ABSTRACT:
A storage subsystem that directly interfaces with a network, provides connections for routers with a conventional multi-path function, and performs access load balancing among a plurality of input/output ports. Each channel controller is assigned with a channel controller network address, and a storage device is assigned with a storage device address (different from the network addresses of the channel controllers). Upon receiving a packet addressed to the storage device address from an external network device, a pseudo storage load routing function responds by notifying the external network device that the packet has been transmitted to the storage device with the storage device address, while performing input/output processing indicated by the packet for the storage device with the storage device address.
