The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
The terms "comprises," "comprising," and "having," and any variations thereof, in the description and claims of the present invention, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
As shown in fig. 1, an embodiment of the present invention provides a novel frame-type hardware system platform and device based on orthogonal architecture, which includes a high-speed backplane provided with orthogonal connectors, sixteen service processing boards, four switch boards, and two main control boards.
The service processing board is horizontally arranged, the exchange board is vertically arranged, the main control board is horizontally arranged on the high-speed back board, and the exchange board, the service processing board and the main control board form a vertical orthogonal relation on a overlooking projection plane. The data path exists between sixteen service processing boards and four exchange boards, the control path exists between two main control boards and sixteen service processing boards and four exchange boards, and the control path exists between two main control boards and sixteen service processing boards and four exchange boards. The data path, the control path and the management path among the board cards adopt different protocols, and the three are mutually separated.
As shown in fig. 2, a data path exists between sixteen service processing boards and four switching boards, and is used for data exchange with a large capacity. The data exchange capacity of each service processing board is 1.6T, and the service processing boards are divided into 4 orthogonal connectors which are connected to 4 exchange boards. The data exchange capacity of each exchange board is 6.4T, and the exchange board is divided into 16 orthogonal connectors connected to 16 service processing boards. The switching capacity from each service processing board to each switching board is 400G, and is composed of 4 100G in implementation. In order to adapt to different application occasions, each 100G of the exchange board can be used by reducing the speed to 40G.
As shown in fig. 3, the control path exists between two main control boards and sixteen service processing boards and four switching boards, and is used for transmitting the control protocol between the boards, so as to implement real-time control of the main control boards on the service boards and the switching boards. The two main control boards are in a main-standby relationship with each other. When the main card breaks down, the control path of the system can be automatically switched to the slave card, and continuous fault-free stable operation of the equipment is realized. Compared with the traditional 1G Ethernet realization mode, the control channel of the main control board, the service processing board and the exchange board adopts 10G Ethernet, and can meet the high bandwidth requirements of various current complex control protocols.
As shown in fig. 4, a control path exists between two main control boards and sixteen service processing boards and four switching boards, and is used for transmitting a management protocol between boards, so as to implement real-time management of the main control boards on the service boards and the switching boards, including reading and controlling power states and temperature states of the boards. The two main control boards are in a main-standby relationship with each other. When the main card breaks down, the control path of the system can be automatically switched to the slave card, and continuous fault-free stable operation of the equipment is realized. The control path of the main control board, the service processing board and the exchange board adopts a point-to-point I2C protocol. The I2C protocol only needs to use 2 lines, when the number of the service cards is increased by 1 block, each main control card only needs to increase 2 lines, and a compact low-speed connector is adopted, so that the limitation of the load number of the traditional bus type IPMB is overcome. The I2C protocol of the main control card is realized by a CPLD chip with programmable hardware, and can be compatible with the proprietary protocols of part manufacturers.
