Claim:
1. A storage system comprising: a plurality of memory nodes configured to be connected to each other in two or more different directions, including a first memory node and a second memory node grouped as a logical memory node; and a connection unit configured to issue a first command including a first address and a second address in response to a request from outside, the first address designating the logical memory node, the second address designating the first memory node within the logical memory node, and the first memory node storing first data to be accessed by the first command, the second memory node storing second data which is redundant data of the first data, wherein the first memory node, in response to the first command, accesses the first data in the first memory node, and issues a second command for accessing the second data, the second command including the first address designating the logical memory node including the grouped first and second memory nodes and a third address designating the second memory node within the logical memory node, so as to autonomously identify the second memory node storing the redundant data of the first data.
