Abstract:
1. A storage control system, comprising: a plurality of storage devices for storing data; a controller that controls the writing of data to the plurality of storage devices and the reading of data from the plurality of storage devices; and a connection system that connects the controller to the plurality of storage devices, wherein the connection system comprises a plurality of device connectors connected to the plurality of storage devices; a plurality of bypasses corresponding to the plurality of device connectors, respectively; and a plurality of path switching units, each of which includes at least two of said plurality of bypasses, the plurality of path switching units being connected to corresponding ones of the plurality of device connectors, respectively, and to perform selective switching so as to connect either a corresponding device connector or a corresponding bypass of the corresponding device connector to the controller; the plurality of path switching units are serially connected between an upstream side where the controller is present and a downstream side where the plurality of storage devices is present; each of the plurality of path switching units connects the corresponding device connector to the controller when the corresponding device connector is normal, and switches connection of the controller from the corresponding device connector to the corresponding bypass thereof when an anomaly occurs in the corresponding device connector; and the controller accesses, via the bypass of the device connector exhibiting the anomaly, another device connector that exists further downstream than the device connector exhibiting the anomaly.
