Abstract: 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.

Abstract: 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.

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 storage device associated with a storage array may be identified. Information specifying an organization of data included in a data structure may be retrieved from the storage device. The data may be associated with characteristics of a plurality of data blocks of the storage device. A read operation or a write operation may be performed for the storage device based on the information specifying the organization of the data included in the data structure that is associated with the characteristics of the plurality of data blocks of the storage device.

Abstract: The disclosure is directed to a system and method for controlling a non-volatile memory (NVM) device with controller-opaque commands issued by a host. A device controller is configured to receive a command script from a host. The device controller executes one or more commands of the command script including sending one or more operations of the command script to a NVM device in communication with the device controller. The device controller is enabled to provide at least a portion of the one or more operations from the command script to be executed by the NVM device without any embedded knowledge by the device controller of the actions of and/or consequences of the operations, thereby allowing the host to access NVM commands that are not necessarily supported by the device controller.
