Abstract: A memory access apparatus includes a read-write module and a processing module. The read-write module is configured to store an error detecting code in an (M+2)th DRAM in the memory row, and store the error correcting code in a Zth DRAM in the memory row, where Z is a positive integer, 1≦Z≦(M+1), and error correcting codes in consecutive (M+1) memory rows are stored in different DRAMs. The processing module is configured to calculate one group of error detecting code for each SCBC in a memory row, and calculate one group of error correcting code for all SCBCs in a memory row.

Abstract: A method for migrating data by a source network interface card includes: receiving a first migration instruction; sending a read instruction to the source SSD when receiving the first migration instruction, where the read instruction is used to instruct the source SSD to read the to-be-migrated data into the source migration cache; and sending a second migration instruction to a target intelligent network interface card of the target storage array after the to-be-migrated data is read from the source SSD, where the second migration instruction is used to instruct the target intelligent network interface card to migrate the to-be-migrated data in the source migration cache to the target storage array.

Abstract: A SAS system includes an SAS controller, a first expansion card, a second expansion card, and a third expansion card. The first expansion card includes a first port and a second port. The second expansion card and the third expansion card establish a communication connection to the SAS controller by using the first expansion card. The first expansion card establishes a communication connection to the second expansion card through the first port. The first expansion card establishes a communication connection to the third expansion card through the second port. The second expansion card is connected to the third expansion card.

Abstract: A host of a storage system is coupled to multiple SSDs. Each SSD is configured with a migration cache, and each SSD corresponds to one piece of access information. The host obtains migration data information of to-be-migrated data in a source SSD, determines a target SSD, and sends a read instruction carrying information about to-be-migrated data and the target SSD to the source SSD. The source SSD reads a data block according to the read instruction from a flash memory of the source SSD into a migration cache of the target SSD. After a read instruction is completed by the SSD, the host sends a write instruction to the target SSD to instruct the target SSD to write the data block in the cache of the target SSD to a flash memory of the target SSD.

Abstract: A first storage node communicates with at least one second storage node. A physical disk included in the at least one second storage node is mapped as a virtual disk of the first storage node. The method may include: receiving a first write request, where the first write request carries first to-be-written data; striping the first to-be-written data to obtain striped data, and writing the striped data to a physical disk and/or the virtual disk of the first storage node; and recording a write location of the striped data. For example, the technical solution may be applied to a storage system that includes an NVMe SSD.
