Abstract: A data processing system is implemented with a backup PCI Express system, which is able to take over as the primary PCI Express system for ensuring that an endpoint device continues to function in a desired manner when a root complex in the primary PCI Express system is no longer functioning correctly or is deactivated for maintenance. The endpoint device is coupled to the primary root complex and a backup root complex through a multiplexer. When a failure or shutdown of the primary root complex is detected, the multiplexer is signaled to switch the communication of data from occurring between the primary root complex and the endpoint device to then occur between the backup root complex and the endpoint device. A PCI Express Link may be utilized to communicate such a failure or shutdown and/or to transfer information from the primary PCI Express system to the backup PCI Express system when the switch occurs.

Abstract: A storage control system receives an I/O request from a client for accessing storage resources that are logically divided into device groups, and determines a resource token request value associated with the I/O request and a target device group to which the I/O request is directed. The storage control system determines a number of allowed resource tokens to allocate to the client as a function of (i) the resource token request value, (ii) a sum total of resource tokens requested by other clients for accessing the target device group, and (iii) a total amount of resource tokens currently allocated to the target device group to which the I/O request is directed. The storage control system sends the determined number of allowed resource tokens to the client to thereby enable the client to limit a number of inflight I/O requests that the client issues to the storage control system.

Abstract: A data processing apparatus includes a power-source controller, a data processing device, a physical-layer section, a communication controller, and a state controller. The power-source controller controls a first power-source setting and a second power-source setting.
