Information processing apparatus, computer-readable recording medium having stored program for controlling information processing apparatus, and method for controlling information processing apparatus

摘要

A control device controls the switch device and the plurality of processing apparatuses such that, when one of replicated data pieces stored in two or more different storage devices among the plurality of storage devices is lost, the replicated data piece stored in a second storage device other than a first storage device storing lost replicated data piece among the two or more different storage devices is copied through the switch device to reconstruct the lost replicated data piece. Thus, a redundancy of replicated data is restored without affecting a bandwidth of a network.

主权项

1. An information processing apparatus, comprising:
a plurality of storage devices; a plurality of processing apparatuses; a switch device that switches a connection status between the plurality of storage devices and the plurality of processing apparatuses; and a control device that controls the switch device and the plurality of processing apparatuses such that, when one of replicated data pieces stored in a first storage device connected to a first processing apparatus among one or more storage devices connected to each of two or more different processing apparatuses among the plurality of processing apparatuses is lost, a third storage device, which is not connected to any of processing apparatuses, is connected to a second processing apparatus connected to a second storage device storing the one of replicated data pieces, and the one of replicated data pieces stored in the second storage device is copied to the third storage device, and the third storage device to which the one of replicated data pieces is copied is connected to the first processing apparatus instead of the first storage device.
