    • A memory management system for a thinly provisioned memory volume in which a relatively larger virtual address range of virtual address blocks is mapped to a relatively smaller physical memory comprising physical memory blocks via a mapping table containing entries only for addresses of the physical memory blocks containing data. The memory management system comprises a snapshot provision unit to take a given snapshot of the memory volume at a given time, the snapshot comprising a mapping table and memory values of the volume, the mapping table and memory values comprising entries only for addresses of the physical memory containing data. The snapshot is managed on the same thin provisioning basis as the volume itself, and the system is particularly suitable for RAM type memory disks.
    • 一种用于薄配置存储器卷的存储器管理系统,其中相对较大的虚拟地址块的虚拟地址范围被映射到包括物理存储器块的相对较小的物理存储器,所述物理存储器包括物理存储器块,该映射表仅包含仅包含数据的物理存储器块的地址的条目 。 存储器管理系统包括快照提供单元,用于在给定时间获取存储器卷的给定快照,快照包括映射表和卷的存储器值,映射表和存储器值包括仅针对物理地址的条目 包含数据的内存 快照以与卷本身相同的精简配置基础进行管理,并且该系统特别适用于RAM型存储磁盘。
