Abstract: A receiving controller which receives a read request out of first and second storage controllers transfers the read request to an associated controller which is associated with a read source storage area out of the first and second storage controllers when the receiving controller is not the associated controller. It is however the receiving controller that reads the read-target data from a read source storage device, writes the read-target data to a cache memory of the receiving controller, and transmits the read-target data written in the cache memory of the receiving controller to a host apparatus.

Abstract: A data de-duplication in a distributed storage of data objects in a cluster system, in which plural data objects are distributed across a group of node apparatuses and stored in units of data blocks. Each metadata structure including a root metadata node and one or more direct metadata nodes, and optionally including one or more indirect metadata nodes; and a metadata object is stored for managing de-duplicated data blocks based on a metadata structure of the metadata object wherein at least one direct metadata node of the metadata structure of the metadata object includes a block reference pointing to a de-duplicated data block being associated with two or more data objects. Preferably, each of the metadata structures of the two or more data objects being associated with the de-duplicated data block includes a respective direct metadata node including an object reference to the metadata structure of the metadata object.
