Storage system for data replication

摘要

A storage system includes a replication source storage device equipped with a replication source storage unit storing replication target data, and a replication destination storage unit which is provided to a replication destination storage device and is a replication destination of the replication target data, which are connected with each other over a network. The replication destination storage unit is equipped with a host bus adapter which is an interface for connecting the replication destination storage unit with the network. Each of the replication source storage device and the host bus adapter provided to the replication destination storage unit is equipped with a connection device which uses the network, located between them, as an extension of a bus of the replication source storage device, and connects the replication source storage device and the host bus adapter provided to the replication destination storage unit with each other.

1. A storage system comprising:
a replication source storage device comprising a replication source storage unit which is configured to store replication target data, and a replication destination storage unit which is configured to be governed by a replication destination storage device and is a replication destination of the replication target data, the replication source storage device and the replication destination storage unit being connected with each other over an Ethernet network, wherein the replication destination storage unit comprising a host bus adapter which is configured to provide an interface for connecting the replication destination storage unit with the network, the host bust adapter being configured to be governed by the replication destination storage unit, and each of the replication source storage device and the host bus adapter are equipped with an ExpEther connection device, the ExpEther connection device using the Ethernet network, located between the replication source storage device and the host bus adapter, as an extension of a bus of the replication source storage device, and directly connecting the replication source storage device and the host bus adapter with each other, wherein the replication source storage device includes a connection control unit configured to establish a connection between ExpEther devices, and to perform control to connect the replication destination storage unit with the extension of the bus of the replication source storage device via the host bus adapter.
