ABSTRACT:
A storage apparatus comprising a plurality of nodes through which write-data received from a host is written into a disc, each of the nodes including a first memory in which the write-data is temporarily stored, a second memory, a copier which copies both write-data stored in the first memory and write-data stored in a first memory of another node into the second memory, the copier being able to make communication with a copier of the another node through a copier-interface, and a mode-switch which, when a trouble is found in the copier-interface, writes the write-data stored in the first memory into the disc without copying the write-data into the second memory.
