Abstract

一种管理逻辑磁盘的性能方法及存储阵列。所述方法由存储阵列的控制器执行，所述存储阵列还包括内存、物理磁盘，所述物理磁盘上构建有多个逻辑磁盘。每个逻辑磁盘对应设定比例，所述设定比例为预设的每个逻辑磁盘的第一元数据中被加载至所述内存的第一元数据与每个逻辑磁盘的第一元数据的比例，每个逻辑磁盘的第一元数据为归属于每个逻辑磁盘的数据的元数据。所述方法包括当归属于被操作的逻辑磁盘的待操作数据的元数据待写入所述内存时，判断所述被操作的逻辑磁盘的第一元数据中被加载至所述内存的第一元数据与所述被操作的逻辑磁盘的第一元数据的当前比例是否达到所述被操作的逻辑磁盘对应的设定比例；当所述当前比例达到所述被操作的逻辑磁盘对应的设定比例时，利用内存淘汰算法将所述内存中的所述被操作的逻辑磁盘的部分第一元数据淘汰，并将所述待操作数据的元数据存储在所述内存中。
