Abstract: A system and method for satisfying Quality of Service (QoS) attributes for a stream using a storage device with multi-stream capability is described. The storage device may include memory to store data. A host interface may receive requests, some of which may be associated with a stream. A host interface layer may schedule the requests in a manner that may satisfy the QoS attribute for the stream.

Abstract: A method for communicating with a device may include running, at a device, an operating system, communicating, using a first function of an interconnect, with the device, and communicating, using a second function of the interconnect, with the operating system. The operating system may include communication logic, and the communicating with the operating may include communicating with the communication logic. The communication logic may one or more terminal support drivers, and the communicating with the communication logic may include communicating with the one or more terminal support drivers using a terminal application. The terminal application may run on a host. The second function of the interconnect may be configured to operate with a controller. The communicating with the operating system may include communicating with the operating system based on a privilege information. The host may be a management controller. The method may further include controlling, using the second function of the interconnect, a program on the operating system.

Abstract: A storage device is disclosed. The storage device may include a storage for a data and a controller to process an input/output (I/O) request from a host processor on the data in the storage. A computational storage unit may implement at least one service for execution on the data in the storage. A command router may route a command received from the host processor to the controller or the computational storage unit based at least in part on the command.

Abstract: A method of operating a storage device may include determining a fault condition of the storage device, selecting a fault resilient mode based on the fault condition of the storage device, and operating the storage device in the selected fault resilient mode. The selected fault resilient mode may include one of a power cycle mode, a reformat mode, a reduced capacity read-only mode, a reduced capacity mode, a reduced performance mode, a read-only mode, a partial read-only mode, a temporary read-only mode, a temporary partial read-only mode, or a vulnerable mode. The storage device may be configured to perform a namespace capacity management command received from the host. The namespace capacity management command may include a resize subcommand and/or a zero-size namespace subcommand. The storage device may report the selected fault resilient mode to a host.

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. 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.

Abstract: A storage system, and a method for operating a storage system. In some embodiments, the system includes a first storage device and a second storage device, and the method includes: determining that the first storage device is in a read-only state and that the second storage device is in a read-write state; performing a write operation, of a first stripe, to the storage system; performing a first read operation, of a second stripe, from the storage system; and performing a second read operation, of the first stripe, from the storage system, wherein: the performing of the write operation includes: writing a portion of the first stripe to the second storage device, and making an entry in a mapping table for the first stripe.
