Abstract: A storage device configured to be connected to a redundant array of inexpensive disk (RAID) controller includes a plurality of non-volatile memories. A memory controller is configured to control the plurality of non-volatile memories to store data distributed by the RAID controller based on a RAID configuration signal received from the RAID controller. The memory controller is configured to perform self-diagnosis on the plurality of non-volatile memories to determine whether at least one of the plurality of non-volatile memories has an uncorrectable error when a RAID configuration signal is deactivated.

Abstract: Disclosed is a storage device which communicates with a first external storage device and includes a deduplication manager. A method of operating the storage device includes broadcasting, by the deduplication manager, a first fingerprint of first data, receiving a first response corresponding to the first fingerprint from the first external storage device, determining, by the deduplication manager, whether a reference flag of the first response has a first value or a second value, updating, by the deduplication manager, first mapping information of a mapping table based on the first response, based on a determination that the reference flag of the first response has the first value, and performing, by the deduplication manager, deduplication of the first data, based on the first response, based on a determination that the reference flag of the first response has the first value.

Abstract: A virtualized system includes a nonvolatile memory device, a processing circuitry configured to provide a virtualization environment, implement a plurality of virtual units and implement a virtual unit manager. The virtual units operate independently of each other in the virtualization environment and perform a flash translation layer operation inside the virtual units. The flash translation layer operation includes converting a logical block address associated with a storage access operation of the nonvolatile memory device to a physical block address of the nonvolatile memory device. The virtual unit manager controls the virtual units in the virtualization environment.

Abstract: A storage device includes a nonvolatile memory device (NVM) and a storage controller. The NVM includes a first region configured to store user data and a second region not allocated to a user. The storage controller is configured to be connected with a host device through both a first-type bus and a second-type bus different from the first-type bus. The storage controller is configured to receive a first and second request from the host device through the first-type bus. In response to the first request, the storage controller is configured to perform an operation on the NVM. In response to the second request, the storage controller is configured to store first data associated with the storage device in the second region and access the second-type bus to obtain second data of at least one external device obtained by the host device and store the second data in the second region.
