[0002] The hard disk backplane, also known as the hard disk drive backplane, is a part of computer hardware. Its main function is to connect and manage multiple hard disk drives. The hard disk backplane is usually installed on the hard disk rack of a computer or server and has multiple hard disk interfaces, such as SATA, SAS, and even PCIe NVMe. It connects multiple hard disks to the motherboard through these interfaces, and can effectively transfer and manage the data of multiple hard disks between motherboards. With the advent of the big data era, frequent data transmission requires the hard disk backplane to have a higher transmission rate and more stable transmission performance. Under the current market conditions, the existing hard disk backplanes usually only support one or two of SAS / SATA or NVME, and do not have broad compatibility. In addition, the hard disk backplanes on the market are mostly 4-disk and 8-disk backplanes. The 12-disk panel is generally composed of two backplanes of 4+8 disks. During the disassembly and assembly process, the backplane needs to be removed twice, which is very inconvenient. Utility Model Content

[0022] The overall idea of ​​the technical solution provided by the utility model is as follows:

[0023] See also Figures 1 to 5 , a hard disk backplane, comprising:

[0024] A circuit board 100, wherein the front side of the circuit board 100 is integrated with 12 first connectors 200 and an LED indicator light 300 arranged next to the first connectors 200, wherein the first connectors 200 are used to connect a PCI E NVME interface, a SAS interface and a SATA interface.

[0025] Preferably, the first connector 200 is an SFF-8639 high-speed connector. SFF-8639 is a high-speed hard disk connector specification, and its full name is Small Form Factor-8639. Since it provides a variety of connection methods, the flexibility of using the hard disk is greatly improved. The SFF-8639 high-speed connector can support SATA, SAS and PCIe NVMe interfaces at the same time, and can support higher data transmission speeds, even up to 32Gbps, and is therefore widely used in enterprise-level storage systems and high-performance personal computers.

[0026] The back of the circuit board 100 is integrated with a second connector 400, a third connector 500 and a power connector 600. The second connector 400 is used to transmit PCI E high-speed signals, the third connector 500 is used to transmit SAS / SATA high-speed signals, and the power connector 600 is used to connect a power source and provide power to the circuit board 100.

[0027] Preferably, the second connector 400 is an MCIO high-speed connector. MCIO (Multimedia Content Input / Output) is a high-bandwidth, high-performance connector designed for processing and transmitting large amounts of multimedia content. The high speed and high bandwidth characteristics of the MCIO high-speed connector can make the hard disk backplane more efficient in processing large data and high-intensity computing, providing a strong guarantee for the performance of the hard disk backplane.

[0028] Preferably, the third connector 500 is an SFF-8643 connector. SFF-8643 (Serial Attached SCS I) can provide fast and stable data transmission efficiency, meeting the peak demand for storage device read and write speeds in the big data era.

[0029] Furthermore, there are 6 second connectors 400 and 3 third connectors 500. By providing 6 second connectors 400 and 3 third connectors 500, users can flexibly choose to connect more hardware devices, which makes the application scenarios of the hard disk backplane more abundant and can also meet the various needs of different users.

[0030] The first connector 200, the second connector 400, the third connector 500, the LED indicator light 300 and the power connector 600 are connected by metal wiring. The metal wiring is used to transmit data and power.

[0031] The embodiment of the utility model sets 12 first connectors 200 on the front of the circuit board 100 for connecting the PCIE NVME interface, SAS interface and SATA interface, and only one backplane is used to support 12 disks, which is more convenient for disassembly and assembly. In addition, the design sets an LED indicator 300 next to each first connector 200 to display the connection status of the corresponding first connector 200. The second connector 400 and the third connector 500 are arranged on the back of the circuit board 100 for transmitting PCI E high-speed signals and SAS / SATA high-speed signals. The circuit board 100 also has a power connector 600 for access to power supply. The design greatly improves the compatibility of the hard disk backplane.

[0032] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] See also Figure 4, the circuit board 100 is also provided with a CPLD logic chip 700, and the CPLD logic chip 700 is connected to the LED indicator light 300 and the power connector 600. The introduction of the CPLD logic chip 700 can control the state of the LED indicator light 300, and can control the lighting and extinguishing of the LED indicator light 300 according to the actual situation, so that the user can more intuitively understand the connection state of the first connector 200. For example, when the first connector 200 is connected to the NVME disk, the CPLD logic chip 700 controls the LED indicator light 300 corresponding to the first connector 200 by receiving and decoding the hot-swap I2C signal of the motherboard. When the first connector 200 is connected to the SAS / SATA disk, the CPLD logic chip 700 controls the LED indicator light 300 corresponding to the first connector 200 by receiving and decoding the SGPIO signal of the motherboard / RAID card, so as to achieve the purpose of management. At the same time, the CPLD logic chip 700 is also connected to the power connector 600, and the power connector 600 is used to supply power to the CPLD logic chip 700.

[0034] See also Figure 5 , the power connector 600 is connected to the DC-DC power adapter chip 800, and the DC-DC power adapter chip 800 is used to convert voltage. Specifically, the DC-DC power adapter chip 800 is used to convert the voltage delivered by the power connector 600 according to the actual working voltage requirement of the circuit board 100, so as to ensure that each component on the circuit board 100 can operate normally at a voltage suitable for its own operation, thereby improving the energy efficiency and equipment stability of the hard disk backplane.

[0035] Furthermore, a temperature sensor is provided on the circuit board 100, and the temperature sensor is used for board end temperature monitoring. Specifically, the temperature sensor is designed to continuously monitor the operating temperature of the hard disk backplane. If the operating temperature exceeds the designed safety range, the temperature sensor will initiate a pre-set emergency measure, such as warning the user, reducing the workload of the hard disk, or automatically shutting down the hard disk to prevent possible overheating damage.
