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 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 computer system and a method are provided for accessing a peripheral component interconnect express (PCIe) endpoint device. The computer system includes a processor, a PCIe bus, and an access proxy. The access proxy connects to the processor and the PCIe endpoint device; the processor acquires an operation instruction, where the operation instruction instructs the processor to access the PCIe endpoint device through the access proxy, and send an access request to the access proxy according to the operation instruction; and the access proxy sends a response message of the access request to the processor after receiving the access request sent by the processor. Because the processor does not directly access the PCIe endpoint device to be accessed but completes access through the access proxy, thereby avoiding a machine check exception (MCE) reset for the processor.
