specific Embodiment

[0113] As a specific embodiment of the storage system data protection method provided by the present invention, it includes the following steps:

[0114] Step S100, when data is written into the solid-state storage module, control the data to perform RAID calculation to generate verification block data.

[0115] Step S200, detect the amount of data. When the amount of data is greater than or equal to the stripe width of the solid-state storage module, execute step S300; when the amount of data is smaller than the stripe width of the solid-state storage module, execute step S400.

[0116] Step S300, controlling the data of the verification block to be written into the solid-state storage module.

[0117] Step S400, controlling the data of the verification block to be written into the backup module.

[0118] Here, it should be noted that the solid state storage module can be a solid state disk, and the backup module can be a hot spare disk. In the following embodiments, the sol...

Abstract

The invention discloses a storage system and a data protection method thereof, wherein the storage system includes a plurality of solid-state storage modules, a detection module, a control module and a backup module, wherein: a plurality of solid-state storage modules form a RAID for data writing into a solid-state During the storage module, RAID calculation is performed on the data to generate check block data; the detection module is used to detect the data volume of the data; the control module includes a first control unit and a second control unit, wherein: the first control unit is used for When the amount of data is greater than or equal to the stripe width of the solid-state storage module, the control verification block data is written into the solid-state storage module; the second control unit is used to control the verification when the amount of data is less than the stripe width Block data is written to the backup module. By adding a backup module, the frequent writing of the verification block data is concentrated to the backup module, which reduces unnecessary loss of the solid-state storage module and maintains the life of the solid-state storage module.

Description

technical field [0001] The invention relates to the field of computer storage systems, in particular to a storage system and a data protection method thereof. Background technique [0002] With the appearance of solid state disks (Solid State Drives, solid state disks), the performance of computer storage systems has been greatly improved, and by combining computer storage systems with RAID (Redundant Array of Independent Disks, redundant array of independent disks) technology, The reliability and security of data stored in the computer storage system are effectively improved. [0003] However, by combining the storage system with the RAID technology, since the check blocks calculated by the RAID need to be written frequently, this makes the solid-state storage modules (such as: solid-state disks) in the computer storage system store the check blocks in the RAID. Blocks have many times more writes than data blocks, shortening the life of solid-state memory modules. [0004...
