Disclosed is a storage device which includes a nonvolatile memory device, and a controller configured to partition a storage space of the nonvolatile memory device into zones and access the storage space. Each zone corresponds to consecutive physical addresses of the nonvolatile memory device, and the controller is configured to map the consecutive physical addresses of each zone onto consecutive logical addresses. In response to a copy command being received from an external host device, the controller is configured to start a copy operation for copying data of a first zone of the zones to a second zone of the zones and send first read commands and first write commands to the nonvolatile memory device. In response to a suspend command, the controller is configured to suspend the copy operation, store progress status information about the copy operation, and send a suspend response to the external host device.

Stator for rotating electric machine with overlapping hairpin coils

The present disclosure relates to a stator for a rotating electric machine. A plurality of electrically-connected parts is formed on one side surface of a stator core to electrically connect a plurality of hairpins. Among portions of two electrically-connected parts adjacent to each other in a circumferential direction of the stator core, portions located at the same distance from the one side surface of the stator core have shortest distances therebetween, which are set to have difference values included in a preset range value. This may result in preventing a generation of a vulnerable portion at which two adjacent electrically-connected parts are excessively adjacent to each other in the circumferential direction of the stator core.

A storage system communicates with a host system and includes a storage device including storage medium divided into a plurality of blocks including high reliability blocks and reserve blocks, and a controller. The controller provides the host system with block information identifying the high reliability blocks among the plurality of blocks, receives a block allocation request from the host system, wherein the block allocation request is defined with reference to the block information and identifies at least one high reliability block to be used to store metadata, and allocates at least one high reliability block to a meta region in response to the block allocation request. The controller includes a bad block manager that manages an allocation operation performed in response to the block allocation request, and a repair module that repairs an error in metadata stored in one of the high reliability blocks.

Storage system managing metadata, host system controlling storage system, and storage system operating method

A computer system includes a host and a storage device. The host provides an input/output request (IO request). The storage device receives the IO request from the host and sends an interrupt informing input/output completion (IO completion) to the host after completing the IO request. The host adjusts the number of generated interrupts of the storage device using the number of delayed IOs. The computer system may adaptively control interrupt generation of the storage device based on a load status of a CPU or the number of delayed IOs. The interrupt generation of the storage device may be adjusted to obtain a CPU gain without loss of performance or processing time of the computer system.
