Description

Technical Field

[0001] This utility model relates to the field of NAS storage device technology, and more specifically, to a NAS storage device suitable for high-speed AI computing. Background Technology

[0002] Traditional NAS storage devices rely on ordinary file management systems for file storage and organization. Identification and categorization require manual operation, which is inefficient and cannot be quickly customized to each user's habits. AI, as an emerging technology, can deploy local image and text search and analysis functions on NAS storage devices through various large models. This accelerates the speed of recognition and text dialogue output, enabling rapid organization and sorting, reducing user waiting time, and allowing for quick customization based on each user's habits.

[0003] However, the aforementioned AI functions require hardware support in two aspects: first, AI computation requires substantial local data storage space, and the storage device needs to have a fast transfer speed to provide a good user experience; second, AI computation requires a high-performance dedicated graphics card to maintain normal operation. Existing NAS storage devices lack both of these features, therefore they are unsuitable for high-speed AI computation. Utility Model Content

[0004] The purpose of this invention is to provide a NAS storage device suitable for high-speed AI computing. This NAS device features an external storage expansion shell specifically designed to expand the storage space of the local NAS, meeting the storage and transmission speed requirements of AI computing. At the same time, the NAS device is designed with a dedicated OCulink interface for connecting external graphics card expansion dock accessories to meet the computing power support of AI computing. It is suitable for high-speed local AI computing and improves the user's data organization and usage experience.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A NAS storage device suitable for high-speed AI computing includes a NAS host device housing and a storage expansion device housing. The storage expansion device housing has an upper cover plate and a bottom fixing plate on its upper and lower sides, respectively. An intermediate partition plate is connected between the upper cover plate and the bottom fixing plate by studs. A hard drive expansion main circuit board is fixed to the rear of the intermediate partition plate by screws. The hard drive expansion main circuit board has four U.2 hard drive slots in front, and U.2 hard drive brackets are connected to the front of the U.2 hard drive slots. Two symmetrical fans are located behind the U.2 hard drive brackets. The storage expansion device housing has symmetrical ventilation holes on both sides and several cutouts on the front and rear sides. An interactive display screen is embedded in the cutout on the front right side. The interactive display screen is connected to a display screen main control board, and the display screen main control board is fixed to the upper right side of the intermediate partition plate by screws.

[0007] As a further optimization of this solution, a heat sink is provided on the right side of the main circuit board for hard drive expansion, and a PCIE 5.0 x8 interface is provided on the lower right side of the main circuit board for hard drive expansion. The PCIE 5.0 x8 interface is inserted into the corresponding slot on the motherboard inside the NAS host device casing.

[0008] As a further optimization of this solution, the NAS host device casing is connected and fixed to the motherboard through the bottom shell via long screws around the perimeter. Studs are provided around the perimeter between the motherboard and the bottom shell. Six M.2 hard drive slots are arranged side-by-side below the motherboard. The center area of ​​the bottom shell is hollowed out, and a bottom hard drive quick-release plate is fixed below the hollowed-out area with screws. The back of the motherboard controller is connected to the base plate above the controller via a heat dissipation module. A thermally conductive copper fin is provided on the lower surface of the base plate at the position corresponding to the controller. A heat pipe is fixed to the upper surface of the base plate with spring screws. A heat dissipation fin is fixed to the left side of the heat pipe, and a fan is fixed to the right side of the heat dissipation fin.

[0009] As a further optimization of this solution, anti-slip rubber strips are bonded to the four corners of the bottom shell, and a WIFI antenna baffle is provided on the rear side of the NAS host device housing.

[0010] As a further optimization of this solution, the back of the motherboard is also provided with an M.2 WiFi module slot, and the front of the motherboard is provided with a DC power port, an RJ4510G network port, an HDMI & DP output port, an OC ulink interface, a Thunderbolt 4 interface, a headphone / microphone jack, a USB 3.2 interface and a reset button arranged in sequence on one side.

[0011] Compared with existing technologies, the beneficial effects of this utility model are as follows:

[0012] 1. High-capacity, high-speed storage: This solution features six M.2 solid-state drive slots on the back of the motherboard, accommodating six 2280 M.2 hard drives. The upper storage expansion module allows for four U.2 hard drive bays with active cooling. The U.2 hard drive motherboard uses the PCIe 5.0 x8 interface for data transfer. The four hard drives share the 31.5GB / s port bandwidth evenly through expansion chips, ensuring each drive meets the PCIe 4.0 x4 bandwidth requirement. The M.2 slots on the motherboard support PCIe 4.0 x4, with a theoretical port transfer speed of 7.87GB / s. This product offers the advantage of large-capacity storage using U.2 hard drives while also providing good cost-effectiveness with M.2 hard drives. Since both are flash memory drives, their sequential read / write and small file transfer speeds are faster than existing technologies, while power consumption and operating noise are significantly lower than traditional mechanical hard drives.

[0013] 2. High-speed data transmission capability: This solution uses dual 10G RJ45 ports for data transmission, with each port achieving a transmission rate of up to 10Gbps. The RJ45 ports can use port aggregation technology to combine the two ports to a total speed of 20Gbps. It also includes two Thunderbolt 4 interfaces with a speed of 40Gbps, fully meeting the high-speed access and data transmission needs of M.2 and U.2 hard drives. Furthermore, it is equipped with a Wi-Fi module supporting 2.4Gbps wireless transmission and Bluetooth connectivity, satisfying various storage, network access, and data transfer requirements.

[0014] 3. A highly efficient and stable heat dissipation module ensures system stability during prolonged use. The heat dissipation module employs active cooling to lower the temperature of the main core. This device uses a high-power x86 processor with a thermal design power of 65W. To cope with this 65W thermal power and prevent performance degradation or system crashes due to high temperatures, a pure copper heat dissipation module is used. The module works as follows: first, the heat from the CPU is conducted from the copper base above the core through heat pipes to the copper fins. A centrifugal turbine fan draws in cool air from the side and top air intake grilles and blows it onto the fins, transferring heat out of the device and maintaining its operating temperature. Thermally conductive silicone pads are attached to the copper base of the heat dissipation module, covering the power MOSFETs and optical port chips, while also providing auxiliary cooling for the MOSFETs and network card chips, reducing component temperatures and improving device stability.

[0015] 4. Suitable for high-speed AI computing: The NAS device in this solution is specially designed with an external storage expansion shell to expand the local NAS storage space and meet the storage and transmission speed requirements of AI computing. At the same time, the NAS device is designed with a dedicated OCulink interface for connecting external graphics card expansion dock accessories to meet the computing power support of AI computing. This can significantly increase the machine's AI computing power, meet the computing power requirements for localized AI deployment, and improve the user's data organization and usage experience.

[0016] 5. Easy-to-use visual UI: The interactive display screen structure of this solution can integrate commonly used functions, such as network port speed display, IP display and modification, port display, hard disk storage speed and available capacity display, hard disk temperature and health display, system version and update display. By integrating commonly used functions into the front display screen, users can operate and obtain some functional information of this product without entering the WEB UI interface of the NAS device system.

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description, in conjunction with specific illustrations, further elaborates on this utility model.

[0023] To address the issues that existing AI computing requires a large amount of local data storage space and fast data transfer speeds to provide a good user experience, as well as the need for high-performance dedicated graphics cards to maintain normal operation, current NAS storage devices do not meet either of these requirements and are therefore unsuitable for high-speed AI computing.

[0024] like Figure 1 and Figure 2 As shown, this application includes a NAS host device housing 2 and a storage expansion device housing 1. The storage expansion device housing 1 has an upper cover plate 3 and a bottom fixing plate 14 on the upper and lower sides, respectively. The upper cover plate 3 and the bottom fixing plate 14 are connected by a middle layer partition 10 through studs 8. The hard disk expansion main circuit board 11 is fixed to the back of the middle layer partition 10 by screws 7. The hard disk expansion main circuit board 11 has four U.2 hard disk slots 12 in front and a U.2 hard disk bracket 5 connected to the front of the U.2 hard disk slots 12. Two symmetrical fans 6 are located behind the U.2 hard disk bracket 5. The storage expansion device housing 1 has symmetrical ventilation holes on both sides and several hollow slots on the front and back sides. An interactive display screen 4 is embedded in the hollow slot on the front right side. The interactive display screen 4 is connected to the display screen main control board 9 and the display screen main control board 9 is fixed to the right side of the upper surface of the middle layer partition 10 by screws 7.

[0025] The hard drive expansion main circuit board 11 has a heat sink 13 on the right side, and a PCIE 5.0 X8 interface 37 is located on the lower right side of the hard drive expansion main circuit board 11. It is inserted into the corresponding slot of the motherboard 21 inside the NAS host device housing 2 through the PCIE 5.0 X8 interface 37.

[0026] like Figure 3 As shown, the NAS host device housing 2 is connected and fixed to the motherboard 21 through the bottom shell 23 via long screws 25 around the perimeter. There are studs around the motherboard 21 and the bottom shell 23. There are six M.2 hard drive slots 27 arranged side by side below the motherboard 21. The center area of ​​the bottom shell 23 is hollowed out, and the bottom hard drive quick release plate 24 is fixed to the bottom of the hollowed-out area by screws 7. The back of the controller of the motherboard 21 is connected to the base plate 17 above the controller of the motherboard 21 via a heat dissipation module and a back plate 22. There are heat-conducting copper plates 19 on the lower surface of the base plate 17 corresponding to the controller. The heat pipe 18 is fixed to the upper surface of the base plate 17 by spring screws 16. The heat dissipation fins 15 are fixed to the left side of the heat pipe 18, and the fan 6 is fixed to the right side of the heat dissipation fins 15. Anti-slip rubber strips 26 are bonded to the four corners of the bottom shell 23. There is a WIFI antenna baffle 20 on the rear side of the NAS host device housing 2.

[0027] like Figure 4 As shown, the back of the motherboard 21 also has an M.2 WiFi module slot 28, and the front of the motherboard 21 has a DC power port 29, an RJ45 10G network port 30, an HDMI & DP output port 31, an OCulink interface 32, a Thunderbolt 4 interface 33, a headphone / microphone jack 34, a USB 3.2 interface 35, and a reset button 36 arranged in sequence.

[0028] Specifically, the thermally conductive copper plate 19 contacts the copper base on the core surface, and thermal grease is used to fill the area below the core contact surface. A 4-pin connector extends from the outside of the fan 6, connecting to the fan control interface on the motherboard 21. The back of the motherboard 21 has six M.2 hard drive slots 27 for connecting external M.2 hard drives. An M.2 Wi-Fi module slot is located below the first M.2 hard drive slot 27; inserting a wireless network card allows for Wi-Fi and Bluetooth connectivity. The NAS host housing 2 and the storage expansion housing 1 have large exhaust grilles matching the exhaust vents of the heat dissipation module, with fine holes around the perimeter for internal airflow. The rear has a full-hole air intake, allowing cool air to enter the machine through the air intake vents around the housing and be drawn in by the centrifugal fan 6 to cool the main core. The upper part uses independent dual fans 6 to draw cool air from the outside into the chassis, actively cooling the U.2 hard drives and reducing their operating temperature.

[0029] The device utilizes six M.2 drive bays 27 to simultaneously connect six solid-state drives (SSDs). The storage expansion device casing 1 can accommodate four U.2 drive bays. Combined with a PCIe 5.0 x8 interface 37 for data transfer, it meets the storage and transmission speed requirements of AI computing. Simultaneously, a dedicated OCulink interface 32 is designed for connecting external graphics card expansion dock accessories, providing sufficient computing power for AI operations. This addresses issues in existing NAS products on the market, such as insufficient processor computing power leading to a lack of local AI data analysis library deployment capabilities, slow file storage speeds, limited storage expansion slots, excessive size, poor heat dissipation, and low data transmission bandwidth.
