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. The processor may be further configured to place an input/output (I/O) request sent from the application to at least one storage device in the first SQ based at least in part on the I/O request being associated with the first NS, the first NS being associated with the first NVM Set, and the first NVM Set being associated with the first SQ.
