摘要： A method is provided. The method includes receiving a set of data blocks to be stored in a storage system. The storage system includes a plurality of non-volatile memory modules. The method also includes generating a set of segments based on the set of data blocks. A respective segment comprising portions of one or more erase blocks. The method further includes writing the set of segments to the non-volatile memory modules based on orderings of the portions of the one or more erase blocks.

摘要： A method for migration of data is provided. The method includes triggering a rebuild of data according to a first migration mechanism from a first storage drive to a second storage drive. Monitoring space utilization associated with the second storage drive, and adaptively switching the migration of the data from the first migration mechanism to a second migration mechanism based on the monitoring.

摘要： Apparatus and methods of operating solid-state drives in a storage system are described. A method includes adjusting, by a host controller of a storage system during run-time, storage bandwidth for a storage system process responsive to an input output (I/O) write request to write data to the storage system that includes multiple solid-state storage drives by determining an allocation share for the storage system process requesting to write the data, and responsive to determining an open segment usage by the storage system process is under the allocation share for the storage system process, opening a new segment for the storage system process.
