Abstract
A server device is formed by a plurality of network interface processors connected to a network, each network interface processor having a network interface local memory functioning as a cache memory for storing a part of server data and a network interface local processor, at least one storage interface processor connected with a storage device for storing the server data, and a connection network for connecting the network interface processors and the storage interface processor. In this server device, the network interface local processor of one network interface processor carries out a control processing such that a requested data stored In the network interface local memory of the one network Interface processor is transmitted to the network when a request received from the network at the one network interface processor satisfies a prescribed first condition, and the request is given to the storage interface processor via the connection network when the request satisfies a prescribed second condition and the requested data is transmitted to the network upon receiving the requested data returned from the storage interface processor to the one network interface processor via the…
