Abstract
Technology is disclosed herein for aborting a tail portion of a command queue in a storage device. In one aspect, one or more control circuits of a storage system are configured to abort tasks at a tail end of a command queue in response to receiving a task tail abort command. However, tasks at the head end of the command queue may still be executed. Thus, the head end of the command queue need not be rebuilt after the task tail abort command is performed. Therefore, considerable time is saved by not having to rebuild the head end of the command queue. Note that the task tail abort command may be received while the storage system is in a sequential command execution mode, in which tasks are executed in the order of their respective task identifiers.
