Abstract

método para melhorar a confiabilidade do sistema de armazenamento, e aparelho relacionado. um método para melhorar a confiabilidade de um sistema de armazenamento e um aparelho relacionado são fornecidos. o sistema de armazenamento inclui um primeiro dispositivo de controle e um segundo dispositivo de controle. o método inclui: receber, por um controlador alvo, uma solicitação de escrita, em que a solicitação de escrita inclui dados a serem escritos, e o controlador alvo pertence ao primeiro dispositivo de controle; escrever, pelo controlador alvo, os dados a serem escritos em uma memória do controlador alvo; e escrever, pelo controlador alvo, os dados a serem escritos em uma memória de um controlador espelho do controlador alvo, onde pelo menos um controlador espelho pertence ao segundo dispositivo de controle. de acordo com esta solução, os dados a serem escritos podem ser escritos e armazenados em dispositivos de controle. quando um dispositivo de controle está com defeito, um host pode ainda acessar outro dispositivo de controle, para garantir que um serviço não seja interrompido. isso melhora efetivamente a confiabilidade e a disponibilidade do sistema de armazenamento.
