[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] The core of the present invention is to provide an M.2 solid-state hard disk module, which can realize the hot-swap function of the M.2 solid-state hard disk, ensure the continuity and reliability of system operation, and realize the replacement and maintenance of the hard disk when the server is running. Another core of the present invention is to provide a server including the above-mentioned M.2 solid-state hard disk module.

[0053] The M.2 solid state drive module provided by the present invention includes a module bracket, an adapter card 7, an M.2 solid state drive 5, and a backplane 4. Please refer to Figure 1 .

[0054] The adapter card 7 and the backplane 4 are both arranged on the module bracket, and the adapter card 7 is plugged into the hot-swap connector 401 on the backplane 4 to realize signal transmission between the two. The hot-swap connector 401 is a connector with a hot-swappable interface, such as a SATA interface, an E-SATA interface, or a SAS interface.

[0055] The signal of the M.2 solid state drive 5 is connected to the adapter board 7, and the signal of the M.2 solid state drive 5 is converted into a pluggable signal through the adapter board 7, and then the signal transmission is realized by plugging the adapter board 7 and the hot-plug connector 401. The pluggable function of the M.2 solid state drive 5 is indirectly realized by the hot-pluggable setting between the adapter board 7 and the hot-plug connector 401, which is convenient for the operation and maintenance of the M.2 solid state drive 5. In addition, the hot-plug function can also ensure the continuity and reliability of the system operation, and can realize the replacement and maintenance of the hard disk when the server is running, such as repairing the hard disk fault and cleaning the hard disk drive; the hot-plug function also simplifies the maintenance process of the server, facilitates the server configuration replacement and upgrade and expansion of storage capacity, data migration and backup, etc., and improves the maintainability and availability of the server.

[0056] In a specific embodiment, the adapter board 7 can be moved to approach or move away from the hot-plug connector 401 to achieve connection or disconnection between the adapter board 7 and the backplane 4. When the adapter board 7 and the hot-plug connector 401 are plugged in, the signal transmission between the M.2 solid-state drive 5 and the backplane 4 is achieved; and based on the hot-pluggable setting between the hot-pluggable connector 401 and the adapter board 7, the pluggable function of the adapter board 7 and the M.2 solid-state drive 5 as a whole is achieved, indirectly achieving the effect of hot-pluggable M.2 solid-state drive 5.

[0057] In another specific embodiment, the hot-swap connector 401 can be moved to be closer to or farther from the adapter board 7 to achieve connection or disconnection between the adapter board 7 and the backplane 4. When the adapter board 7 and the hot-swap connector 401 are plugged in, the signal transmission between the M.2 solid-state drive 5 and the backplane 4 is achieved; and the hot-swappable setting between the hot-swappable connector 401 and the adapter board 7 indirectly achieves the effect of hot-swappability of the M.2 solid-state drive 5.

[0058] In another specific embodiment, the hot-swap connector 401 and the adapter board 7 can be moved to achieve a closer or farther relationship between the two. When the adapter board 7 and the hot-swap connector 401 are plugged in, the M.2 solid-state drive 5 and the backplane 4 achieve signal connectivity. The hot-swap function of the M.2 solid-state drive 5 is achieved by utilizing the hot-swappable connection between the adapter board 7 and the hot-swap connector 401.

[0059] The above three specific implementation methods can be set in combination with the actual installation situation. For example, if it is inconvenient to move the hot-swap connector 401 and the adapter board 7 at the same time when installing in the chassis, then either the hot-swap connector 401 or the adapter board 7 can be moved for plugging and unplugging. If the hot-swap connector 401 and the adapter board 7 can be connected before installation in the chassis or there is space for docking the two in the chassis, then both of them can be moved for plugging and unplugging.

[0060] After the hot-swap connector 401 and the adapter board 7 are connected, the signal between the backplane 4 and the motherboard can be further connected, that is, the signal connection between the M.2 solid-state drive 5 and the motherboard is realized, and the M.2 solid-state drive 5 can be hot-swappable relative to the motherboard.

[0061] The above-mentioned M.2 solid-state hard disk module, through the setting of the adapter board 7 and the hot-plug connector 401, realizes the conversion of the interface signal of the M.2 solid-state hard disk 5 into a hot-plug signal, and indirectly realizes the hot-plug function of the M.2 solid-state hard disk 5 by plugging the adapter board 7 and the hot-plug connector 401 on the backplane 4. The overall structure is simple and plugging and unplugging are convenient, which can improve the maintainability, reliability and availability of the server.

[0062] Based on the above embodiment, the hot-swap connector 401 is an E1.s interface connector, that is, a connector with an E-SATA interface. As a connector with high strength and strong anti-electromagnetic interference capability, the E-SATA interface can ensure that the interface still has good performance after multiple hot-plugging and reduce the static electricity generated during the hot-plugging process.

[0063] The logic process of realizing the hot-swappable function of the hard disk is as follows: insert the M.2 solid-state hard disk 5 into the adapter board 7 to realize the signal transmission between the two, the adapter board 7 converts the M.2 interface signal of the M.2 solid-state hard disk 5 into the E1.s interface signal, inserts the adapter board 7 into the E1.s interface connector on the backplane 4, and the backplane 4 is connected to the mainboard through a cable to realize data transmission. In this process, the connection between the adapter board 7 and the E1.s interface connector on the backplane 4 is hot-swappable, so the M.2 solid-state hard disk 5 and the adapter board 7 as a whole can be hot-swapped with the backplane 4, which indirectly realizes the hot-swappable function of the M.2 solid-state hard disk 5.

[0064] Furthermore, at least two E1.s interface connectors are provided to connect at least two M.2 solid-state drives 5 , and at least two corresponding adapter cards 7 are also provided to achieve hot-swappable function of at least two M.2 solid-state drives 5 .

[0065] Taking the case where the backplane 4 is fixed to the module bracket as an example, at least two hot-plug connectors 401 are arranged on the backplane 4, and at least two adapter boards 7 can be synchronously moved to be plugged with the corresponding hot-plug connectors 401, or at least two adapter boards 7 can be separately moved to be plugged with the corresponding hot-plug connectors 401. After the adapter board 7 and the hot-plug connector 401 are plugged to complete the signal transmission, the signal transmission between the M.2 solid-state drive 5 and the backplane 4 is completed. By making the adapter board 7 and the M.2 solid-state drive 5 hot-pluggable relative to the backplane 4 as a whole, the hot-plug function of the M.2 solid-state drive 5 is indirectly realized, so that the M.2 solid-state drive 5 can be removed or replaced without shutting down the system or cutting off the power supply, without affecting the normal operation of the server, and facilitating the disassembly and maintenance of the hard disk.

[0066] Based on any of the above embodiments, the plug interface of the hot-swap connector 401 extends out of the backplane 4, specifically between the front end of the backplane 4 and the rear end of the adapter card 7. Figure 1 The middle arrow indicates the front and rear ends of the adapter card 7 in the plugging direction.

[0067] A gold finger assembly 702 is provided at the rear end of the adapter card 7 , and the adapter card 7 can be moved so that the gold finger assembly 702 is inserted into the plug interface of the hot-swap connector 401 to achieve signal transmission between the adapter card 7 and the backplane 4 .

[0068] In a specific embodiment, the gold finger assembly 702 extends out of the rear end of the adapter board 7 to facilitate plugging with the plug interface of the hot plug connector 401. Specifically, the length of the gold finger assembly 702 is not less than the depth of the plug interface, thereby ensuring reliable plugging between the adapter board 7 and the hot plug connector 401 and ensuring reliable and stable transmission of signals.

[0069] In another specific embodiment, the gold finger assembly 702 does not extend beyond the rear end of the adapter board 7, and both sides of the gold finger assembly 702 have insertion gaps to facilitate the insertion of the gold finger assembly 702 and the hot plug connector 401. The two sides of the gold finger assembly 702 here specifically refer to the front and back sides.

[0070] In order to ensure the reliable connection between the gold finger assembly 702 and the hot plug connector 401, a limiter can be set on the back panel 4 to limit the displacement of the hot plug connector 401. The limiter is set on the front and rear sides of the hot plug connector 401 to ensure the accuracy and reliability of the gold finger assembly 702 moving along the plugging direction to plug with the hot plug connector 401, and avoid the displacement of the hot plug connector 401 due to the plugging force.

[0071] Based on any of the above embodiments, the module bracket includes an adapter bracket 6 and a bottom bracket 1, wherein the adapter board 7 is connected to the adapter bracket 6, the adapter bracket 6, the adapter board 7, and the M.2 solid-state hard drive 5 form an integral component, and the backplane 4 is connected to the bottom bracket 1 to form another integral component. The two integral components can move relative to each other to connect the signal between the backplane 4 and the adapter board 7, and the hot-swap function of the M.2 solid-state hard drive 5 is indirectly realized by using the hot-swap connector 401 on the backplane 4.

[0072] Specifically, the adapter bracket 6 can move on the bottom bracket 1, that is, the plug-in process is specifically that the integral component formed by the adapter bracket 6, the adapter board 7, and the M.2 solid-state drive 5 slides to approach or move away from the backplane 4 on the bottom bracket 1 to achieve the plug-in and separation between the adapter board 7 and the hot-swap connector 401.

[0073] In a specific embodiment, a slide rail may be provided on the bottom bracket 1 to facilitate the sliding of the adapter card 7 for guidance during plugging, thereby ensuring the accuracy and effectiveness of the plugging and unplugging operation between the adapter card 7 and the hot-swap connector 401 .

[0074] For example, if the plug interface of the hot-plug connector 401 arranged on the backplane 4 is arranged upward, the adapter board 7, the adapter bracket 6 and the M.2 solid-state drive 5 slide from top to bottom along the bottom bracket 1 and are plugged into the plug interface of the hot-plug connector 401 from top to bottom.

[0075] Alternatively, if the plug interface of the hot-swap connector 401 disposed on the backplane 4 is disposed to the left, the adapter board 7, the adapter bracket 6 and the M.2 solid-state drive 5 slide from left to right along the bottom bracket 1 and are plugged into the plug interface of the hot-swap connector 401 from top to bottom.

[0076] The up, down, left, and right in the above two processes are based on Figure 1 benchmark.

[0077] In summary, by fixing the M.2 solid-state drive 5 and the adapter board 7 on the adapter bracket 6, the adapter bracket 6 can slide along the internal slide of the M.2 hard disk module, insert the gold finger assembly 702 of the adapter board 7 into the E1.s connector interface of the backplane 4 to achieve positioning, and accurately insert the adapter board 7 into the connector to achieve hot plugging of the M.2 solid-state drive 5.

[0078] Based on any of the above embodiments, the bottom bracket 1 includes an enclosing cavity, and a sliding entrance is provided on one side of the enclosing cavity. The integral component formed by the adapter bracket 6, the adapter board 7, and the M.2 solid-state drive 5 enters the enclosing cavity from the sliding entrance, and is pushed forward to be plugged into the hot-swap connector 401 through a sliding connection with the enclosing cavity.

[0079] By setting up the surrounding cavity, on the one hand, space is provided for the sliding of the adapter bracket 6, and on the other hand, the adapter bracket 6, the adapter board 7, and the M.2 solid-state drive 5 are limited and protected to ensure the safety of the components and the reliable and stable operation.

[0080] Taking a specific implementation as an example, the sliding entrance is arranged on the side of the enclosing cavity, and the plug-in interface of the hot-plug connector 401 is arranged relative to this side. When plugging in, the adapter bracket 6, the adapter board 7, and the M.2 solid-state hard drive 5 as a whole enter from the sliding entrance and move to the right to be plugged into the hot-plug connector 401.

[0081] A top bracket 2 is connected to the top of the surrounding cavity, and a slide bracket 3 is connected to the bottom of the surrounding cavity. The surrounding cavity, the top bracket 2, and the slide bracket 3 form a frame structure, such as Figure 1The top bracket 2 and the bottom bracket 1 are connected by the first riveted portion 101 and the riveted piece to form a cavity surrounding the cavity. The slideway bracket 3 is connected with the bottom bracket 1 and the top bracket 2 by the second riveted portion 301 and the riveted piece to form a fixed connection.

[0082] By providing a slideway on at least one of the surrounding cavity, the top bracket 2 and the slideway bracket 3, a sliding path of the adapter bracket 6 is constrained and guided, that is, a guide is provided for the plugging of the adapter card 7 and the hot-swap connector 401.

[0083] For example, slideways can be set in the enclosing cavity, the top bracket 2, and the slide bracket 3, so that the adapter bracket 6 has sliding guides in multiple directions when sliding, ensuring the accuracy and effectiveness of the plugging and unplugging operations, and if one of the slide guides fails, the other slides can still serve as sliding guides, ensuring the long-term stability and reliability of the plugging and unplugging operations.

[0084] The adapter board 7 can be driven by the sliding contact between the adapter bracket 6 and the slideway, thereby avoiding the problem of component wear caused by direct contact between the adapter board 7 and the slideway, and ensuring the service life of the components.

[0085] In a specific embodiment, based on the sliding connection between the adapter bracket 6 and the slide, limit members can also be set on both sides of the sliding direction of the slide to prevent the adapter bracket 6 from sliding beyond the limit and causing damage to components or slipping, thereby ensuring the reliable stability of the connection between the adapter board 7 and the hot-swap connector 401.

[0086] The top bracket 2 is used to cover the top of the enclosing cavity. The top bracket 2 can be detachably connected to the enclosing cavity. When the slide entrance is inconvenient to operate, the top bracket 2 can be opened to repair or replace the M.2 solid-state hard drive 5 connected to the adapter board 7 on the adapter bracket 6.

[0087] The slide bracket 3 is arranged at the bottom of the bottom bracket 1, that is, the bottom of the surrounding cavity, and is used to provide guidance for the sliding of the adapter bracket 6 to ensure the accuracy and effectiveness of the insertion.

[0088] Based on any of the above embodiments, the adapter bracket 6 includes a front end assisting portion 603 and a rear end bracket plate 602 connected thereto, wherein the front end assisting portion 603 is a component provided for easy plugging and unplugging, and the rear end bracket plate 602 and the assisting handle 601 are riveted and fixed together by a third riveting portion 6021 in cooperation with a rivet member.

[0089] Specifically, a power-assisting handle 601 is provided at the front end of the front-end power-assisting part 603, and the rotating end of the power-assisting handle 601 is rotatably connected to the front-end power-assisting part 603 through a rotating shaft, and the power-assisting handle 601 is rotated to lock or unlock the front-end power-assisting part 603; when the buckling part 6011 of the power-assisting handle 601 is locked to the front-end power-assisting part 603, the corresponding plug-in process is completed and no power-assisting is required; when the buckling part 6011 of the power-assisting handle 601 is unlocked relative to the front-end power-assisting part 603, the power-assisting handle 601 can be rotated to provide power-assisting when plug-in is required.

[0090] Taking a specific implementation as an example, the axial direction of the rotating shaft is parallel to the height direction of the bottom bracket 1, and the height direction of the bottom bracket 1 is perpendicular to the plugging direction of the hot-plug connector 401. The power-assisting handle 601 can be rotated left and right relative to the front-end power-assisting part 603, and the left and right rotation of the power-assisting handle 601 is used to assist the plugging and unplugging operation of the adapter bracket 6.

[0091] Taking another specific implementation as an example, the axial direction of the rotating shaft is parallel to the width direction of the bottom bracket 1, and the width direction of the bottom bracket 1 is perpendicular to the plugging direction of the hot-plug connector 401. The power-assisting handle 601 can be rotated up and down relative to the front-end power-assisting part 603, and the up and down rotation of the power-assisting handle 601 is used to assist the plugging and unplugging operation of the adapter bracket 6.

[0092] When the power-assisting handle 601 is in use, the adapter bracket 6, the adapter board 7 and the M.2 solid-state hard drive 5 have been assembled into an integral component and extended into the enclosing cavity of the bottom bracket 1. With the help of the power-assisting effect that the power-assisting handle 601 can provide when it is in the unlocked state and the guiding effect of the slide, the integral components of the adapter bracket 6, the adapter board 7 and the M.2 solid-state hard drive 5 are pushed toward the direction close to the hot-plug connector 401, so that the adapter board 7 and the hot-plug connector 401 can be reliably plugged in. After the plugging is completed, the power-assisting handle 601 can be rotated to lock it on the front power-assisting part 603.

[0093] In addition, the front end assisting portion 603 is connected to the side wall of the sliding entrance through an elastic sheet. When the front end assisting portion 603 is inserted into the sliding entrance, the elastic sheet is compressed, so that the adapter bracket 6 and the bottom bracket 1 are in reliable contact, ensuring the reliable stability of the connection between the adapter board 7 and the hot-swap connector 401.

[0094] On the basis of any of the above embodiments, the rotating part of the power-assisting handle 601 is connected with a stopper 6012, and the stopper 6012 is arranged in the operation hole 6031 of the front power-assisting part 603;

[0095] When the power-assisting handle 601 is rotated and the stop portion 6012 is tilted in the working hole 6031, the stop portion 6012 contacts the wall of the stop hole 202 at the front end of the top bracket 2, and a power-assisting effect is generated through the contact to assist in pushing the adapter bracket 6 toward the direction close to the hot-plug connector 401, so that the adapter board 7 and the hot-plug connector 401 can be effectively and reliably plugged into place; by setting the power-assisting handle 601, a power-assisting effect is provided for the plugging of the adapter board 7 and the hot-plug connector 401, so that the operator can complete the plugging easily and labor-savingly.

[0096] After the plugging is completed, the power-assisting handle 601 is rotated so that the stop portion 6012 is vertically arranged in the working hole 6031. In this state, the power-assisting handle 601 is locked on the front power-assisting portion 603;

[0097] If it is necessary to pull out the adapter bracket 6, the power-assisting handle 601 is manually released to make the power-assisting handle 601 in a rotatable state, and the stop portion 6012 is tilted in the operating hole 6031. The adapter bracket 6, the adapter board 7 and the M.2 solid-state drive 5 can be pulled out by manually pulling the power-assisting handle 601.

[0098] Based on any of the above embodiments, a board connector 701 connected to the rear end of the M.2 solid-state hard drive 5 is provided on the adapter board 7, and at least one limiting portion for limiting the front end support of the M.2 solid-state hard drive 5 is provided in the length direction of the adapter board 7; for M.2 solid-state hard drives 5 of different lengths, the M.2 solid-state hard drive 5 can be fixedly limited by limiting portions at different positions, thereby improving the overall applicability of the adapter board 7 and the adapter bracket 6.

[0099] When the M.2 solid-state hard drive 5 and the adapter board 7 are plugged in, the front end of the M.2 solid-state hard drive 5 is supported on the limit portion, and the rear end is directly connected to the board connector 701 on the adapter board 7. After the connection of the M.2 solid-state hard drive 5 is completed, the adapter board 7 and the M.2 solid-state hard drive 5 are connected through the sliding connection of the adapter bracket 6 and the slide rail, and the gold finger assembly 702 of the adapter board 7 and the hot-swap connector 401 are reliably plugged in.

[0100] Furthermore, the limiting portion includes a stud 6026 which is detachably connected to the adapter board 7, and a step groove is provided on the stud 6026 for clamping the front end of the M.2 solid-state drive 5. The stud 6026 is connected to a screw to limit the M.2 solid-state drive 5 in the step groove, so as to clamp and limit the front end of the M.2 solid-state drive 5 in the step groove, thereby ensuring the stability and reliability of the M.2 solid-state drive 5 as a whole on the adapter board 7, and avoiding the front end deviation of the M.2 solid-state drive 5 caused by transfer and transportation, which affects the stability and effectiveness of signal transmission between it and the adapter board 7.

[0101] Specifically, the stud 6026 is connected to the special-shaped hole 6025 of the adapter bracket 6, and multiple special-shaped holes 6025 are arranged along the length direction of the adapter bracket 6 to correspond to the limiting fixation of M.2 solid-state drives 5 of different lengths. Each length of the M.2 solid-state drive 5 corresponds to a special-shaped hole 6025 at a position connected to the stud 6026 and the screw.

[0102] Specifically, the middle of the special-shaped hole 6025 is a circular threaded hole, which is convenient for the fixed connection of the stud 6026; the two ends of the special-shaped hole 6025 are square holes, and the aperture of the square hole is smaller than the aperture of the circular threaded hole. The setting of the square hole is used to avoid radial movement of the stud 6026, thereby ensuring a reliable and stable connection between the stud 6026 and the special-shaped hole 6025 as a whole.

[0103] In addition, a plurality of openings are provided on the side of the surrounding cavity of the bottom bracket 1. The openings are used for visualization and weight reduction. The side here is arranged adjacent to the side where the sliding entrance is located. During the plugging, the openings can be used to observe the specific plugging situation, which is convenient for operators to perform visual management and operation. In addition, the provision of the openings can facilitate the reduction of the weight of the bottom bracket 1, the weight of the entire M.2 solid state drive module, and meet the requirements of lightweight design.

[0104] Please refer to Figure 4 , Figure 5 The rear end bracket plate 602 is provided with folded edges on both sides perpendicular to the plug-in direction of the M.2 solid-state hard drive 5, and the projection of any folded edge on the bottom plane of the adapter bracket 6 is greater than or equal to the projection of the M.2 solid-state hard drive 5 on the bottom plane of the adapter bracket 6. The M.2 solid-state hard drive 5 is covered and surrounded in the adapter bracket 6 by the setting of the folded edges, so as to avoid the M.2 solid-state hard drive 5 from colliding with other components during the plug-in process and ensuring the reliability and safety of the plug-in of the M.2 solid-state hard drive 5 and the adapter board 7.

[0105] For further information, please refer to Figure 2 The slideway specifically includes a first bending portion 203 provided on the top bracket 2 and a second bending portion 302 provided on the slideway bracket 3. The first bending portion 203 and the second bending portion 302 are used for sliding limit of at least one of the two opposite sides of the adapter bracket 6. Here, the two opposite sides of the adapter bracket 6 are the two sides along the length direction of the adapter bracket 6.

[0106] Taking a specific implementation as an example, the first bending portion 203 and the second bending portion 302 are used to limit one side of the adapter bracket 6, that is, the first bending portion 203 and the second bending portion 302 both have a folded edge, and this folded edge and the side of the adapter bracket 6 are released to achieve sliding guidance and sliding limitation, thereby avoiding the situation where the adapter board 7 and the hot-swap connector 401 cannot be properly plugged in due to sliding deviation.

[0107] Taking another specific implementation as an example, the first bending portion 203 and the second bending portion 302 are used to limit the relative two side portions of the adapter bracket 6, that is, the first bending portion 203 and the second bending portion 302 each have two folded edges, and the two folded edges correspond to the limiting of the relative two side portions. The double-sided limiting ensures reliable guidance of the plug-in process and ensures the accuracy and effectiveness of the plug-in.

[0108] Please refer to Figure 5 , Figure 4 , either the adapter board 7 and the adapter bracket 6 is provided with a fixing screw 703, and the other is provided with a stud, and the stud is connected to the fixing screw 703; the stud specifically includes a fixing stud 6023 and a positioning stud 6024, wherein the positioning stud 6024 is provided with a step surface that fits the adapter board 7, the thickness of the adapter board 7, i.e., the distance between the step surface and the top surface of the positioning stud 6024, the adapter board 7 is abutted on the step surface to achieve positioning; further, after positioning by the positioning stud 6024, the fixing stud 6023 and the adapter board 7 are also aligned, and tightening the fixing screw 703 can ensure the fastening reliability of the connection between the adapter board 7 and the adapter bracket 6.

[0109] like Figure 4 The fixing studs 6023 and the positioning studs 6024 are arranged at four corners, and the positioning studs 6024 are arranged at the adjacent corners of the fixing studs 6023, which facilitates positioning while ensuring convenient and reliable connection.

[0110] In addition, either the adapter board 7 or the adapter bracket 6 is provided with a positioning pin 6022 for positioning the two. The positioning pins 6022 are arranged on both sides of the M.2 solid-state drive 5. The positioning pins 6022 are for initial positioning, and the positioning studs 6024 are for secondary positioning, ensuring the accuracy and effectiveness of the connection between the adapter board 7 and the adapter bracket 6.

[0111] In a more preferred implementation manner, the positioning pin 6022 is disposed on the adapter bracket 6 to avoid processing of the adapter card 7 and ensure effective reliability of signal transmission of the adapter card 7 .

[0112] The positioning pins 6022 are arranged on both sides of the M.2 solid state drive 5 , so as to realize the connection and positioning of the adapter board 7 and the adapter bracket 6 without affecting the connection between the M.2 solid state drive 5 and the adapter board 7 .

[0113] Based on any of the above embodiments, the back panel 4 and the bottom bracket 1 are connected by fasteners, and a step is provided on the top of the fasteners to create a height difference between the back panel 4 and the bottom bracket 1; the fasteners specifically include step studs 105 and connecting studs 104, wherein the step studs are studs with steps, and the step is provided to create a height difference between the back panel 4 and the bottom bracket 1 so as to leave space between the two for installing other components on the back panel 4.

[0114] For details, please refer to Figure 1 , Figure 3 There are 4 connecting holes on the back plate 4, of which the two larger first connecting holes 402 are used to cooperate with the step studs 105 on the bottom bracket 1 to achieve the positioning of the back plate 4 during installation, and the two smaller second connecting holes 403 cooperate with the connecting studs 104 on the bottom bracket 1. The four groups of connecting holes are screwed to fix the back plate 4 to the bottom bracket 1.

[0115] Please refer to Figure 1 The plug interface of the hot-swap connector 401 is vertically arranged, and at least two M.2 solid-state hard disks 5 are vertically arranged in the surrounding cavity. Figure 1 , Figure 5 As shown, the space occupied by the entire module is reduced by vertically arranging it, so as to save space on the server.
