Abstract: 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.

Abstract: A method of operating a plurality of blades of a storage system, performed by the storage system, is provided. The method includes writing data stripes across one or more sets of blades of the plurality of blades within resiliency groups, the plurality of blades having computing resources and storage memory, each resiliency group supporting data recovery in case of loss of a specified number of blades of the resiliency group. The method includes transferring data from a first resiliency group to a second resiliency group, responsive to a change in geometry of the storage system.
