摘要： A system for responding to file system requests having file IDs comprising V, a volume identifier specifying the file system being accessed, and R, an integer, specifying the file within the file system being accessed. The system includes D disk elements in which files are stored, where D is greater than or equal to 1 and is an integer. The system includes a switching fabric connected to the D disk elements to route requests to a corresponding disk element. The system includes N network elements connected to the switching fabric. Each network element has a mapping function that for every value of V, specifies one or more elements from the set D that store the data specified by volume V, where N is greater than or equal to 1 and is an integer and N+D is greater than or equal to 3, which receives the requests and causes the switching fabric to route the requests by their file ID according to the mapping function. A method for responding to file system requests. The method includes the steps of receiving file system requests having file IDs comprising V, a volume identifier specifying the file system being accessed, and R, an integer, specifying the file within the file system being accessed at network elements. Each network element has a mapping function that for every value of V, specifies one or more elements from the set D that store the data specified by volume V. Then there is the step of routing the requests to a switching fabric connected to the network elements based on the file system request's ID according to the mapping function to disk elements connected to the switching fabric.

摘要： A technique provides an administrative path for accessing a writeable master storage volume in a mirrored storage environment. Illustratively, a writeable master storage volume stores a master set of data addressable by a corresponding pathname, and zero or more read-only (e.g., load-balancing) mirrored storage volumes are configured to store a mirrored set of the master set of data, the mirrored set also addressable by the corresponding pathname. Clients may read data from either the master storage volume or one of the mirrored storage volumes (e.g., according to a configured access location, such as a local mirrored volume if one exists) by issuing read requests having the corresponding pathnames. Also, each client may specifically access the master set of data from the master storage volume by issuing an access (e.g., read/write) request having a specified master storage volume pathname prefix prepended to the corresponding pathname.

摘要： The present invention provides a system and a method for utilizing a parity protection module to back up data on striped aggregates. Specifically, the system computes parity data for data stored at a particular location of each of a plurality of constituent aggregates, and stores the parity on one of the constituent aggregates that is a parity owner for that particular location of data. In the event one of the constituent aggregates fails, new data may still be accessed by the system (the striped aggregates), both to write new data, and to read data stored on the failed aggregate. In particular, the parity protection module allows clients to read data from a failed aggregate by running a reverse parity computation, which may also be used to restore the data to the failed aggregate.

摘要翻译： 本发明提供一种用于利用奇偶校验保护模块来备份条带聚集数据的系统和方法。 具体地，系统计算存储在多个组成聚合中的每一个的特定位置处的数据的奇偶校验数据，并且将奇偶校验存储在作为数据的该特定位置的奇偶校验所有者的组成聚合之一上。 在组合聚合中的一个失败的情况下，系统（条带聚合）仍然可以访问新的数据，无论是写入新数据还是读取存储在失败聚合中的数据。 特别地，奇偶校验保护模块允许客户端通过运行反向奇偶校验计算从故障聚合中读取数据，该反向奇偶校验计算也可用于将数据恢复到失败的聚合。
