摘要： 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.

摘要： Fabric modules in a storage system offer differing device IDs from a deterministic sequence to a storage device being added to the storage system. The storage device that is being added accepts a device ID that is higher in the deterministic sequence. The fabric module that offered the device ID same as was accepted by the storage device determines to proceed with initializing the storage device.

摘要： A first amount of energy to be stored at one or more power loss protection (PLP) components is determined to enable storage of data at a plurality of storage devices of a storage system upon an occurrence of a power failure. A first voltage is provided to the one or more PLP components that corresponds to the first amount of energy. A second amount of energy to be stored at the one or more PLP components is determined based on a change in the storage system. A second voltage is provided to the one or more PLP components that corresponds to the second amount of energy.

摘要： Failure information associated with a plurality of blocks of a solid-state storage device of a plurality of solid-state storage devices is received. One or more blocks of the plurality of blocks storing uncorrectable data are identified based on the received failure information. A partial deallocation of the one or more blocks of the plurality of blocks is issued, the partial deallocation indicating that the one or more blocks store uncorrectable data. A remedial action associated with the one or more blocks of the plurality of blocks is performed.

摘要： Reads of data stored at the solid-state storage device are monitored. A set of data stored at the solid-state storage device is marked based on the monitoring of the reads of the data. A read request is received for a subset of data of the set of data stored at the storage device. In response to receiving the read request for the subset of data, the subset of data is relocated to a cache memory of the solid-state storage device.

摘要： A method includes receiving, by a storage drive and from a storage controller, a modified first submission queue command including a first logical unit identifier. The first submission queue command includes a first host identifier to identify a first host controller was previously received by the storage controller from the first host controller. The first submission queue command was modified by the storage controller to replace the first host identifier with the first logical unit identifier. The method also includes responsive to receiving the modified first submission queue command, identifying, by the storage drive, a first logical unit of storage based on the first logical unit identifier of the modified submission queue command. The method includes granting, by the storage drive, a reservation for access to the storage drive on behalf of the first host controller by associating the reservation for the first logical unit with a second logical unit of storage.

摘要： A request to perform an operation at a storage device of a storage array may be received. Schedulable units of the storage device may be identified. An availability of each schedulable unit of the schedulable units of the storage device may be determined. The requested operation may be scheduled based on the availability of each of the schedulable units of the storage device. Furthermore, the requested operation may be performed at the storage device based on the scheduling.

摘要： A priority queue including an order of local data relocation operations to be performed by a plurality of solid-state storage devices is maintained. An indication of a new local data relocation operation is received from a solid-state storage device of the plurality of solid-state storage devices for data stored at the solid-state storage device, the indication including information associated with the data. The new local data relocation operation is inserted into a position in the order of the priority queue based on the information associated with the data.
