Description

Technical Field

[0001] This utility model relates to the field of cluster equipment technology, and in particular to a modular cluster equipment based on a single-board computer. Background Technology

[0002] Currently, computer-related education faces unprecedented challenges and opportunities. The rapid development of cloud-native technologies requires students majoring in networking to not only master traditional networking knowledge but also be familiar with network architecture and operations in a cloud environment. In particular, they can no longer limit their abilities to theoretical knowledge on paper but should deepen their understanding and improve their skills through practical operation.

[0003] However, current computer network practical teaching has many problems: the teaching content is too abstract and difficult to be specific, making it difficult for students to combine theoretical knowledge with practical operation; the experimental links lack connection and integration, making it difficult to form systematic practical ability; at the same time, the practical teaching equipment is neither high-end nor low-end, making it difficult for students to adapt to real work requirements.

[0004] The rise of single-board computers has brought new possibilities to network-based practical teaching. For example, building a cluster of multiple Raspberry Pi computers can provide a physical entity that is neither expensive nor unrealistic. It can simulate the operation of a cloud computing center, running necessary software systems, while also realistically showing students the appearance of real data centers, including computing nodes and their interconnections. However, existing Raspberry Pi clusters, as DIY (Do It Yourself) systems, are actually crude, temporary designs. A typical Raspberry Pi cluster is usually built with acrylic boards and copper pillars, resulting in a chaotic and unreliable structure in actual use. If students rely on such designs for experiments, they often need to invest a lot of effort in system deployment, maintenance, and debugging before the experiment, wasting practical experience and making teaching difficult. Furthermore, such systems are usually very fragile and easily damaged in real-world experimental environments. Finally, such designs severely lack flexibility; replacing nodes in a built system often requires complete disassembly or even redesign. Therefore, while this small system based on a single-board computer brings hope to cloud computing practical teaching, it is only an idea and cannot fully meet the needs of network practical teaching.

[0031] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following describes how this utility model is implemented in conjunction with specific embodiments.

[0032] Reference Figure 1 As shown, this utility model provides a modular cluster device based on a single-board computer, characterized in that it includes a cabinet 1, a blade rack 2, and a display module 3; the cabinet 1 is a rectangular vertical cabinet with hollow structures on all four sides; the blade rack 2 is installed inside the cabinet 1, and multiple blade positions are formed by multiple horizontal partitions inside the blade rack 2; each blade position can be configured with one blade plate, and the blade plate can be installed in or removed from the blade position by plugging and unplugging; the display module 3 is installed at the top center of the cabinet 1, and the display module 3 can be connected to multiple blade plates through connecting cables.

[0033] Understandably, in cluster mode, all blade boards can be connected to share resources and serve the same user group. Introducing new blade boards can improve overall performance. Because each blade board is hot-swappable, the system can be easily replaced, minimizing maintenance time.

[0034] Preferably, each blade position is equipped with a dedicated power supply and switching mechanism, which can independently control the blade plate on each blade position.

[0035] Preferably, the display module 3 includes a display screen, a back panel, and an opening / closing mechanism. The back panel is fixedly installed on the back of the display screen, and the opening / closing mechanism allows the display screen and the back panel to switch between a closed and an open state. In the closed state, the display module 3 is horizontal, the back panel serves as the top cover of the cabinet 1, and the display screen faces downwards and is hidden. When switching from the closed state to the open state, the display screen and the back panel are flipped and slid together, causing the display screen to open outwards. The display screen can be a touch screen to display relevant information about each blade plate and facilitate user operation and management of the blade plates.

[0036] Further reference Figure 2 As shown, preferably, the modular cluster based on a single-board computer also includes a ventilation and heat dissipation system 4 disposed on one side of the cabinet 1.
