Abstract

La présente invention porte sur un dispositif de stockage, un système de stockage et un procédé de transmission de données. Le dispositif de stockage comprend un premier contrôleur, un second contrôleur, une première carte d'échange, une seconde carte d'échange et un support de stockage. Le second contrôleur et le premier contrôleur se protègent l'un l'autre. La première carte d'échange est connectée au premier contrôleur. La seconde carte d'échange est connectée au second contrôleur. Le support de stockage est connecté au premier contrôleur et au second contrôleur. Le premier contrôleur est utilisé pour, après réception de premières données à stocker, calculer une informations de dispositif de stockage cible des premières données à stocker, et est utilisé pour, quand le dispositif de stockage cible n'est pas un dispositif de stockage, envoyer les premières données à stocker et l'information de dispositif de stockage cible des premières données à stocker par utilisation de la première carte d'échange. Le système de stockage peut comprendre de multiples dispositifs de stockage, et les multiples dispositifs de stockage forment un réseau en anneau.
