摘要： A method may include receiving, at a storage device, a command for a data transfer between the storage device and a host, determining a specified data rate for the data transfer, and performing the data transfer between the storage device and the host based on the command, wherein the storage device may control the data transfer based on the specified data rate. The data transfer may include a peak portion and an idle portion. The method may further include controlling, at the storage device, a peak portion and an idle portion of the data transfer based on the specified data rate. The method may further include controlling, at the storage device, the data transfer based on a peak burst size. The specified data rate may be received from the host and/or determined by the storage device by monitoring one or more parameters of a data transfer.

摘要： 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.

摘要： A storage device, and a method for operating a storage device. In some embodiments, the storage device includes storage media, and the method includes: determining, by the storage device, that the storage device is in a first fault state from which recovery is possible by power cycling the storage device or by formatting the storage media; determining, by the storage device, that the storage device is in a second fault state from which partial recovery is possible by operating the storage device with reduced performance, with reduced capacity, or in a read-only mode; and operating the storage device with reduced performance, with reduced capacity, or in the read-only mode.

摘要： A storage device includes non-volatile memory, a storage controller including a first controller processor connected to the non-volatile memory, and a second controller processor connected to the non-volatile memory, and shared memory to store a mapping table. The shared memory may be connected to the first controller processor and the second controller processor to share mapping table information between the first controller processor and the second controller processor. The storage controller may set a power mode of the first controller processor and the second controller processor based on an input/output intensity.

摘要： A method may include operating a first storage device and a second storage device as a redundant array, operating the first storage device in a fault resilient mode with at least partial read capability based on a fault condition of the first storage device, and rebuilding information from the first storage device on a spare storage device based on the fault condition of the first storage device. Rebuilding information from the first storage device on the spare storage device may include copying information from the first storage device to the spare storage device. The information from the first storage device may include data and/or parity information. The method may further include reading first information for a read or write operation from the first storage device based on a rebuild point of the spare storage device.

摘要： 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.
