Abstract: The saving of data in an information technology (IT) infrastructure offering activity resumption functions is disclosed. For these purposes, a saving system is provided with at least one first and one second sets of data storage and at least one first and one second memory controllers associated with the first and second data storage, respectively. The saving system is furthermore provided with a microcontroller configured to duplicate a stream of commands and of data destined for the first memory controller to the second memory controller in a mode of normal use allowing a local replication of data in the second set of data storage and to address a distinct stream of commands and of data to each of the first and second memory controllers in a mode of remote replication.

Abstract: A method and device for allocating computer resources of a cluster for carrying out at least one job controlled by the cluster is disclosed. In one aspect, the method includes determining the placement of the job from physical features of the job and from physical features and availability of the computer resources of at least one processing area of the cluster. The method further includes receiving energy state features of the computer resources of at least the processing area; determining a recommended placement of the at least one job by correlating the physical features of the job, the physical features, availability and energy state of the computer resources on the basis of predetermined rules; and deducing, from the predetermined recommended placement, a recommended allocation list of the computer resources for carrying out the job in the cluster.
