Embodiment Construction
[0046] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.
[0047] Such as figure 1 As shown, it is a structure diagram of an existing storage system 100, and the storage system 100 is a cluster composed of multiple storage arrays connected through a network 110, and is generally used as a data center. For the sake of brevity, only two storage arrays are shown in the figure, that is, the source storage array 120 and the target storage array 130. The source storage array 120 is the SSD from which data is migrated, and the target storage array 130 is the SSD from which data is migrated. SSD. The storage arrays communicate with each other through a communication protocol based on the RDMA protocol.
