Detailed implementation manners

[0029] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions in the present invention will be clearly and completely described below with reference to the accompanying drawings in the present invention. Apparently, the described embodiments are some but not all of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without making creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0030] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement conditions between components in a specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indications will also change accordingly.

[0031] In addition, the descriptions involving "first", "second", etc. in the embodiments of the present invention are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the fact that those of ordinary skill in the art can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0032] Before describing the technical solution of the present invention, the technical background of the present invention will be described first.

[0033] Currently, the physical form of a mechanical hard disk is a 3.5-inch hard disk, and most solid-state drives (SSDs) are in the form of 2.5-inch hard disks. Among them, the 3.5-inch hard disk has a length of 147 mm, a width of 101.6 mm, and a thickness of less than 26.1 mm; while the 2.5-inch hard disk has a maximum length of 101.85 mm, a width of 69.85 mm, and different thickness specifications, ranging from 5 mm to 19.05 mm. According to different business applications, there may be a situation where 3.5-inch hard disks and 2.5-inch hard disks are mixed in some server models. The capacities of 3.5-inch mechanical hard disks range from 250 GB to 14 TB, and the commonly used capacity on servers is 10 TB. The capacities of 2.5-inch SSDs are mostly from 128 GB to 4 TB, and the higher the capacity, the more expensive the price.

[0034] In the case where both 3.5-inch hard disks and 2.5-inch hard disks need to be used on the same storage server, since the bracket specifications suitable for 3.5-inch hard disks and 2.5-inch hard disks are different, if the storage server slots are designed separately according to the sizes suitable for both, this will lead to cumbersome and lack of unity in work, and moreover, the specifications suitable for subsequent each slot are fixed, lacking flexibility and it is difficult to meet the user's customization requirements.

[0035] In the current related technology one, a bracket that is pre-designed to be compatible with both 3.5-inch hard disks and 2.5-inch hard disks is used. The bracket can also be compatible with 2.5-inch hard disks of different thicknesses and capacities. When it is necessary to increase the capacity of the solid-state drive, a 2.5-inch hard disk with a larger capacity can be replaced. However, this bracket can only be applied to specific occasions, that is, the compatibility design of the hard disk bracket needs to be considered at the beginning of product design, and it is not convenient for subsequent extended applications; and the upper limit of the hard disk capacity depends on the maximum capacity of a single hard disk, that is, only one solid-state drive can be installed in one hard disk bay; at the same time, a single hard disk slot cannot support redundant backup.

[0036] In related technology two, a 2.5-inch hard disk bracket is pre-designed, which can be directly installed into a 3.5-inch hard disk bay; and the 2.5-inch hard disk bracket can be compatible with solid-state drives of different thicknesses and capacities. When it is necessary to increase the capacity of the solid-state drive, a 2.5-inch hard disk with a larger capacity can be replaced. However, the upper limit of the hard disk capacity set in this bracket depends on the maximum capacity of a single hard disk, that is, only one solid-state drive can be installed in one hard disk bay; and a single hard disk slot cannot support redundant backup.

[0037] Based on this, the embodiments of the present invention provide a hard disk adapter device and a storage system, which can solve this technical problem.

[0038] Figure 1It is a schematic diagram of the overall appearance of the hard disk adapter device 10 provided by the present invention. Figure 2 It is a schematic diagram of the structures of various parts of the hard disk adapter device 10 provided by the present invention. Refer to Figure 1 and Figure 2 As shown, the hard disk adapter device 10 includes a housing 110 with a cavity inside, a hard disk bracket 120, and an adapter printed circuit board 130. The above-mentioned hard disk bracket 120 includes two parallel support surfaces 1201, and the two support surfaces 1201 are connected and arranged in the cavity inside the housing 110, and form two offset hard disk card slots with the cavity. Each hard disk card slot is respectively used for inserting a 2.5-inch hard disk 150. The above-mentioned adapter printed circuit board 130 is connected to one end of the housing 110. The adapter printed circuit board 130 includes two first connectors 1301. The positions of the first connectors 1301 on the adapter printed circuit board 130 correspond to the positions of the formed hard disk card slots. Each first connector 1301 is respectively used for electrically connecting with each 2.5-inch hard disk 150.

[0039] Among them, the material of the housing 110 can be a metal material (such as a steel plate, an aluminum plate, an aluminum alloy, etc.), or it can also be other materials, which are not specifically limited here. The housing 110 can be a hollow cube. The four sides (including the bottom, the top, and the sides) of the housing 110 can be closed planes, and its front end / front part and rear end / rear part can be unclosed surfaces. The front end can be used to insert a 2.5-inch hard disk, that is, to provide an insertion port for the 2.5-inch hard disk, and the rear end can be connected to the adapter printed circuit board 130. The inside of the housing 110 is hollow, that is, a cavity will be formed inside it, which is convenient for arranging the hard disk bracket 120 in the cavity.

[0040] For the hard disk bracket 120, its material can be a metal material (such as steel plate, aluminum plate, aluminum alloy, etc.), or it can also be other materials, which are not specifically limited here. The hard disk bracket 120 can include two supporting surfaces 1201, and both of these two supporting surfaces 1201 can be flat surfaces. One 2.5-inch hard disk is respectively placed on these two supporting surfaces 1201. The sizes of these two supporting surfaces 1201 can be set according to the size of the 2.5-inch hard disk. Generally, the width of the supporting surface 1201 will be greater than half of the width of the 2.5-inch hard disk, so as to ensure the stability of the 2.5-inch hard disk when installed on the supporting surface 1201. These two supporting surfaces 1201 are generally arranged in parallel, and the distance between the two supporting surfaces 1201 can be determined according to the thickness of the 2.5-inch hard disk to be inserted, and generally needs to be greater than the thickness of the 2.5-inch hard disk. After the hard disk bracket 120 is installed into the cavity inside the housing 110, the two supporting surfaces 1201 are longitudinally arranged in the cavity inside the housing 110. One supporting surface 1201 can form a hard disk slot with the bottom plate of the housing 110 closer to it, and another supporting surface 1201 and the previous supporting surface 1201 form another hard disk slot. These two hard disk slots can be respectively used to insert a 2.5-inch hard disk.

[0041] In addition, referring to Figure 3 the front / front-end schematic diagram of the hard disk adapter device 10 shown, here the two supporting surfaces 1201 of the hard disk bracket 120 are designed with a dislocation, so that two dislocated hard disk slots can be formed inside the housing 110. Here, the dislocation means that when two 2.5-inch hard disks are inserted onto the two supporting surfaces 1201, the left part of one 2.5-inch hard disk overlaps with the right part of the other 2.5-inch hard disk, and the rest does not overlap, that is, two hard disk slots with a left-right dislocation design are formed. Such a dislocation design can, when two 2.5-inch hard disks are inserted into the housing 110, not overly increase the width of the housing 110 and can keep the width of the housing 110 within a certain range.

[0042] Furthermore, positioning holes (such as threaded holes or through holes, etc.) for connecting with the housing 110 are respectively arranged on the sides of the above two supporting surfaces 1201. At the same time, corresponding positioning holes are also respectively arranged on the inner side and bottom of the housing 110. In this way, the two supporting surfaces 1201 of the hard disk bracket can be fixed inside the housing 110 through welding or self-riveting processes using the positioning holes, that is, the hard disk bracket 120 is connected inside the housing 110 to ensure the stability of the hard disk bracket 120 inside the housing 110. For the number of the threaded holes or through holes provided, it can be specifically set according to the actual situation.

[0043] The above hard disk adapter device 10 further includes an adapter printed circuit board 130. The adapter printed circuit board 130 can be a PCB board (Printed Circuit Board), and its size can be set according to the size of the rear end of the housing 110, generally smaller than the size of the rear end of the housing 110. The adapter printed circuit board 130 converts one hard disk interface into two hard disk interfaces. That is, two first connectors 1301 can be provided on the adapter printed circuit board 130. These two first connectors 1301 can be the same connectors. For example, they can both be vertical female headers (connectors). These two first connectors 1301 are respectively electrically connected to a 2.5-inch hard disk. The positions of these two first connectors 1301 on the adapter printed circuit board 130 correspond to the positions of the two formed hard disk slots. That is, one first connector 1301 correspondingly connects to the 2.5-inch hard disk inserted into one hard disk slot. These two first connectors 1301 can also be designed with a dislocation on the adapter printed circuit board 130, so that it is convenient for the 2.5-inch hard disks inserted into the two dislocated hard disk slots to be connected to the adapter printed circuit board 130. For the connection method between the above first connector 1301 and the 2.5-inch hard disk, it can be an electrical connection, so that the 2.5-inch hard disk can be accessed through the adapter printed circuit board 130.

[0044] As can be seen from the above description, the above hard disk adapter device 10 can be provided with two hard disk slots longitudinally for inserting two 2.5-inch hard disks. That is, one hard disk can be expanded / extended to two hard disks (specifically, two 2.5-inch hard disks are installed in a 3.5-inch hard disk bay), which is convenient for subsequent hard disk expansion applications and increases the hard disk capacity at the same time. In addition, when expanding / extending one hard disk to two hard disks, data can also be written into the two 2.5-inch hard disks simultaneously through the adapter printed circuit board 130, which can provide a redundant backup for storing data. When one hard disk is damaged, the data can still be obtained through the other hard disk, thus realizing the protection of data.

[0045] Furthermore, in order to facilitate the compatibility of the hard disk adapter device 10 with 3.5-inch hard disks, as an optional embodiment, the overall external dimension of the above hard disk adapter device 10 is the same as the external dimension of the 3.5-inch hard disk. That is, the length of the overall external shape of the above hard disk adapter device 10 is 147 mm, the width is 101.6 mm, and the thickness is 26 mm. In addition, there is an interface outside the hard disk adapter device 10, which is in the same position as the 3.5-inch hard disk, so that the hard disk adapter device 10 can be installed in the hard disk bay of the 3.5-inch hard disk.

[0046] In addition, it should be noted that the above components such as the housing 110 and the hard disk bracket 120 can all be processed by the sheet metal bending process, so the components and the process are simple, and the cost can be reduced.

[0047] In this embodiment, the hard disk adapter device includes a housing with a cavity inside, a hard disk bracket, and an adapter printed circuit board. The hard disk bracket includes two parallel support surfaces, which are connected and arranged inside the cavity of the housing, and form two misaligned hard disk slots with the cavity. Each hard disk slot is used to insert a 2.5-inch hard disk. The adapter printed circuit board is connected to one end of the housing. The adapter printed circuit board includes two first connectors, and the positions of the first connectors on the adapter printed circuit board correspond to the positions of the formed hard disk slots. Each first connector is used to electrically connect to each 2.5-inch hard disk. Through this hard disk adapter device, the installation method of a 3.5-inch hard disk can be compatible with the installation of two 2.5-inch hard disks, which is convenient for the later expansion and application of the hard disk and enables flexible configuration of the hard disk. At the same time, the longitudinal space of the original single hard disk slot is utilized to install two 2.5-inch hard disks to achieve redundant data backup, that is, the redundant backup transformation of supporting a single mechanical hard disk slot can be realized.

[0048] Figure 4 is a bottom schematic view of the hard disk adapter device 10 provided by an embodiment of the present invention. Refer to Figure 1 、 2 and Figure 4 As shown, the above-mentioned housing 110 includes a first bottom plate 1101, a second bottom plate 1102, and two first side plates 1103 respectively vertically connected to the first bottom plate 1101 and the second bottom plate 1102. The above-mentioned first bottom plate 1101, second bottom plate 1102, and two first side plates 1103 are connected to form the above-mentioned cavity. A first protruding member 1104 is provided on the first side of the first end of the first bottom plate 1101, and a second protruding member 1105 is provided on the second side of the first end of the second bottom plate 1102. The first side and the second side are two opposite sides.

[0049] Among them, the four sides of the housing 110 are composed of two bottom plates and two side plates. The bottom plate at the top of the housing 110 can be denoted as the first bottom plate 1101, and the bottom plate at the bottom can be denoted as the second bottom plate 1102. The first bottom plate 1101 and the second bottom plate 1102 can be two parallel plates. Both of the two side plates can be denoted as the first side plates 1103, and the two side plates can also be two parallel plates. The above-mentioned two first side plates 1103 are respectively vertically connected to the first bottom plate 1101 and the second bottom plate 1102 to form an enclosure box, and the inside of the enclosure box is the cavity inside the housing 110.

[0050] For the first base plate 1101, its front end is a hollow design, that is, it consists of a component in a rectangular area and a protruding component. These two components can be integrally formed, or they can be separately formed and then welded together, and no specific limitation is made here. The component in the rectangular area can be arranged at the rear end / rear part of the first base plate 1101 on the housing 110, and the protruding component can be denoted as the first protruding piece 1104, which can be arranged at the front end / front part of the first base plate 1101 on the housing 110, and specifically at the front end / front part of the first side (such as the left side) of the first base plate 1101.

[0051] For the second base plate 1102, its front end is also a hollow design, that is, it also consists of a component in a rectangular area and a protruding component. These two components can be integrally formed, or they can be separately formed and then welded together, and no specific limitation is made here.

Here, the second side and the above-mentioned first side are two side edges with opposite directions.

[0052] The two hollow components, the first protruding piece 1104 and the second protruding piece 1105, protrude from the housing 110, so that it is convenient for the user to insert or pull out the hard disk adapter device 10 from the chassis through these two protruding components. In addition, the length of the component in the rectangular area on the above-mentioned first base plate 1101 and the second base plate 1102 is slightly less than the length of the 2.5-inch hard disk, that is, when the 2.5-inch hard disk is inserted into the hard disk adapter device 10, some parts will protrude outside, so as to facilitate the insertion and extraction of the two 2.5-inch hard disks in the hard disk adapter device 10.

[0053] Furthermore, in order to make it more convenient to insert and pull out the hard disk adapter device 10 from the chassis, as an optional embodiment, handle holes are respectively arranged on the first protruding piece 1104 and the second protruding piece 1105. One handle hole can be respectively arranged on the first protruding piece 1104 and the second protruding piece 1105. The handle hole is a through hole, and its size can be set according to the actual situation, so that it is appropriate for the user's hand to pass through the handle hole to pull the hard disk adapter device 10, and no specific limitation is made here. In addition, the above-mentioned handle hole is generally a circular hole.

[0054] In addition, since a hard disk will be inserted into the hard disk adapter device 10, and the hard disk adapter device 10 is generally connected to the chassis so that the corresponding terminal or server in the chassis can access the hard disk in the hard disk adapter device 10, and heat dissipation problems will be involved during the process of accessing the hard disk. Based on this, as an optional embodiment, continue to refer toFigure 4 As shown, at least one ventilation hole 1106 is provided on each of the above-mentioned first bottom plate 1101 and second bottom plate 1102. The number of ventilation holes 1106 provided on the first bottom plate 1101 and the second bottom plate 1102 can be specifically set according to actual situations, and generally multiple ventilation holes 1106 are provided.

[0059] It should be noted that the positions of the fixing holes 1107 for the two 2.5-inch hard disks on the first side plate 1103 on the left side of the housing 110 are flush, the positions of the fixing holes 1107 for the two 2.5-inch hard disks on the first side plate 1103 on the right side of the housing 110 are flush, and the fixing holes 1107 for the two 2.5-inch hard disks on the first side plate 1103 on the left side of the housing 110 and the fixing holes 1107 for the two 2.5-inch hard disks on the first side plate 1103 on the right side of the housing 110 are not on the same horizontal line. They respectively correspond to fixing one 2.5-inch hard disk that is closer to the first side plate 1103 of the housing 110.

[0061] Among them, the two support surfaces 1201 of the hard disk bracket 120 are vertically connected by a side plate, and this side plate can be denoted as the second side plate 1202. The hard disk bracket 120 is concave in the direction facing the first side plate 1103 on the left side of the housing 110, that is, the two support surfaces 1201 of the hard disk bracket 120 and the second side plate 1202 form a concave shape after connection, and are used to support two 2.5-inch hard disks respectively.

[0062] In addition, inside the cavity of the above-mentioned housing 110, the distance between the above-mentioned second side plate 1202 and one first side plate 1103 is greater than or equal to the width of a 2.5-inch hard disk, and the distance between the above-mentioned second side plate 1202 and the other first side plate 1103 is greater than a preset distance. That is to say, the second side plate 1202 is away from the first side plate 1103 on the left side of the housing 110, and the distance between the second side plate 1202 and the first side plate 1103 on the left side can be greater than or equal to the width of a 2.5-inch hard disk, so that a 2.5-inch hard disk can be accommodated on the support surface 1201. In addition, the preset distance can be 0, or a distance value slightly greater than 0; the second side plate 1202 is close to the first side plate 1103 on the right side of the housing 110, and the second side plate 1202 and the first side plate 1103 on the right side of the housing 110 can be in direct contact or have a certain interval distance.

[0063] Furthermore, in order to ensure the connection stability between the hard disk bracket 120 and the housing 110, as an optional embodiment, one of the two support surfaces 1201 of the above-mentioned hard disk bracket 120 is connected to one first side plate 1103, and the other support surface 1201 is connected to the second bottom plate 1102. That is to say, on the left side of one support surface 1201 of the above-mentioned hard disk bracket 120 close to the first bottom plate 1101 of the housing 110 (i.e., close to the top of the housing 110), an L-shaped component is arranged facing upwards. The L-shaped component is close to the first side plate 1103 on the left side of the housing 110, and the support surface 1201 can be connected to the first side plate 1103 on the left side of the housing 110 through the L-shaped component. In addition, on the left side of the other support surface 1201 of the hard disk bracket 120 away from the first bottom plate 1101 of the housing 110, another L-shaped component is arranged facing downwards. The L-shaped component is close to the second bottom plate 1102 of the housing 110, and the support surface 1201 can be connected to the second bottom plate 1102 of the housing 110 through the L-shaped component.

These two first connectors 1301 can be vertical female connectors (plug connectors), which are respectively used for electrical connection with two 2.5-inch hard disks. The two first connectors 1301 can be arranged on one side close to the cavity of the housing 110, so that it is convenient for the two 2.5-inch hard disks inserted into the housing 110 to be respectively electrically connected to these two first connectors 1301.

Combining the above Figure 8 shown adapter printed circuit board 130, where multiple through holes can be provided on the adapter printed circuit board 130 (such as 7 through holes in the figure, which are respectively arranged at the four corners and the middle area of the adapter printed circuit board 130), and corresponding studs are also arranged at the corresponding positions on the mounting plate 140, so that it is convenient for the adapter printed circuit board 130 and the mounting plate 140 to be fixedly connected through these multiple studs and through holes, that is, to mount the adapter printed circuit board 130 on the mounting plate 140.

[0071] In addition, multiple through holes and studs are respectively arranged in the middle areas of the above-mentioned adapter printed circuit board 130 and the mounting plate 140, so as to avoid deformation of the adapter printed circuit board 130 during use and extend the service life of the adapter printed circuit board 130.

[0073] In this embodiment, the above hard disk adapter device may further include a mounting board for mounting the adapter printed circuit board, which can ensure the stability of the adapter printed circuit board and extend its service life.

[0074] The following embodiments will illustrate the circuit design and layout design of the adapter printed circuit board.

[0075] I. Circuit design of the adapter printed circuit board.

[0076] Interface standard compliance: Ensure that the schematic design follows the protocol and interface standards, including the specifications of the physical layer and the link layer. For example, the standard connector definition, power signal definition, etc. all follow the protocol and interface standards.

[0077] Signal integrity: Signal integrity needs to be considered during design, including the matching of differential signal pairs, impedance control, signal attenuation, and crosstalk reduction. For example, the design of differential equal-length lines, matching resistors, etc. all take into account the integrity design.

[0078] Power management: Design a reasonable power distribution network, including voltage regulators, filters, and decoupling capacitors, to ensure power stability and noise suppression. For example, considering the power management design, and then conducting the design of filter capacitors.

[0079] Compliance check: After the design is completed, conduct a compliance check to ensure that the design meets all relevant safety and performance standards. For example, after the schematic is completed, an electrical rule check needs to be carried out to modify warning and error issues.

[0080] II. Layout design of the adapter printed circuit board: Signal Integrity (SI): To ensure that data signals are not interfered by noise during long-distance transmission, it is necessary to consider cable length, impedance matching, signal attenuation, and reflection management. For example, conduct stack-up design and impedance calculation, and control differential equal length and impedance (for example, refer to Figure 10 the schematic diagram of differential equal-length line routing, stitched vias, and reasonable power division shown, where J2 on the adapter printed circuit board represents a jumper).

[0081] Power Layout management: Power lines and ground lines should be as close as possible to reduce noise and interference. Power lines should use low-impedance lines and have good filtering. For example, Figure 10 the gap between the power copper pour and the ground copper pour in

[0082] Thermal management: Considering the heat generation of the device, the heat dissipation path should be considered during layout to ensure good cooling. For example, the above structural design and Figure 10 copper pour design take into account the heat generation of the device.

[0083] Physical space: Reasonably arrange the positions of the plug-in modules and connectors to ensure sufficient spacing to prevent short circuits or electromagnetic interference. For example, Figure 10 The position of the connector takes into account the reasonable arrangement of physical space.

[0084] Grounding: Ensure a good grounding system to reduce noise and electromagnetic interference. At the same time, follow the manufacturer's specifications and industry standards. For example, Figure 10 The stitched ground hole design takes into account signal return and has a good grounding system.

[0085] Through the descriptions of the above embodiments, it can be seen that the hard disk adapter device of the technical solution of the present invention utilizes the longitudinal space (such as the thickness direction) of the original single hard disk slot by adding an adapter board, and two hard disks can be installed, that is, two 2.5-inch solid state drives can be installed on the interface of a single hard disk to increase the hard disk capacity. At the same time, the hard disk adapter device does not occupy extra space, and the installation and fixation method is compatible with 3.5-inch hard disks, facilitating subsequent hard disk expansion. At the same time, while expanding one hard disk into two hard disks, data can be written into the two hard disks simultaneously to provide redundant backup.

After the two 2.5-inch hard disks are installed in the hard disk adapter 10, the electrical connection between the two 2.5-inch hard disks and the hard disk adapter 10 can be realized. After that, the hard disk adapter 10 with the two 2.5-inch hard disks inserted can be inserted into the hard disk frame of the 3.5-inch hard disk in the chassis, and the hard disk adapter 10 can be fixed through the fixing holes in the hard disk frame and the fixing holes on the hard disk adapter 10, so that the electrical connection between the hard disk adapter 10 and the chassis can be realized. After the display corresponding to the chassis is turned on, the hard disk inserted in the hard disk adapter 10 can be displayed in the display, and then the hard disk inserted in the hard disk adapter 10 can be accessed through the display, such as copying the data in the display to the hard disk inserted in the hard disk adapter 10, so as to realize data storage in the hard disk inserted in the hard disk adapter 10.

[0089] Similarly, when only one 3.5-inch hard drive is needed, the 3.5-inch hard drive can be directly inserted into the hard drive frame of the 3.5-inch hard drive in the chassis, and the 3.5-inch hard drive can be fixed through the fixing holes in the hard drive frame and the fixing holes on the 3.5-inch hard drive. Then, the data in the display can be stored in the 3.5-inch hard drive according to the same storage process as above.

[0090] In this embodiment, the storage system includes a hard disk adapter and a chassis. The chassis is provided with a hard disk frame for fixing or connecting a 3.5-inch hard disk, and the hard disk frame is connected to the hard disk adapter. The hard disk adapter includes a shell with a cavity inside, a hard disk bracket and a transfer printed circuit board; the hard disk bracket includes two parallel supporting surfaces, the two supporting surfaces are connected and arranged in the cavity inside the shell, and form two staggered hard disk slots with the cavity; each hard disk slot is used to insert a 2.5-inch hard disk; the transfer printed circuit board is connected to one end of the shell, and the transfer printed circuit board includes two first connecting parts, the position of each first connecting part on the transfer printed circuit board corresponds to the position of each hard disk slot formed, and each first connecting part is used to be electrically connected to each 2.5-inch hard disk. Through the hard disk adapter, the installation method of a 3.5-inch hard disk can be compatible with the installation of two 2.5-inch hard disks, which is convenient for the subsequent expansion application of hard disks and flexible configuration of hard disks; at the same time, the longitudinal space of an original hard disk slot can be used to install two 2.5-inch hard disks to achieve redundant backup of data, that is, it can realize the redundant backup modification supporting a single mechanical hard disk slot.
