Description

Technical Field

[0001] This invention relates to the field of server chassis technology, specifically to a horizontally expandable modular network storage server chassis. Background Technology

[0002] The biggest feature of modular network storage server chassis is that it breaks down computing, storage, networking, power, and cooling resources into smaller, more manageable components. Modular design allows businesses to flexibly configure and expand hardware like building blocks, based on their actual business needs. You can add, remove, or upgrade server nodes, storage modules, and network switching modules at any time without replacing the entire chassis. This on-demand customization capability easily adapts to various workloads, from small offices to large-scale data centers. Using modular chassis effectively avoids the large upfront capital expenditures of traditional data centers. Businesses can make incremental investments, gradually increasing computing or storage resources as their business grows, avoiding resource waste caused by initial over-purchasing. Modular chassis typically support redundant design in power supply, cooling fans, and network architecture, meaning that even if one component fails, the system can continue to operate normally.

[0003] However, currently available modular network storage server chassis have several significant drawbacks: First, the physical layer hardware interconnect mechanism only supports vertical expansion, preventing the system from linearly and elastically scaling storage capacity and computing performance by adding nodes, severely restricting the scalability deployment requirements of data centers. Second, the cooling system uses an open airflow design, lacking a closed structure, and the cooling channels cannot be dynamically adjusted or closed according to the load, leading to chaotic airflow and localized hotspot accumulation, which will significantly increase hardware failure rates and shorten equipment lifespan over the long term. Third, the mechanical structure design is flawed; the server fixing modules only use single-point suspension fasteners and lack redundant anti-vibration fixing mechanisms and dynamic balance adjustment devices, making them prone to displacement or loosening under high-density loads or physical vibration environments, failing to ensure long-term mechanical stability and reliability. Therefore, designing a horizontally expandable modular network storage server chassis is essential. Summary of the Invention

[0004] The purpose of this invention is to provide a horizontally scalable modular network storage server chassis to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a horizontally expandable modular network storage server chassis, comprising a chassis shell, a heat dissipation channel, and a management controller. An expansion connection interface is fixedly connected to the chassis shell. A fixing block is fixedly connected to the chassis shell. One end of a spring is fixedly connected to a groove in the fixing block, and a limiting plate is fixedly connected to the other end of the spring. A snap-fit ​​block is fixedly connected to the limiting plate, and a counterweight is fixedly connected to the snap-fit ​​block. The snap-fit ​​block snaps into a slot in a connecting joint. The connecting joint is fixedly connected to the chassis shell. The expansion connection interface is fixedly connected to the management controller. A first snap-fit ​​plate is snapped onto the management controller. The first snap-fit ​​plate is fixedly connected to a fixing device. A second snap-fit ​​plate is fixedly connected to the fixing device. A fixing bolt is provided on the fixing device. An expansion port is provided on the management controller.

[0006] As a further technical solution of the present invention, the second snap-fit ​​plate is snapped into the groove of the partition plate, and a fixing bolt is provided in the hole of the partition plate.

[0007] As a further technical solution of the present invention, a protective door is rotatably connected to the chassis shell, a handle is fixedly connected to the protective door, and a heat dissipation groove is provided on the chassis shell.

[0008] As a further technical solution of the present invention, a support base is fixedly connected to the bottom of the chassis housing, and a top cover is fixedly connected to the top of the chassis housing.

[0009] As a further technical solution of the present invention, the top cover is provided with a heat dissipation channel, and a fixing plate is fixedly connected to the top cover.

[0010] As a further technical solution of the present invention, a sealing plate is slidably connected to the fixing plate, and a connecting block is fixedly connected to the sealing plate.

[0011] As a further technical solution of the present invention, a second fixed flange is fixedly connected to the connecting block, and a driving cylinder is fixedly connected to the second fixed flange.

[0012] As a further technical solution of the present invention, a first fixed flange is fixedly connected to the drive cylinder, and the first fixed flange is fixedly connected to the chassis housing.

[0013] As a further technical solution of the present invention, a threaded shaft is rotatably connected to the chassis housing, a rotating handle is fixedly connected to the threaded shaft, a square sleeve is threadedly connected to the threaded shaft, and a tightening plate is fixedly connected to the square sleeve.

[0014] As a further technical solution of the present invention, the tightening plate is in close contact with the storage device, and the storage device is in close contact with the casing.

[0015] Compared with existing technologies, the advantages of this invention are: a single chassis can serve as a basic unit, physically connecting with adjacent chassis through expansion connection interfaces to form a multi-chassis cluster, supporting up to 10 chassis cascaded, achieving linear expansion of storage capacity and computing nodes; computing racks and storage racks communicate directly through a high-speed backplane; when spanning multiple chassis, a dedicated interconnect module ensures transparent data paths between modules, maintaining low latency and high bandwidth access even after expansion; physical locking is achieved by a fixing block engaging with the connection connector, and a counterweight applying gravity, causing the engaging block to engage with the groove of the fixing block; and storage capacity can be increased by adding nodes. The linear elastic scaling of computing performance enhances the scalability of data center deployments. The drive cylinder moves the enclosed plate, which in turn adjusts the opening and closing of the heat dissipation channels, preventing chaotic airflow and localized hotspot accumulation, reducing hardware failure rates and extending equipment lifespan. Rotating the handle and threaded shaft moves the tightening plate and square sleeve, ultimately pressing the storage device. The first and second snap-fit ​​plates engage the management controller, which is then secured with fixing bolts. This prevents displacement or loosening under high-density loads or physical vibrations, ensuring long-term mechanical stability and reliability. Attached Figure Description
