Abstract:
PROBLEM TO BE SOLVED: To flexibly replace accelerators used by a host.SOLUTION: An accelerator management device has an accelerator string DB which stores an accelerator identifier in association with an application identifier. The accelerator management device has an accelerator loading information DB for storing an accelerator identifier of an accelerator mounted to a slog in association with each slot identifier for identifying each slot of an expansion I/O box. The accelerator management device identifies an accelerator identifier corresponding to application from the accelerator string DB when it receives an execution request of the application from a host. The accelerator management device identifies a slot identifier corresponding to the identified accelerator identifier from the accelerator loading information DB. The accelerator management device allots a slot to be identified by the identified slot identifier to the host.

PROBLEM TO BE SOLVED: To prevent a processing resource from being uselessly used, with low cost.SOLUTION: In an information processing apparatus 100 switching connection between a recording media reading device 131 and either one of a first control unit 110 and a second control unit 120 at a connection switching unit 132, when a connection switching unit 132 connects between the first control unit 110 and the recording media reading device 131, the second control unit 120 blocks a communication with a bus conversion unit 133 which converts a first rating signal acquired from a first bus 141 into a second rating signal to provide it to a second bus 142 and converts a second rating signal acquired from the second bus 142 into a first rating signal to provide it to the first bus 141.
Abstract:
PROBLEM TO BE SOLVED: To suppress the power supply stop of a host computer in exchanging a switch for connecting a host computer and an input/output device.SOLUTION: A switching control device monitors access executed from a server to the PCIe switch of an operation system extension I/O box to which an input/output device is connected. The switching control device extracts setting information set in an operation system PCIe switch by the server for showing the connection information of the server and the input/output device from the access to be monitored, and makes a storage part store the setting information. The switching control device sets the setting information stored in the storage part in the PCIe switch of a standby system extension I/O box to which the input/output device is connected. The switching control device switches the access destination of the server from the operation system PCIe switch to the standby system PCIe switch when the operation system PCIe switch breaks down.
