Abstract: A storage device including: a nonvolatile memory device including a plurality of nonvolatile memory cells, a partial storage area and an overprovision storage area; and a controller configured to control the nonvolatile memory device, wherein when the controller detects a fault of the nonvolatile memory device, the controller negates the partial storage area, reassigns the overprovision storage area, which corresponds to a size of a user area, among the partial storage area, determines a device fail if the overprovision storage area is less than an overprovision threshold after the reassigning of the partial storage area, and determines a recovery success if the overprovision storage area is equal to or greater than the overprovision threshold after the reassigning of the partial storage area.

Abstract: A storage device includes memory devices and a controller. The controller translates a logical address received from a host to a physical address for the memory devices. The controller manages first correspondence information associated with correspondence relationships between logical addresses and physical addresses. The controller manages translation information that includes information of a minimal perfect hash (MPH) function. The MPH function is generated by using logical addresses indicating a memory region of a reference size as key values, when a size of a memory region indicated by logical addresses managed in the first correspondence information reaches the reference size. The controller manages second correspondence information associated with correspondence relationships between the logical addresses used as the key values and the MPH function of the translation information.

Abstract: A data storage system configured to perform a data rebuild operation via a reduced number of read requests includes a host and a redundant array of independent disks (RAID) device including a plurality of data storage devices. When the host receives data of a first region and data of a second region of a read-requested region of each of the data storage devices in response to a rebuild request, the host receives failed address list information of the second region. The first region is a normal region, and the second region is a faulty region. The host rebuilds the data of the second region based on the failed address list information.

Abstract: An operating method of a storage device that includes a nonvolatile memory device and a controller configured to control the nonvolatile memory device, the method including: detecting, by the controller, a fault of the nonvolatile memory device or the controller, notifying, by the controller, a host device of the fault, notifying, by the controller, the host device of one or more recovery schemes for recovering the fault, and recovering, by the controller, the fault in response to a recovery scheme selected by the host device.

Abstract: A load balancing method for a storage system includes receiving a log-in request from a client via a data network and a network adapter, using a control thread executed by one of a plurality of cores to assign a first connection between the client and a first data thread, and receiving I/O requests from the client and controlling the execution of one or more operations by a first core in response to the I/O requests.
