Abstract: Recovering corrupted data through speculative bitflip and cross-validation, including altering a first data portion stored in a storage device, wherein the first data portion contains an error; calculating a hash value using the altered first data portion; comparing the hash value calculated using the altered first data portion to a stored hash value for the first data portion; and based on the comparing, determining whether the altering corrects the error in the first data portion.

Abstract: Continuous value data redundancy, including: receiving, by a storage system, a dataset; determining, based on a data resiliency metric, an integer redundancy value for the dataset from among a plurality of redundancy values; and generating, based on the integer redundancy value for the dataset, data recovery information for the dataset, wherein the integer redundancy value for the dataset is different from at least one other integer redundancy value for another dataset stored within the storage system.

Abstract: Accelerating segment metadata head scans for storage system controller failover, including: receiving, by a secondary storage unit corresponding to a primary storage unit, a request to store a data segment; storing the data segment and segment metadata at the head of the data segment; and storing, in a data structure, data indicating an erase block storing the segment metadata and indicating an offset in the erase block where the segment metadata is stored.

Abstract: An amount of power to be used by a storage system including storage devices having multiplane dies is identified. A number of planes of one or more of the multiplane dies used simultaneously for accessing data are adjusted such that a power usage of the storage system is less than or equal to the amount of power. A block size for allocating blocks by combining a set of erase blocks at a same address in separate planes based on the adjusted number of planes is utilized.

Abstract: Coordinating multiple storage controllers in a cloud-based storage system, including: reading, by a first storage controller and a second storage controller, first heartbeat data from a first region of memory of a storage device assigned to the first storage controller and second heartbeat data from a second region of memory of the storage device assigned to a second storage controller; and determining, for the first storage controller and the second storage controller, a corresponding state of the storage device based on the first heartbeat data and the second heartbeat data.

Abstract: A storage system has zones in solid-state storage memory, with power loss protection. The system identifies portions of data for processes that utilize power loss protection. The system determines to activate or deactivate power loss protection for the portions of data for the processes. The system tracks activation and deactivation of power loss protection in zones in the solid-state storage memory, in accordance with the portions of data having power loss protection activated or deactivated.
