Abstract: An indication is received from a storage device that an attempt to read a portion of data from a block of the storage device has failed. A command is transmitted to the storage device to perform a scan on data stored at the block comprising the portion of data to acquire failure information associated with a plurality of subsets of the data stored at the block. The failure information associated with the plurality of subsets of the data stored at the block is received from the storage device.

Abstract: A storage unit has one or more processing devices, a solid-state drive and an open blocks cache memory. The open blocks cache memory holds open blocks of data or metadata and holds closed blocks of data or metadata pending writing to the solid-state drive. Closed blocks of data or metadata are written to the solid-state drive and open blocks of data or metadata are written to the open blocks cache memory. Values for open blocks in the open blocks cache memory are tracked. The values are adjusted in a first direction when an open block is written to the open blocks cache memory, and the values are adjusted in a second direction when an open block in the open blocks cache memory is closed and written from the open blocks cache memory to the solid-state drive.

Abstract: A command to relocate data is transmitted by a storage controller. The command includes first address information associated with a first set of blocks storing the data at one or more storage devices using a first programming mode and second address information associated with a second set of blocks at the one or more storage devices to store the relocated data using a second programming mode. The command causes the relocation of the data from the first set of blocks to the second set of blocks while bypassing sending the data to the storage controller. An acknowledgement is received that the relocated data has been stored at the second number of blocks.

Abstract: One or more performance parameters associated with data stored at a storage device of a plurality of storage devices are received by a storage controller. A first number of blocks of the storage device to a high resiliency portion and a second number of blocks of the storage device to a low resiliency portion of the storage device are allocated based on the one or more performance parameters.

Abstract: A command is transmitted to a storage device to relocate first data that partially fills a first erase block of the storage device and second data that partially fills a second erase block of the storage device to a third erase block of the storage device, wherein the command causes the relocation of the first data and the second data while bypassing sending the data to the storage controller. An acknowledgement that the first data and the second data have been stored at the third erase block is received from the storage device.

Abstract: A storage system includes solid-state storage devices and a storage controller operatively coupled to the solid-state storage devices, the storage controller including a processing device, the processing device to receive, from a solid-state storage device of the solid-state storage devices, an indication of an occurrence of triggering event associated with data stored at a first data block of the solid-state storage device. In response to receiving the indication of the occurrence of the triggering event, a second data block of the solid-state storage device is identified for storage of the data. A command in transmitted to the solid-state storage device that includes address information associated with the second data block of the solid-state storage device for storage of the data, wherein the command causes the solid-state storage device to program the data to the second data block.

Abstract: Maintaining data associate with a storage device is described. A method may include receiving, by an application executed by a storage array controller of a host server of a solid-state storage array comprising a plurality of solid-state storage devices, an indication of a change in state of a solid-state storage device of the plurality of solid-state storage devices. In response to receiving the indication, the method may also include retrieving a plurality of tables stored at a volatile memory of the solid-state storage device, the plurality of tables comprising information associated with characteristics of a plurality of data blocks of the solid-state storage device. The method may also include identifying one or more rules associated with the plurality of tables and creating, by the storage array controller, a new plurality of tables based on the one or more rules.

Abstract: An indication of a power-up of a storage device may be received. In response to receiving the indication, a first data structure that is stored at a volatile memory of the storage device may be retrieved. The first data structure may include first information associated with characteristics of a plurality of data blocks of the storage device. A second data structure stored at a non-volatile memory of the storage device may be retrieved where the second data structure includes second information associated with the characteristics of the plurality of data blocks of the storage device. A new data structure may be created based on the first information and the second information and a rule where an entry of the new data structure is provided a value from one of the first information or the second information based on the rule.

Abstract: A method includes, responsive to receiving a modified first reservation command from a storage controller, identifying, by a storage drive, a first range of storage based on a first range identifier of the modified reservation command. The method also includes granting, by the storage drive, a reservation for access to the storage drive on behalf of a first host controller by associating the reservation for the first range with a second range of storage.
