Abstract

The embodiment of the invention provides a power supply method and equipment, an RAID card and a main board, and relates to the field of storage. The power supply method and equipment, the RAID card and the main board aim to achieve long-time power down protection and reduce the cost of the power down protection and occupied server space. The RAID card comprises a memorizer and a power supply device, wherein the memorizer is used for caching data, and the power supply device is used for obtaining wireless electric signals transmitted by power source equipment, converting the wireless electric signals into electric power, and supplying power for the memorizer through the electric power. The embodiment of the method is applied to achieving the power down protection for the memorizer.

Description

Technical field [0001] The present invention relates to the storage field, in particular to a power supply method and equipment, a RAID card and a motherboard. Background technique [0002] RAID (Redundant Array of Independent Disks, Redundant Array of Independent Disks) is a combination of multiple independent hard disks (physical hard disks) in different ways to form a hard disk group (logical hard disk), thereby providing higher storage than a single hard disk Performance technology. [0003] Existing RAID cards include memory, which is used to cache data. However, since the memory is generally a volatile storage medium, once the server is accidentally powered off, the data in the memory will be lost. Therefore, in order to prevent the server The data in the memory is lost due to accidental power failure. In the prior art, a battery is usually used to achieve power failure protection. Specifically, the battery is connected to the RAID card through a cable to achieve power suppl...
