摘要： Embodiments of the present invention provide an array controller, including a communications interface and a processor. The communications interface is configured to communicate with a solid state disk. The processor is configured to receive information about a logical block sent by the solid state disk, where the information about the logical block includes a size of the logical block and indication information of the logical block, and the logical block includes one or more blocks. The processor is further configured to send multiple write data requests to the solid state disk, where each write data request carries target data, each write data request is used to instruct the solid state disk to write the target data into the logical block indicated by the indication information of the logical block, and a sum of lengths of the target data carried in the multiple write data requests is equal to the size of the logical block. The logical block may be filled after the solid state disk writes each piece of target data to the logical block, which can reduce write amplification when the solid state disk performs a garbage collection operation.
摘要翻译：本发明的实施例提供了一种阵列控制器，包括通信接口和处理器。通信接口配置为与固态磁盘进行通信。处理器被配置为接收关于由固态盘发送的逻辑块的信息，其中关于逻辑块的信息包括逻辑块的大小和逻辑块的指示信息，并且逻辑块包括一个或多个块。处理器还用于向固态硬盘发送多个写入数据请求，每个写入数据请求中携带目标数据，每个写入数据请求用于指示固态硬盘将目标数据写入该固态硬盘指示的逻辑块中所述逻辑块的指示信息，所述多个写入数据请求中携带的所述目标数据的长度之和等于所述逻辑块的大小。在固态磁盘将每个目标数据写入逻辑块之后可以填充逻辑块，这可以减少固态磁盘执行垃圾收集操作时的写入放大。

摘要： Embodiments of the present invention provide a data replication method and a storage system. The method is applied to a storage system including at least a first storage device and a second storage device. The method includes: determining, by a first storage system, replication information, where the replication information is used to indicate data that needs to be replicated by the first storage system to a second storage system in a current replication task; determining, by the first storage system, first replication sub-information and second replication sub-information according to the replication information; replicating, by the first storage device to the second storage system according to the first replication sub-information, data that needs to be replicated by the first storage device to the second storage system; and replicating, by the second storage device to the second storage system according to the second replication sub-information, data that needs to be replicated by the second storage device to the second storage system. According to the data replication method, efficiency of replication performed between the first storage system and the second storage system can be improved.

摘要： 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.
