Abstract: A method and a memory device are provided. A controller of the memory device retrieves a first command from a host memory. The controller stores a first identifier of the first command in a set-aside buffer of the memory device. The controller retrieves a second command from the host memory. The controller initiates processing of the first command and the second command based on a second identifier of the second command corresponding to the first identifier.

Abstract: A method may include determining, with a queue availability module, that an entry is available in a queue, asserting a bit in a register based on determining that an entry is available in the queue, determining, with a processor, that the bit is asserted, and processing, with the processor, the entry in the queue based on determining that the bit is asserted. The method may further include storing the register in a tightly coupled memory associated with the processor. The method may further include storing the queue in the tightly coupled memory. The method may further include determining, with the queue availability module, that an entry is available in a second queue, and asserting a second bit in the register based on determining that an entry is available in the second queue. The method may further include finding the first bit in the register using a find first instruction.

Abstract: Systems and methods for processing copy commands are disclosed. A first controller of the storage device receives a copy command from a host via a first queue. The storage device generates, based on the copy command, a read command and a write command, and submits the read and write commands to a second controller of the storage device via a second queue. The second controller retrieves and processes the read and write commands from the second queue. The storage device reads, based on the processing of the read command, data stored in a first location of a storage media associated with a source address, and writes the data to a second location of the storage media associated with a destination address. The first controller transmits a signal to the host for indicating completion of the copy command.

Abstract: A method for tracking a progress of data copying for a live migration includes transferring, by a storage controller, a first data structure to a live migration server, the first data structure including a first status identifier indicating a location of a source data to be copied from a source storage to a target storage, and selectively generating or selectively clearing, by the storage controller, a second status identifier in or from a second data structure, based on a first current copying location of the live migration server, the second status identifier indicating a location of a first user data write to the source storage.

Abstract: Methods and systems for processing a command from a host to a storage device are disclosed. A first controller of the storage device receives a first command from the host via a first queue. The first queue is exposed to the host. The storage device generates a second command based on the first command, and submits the second command to a second controller of the storage device via a second queue. The second command and the second queue are unexposed to the host. The second controller obtains and processes the second command from the second queue, where the processing is for accessing non-volatile storage media of the storage device. Based on status of the second command, the first controller transmits a signal to the host for indicating completion of the first command.

Abstract: A method and a memory device are provided. A controller of the memory device retrieves a first command burst from a host memory. The first command burst includes a sequence of one or more commands from a first submission queue. The controller identifies that at least one command in the first command burst is at least one first fused command of a first set of fused commands. The first set of fused commands is to be processed atomically in the memory device, and a remainder of the first set of fused commands is on the first submission queue. The controller stores at least an identifier of the at least one first fused command in a set-aside buffer of the memory device.
