摘要： An object is to provide an information processing apparatus capable of improving the availability as a system while improving the reliability of a data transfer path and a data transfer method. An information processing apparatus has a data transfer path branching in a tree structure, from a root node to a plurality of nodes while communicably coupling therebetween and transmitting serial data between the root node and the plurality of nodes, including two internode data transfer paths provided between at least a pair of nodes of the plurality of nodes, through which serial data transfer is performed; and a routing processing unit provided to each terminal nodes that are the nodes on both ends of the internode data transfer path, transfers the return data from the transmission destination node to the transmission source node by using the same internode data transfer path as the internode data transfer path used for data transfer to the transmission destination node, when each of the terminal nodes transfers data received from any of another nodes being a transmission source to any of the nodes being a transmission destination via the other terminal node.

摘要： A storage system comprises a storage device for storing data, a control apparatus which controls the storage device and comprises multiple communication ports, and a switch apparatus which expands the number of storage device couplings and comprises multiple communication ports. Respective multiple communication ports of the control apparatus are coupled to respective multiple communication ports of the switch apparatus, and the switch apparatus is coupled to the storage device. The control apparatus configures at least one communication port of the multiple communication ports of the control apparatus, to a dedicated communication port for outputting only a prescribed command issued when a failure is detected.

摘要： Reduction of data processing capacity attributable to the occurrence of a failure is prevented by promptly identifying the failure location. A storage apparatus includes a plurality of expanders connected to storage media storing data sent from a host system, and a controller for controlling the expanders, wherein the controller sends a failure detection command to the plurality of expanders; the plurality of expanders store the command in their own storage units; and if one expander from among the plurality of expanders detects a failure in another expander immediately following and connected to the one expander, the one expander reads the command stored in a storage unit for the one expander and sends a response including failure detection information corresponding to the command to the controller.
摘要翻译：通过及时识别故障位置，可以防止归因于故障发生的数据处理能力的降低。存储装置包括连接到存储从主机系统发送的数据的存储介质的多个扩展器和用于控制扩展器的控制器，其中控制器向多个扩展器发送故障检测命令; 多个扩展器将命令存储在它们自己的存储单元中; 并且如果多个扩展器中的一个扩展器检测到紧跟在一个扩展器之后的另一扩展器中的故障，则一个扩展器读取存储在一个扩展器的存储单元中的命令，并发送包括对应于命令给控制器。
