    摘要： Briefly, the present invention relates to an information dispersal sytem in which original data to be stored is separated into a number of data “slices” in such a manner that the data in each subset is less usable or less recognizable or completely unusable or completely unrecognizable by itself except when combined with some or all of the other data subsets. These data subsets are stored on separate storage devices as a way of increasing privacy and security. In accordance with an important aspect of the invention, a metadata management system stores and indexes user files across all of the storage nodes. A number of applications run on the servers supporting these storage nodes and are responsible for controlling the metadata. Metadata is the information about the data, the data slices or data subsets and the way in which these data subsets are dispersed among different storage nodes running over the network. As used herein, metadata includes data source names, their size, last modification date, authentication information etc. This information is required to keep track of dispersed data subsets among all the nodes in the system. Every time new data subsets are stored and old ones are removed from the storage nodes, the metadata is updated. In accordance with an important aspect of the invention, the metadata management system stores metadata for dispersed data where: The dispersed data is in several pieces. The metadata is in a separate dataspace from the dispersed data. Accordingly, the metadata management system is able to manage the metadata in a manner that is computationally efficient relative to known systems in order to enable broad use of the invention using the types of computers generally used by businesses, consumers and other organizations currently.

    摘要翻译： 简而言之，本发明涉及一种信息分散系统，其中要存储的原始数据被分成多个数据“切片”，使得每个子集中的数据不太可用或较少可识别或完全不可用或完全不可识别 本身除了与某些或所有其他数据子集结合在一起。 这些数据子集存储在单独的存储设备上，作为增加隐私和安全性的一种方式。 根据本发明的重要方面，元数据管理系统在所有存储节点之间存储和索引用户文件。 许多应用程序在支持这些存储节点的服务器上运行，并负责控制元数据。 元数据是关于数据，数据片或数据子集的信息以及这些数据子集在网络上运行的不同存储节点之间分散的方式。 如本文所使用的，元数据包括数据源名称，其大小，最后修改日期，认证信息等。该信息需要跟踪系统中所有节点之间的分散数据子集。 每次存储新的数据子集并且从存储节点中删除旧数据子集时，元数据将被更新。 根据本发明的一个重要方面，元数据管理系统存储用于分散数据的元数据，其中分散的数据是多个。 元数据位于与分散数据的单独数据空间中。 因此，元数据管理系统能够以相对于已知系统具有计算效率的方式来管理元数据，以便能够使用当前由企业，消费者和其他组织通常使用的计算机的类型来广泛使用本发明。

    摘要： An apparatus includes a processing module and a network interface. The processing module is operably coupled to obtain; a data storage transaction request regarding a file; determine identity of a user based on the data storage transaction request; access file level metadata based on the identity of the user to determine a plurality of file slices associated with the file; access file slice metadata to identify at least one of a plurality of storage nodes that stores or is to store, a data slice and coded subsets of at least one of the plurality of file slices; and generate a data storage transaction message to facilitate a data storage transaction regarding the at least one of the plurality of file slices. The network interface is operably coupled to convert the data storage transaction message into a network data storage message and transmit it.

    摘要： A computer a network interface and a central processing unit. The network interface communicates with a network. The central processing unit (CPU) is operable to receive a networked file system access request packet and to identify a root directory based on the networked file system access request packet. The CPU then identifies a file directory based on the root directory and the networked file system access request packet. The CPU then identifies file object metadata based on the file directory and identifies a set of slice servers based on the file object metadata and the networked file system access request packet. The CPU then issues, via the network interface, a set of commands to a set of slice servers regarding the networked file system access request packet.
