A garbage collection technology for a storage medium that includes a plurality of blocks, where each storage unit has a collection parameter related to data in one of the blocks, and where each block includes a plurality of pages. A group of blocks is selected from the plurality of blocks based on the collection parameter. A difference between values of collection parameters of any two blocks in the group of blocks is not greater than a preset value. Data in a first valid page and a second valid page in the group of blocks is replicated to a same destination block, to facilitate garbage collection.

Garbage collection method for storage medium, storage medium, and program product

In a distributed storage system, a first storage node receives a first data read request for reading first data. The first data request includes a first address of the first data. The first storage node determines that the first data are stored in a first storage device included in the first storage node based on the first address. Based on the determination, the first storage node checks whether the first storage device is in a trusted access state. Further, the first storage node obtains the first data when the first storage device is in the trusted access state.

A maritime green human settlement system and a modularized construction method therefor. The maritime green human settlement system comprises at least one floor unit (), solar photovoltaic plates (), and a deck (). The floor unit () is mounted on the deck (). The solar photovoltaic plates () are mounted on the top surface of the highest floor unit (). Each floor unit () comprises at least one room and indoor furniture. The room and the indoor furniture are formed by means of dislocated splicing of at least three modules (), and at least one recessed portion (H) is formed at splicing positions. The maritime green human settlement system can form multiple indoor-outdoor spatial relationships; the flexibility is high, the construction period is short, and costs are low.
