Abstract: A computer storage device having a host interface, a controller, non-volatile storage media, and firmware. The firmware instructs the controller to: limit a crypto key to be used in data access requests made in a first namespace allocated on the non-volatile storage media of the computer storage device; store data in the first namespace in an encrypted form that is to be decrypted using the crypto key; free a portion of the non-volatile storage media from the first namespace, the portion storing the data; and make the portion of the non-volatile storage media available in a second namespace without erasing the data stored in the portion of the non-volatile storage media.

Abstract: A computer storage device having a host interface, a controller, non-volatile storage media, and firmware. The firmware instructs the controller to: receive, via the host interface, a request from a host to allocate a namespace of a quantity of non-volatile memory; generate, in response to the request, a namespace map identifying a plurality of blocks of addresses having a same predetermined block size, and a partial block of addresses having a size smaller than the predetermined block size; and convert, using the namespace map, logical addresses in the namespace communicated from the host to physical addresses for the quantity of the non-volatile memory. For example, the request for allocating the namespace can be in accordance with an NVMe protocol.

Abstract: A computer having a plurality of accounts and a storage device having a host interface, a controller, non-volatile storage media, and firmware. Each account has a namespace identifier that identifies the allocation of a portion of the non-volatile storage media to the account. The storage device stores a namespace map that defines the mapping between the logical addresses in a namespace identified by the namespace identifier and the logical addresses, in a capacity of the storage device, that correspond to the portion of the non-volatile storage media allocated to and accessible to the account. The account accesses the portion of the non-volatile storage media via the logical addresses in the namespace. The firmware of the storage device configures the controller to convert, using the namespace map, the logical addresses in the namespace to the physical addresses of the portion of the non-volatile storage media.

Abstract: A memory system having a set of media, a plurality of inter-process communication channels, and a controller configured to run a plurality of processes that communicate with each other using inter-process communication messages transmitted via the plurality of inter-process communication channels, in response to requests from a host system to store data in the media or retrieve data from the media. The memory system has a message manager that examines requests from the host system, identifies a plurality of combinable requests, generates a combined request, and provides the combined request to the plurality of processes as a substitute of the plurality of combinable requests.

Abstract: A computer system having a host in communication with a data storage device is coupled to the host via a peripheral bus and a host interface. The data storage device has a controller, non-volatile storage media; and firmware containing instructions configures the operations of the controller. The host transmits a sequence of commands to the storage device to read data items from, or write data items to, the non-volatile storage media. The storage device examines a subset of the commands to determine whether or not data items identified in the subset are addressed sequentially and optimizes processing of at least a portion of the sequence of commands based on a result of a determination of whether or not data items identified in the subset are addressed sequentially.

Abstract: A memory system having a set of media, a set of resources, and a controller configured via firmware to use the set of resources in processing requests from a host system to store data in the media or retrieve data from the media. The memory system has a workload manager that analyzes activity records in an execution log for a time period where each of the activity records can indicate whether a processor of the controller is in an idle state during a time slot in the time period. The workload manager identifies idle time slots within the time period during which time slots one or more lightly-loaded processors in the plurality of processors are in the idle state, and adjusts a configuration of the controller to direct tasks from one or more heavily-loaded processors to the one or more lightly-loaded processors.

Abstract: A memory system having a mode indicator, a set of hardware resources, a set of media, and a controller. When the mode indicator identifies a factory mode, a first portion of the hardware resources is reserved for performance of factory functions by the controller and a second portion of the hardware resources is allocated for performance of normal functions. When the mode indicator identifies a user mode, both the first portion and the second portion are allocated for the performance of the normal function. The normal functions are performed by the controller to at least store data in and retrieve data from the set of media in response to requests from a host system.

Abstract: A computer system having a host coupled to a storage device via a peripheral component interconnect express bus. The host communicates write commands of low priority to the storage device, which places them in a queue for execution at an idle time. In response to a determination that the storage device is in an idle state, the storage device best accommodates the write commands in the idle queue in connection with housekeeping tasks, such as garbage collection and wear leveling, to best reduce write amplification.

Abstract: A computer having a plurality of accounts and a storage device having a host interface, a controller, non-volatile storage media, and firmware. An account is configured with at least a predetermined speed in accessing the non-volatile storage media by allocating a number of input/output submission queues in the buffer area of the host. The number can be determined from a ratio between the predetermined speed configured for the account and a saturated speed of the storage device with sufficient submission queues. Data access requests from the account are evenly distributed to the submission queues allocated for the exclusive use by the account; and the controller, configured via the firmware, processes with equal priority the submission queues configured for the storage device. Thus, the account can have at least the predetermined speed in accessing the non-volatile storage media, regardless of how other accounts access the storage device.

Abstract: A computer storage device having: a host interface; a controller; non-volatile storage media; and firmware. The firmware instructs the controller to: divide a contiguous logical address capacity into blocks according to a predetermined block size; and maintain a data structure to identify: free blocks are available for allocation to new namespaces; and blocks that have been allocated to namespaces in use. Based on the content of the data structure, non-contiguous blocks can be allocated to a namespace; and logical addresses in the namespace can be translated to physical addresses for addressing the non-volatile storage media of the storage device.
