Device and method for generating a logical path between connection of control device connected to a host device and memory device provided in said control device

摘要

A control device (4A) has a plurality of memory devices (1A), a first connection (92B) to be connected to a host device, and a second connection (92A) to be connected to an external memory control device (4B). The plurality of memory devices includes a memory device associated with the external memory device (4A). Provided are a first specifying unit (800) for specifying a host access external memory device, which is to be accessed by the host device, among the plurality of external memory devices; a second specifying unit (800) for specifying a mapping memory device, which is associated with the specified host access external memory device, among the plurality of memory devices; and a logical path generation unit for generating a logical path between the specified mapping memory device and the first connection.
