Abstract:
1. A storage apparatus ( 100 ) storing data, comprising: a storage device ( a first interface device ( a second interface device ( a main processor controlling data transfer inside the storage apparatus ( a first switch mutually connecting the main processor, the first interface device ( a sub-processor ( the first interface device ( a second switch connecting to the first switch; a physical port connecting the first interface device ( a virtual port device having multiple virtual function units which provide virtual ports of the first interface device ( a non-transparent bridge including a mapping table for translating device identifiers of the virtual function units, and relaying communication between the first switch and the second switch after translating the device identifier using the mapping table; the sub-processor ( enables any one or more of the virtual function units the device identifiers of which are registered with the mapping table; and does not enable any one or more of the virtual function units the device identifiers of which are registered with the mapping table; and the main processor communicates with the virtual function unit enabled by the sub-processor (
