Problems solved by technology

[0003] Because the backup power module in the above prior art is located in the closed housing of the storage module, the backup power module will be limited by the space of the storage module, resulting in a low backup capacity of the backup power module; and the backup power module is more sensitive to the ambient temperature, and the backup power module The power module is located inside the storage module, and the heat dissipation is limited to a certain extent, resulting in a higher probability of failure of the backup power module after long-term operation
Therefore, the risk of data loss is greater by adopting the above-mentioned storage modules (such as SSD discs) of the prior art

Abstract

The embodiment of the invention provides a storage device and a power supply method for the storage device. The storage device comprises a storage module and a standby power module arranged outside the storage module, wherein when the storage module is powered off, the standby power module supplies power to the storage module so as to write data in a cache into the storage module; the storage module is connected with the standby power module through a first connector; or if the storage device also comprises a switching card, the standby power module is arranged on the switching card; and the switching card is connected with the storage module through a second connector. By adopting the technical scheme of the embodiment of the invention, the data loss risk is low and the safety of the data can be improved effectively.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of storage, and in particular, to a storage device and a power supply method for the storage device. Background technique [0002] In an existing storage system, several storage modules are used to store data, and each storage module (such as a solid state drive (Solid State Drive; SSD for short) disk) serves as a closed casing. There is a backup power module inside the storage module, which is used to provide power for the corresponding storage module when the storage system is powered off, so as to support the controller inside the storage module to write the data in the cache into the storage module to avoid data loss . [0003] Because the backup power module in the above prior art is located in the closed housing of the storage module, the backup power module will be limited by the space of the storage module, resulting in a low backup capacity of the backup power module; and the ...
