Abstract

The embodiment of the invention discloses a mirror caching method. The mirror caching method comprises the following steps: simultaneously storing cache data into a local-end first cache region and sending data information to an opposite-end first cache region; copying cache data information by virtue of a mirror layer when data is brushed from the local-end first cache region to a local-end second cache region; and finally storing the two same cache data information into the local-end second cache region, and sending the corresponding cache data information to an opposite-end second cache region, so as to finish the mirror caching. According to the technical scheme, an existing cache region is divided into two layers of cache regions so as to store mirror data, and the copying is repeatedly carried out, so that the data security and stability are improved; besides, by mirroring a cache data address, the damage or loss of the data is further prevented, so that the cache performance is improved, and the reliability of a system is guaranteed. Beside, the embodiment of the invention further provides a corresponding implementation device. By utilizing the corresponding implementation device, the method has relatively high practicability; and the device has the corresponding advantages.

Description

technical field [0001] The invention relates to the technical field of computer storage, in particular to a method and device for caching mirror images. Background technique [0002] With the rapid development of computer technology and the advent of the era of big data, more and more digital and network technologies have been used in daily life, scientific research, and corporate business, resulting in explosive growth of data. In the face of large-scale data applications, the requirements for the security and stability of data storage technology are getting higher and higher, and cache mirroring plays an important role in the stability and consistency of data. [0003] Mirroring is continuous, real-time copying (replication) of data. The cache mirroring technology is to solve the problem of data loss in the cache that may occur when the disk array controller fails. Because the write operation is to update or create the disk data, the data of the write operation first act...
