Description

Technical Field

[0001] The utility model relates to the technical field of hard disk testing equipment, in particular to a multi-interface U.2 SATA aging board. Background Art

[0002] With the rapid development of information technology, enterprise solid-state drives (ESSDs), as core components of data storage, play a vital role in data centers, servers, the internet, cloud services, intelligent manufacturing, and high-performance computing. These SSDs must not only maintain extremely high data integrity and security, but also meet the demands of long-term, high-intensity read and write operations, ensuring stable operation in a variety of application scenarios.

[0003] Enterprise-class SSDs offer significant features, including but not limited to: strict requirements for data integrity and security, safeguarded by features like data encryption; extended write lifespans to handle the long-term, high-frequency data read and write operations of enterprises; high, stable, and balanced continuous I / O performance to ensure efficient data exchange; support for heavy write workloads and extreme environmental conditions, and built-in protection against power outages, further enhancing data reliability and security. Furthermore, enterprise-class SSDs generally have larger capacities, typically starting at 4TB (3.84GB), with some products boasting a maximum single-disk capacity exceeding 32TB, meeting the demands of large-scale data storage.

[0004] However, enterprise-grade SSDs differ significantly from standard consumer-grade SSDs in terms of power consumption and power supply requirements. Due to their large capacity and high performance, enterprise-grade SSDs consume relatively high power, placing extremely high demands on the power supply system. Therefore, these drives typically utilize a dual-voltage power supply of DC5V and DC12V. Ultra-large capacity models must utilize a DC12V power supply to ensure stable operation.

[0005] During the production and testing of enterprise-class solid-state drives (SSDs), burn-in testing is a crucial step in ensuring product quality and reliability. Traditional testing methods typically use a card adapter to insert a U.2 (SFF-8639) enterprise SSD into the motherboard's PCIe expansion slot for testing. While this testing method ensures test robustness and signal integrity to a certain extent, it still has several drawbacks:

[0006] Low test efficiency: Due to the limited power supply capacity of the PCIe expansion slot, large-capacity enterprise-class solid-state drives can only be tested individually, and multiple drives cannot be tested simultaneously, thus reducing test efficiency.

[0007] Vibration problem: Traditional testing methods lack the necessary reinforcement measures. During long, high-intensity testing, the hard drive may suffer from poor contact or test interruption due to vibration, thereby affecting the accuracy and yield of the test. Utility Model Content

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0027] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technical personnel in this field without creative work are within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the creation of the present invention can be combined interactively without conflicting with each other.

[0028] like Figure 1-2 As shown, the present application provides a multi-interface U.2 SATA aging board, including a circuit board 1 as the main body of the aging board, on which a horizontal U.2 female connector 2, a DC12V power interface terminal 3, a step-down circuit 4 and a reinforcement device 5 are provided, wherein:

[0029] The circuit board 1 has a thickness of 1.6 mm to match the thickness requirement of the PCIE expansion slot connector; it adopts a PCIEX16 164P interface and a full-PIN gold finger interface, which is more stable than PCIE X2 or PCIE X4.

[0030] Since the number of power interfaces of PCIE X16 164P is limited and the cross-section cannot support ultra-high power supply requirements, this application only powers the PCIE to SATA bridge control chip and peripheral circuits.

[0031] The input end of the DC12V power interface terminal 3 is connected to the DC12V power supply interface of the computer, and the output end is connected to the step-down circuit 4, which converts the DC12V voltage provided by the computer into a DC5V voltage.

[0032] The DC12V power interface terminal 3 is connected to a computer power supply to provide DC12V power supply for the test interfaces (1, 2, 3, 4), and provides DC5V power supply for the test interfaces (1, 2, 3, 4) through a DC12V to DC5V step-down circuit (a, b, c, d); the DC5V of each interface is an independent DC12V to DC5V step-down circuit to avoid unstable power supply caused by overload.

[0033] The horizontal U.2 female connector 2 is respectively arranged on the front and back of the circuit board 1, including two horizontal U.2 female connectors (interface 1 and interface 3) on the front and two horizontal U.2 female connectors (interface 2 and interface 4) on the back; the input end of the horizontal U.2 female connector 2 is connected to the step-down circuit 4, and the output end is connected to the U.2 enterprise-level solid-state drive with the SATA protocol, which is used to provide a dual-voltage power supply of DC5V and DC12V for the enterprise-level solid-state drive;

[0034] The reinforcing device 5 is arranged in the center of the circuit board 1 to assist in fixing the circuit board 1 and the enterprise-level solid-state hard drive; the side of the circuit board 1 is connected and reinforced with the computer chassis mounting bracket by screws, and is fixed to the computer chassis through the mounting bracket.

[0035] Through the above embodiments, this application adopts the DC12V of an external computer power supply as the power supply source, which effectively solves the problem of ultra-large power demand faced by multi-interface large-capacity enterprise-level solid-state hard drives during the testing process; for each test interface, a separate DC12V to DC5V step-down circuit is equipped to avoid the power supply instability caused by overload. At the same time, the independent step-down circuit also effectively reduces the risk of burning circuit components due to excessive temperature, further improving the overall stability and safety of the test equipment; the use of reinforced structure and auxiliary reinforcement measures not only enhances the overall vibration resistance of the test equipment, but also effectively alleviates the pressure of the U.2 female connector in the vertical direction.

[0036] In one possible implementation, Figure 3 As shown, the step-down circuit includes a chip U1, a capacitor CS1, a capacitor CX1, a capacitor C15, a capacitor CB1, a capacitor CF1, an inductor L1, a resistor RA1, a resistor RB1, a capacitor CX2, a capacitor CS2 and a diode D1, wherein,

[0037] One end of the capacitor CS1 and the capacitor CX1 is connected to the DC12V power supply and the 5th pin of the chip U1, and the other end of the capacitor CS1 and the capacitor CX1 is connected to the ground and the lower 7th pin of the chip U1;

[0038] One end of the capacitor C15 is connected to the second pin of the chip U1, and the other end of the capacitor C15 and the eighth pin of the chip U1 are grounded;

[0039] The third pin of the chip U1 is connected to one end of the capacitor CB1, the other end of the capacitor CB1 is connected to the fourth pin of the chip U1 and one end of the inductor L1, and the other end of the inductor L1 is grounded through the capacitor CX2, the capacitor CS2 and the diode D1 respectively;

[0040] The other end of the inductor L1 is connected to the 4th pin of the chip U1 through the capacitor CF1 , and the other end of the inductor L1 is connected to the GND pin of the chip U1 through the resistors RA1 and RB1 .

[0041] In a possible implementation, the chip U1 in the step-down circuit 5 is a power management chip with high performance, low power consumption and overheat protection functions to ensure the stability and safety of the step-down process.

[0042] Optionally, the chip U1 adopts the MT3901 switching power supply chip, wherein the DC12V external power supply is input from the 5th pin of U1 and output from the 4th pin through capacitors CS1 (filtering high-frequency noise) and CX1 (filtering low-frequency noise), and the capacitor CS1 is used to filter high-frequency noise, and the capacitor CX1 is used to filter low-frequency noise; then energy storage and energy conversion are performed through the inductor L1 to output a linear and stable DC power supply, and then through capacitors CX2 (filtering low-frequency noise) and CS2 (filtering high-frequency noise) to provide a stable DC5V power output.

[0043] At the same time, the first pin of the chip U1 receives a feedback signal, pulls up the signal through the resistor RA1 and pulls down the signal through RB1, obtains feedback information, controls the operating frequency of the chip U1, and adjusts the output voltage of the fourth pin of the chip U1; among them, the diode D1 is a TVS (transient voltage suppression diode) diode, which is used to protect the circuit from damage by instantaneous overvoltage.

[0044] In one possible implementation, Figure 4 As shown, the reinforcing device 5 includes a compression spring 51, a screw 52 and a compression rod 53, wherein:

[0045] The pressure rod 53 is T-shaped and has a through hole 531 at the center. The side wall of the through hole 531 is provided with a thread. The screw 52 is a flat head screw, which is screwed into the pressure rod 53 after being sleeved with the pressure spring 51.

[0046] By adjusting the downward pressure through the screw 52, ​​the compression spring 51 releases its elastic force to press the pressure rod 53, pressing the solid-state hard drive to achieve auxiliary reinforcement; secondly, the shell with metal heat dissipation function is heavy, and the pressure on the U.2 female connector is relatively large. The reinforcement device of this application can relieve the pressure on the connector.

[0047] In a possible implementation, the circuit board 1 is clad with multiple layers of copper near the enterprise-level solid-state drive and interconnected through vias to facilitate heat dissipation of the solid-state drive.

[0048] In one possible implementation, the horizontal U.2 female connector on the back of the circuit board is arranged on the side of the circuit board and arranged vertically, leaving sufficient space for circuit routing.

[0049] In one possible implementation, the circuit board further includes a highly integrated status indicator light module, which includes multiple LED indicator lights. Specifically, the status indicator light module includes:

[0050] Power status indicator: A high-brightness red LED is used. When the DC12V power supply is properly connected, the indicator lights up steadily, indicating that the power supply is normal. If the power is disconnected or faulty, the indicator goes out.

[0051] Output voltage indicator: It uses a green LED. When the step-down circuit successfully converts DC12V to DC5V and outputs it stably, the indicator lights up, indicating that the output voltage is normal.

[0052] Data transfer indicator: This indicator uses a blue LED. When data is being transferred between the U.2 enterprise-class solid-state drive and the aging board, the indicator flashes at a certain frequency, indicating that data transfer is in progress.

[0053] Error alarm indicator: uses a yellow or red flashing LED. When any problem that may affect system stability is detected, such as power failure, data transmission error, hardware abnormality, etc., the indicator flashes to alert the user and take appropriate measures.

[0054] In one possible implementation, the horizontal U.2 female connector is designed with a precise anti-fool-proofing structure, which includes but is not limited to physical anti-fool-proofing measures such as positioning grooves, positioning holes or positioning protrusions, and also integrates an electrical anti-fool-proofing mechanism. Specifically:

[0055] Physical identification: Use structures such as positioning grooves and positioning protrusions on the connector to ensure that the U.2 enterprise-class SSD is correctly aligned during insertion and prevent reverse insertion. These structures should be designed to be obvious and strong enough so that users can easily identify and operate the drive correctly when inserting it.

[0056] Electrical foolproofing: The connector's pinout and electrical signal detection mechanism ensure that when a hard drive is inserted incorrectly, the circuitry automatically detects and blocks power and signal connections. This electrical foolproofing improves system security and stability, preventing hardware damage or data loss caused by misoperation.

[0057] In one possible implementation, the edge of the circuit board is provided with a plurality of heat dissipation holes to improve heat dissipation efficiency. In addition, heat dissipation devices such as a heat dissipation fan or a heat sink may be installed on the front and / or back of the circuit board to further enhance heat dissipation performance. Specifically:

[0058] Heat dissipation hole design: Heat dissipation holes should be evenly distributed around the edge of the circuit board to ensure that heat can be evenly dissipated into the surrounding environment. The size and number of heat dissipation holes should be accurately calculated and designed based on factors such as the size of the circuit board, power consumption, and operating environment.

[0059] Cooling fan / heat sink design: The selection and installation of cooling fans or heat sinks should take into account factors such as power consumption, noise, and heat dissipation effectiveness. For example, low-noise, high-efficiency cooling fans or large-area heat sinks can reduce system temperature and improve stability. The design of cooling devices should also consider ease of maintenance and replacement, ensuring quick replacement or cleaning when necessary.

[0060] The above is a specific description of the preferred implementation of the present invention, but the invention of the present invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
