Abstract: A solid-state drive that can service multiple users or tenants and workloads (that is, multiple tenants) by enabling assigned bandwidth share of the solid-state drive across tenants is provided. The assigned bandwidth share is enabled for command submissions within a same assigned domain in addition to a weighted bandwidth share and quality of service control across different domains from all tenants.

Abstract: A first type of command is suspended, by a controller of a non-volatile memory device, in response to determining that a second type of command is waiting for execution. The first type of command is split into a plurality of chunks based on a computed criteria. A second type of command is executed in between execution of at least two chunks of the first type of command.

Abstract: A data structure is maintained for performing a program operation that is allowed to be suspended to perform reads in a NAND device, where the data structure indicates a plurality of tiers, where each tier of the plurality of tiers has a number of allowed suspends of the program operation while executing in the tier, and where a sum of the number of allowed suspends for all tiers of the plurality of tiers equals a maximum allowed number of suspends of the program operation. In response to performing a resume of the program operation, after performing a read following a suspend of the program operation, a determination is made of a tier of the plurality of tiers for the program operation and a subsequent suspend of the program operation is performed only after a measure of progress of the program operation has been exceeded in the determined tier.
