Problems solved by technology
General designers will use dedicated chips for each voltage when performing hot-swap related designs. This method does not consider the actual use of the load circuit for power supply, nor does it fully utilize the function of the circuit protected by the hot-swap circuit. , and there is no price advantage; so this method is not a cost-effective design solution

The invention provides a system and a method for realizing hot plug of equipment. The system comprises a power module, an equipment backboard and an expansion board, wherein the power module provides a plurality of different power line groups for the equipment backboard; the equipment backboard transmits the plurality of power line groups to the expansion board through a connector; moreover, the expansion board sets corresponding hot plug modules according to the plurality of power line groups transmitted by the connector. In the invention, on the basis of taking a hot plug function and application between the expansion board and the equipment backboard into full consideration, and aiming at various voltages, corresponding hot plug circuits are arranged; and on the premise of greatly reducing the cost of a hot plug protection circuit among equipment board cards, the function of the equipment is more completed, so the cost performance of the equipment is promoted.
Description
technical field [0001] The invention relates to the design of a hot swapping circuit of equipment, in particular to a system and method for realizing hot swapping of equipment. Background technique [0002] At present, customers' demands for storage products have become more and more diversified, and products with high performance, strong scalability and ease of use have been proposed. For example, JBOD (Just Bundle Of Disks, also known as disk cluster) is an important storage device in the storage field. By logically connecting several physical disks together, a logical disk with a large capacity is provided. . JBOD storage devices have very strong scalability, and at the same time, they are not inferior in access performance. [0003] At present, when designing products such as JBOD, it is necessary to consider that the product must have high scalability and high reliability. In order to meet such requirements, it is usually required that the expansion board of the prod...
