Le procédé consiste : à détecter un premier hôte de service qui requiert un accès accéléré à une mémoire principale correspondante dans au moins un hôte de service (300) ; à établir une relation de connexion entre le premier hôte de service et un dispositif de mémoire accéléré lorsque le premier hôte de service est détecté (301) ; et à faire migrer des données stockées dans une première mémoire correspondant au premier hôte de service vers le dispositif de mémoire accéléré et à commander le premier hôte de service pour effectuer une commutation de données d'accès stockées dans une première mémoire principale à des données d'accès stockées dans le dispositif de mémoire accéléré (302), la vitesse de stockage du dispositif de mémoire accéléré étant supérieure à celle de la mémoire principale. De cette manière, un service d'accélération d'accès à des données peut être fourni pour chaque hôte de service qui nécessite une accélération d'accès à des données, permettant ainsi de résoudre le problème existant de limitations sur l'accélération de stockage.
