[0027] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

The terms "mount", "connected", "connected" should be understood broadly, for example, it can be fixedly connected, or detachably connected, or integrally connected; it can be mechanically connected, or electrically connected; it can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements inside. The terms "parallel", "perpendicular", "equal" include the described case and the approximate case of the described case, and the approximate case is within an acceptable deviation range, wherein the acceptable deviation range is determined by a person of ordinary skill in the art considering the measurement being discussed and the error related to the measurement of a specific quantity (i.e., the limitation of the measurement system). For example, "parallel" includes absolute parallel and approximate parallel, wherein the acceptable deviation range of approximate parallel can be, for example, within 5°; "perpendicular" includes absolute perpendicular and approximate perpendicular, wherein the acceptable deviation range of approximate perpendicular can also be, for example, within 5°.

The terms "first", "second" and the like in the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence.

[0030] In the standard 2U (88.9mm height) server architecture, due to the limitation of the height of the chassis space 2U, the common mid-backplane layout scheme cannot meet the increasing performance of the processor CPU, that is, the heat dissipation problem of high-power components in the server gradually appears and needs to be solved. In the high-power scenario, although the interconnection scheme of the mid-backplane arranges the expansion interface in the middle of the chassis, although it is convenient for cable management, the axial flow fan is difficult to form an efficient heat dissipation channel in the limited area, resulting in the heat dissipation airflow being blocked by the mid-backplane and the expansion interface, that is, the cable, resulting in local heat conduction effect. Therefore, when the processor power exceeds 250 watts, the temperature of the mid-backplane area for the interconnection of storage products will gradually increase, and therefore, there is an urgent need for a storage product interconnection device that can efficiently and stably transmit signals and has good heat dissipation effect. For this purpose, the present application proposes the following inventive concept:

[0031] By setting parallel customized backplanes, combining customized interconnection cables, and matching hard disk connectors and controller connectors, the interconnection of storage products is realized. Such a setting eliminates the blocking of the backplane body to the heat dissipation airflow, and ensures the stability, efficiency and accuracy of data transmission, while improving the heat dissipation efficiency.

[0032] In order for those skilled in the art to better understand the present application, the present application will be further described in detail below in conjunction with the drawings and specific embodiments.

[0037] In this embodiment, the number of backplane frames 1 can be two, the two backplane frames 1 are arranged in parallel to each other, and the spacing between the two backplane frames 1 is less than the vertical space height 2U of the case. The two backplane frames 1 and the middle hollow area between the two backplane frames 1 for the heat dissipation airflow to pass through together form a heat dissipation structure. In this embodiment, the interconnection cable group can be attached to the surface of the backplane frame 1 in the form of wiring, for connecting the hard disk connector 3 and the controller connector 4 on the backplane frame 1.

[0038] In an optional embodiment of the present application, the backplane frame 1 is a printed circuit board with internal signal transmission lines. The backplane frame 1 uses the internal wiring of the printed circuit board to realize the transmission of electrical signals and data, so that the backplane frame 1 uses the internal wiring of the printed circuit board to efficiently and stably complete the data communication and interconnection task between the controller, the backplane frame 1 and the hard disk, and ensures the accuracy, stability, efficiency and timeliness of data transmission.

The hard disk connector 3 and the hard disk are connected through plugging, and the hard disk is connected with the circuit in the backplane frame 1 through the hard disk connector 3, thereby realizing the interconnection of electrical signals or data. Figure 2 As shown in the figure, the number of hard disks is six. The specific number of hard disks can be configured according to the storage capacity of the storage product.

[0046] The controller connector 4 is installed on the backplane frame 1, and the controller connector 4 is connected with the controller. The controller connectors 4 on each backplane frame 1 realize data transmission through the third interconnection cable 23.

[0047] In this embodiment, the controller connector 4 can be a high-density connector, which has a compact layout and stable and efficient transmission performance, and is a key component to ensure the stable operation of the server. The controller connector 4 can be fixedly installed on the backplane frame 1 in a bolted, welded or bonded manner. The controller connector 4 can realize data connection with the controller through plugging.

[0048] In summary, the interconnection device for the storage product provided by the embodiment of the present application provides a middle hollow heat dissipation structure formed between the parallel backplane frames 1 to provide a heat dissipation channel for the heat dissipation airflow generated by the axial flow fan, improve the space for the heat dissipation airflow to flow, and improve the heat dissipation performance. And the hard disk and the controller are connected through the hard disk connector 3 and the controller connector 4 and the interconnection cable group 2 to realize the interconnection communication between the hard disk and the controller, solve the problem that the high-efficiency signal transmission of the storage product cannot be considered with the heat dissipation effect, and achieve the technical effects of significantly improving the airflow passing efficiency inside the case and improving the heat dissipation performance while ensuring the system reliability.

By increasing the number of the hard disks, the user can easily improve the capacity of the storage system to meet the growing demand for data storage.
