Abstract: A storage device includes a plurality of memory dies, corresponding to a plurality of channels and a plurality of ways, and a storage controller connected to the plurality of memory dies. The storage controller may be configured to receive commands from a plurality of tenants; in response to a number of the received commands being equal to or greater than a predetermined threshold value, determine a first number of channels required to store first data of a first tenant in each way of the plurality of ways based on commands received from the first tenant; and store the first data in the first number of memory dies in each way of the plurality of ways. The first data may be stored in memory dies that correspond to the plurality of channels in at least a portion or an entire portion of the plurality of ways.

Abstract: In a method of operating a storage device, first information associated with operation of the storage device is received from a host device. Second information internally generated based on write requests, read requests, and operation of the storage device is received. Program commands and read commands are transmitted to nonvolatile memories. Suspension commands are transmitted to at least one of nonvolatile memories. The suspension commands are generated based on the first and second information and are used to temporarily stop program operations performed based on the program commands. The number and timing of transmitting the suspension commands are controlled based on the first and second information. In response to changing at least one of the write requests and the read requests, the number and timing of transmitting the suspension commands are adaptively changed.

Abstract: A storage device includes: a memory; and a storage controller configured to control the memory and to update meta data by controlling the memory. The storage controller includes a journal manager having a range table. The journal manager is configured to: generate a plurality of journal data associated with the update of the meta data, restore the meta data by sequentially performing a replay operation for each of the plurality of journal data, update the range table based on the plurality of journal data, and skip the replay operation for at least one of the plurality of journal data based on the range table.
