  • Patent number: 12197338
    Abstract: Techniques for data processing involve: performing, according to a determination that a programmable circuit receives user-written data, data feature detection by the programmable circuit on a first part of the user-written data. Such techniques further involve: replacing, in response to the first part matching a predetermined data feature, the first part by the programmable circuit with a data representation corresponding to the predetermined data feature. In addition, such techniques involve: writing the data representation to a cache region of a storage system. Accordingly, such techniques can save cache resources of a storage system and can save CPU of the storage system, thus avoiding the latency due to data feature detection and improving the user experience.

  • Publication number: 20240354025
    Abstract: Techniques for data migration involve obtaining feature data of a plurality of logical storage units in a first storage device, the feature data comprising deduplication information of each of the plurality of logical storage units. Such techniques further involve determining, based on the feature data, a set of similarity values between the plurality of logical storage units. Such techniques further involve migrating a logical storage unit having a similarity value higher than a similarity threshold among the plurality of logical storage units from the first storage device to a second storage device different from the first storage device.

  • Publication number: 20240184471
    Abstract: Techniques for data migration involve obtaining, at an edge device, a bitmap in a local memory, the bitmap including a plurality of parameter values. The techniques further involve updating, in response to a data block being written or read, a data heat value of the data block based on the bitmap. The techniques further involve migrating the data block between the edge device and a cloud device based on the updated data heat value. Accordingly, there is a solution for migrating data blocks between an edge device and a cloud device, such that data with a high data heat value is stored at the edge device and data with a low data heat value is stored at the cloud device, thereby improving the performance of a storage system.
