Abstract: The present disclosure relates to data transmission methods, systems, and apparatuses. In one example method, a first device sends first information of a first data block to a second device. The second device searches, based on the first information, a first index for a second data block similar to the first data block, and sends second information of the second data block to the first device. The first device locally obtains, based on the second information, a reference block that is the same as the second data block, compresses a difference part of the first data block relative to the reference block to obtain first compressed information, and sends the first compressed information to the second device. The second device obtains the first data block based on the first compressed information and the second data block.

Abstract: A capacity adjustment method applied to a storage system includes: analyzing cold and hot attributes of data stored in the storage system, to obtain an amount of hot data and an amount of cold data in the data; determining, based on the amount of hot data and the amount of cold data, a capacity of a cache required by the storage system and a capacity of a persistent storage required by the storage system, where the cache required by the storage system comes from a first storage medium set, and the persistent storage required by the storage system comes from a second storage medium set; and adjusting, based on the capacity of the cache and the
