Abstract:
Systems, methods and/or devices are used to enable triggering a process to reduce declared capacity of a storage device in a multi-storage-device storage system. In one aspect, the method includes: (1) obtaining, for each storage device of a plurality of storage devices of the storage system, one or more metrics of the storage device, the storage device including non-volatile memory, (2) detecting a trigger condition for reducing declared capacity of the non-volatile memory of a respective storage device of the plurality of storage devices, the trigger condition detected in accordance with the one or more metrics of one or more storage devices, and (3) enabling an amelioration process associated with the detected trigger condition, the amelioration process to reduce declared capacity of the non-volatile memory of the respective storage device. In some embodiments, the respective storage device includes one or more flash memory devices.
Abstract:
Apparatuses, systems, methods, and computer program products are disclosed for key-value stores with partial data access. An interface module is configured to receive a data object for storage in a key-value store. The data object may include a key and a value. A block object module is configured to generate a plurality of block objects smaller than the data object. A block object may include a new key and a new value. The new key may be based on the key for the data object and on metadata for the new value. The new value may be based on at least a portion of the value for the data object. A storage module is configured to store the block objects in the key-value store.

Systems, methods and/or devices are used to enable notification of a trigger condition to reduce declared capacity of a storage device in a multi-storage-device storage system. In one aspect, the method includes: (1) obtaining, for each storage device of a plurality of storage devices, one or more metrics of the storage device, the storage device including non-volatile memory, (2) detecting a trigger condition for reducing declared capacity of the non-volatile memory of a respective storage device of the plurality of storage devices, the trigger condition detected in accordance with the one or more metrics of two or more of the storage devices, and (3) notifying a host of the trigger condition for reducing declared capacity of the non-volatile memory of the respective storage device, the trigger condition for enabling performance of an amelioration process to reduce declared capacity of the non-volatile memory of the respective storage device.
Abstract:
Systems, methods and/or devices are used to reduce declared capacity of non-volatile memory of a storage device in a storage system. In one aspect, the method includes, detecting an amelioration trigger for reducing declared capacity of non-volatile memory of a storage device of the storage system, and in accordance with the detected amelioration trigger, performing an amelioration process to reduce declared capacity of the non-volatile memory of the storage device, the performing including making specific logical addresses of a logical address space unavailable to a host. In some embodiments, the storage device includes one or more flash memory devices. In some embodiments, the detecting, the performing, or both are performed by the storage device, or by one or more subsystems of the storage system distinct from the storage device, or by the host.
Abstract:
Systems, methods and/or devices are used to enable triggering, at a host system, a process to reduce declared capacity of a storage device. In one aspect, the method includes, at a host to which a storage device of the storage system is operatively coupled: (1) obtaining one or more metrics of the storage device, the storage device including non-volatile memory, (2) detecting a trigger condition in accordance with the one or more metrics of the storage device, and (3) enabling an amelioration process associated with the detected trigger condition, the amelioration process to reduce declared capacity of the non-volatile memory of the storage device. In some embodiments, the storage device includes one or more flash memory devices.
