STORAGE SYSTEM, STORAGE MANAGEMENT DEVICE, STORAGE DEVICE, HYBRID STORAGE DEVICE, AND STORAGE MANAGEMENT METHOD

摘要

A storage system, a storage management device, a storage device, a hybrid storage device, and a storage management method. The storage system comprises the storage device and a manager. The storage device comprises multiple physical blocks. The manager is used for receiving a data write request and determining a logical block for a to be written data page (S1001); recording a logical address of the to be written data page into the logical block (S1002); and transmitting a data write instruction to a solid-state disk (SSD), where the data write instruction carries the to be written data page and logical space information of the to be written data page (S1003). The data write instruction is received, information of the logical block is acquired on the basis of the logical space information of the to be written data page in the data write instruction, and a physical block corresponding to the logical block is determined on the basis of the information of the logical block (S1004); and the to be written data page is written into the physical block corresponding to the logical block (S1005). The method reduces work for a flash translation layer of the storage device, thus increasing the performance of the storage device.
