Abstract:
A storage system and a system garbage collection method are provided. The storage system includes a first controller, a second controller, and a solid state disk. The first controller or the second controller manages storage space of the solid state disk in a unit of a segment. The first controller is configured to perform system garbage collection on multiple segments of segments managed by the first controller. The second controller is configured to: when the first controller performs system garbage collection, perform system garbage collection on multiple segments of segments managed by the second controller. The multiple segments of the segments managed by the first controller and the multiple segments of the segments managed by the second controller are allocated within a same time period. Therefore, a quantity of times of write amplification in the solid state disk can be reduced.

Claim (Index 6):
The storage system according to  claim 1 , wherein\n the first controller is configured to send, to the solid state disk, a source logical address of valid data comprised in each of the multiple segments managed by the first controller; allocate a destination logical address to the valid data; send the destination logical address to the solid state disk to instruct the solid state disk to copy the valid data from the source logical address into the destination logical address; and send an unmap command to the solid state disk to instruct the solid state disk to delete a correspondence between a logical address and an actual address of each segment, wherein the correspondence is stored by the solid state disk, and wherein the unmap command comprises a logical address range of each of the multiple segments managed by the first controller.
