摘要： A method for adaptive concurrency for write persistence in a storage system, performed by the storage system, is provided. The method includes selecting a write process from among a plurality of write processes, responsive to receiving a write request for writing data into the storage system, and writing the data into the storage system in accordance with the selected write process. One of the plurality of write processes includes transferring the data into the storage system, locking an inode associated with file information of the data in memory, updating the file information in the inode while the inode is locked, committing the data while the inode is locked, and unlocking the inode.

摘要： A storage system with storage drives and a processing device establishes resiliency groups of storage system resources. The storage system determines an explicit trade-off between data survivability over resource failures and data capacity efficiency, for the resiliency groups. Responsive to adding at least one storage drive, the storage system establishes re-formed resiliency groups according to the explicit trade-off, without decreasing data survivability. The storage system may bias to have more and narrower resiliency groups to increase mean time to data loss.

摘要： A storage system performs garbage collection, with data compression, in storage memory. The system obtains hash results from data segments. The system determines similarity of content of data segments, based on the hash results. The system performs data compression of live data of two or more data segments that have similarity of content meeting a similarity threshold. The system writes the compressed live data of the two or more data segments into the storage memory.
