[0023] In recent years, with the rapid development of cloud computing, big data, artificial intelligence and other technologies, informatization and intelligence have gradually covered all areas of society. As the core equipment for processing and storing data, the server has higher and higher requirements for its performance, energy efficiency, security and reliability. Therefore, hardware designers will face many challenges.

[0024] Specifically, 1) Improved performance requirements.

[0025] 2) Requirements for energy efficiency and energy saving. Energy consumption in data centers is becoming an increasingly important issue. Server hardware design needs to consider how to reduce energy consumption while improving performance, improve energy efficiency, and achieve the construction of green data centers.

[0026] 3) Server hardware design also needs to deal with space and heat dissipation limitations. Data center space is limited, and the number of servers needs to continue to increase, so it is necessary to design more compact and higher-density server hardware, while solving the server heat dissipation problem to ensure that the server can maintain a stable temperature under high load.

[0027] 4) In terms of security and reliability, as network security threats increase, server hardware design needs to consider how to improve hardware security and prevent hardware from being attacked or tampered with. At the same time, it is necessary to design a hardware system with high reliability and fault tolerance to ensure data security and reliability.

[0028] 5) Flexibility and scalability are also one of the challenges facing current server hardware design. Users' demands for servers are becoming more and more diverse, so server hardware design needs to have certain flexibility and scalability to adapt to different application scenarios and needs.

[0029] At present, the design of server SAS / SATA backplane is mainly based on Figure 1 Take the front window back panel design shown in the figure as an example.

[0058] In this embodiment, for a mainboard having a 12V power interface, a 5V power interface, and a 3.3V power interface at the same time, the 12V power connector of the control board is connected to the 12V power supply of the mainboard through the 12V power interface of the mainboard, the 5V power connector of the control board is connected to the 5V power supply of the mainboard through the 5V power interface of the mainboard, and the 3.3V power connector of the control board is connected to the 3.3V power supply of the mainboard through the 3.3V power interface of the mainboard. Since the 12V power connector, the 5V power connector, and the 3.3V power connector are respectively connected to the male heads of multiple gold fingers through internal wiring, and the male heads of multiple gold fingers are respectively connected to the female heads of multiple gold fingers, the 12V power supply, the 5V power supply, and the 3.3V power supply can reach multiple storage boards through multiple gold fingers, and the storage board can power the hard disk through the hard disk connector.

[0059] In one embodiment, if Figure 3 As shown, the control board 301 also includes: a metal-oxide-semiconductor field effect transistor (MOS tube). The metal-oxide-semiconductor field effect transistor is set on the internal integrated circuit signal link, and is used to isolate the 3.3V power supply of the mainboard end and the backplane end, and has a protective effect.

[0060] Specifically, the MOS tube of the control board 301 is arranged on the internal integrated circuit signal link, which can separate the 3.3V power supply of the mainboard end and the backplane end, and the MOS tube can play a role of level isolation protection.

[0061] In one embodiment, the control board 301 further includes: a temperature sensor. The internal integrated circuit connector is connected to the temperature sensor through internal wiring. The temperature sensor collects temperature data of the backplane and sends the temperature data of the backplane to a baseboard management controller (BMC) chip of the main board 303 through an internal integrated circuit signal link.

[0062] Specifically, the temperature sensor of the control board 301 is connected to the internal integrated circuit connector through internal wiring, and an internal integrated circuit signal link consisting of the internal integrated circuit interface of the main board 303-the internal integrated circuit connector of the control board 301-the temperature sensor of the control board can be formed. The temperature data of the backplane collected by the temperature sensor can be sent to the baseboard management controller chip of the main board 303 through the internal integrated circuit signal link.

[0063] In this embodiment, an internal integrated circuit signal link can be formed, consisting of the internal integrated circuit interface of the mainboard, the internal integrated circuit connector of the control board, and the temperature sensor of the control board. The temperature data of the backplane collected by the temperature sensor can be sent to the baseboard management controller chip of the mainboard through the internal integrated circuit signal link.

[0064] In one embodiment, the storage board further includes: a high-speed signal connector. The high-speed signal connector is connected to the mainboard end through a cable, and the high-speed signal connector is connected to the hard disk connector to form a high-speed signal link between the mainboard and the storage board, so as to perform read and write operations on the hard disk through the high-speed signal link.

[0065] That is, the high-speed signal connector of the control board is transferred to the storage board. The control board only has sideband signals (such as lighting signals and internal integrated circuit signals) and power supply, and no high-speed signal wiring is involved. In this way, the backplane is more modular, the functional attributes of different modules are stronger, and the high-speed wiring distance can be effectively shortened, the high-speed signal wiring distance can be reduced, the high-speed signal quality can be improved, and it can adapt to the SAS5.0 rate requirements.

[0066] In this embodiment, the high-speed signal connector is arranged in the storage board, the high-speed signal connector is connected to the mainboard end through a cable, and the high-speed signal connector is connected to the hard disk connector, so that a high-speed signal link consisting of the mainboard end-the high-speed signal connector of the storage board-the hard disk connector of the storage board can be formed, and the hard disk can be read and written through the high-speed signal link. In this way, the control board no longer involves high-speed signal wiring, reduces the high-speed signal routing distance, improves the high-speed signal quality, and can adapt to the SAS5.0 rate requirements. In addition, the backplane has a higher degree of modularity, and the functional attributes of different modules are stronger.
