摘要： A storage device is disclosed. The storage device may comprise storage for input encoded data. A controller may process read requests and write requests from a host computer on the data in the storage. An in-storage compute controller may receive a predicate from the host computer to be applied to the input encoded data. A transcoder may include an index mapper to map an input dictionary to an output dictionary, with one entry in the input dictionary mapped to an entry in the output dictionary, and another entry in the input dictionary mapped to a “don't care” entry in the output dictionary.

摘要： A system is disclosed. The system may include a processor that may issue a byte level protocol request including a byte address. The system may also include a first storage device and a second storage device. The first storage device and the second storage device may support a cache coherent interconnect protocol, the cache coherent interconnect protocol including a block level protocol and a byte level protocol. The first storage device and the second storage device are included in a redundant array of independent disks (RAID). The first storage device may include a first address range, and the second storage device may include a second address range. The second storage device may provide a RAID address range associated with the first address range and the second address range. A decoder associated with the second storage device may be configured to receive the request from the processor. The decoder may determine that the byte address in the RAID address range is associated with a target address range.

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.
