Abstract

o presente documento fornece um método para gravar dados para armazenamento em um meio de armazenamento com base em memória flash, o método sendo aplicado a um módulo de função de controle central para realizar o controle de gravação em pelo menos duas unidades de armazenamento físico. o método compreendendo: obtenção de uma contagem de apagamento cumulativa total de todos os blocos em cada uma das unidades de armazenamento físico (310); e gravação dos dados para armazenamento em pelo menos uma unidade de armazenamento físico com a contagem de apagamento cumulativa total mais baixa entre as unidades de armazenamento físico que satisfazem uma condição de gravação pré-definida (320). a solução técnica provê o apagamento e a gravação equilibrados entre diferentes unidades de armazenamento físico, evita danos prematuros em uma única unidade de armazenamento físico devido à realização de muitas operações de apagamento e gravação na unidade de armazenamento físico e melhora a estabilidade de um sistema onde a unidade de armazenamento físico está localizada em um cenário de alta disponibilidade.
