  • Patent number: 11409439
    Abstract: A host interface layer in a storage device is described. The host interface layer may include an arbitrator to select a first submission queue (SQ) from a set including at least the first SQ and a second SQ. The first SQ may be associated with a first Quality of Service (QoS) level, and the second SQ may be associated with a second QoS level. A command fetcher may retrieve an input/output (I/O) request from the first SQ. A command parser may place the I/O request in a first command queue from a set including at least the first command queue and a second command queue. The arbitrator may be configured to select the first SQ based at least in part on a first weight associated with the first SQ and a second weight associated with the second SQ.

  • Publication number: 20220147392
    Abstract: A system is disclosed. The system may include a processor. The system may also include a first submission queue (SQ) and a second SQ. The first SQ may be associated with a first Quality of Service (QoS) level and the second SQ may be associated with a second QoS level, the first QoS level being different from the second QoS level. An application may be running on the processor and using a first namespace (NS). The processor may be configured to receive a first Non-Volatile Memory (NVM) Set create command to establish a first NVM Set associated with the first SQ. The processor may be further configured to receive a second NVM Set create command to establish a second NVM Set associated with the second SQ. The processor may be further configured to receive a first NS create command to establish a first NS associated with the first NVM Set. The processor may be further configured to receive a second NS create command to establish a second NS associated with the second NVM Set.
