Abstract:
(EN) In a storage system in which computers are connected via a network, in order to avoid a state where communication quality is degraded due to poor performance of an apparatus constituting the network, for a transfer data amount, an amount of data sent out from a storage apparatus is suppressed. Moreover, the storage apparatus inhibits a read-ahead process, in accordance with the suppression of the sending out of the data. Furthermore, proper load allocation is realized by migrating a logical storage unit provided by the storage, to another network interface or a second storage apparatus, without changing a configuration of the network. (See Fig. 1)
(FR) Selon l'invention, dans un système de stockage dans lequel des ordinateurs sont connectés par l'intermédiaire d'un réseau, afin d'éviter un état dans lequel la qualité de communication est dégradée en raison du mauvais fonctionnement d'un appareil constituant le réseau, pour une quantité de transfert de données, une quantité de données envoyées d'un appareil de stockage est supprimée. De plus, l'appareil de stockage empêche un processus de lecture anticipée, conformément à la suppression de l'envoi de données. En outre, une attribution de charge appropriée est effectuée par la migration d'une unité de stockage logique fournie par le stockage, à une autre interface de réseau ou à un second appareil de stockage, sans changer la configuration du réseau.
