Abstract:
Disclosed is a method of operating a storage device which communicates with a host device. The method includes receiving a first request indicating a setting operation of a first virtual function corresponding to a first virtual machine from the host device executing the first virtual machine, the first request including first requirement level information of the first virtual machine, setting a first performance attribution of the first virtual function, based on the first requirement level information, and providing the host device with a done response indicating that the first performance attribution is set.
Abstract:
A storage device includes a nonvolatile memory and a controller configured to manage data, stored in the nonvolatile memory, through a plurality of namespaces. The plurality of namespaces may include a first namespace, allocated to a first logical address space, and a second namespace allocated to a second logical address space, contiguous to the first logical address space. The controller may be configured to delete the first namespace in the first logical address space in response to a request of deleting the first name space, to copy the mapping information on the second namespace from the second logical address space to the first logical address space, and to load the mapping information on the second namespace into a cache.
Abstract:
A storage device includes a nonvolatile memory device including a plurality of zones, each of the plurality of zones including a plurality of logical addresses, and a storage controller configured to control the nonvolatile memory, the storage controller including at least one buffer directly accessible by a host device, the buffer including at least one random write area and a write pointer, the write pointer configured to store a position indicating a starting logical address of the random write area, and the buffer configured to write data into the random write area based on the position of the write pointer in response to the buffer receiving the write data from the host device.
Abstract:
In one embodiment, the method includes buffering, under control of a memory controller, received data and an associated program entity in a buffer. The program entity includes first address information and second address information, the first address information indicates an address of the buffer storing the received data, and the second address information indicates an address in the memory to store the received data. The method further includes storing, at the memory controller, management information. The management information includes program information, and the program information includes a pointer to the program entity in the buffer. The method also includes transferring the received data from the buffer to the memory based on the management information and the program entity.
