Control method and information processing system

摘要

A control method for an information processing system including a first computer, a second computer, and a plurality of storage devices coupled to the first computer and the second computer through a switch, a processing performance of the second computer being higher than a processing performance of the first computer, the control method includes setting, by the switch, the first computer as a target for connection of the plurality of storage devices; transmitting, by the first computer, data to be processed from the first computer to the plurality of storage devices and thereby storing the data in the plurality of storage devices; switching, by the switch, the target from the first computer to the second computer when the storing is completed; and executing, by the second computer, processing of the data stored in the plurality of storage devices.

1. A control method for an information processing system including a first computer, a second computer, a control device, and a plurality of storage devices coupled to the first computer and the second computer through a switch, the control device being coupled to the first computer, the second computer and the switch, a processing performance of the second computer being higher than a processing performance of the first computer, the control method comprising:
setting, by the switch, the first computer as a target for connection of the plurality of storage device; outputting, by the control device, an instruction to transmit data from the first computer to the plurality of storage devices, to the first computer; transmitting, by the first computer, the data from the first computer to the plurality of storage devices and thereby storing the data in the plurality of storage devices; determining, by the control device, a completion time indicating time of completion of the storing the data in the plurality of storage devices, based on the data; powering on the second computer by the control device at a time that is prior to the determined completion time; outputting, by the control device, an instruction to cancel connection between the first computer and the plurality of storage devices and an instruction to make connection between the second computer and the plurality of storage devices, to the switch, when the storing is completed; switching, by the switch, the target from the first computer to the second computer when the storing is completed; outputting, by the control device, an instruction to process the data to the second computer after the connection is made; and executing, by the second computer, processing of the data stored in the plurality of storage devices.
