unplanned downtime. Inspur Tissot K 1 system has achieved a key breakthrough in technology. Inspur Tissot K 1 system is based on the classic CC-NUMA architecture designed by ourselves, which can be extended to 32 processors, 256 cores and 4TB of global * * * shared memory at most; The peak floating-point operation ability of the system reaches 2560GFLOPS, which means that 2.56 trillion floating-point operations can be completed every second.
The total memory bandwidth of Inspur Tissot K 1 system is 1 177.6GB/s, the total interconnection bandwidth of the system is 1088GB/s, and the total I/O bandwidth of the system is 675 GB/s. That is to say, if a HD with the size of 15G is transmitted,
Inspur Tissot K 1 system has 1 to 8 hardware partitions, which can be arbitrarily combined to expand 4 to 32 channels and support up to 48 PCIe Gen2 slots. Run with inspur K-UNIX operating system. K-UNIX is the only UNIX operating system in China that meets the UNIX 03 standard. It has achieved compatibility with mainstream databases, middleware and other commercial software, and established a perfect software and hardware ecological environment.
Tissot K 1 also adopts the internationally advanced processor cooperative chipset technology independently developed, with two 25.6GT QPI ports, and the total bandwidth of the processor interface is 51.2 GT/s; /s； 4 8.5Gbps X8 NI ports with total bandwidth of 68 GB/s; The 20-channel data alignment and clock data locking technology of Tissot K 1 realizes the reliability of multi-channel data transmission.
Tissot K 1 adopts parallel non-blocking protocol processing pipeline mechanism based on multi-level classification, which reduces access delay and improves protocol processing throughput. In addition, the system also realizes the multi-clock domain design of the processor cooperative chip to meet the different clock frequency requirements of the chip module. Key application hosts are the main source of profit in the server market. In 20 12 years, the market scale of key application hosts in China has reached152 billion yuan, and it is growing steadily. Among them, the sales volume of key application hosts accounts for 4% of the overall server market, while the sales volume accounts for as much as 42% of the overall market, which shows its importance in the profit of the server market.
Key application hosts are not only the main body of market profits, but also the core of the whole software and hardware industry, which largely determines the flow of industrial profits and gradually becomes the core means for manufacturers to obtain profits. It is not difficult to see that Inspur Tissot K 1 system not only has a broad market prospect, but also consolidates the industry position of China's key application hosts, and will also open up a high-return market space for domestic system integration, system software development and technical service market, which will help to establish China's information industry with independent technology system.
