    • Systems and methods for, among other things, providing a storage system which allows for efficient tracking of in-use storage disk blocks using “sharing nodes”. Disk blocks are a result of low-level formatting, which breaks up the total storage capacity into a set number of blocks. High-level formatting of the disk creates the file system, and part of the file system may create metadata known as inodes, and associate an inode with each file, such that an inode tracks the disk blocks in use by that file, pointing from the file to a set of blocks. An S-node generator creates another type of metadata, complementary to an inode, known as an S-node data structure, such that an S-node data structure is associated with a block, and tracks the set of inodes using the block, pointing from the disk blocks to inodes.
    • 提供存储系统的系统和方法,其允许使用“共享节点”有效地跟踪使用中的存储磁盘块。 磁盘块是低级格式化的结果,它将总存储容量分解成一定数量的块。 磁盘的高级格式化创建文件系统,并且文件系统的一部分可以创建称为inode的元数据,并将一个inode与每个文件相关联,使得inode跟踪由该文件使用的磁盘块,指向 文件到一组块。 S节点生成器创建与称为S节点数据结构的inode互补的另一类型的元数据,使得S节点数据结构与块相关联,并且使用该块跟踪所述一组inode,指向 从磁盘块到索引节点。
