In summary, according to the modularized high-density distributed server, the ARM service board 2 and the small switch board 3 form the distributed server, the processing capacity is strong, each ARM system operates independently and can communicate with each other, the PCIE golden finger has a high acquisition speed, the acquired data is transmitted to the bottom board 6 through the PCIE golden finger for data processing, and the modularized high-density distributed server has the characteristics of high-speed acquisition and transmission, the ARM service board 2 can be vertically plugged and pulled out for replacement and upgrade, the stability and the capacity expansion of an interface are improved, the height of the case 1 does not need to be increased, the space of the cabinet is better utilized, the distributed whole system is built by respectively using the ARM main chip, the processing and computing capacity of the core can reach the X86 level, the instruction execution speed of the ARM main chip is higher, the addressing mode is flexible and simple, the execution efficiency is high, the instruction length is fixed, the ARM service board 2 can be rapidly developed along with the upgrade of the ARM chip, the processing of the whole system is improved, The power adapter 9 adopts a 1+1 redundancy design, the reliability of the system is improved through multiple backup, when the system fails, the fault time of the system is reduced, the output of the shift latch 13 is controlled through serial signals, the power of the ARM business board 2 and the power of the small exchange board 3 are controlled, the corresponding ARM system can be opened or closed according to business requirements, the electric loss is reduced, the service life of a machine is prolonged, the machine case 1 can be pulled out of the machine cabinet through the guide rail 11, all modules are plugged in and out, the space of the machine cabinet is effectively utilized, the process is more exquisite, and the volume is smaller.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be able to cover the technical solutions and the inventive concepts of the present invention within the technical scope of the present invention.
