A storage device includes a memory device including a plurality of sequential areas and a random area other than the plurality of sequential areas, the plurality of sequential areas storing pieces of data corresponding to consecutive logical addresses input from a host, a buffer memory device configured to temporarily store write data corresponding to a write request provided from the host and an operation controller configured to generate combined data by adding dummy data to the write data having a size less than a program unit size of the memory device, a size of the dummy data corresponding to a difference between the size of the write data and the program unit size, store the combined data in the memory device, and store combined data information, relating to the combined data stored in the memory device, in the buffer memory device.

Storage device and method of operating the same

A storage system includes a plurality of storage devices coupled to at least one host through a network and configured to form a virtual network of virtual machines generated when the plurality of storage devices are coupled to the network, wherein each of the plurality of storage devices allocates memory resources to the virtual machines and shares device information for the plurality of storage devices through the virtual machines and wherein the host: selects from the plurality of storage devices a main storage device, and transmits a storage pool generation condition to the main storage device that identifies a number of storage pools and a capacity of each storage pool, wherein the main storage device generates at least one storage pool that satisfies the storage pool generation condition using the memory resources allocated to each of the virtual machines.

Storage system configuring a storage pool according to shared information, storage device therefor, and operating method thereof

A storage device includes a memory device including a plurality of memory areas respectively corresponding to a plurality of address groups each of which includes consecutive logical addresses provided by a host, a buffer memory including a common buffer and a plurality of zone buffers, the plurality of zone buffers respectively corresponding to the plurality of memory areas, and a memory controller for controlling the buffer memory to temporarily store write data corresponding to a logical address provided from the host in one of a zone buffer corresponding to the logical address and the common buffer according to whether a first size of the write data exceeds an available storage capacity of the zone buffer, the available storage capacity representing a size of an empty storage space of the zone buffer in which no data is stored.

Storage device including a buffer memory having a common buffer for storing over-sized write data, and operating method thereof

A storage system includes at least one host and a plurality of storage devices coupled to the at least one host through a network. Each of the plurality of storage devices generates state information of the storage device by monitoring hardware and software states of the storage device, and wherein, among the plurality of storage devices, a source storage device selects at least one target storage device based on the state information of storage devices other than the source storage device, and transmits distribution target data of the source storage device to the at least one target storage device, the source storage device being a storage device which needs data distribution.
