摘要： An apparatus and method for referencing physical location of data objects stored within a logical container. The method may include receiving an access request from a client for a particular data object stored in a logical container having a plurality of data objects stored collectively in the logical container, and referencing a physical location of the particular data object within the logical container in response to the access request. The logical container includes at least one block, and each block of the logical container includes multiple extents to store data from at least one data object. The block is a fundamental unit of storage space.

摘要： A method of managing power states of memory modules while performing memory access operations is disclosed. Memory modules are in a power saving state until an access operation involving the module is to be performed. The module is placed in an operational mode, then the access operation is performed, then the module is returned to the power saving state. Apparatus and systems using the method are also disclosed and claimed.

摘要： Data with a short useful lifetime are received and cached by a system. The system waits for the first to occur of two events. If the first event is a local cache flush trigger, the data is written to a longer-term storage subsystem. If the first event is a remote cache flush trigger, the data is discarded. Systems and methods to benefit from this procedure are described and claimed.

摘要： A filer converts a traditional volume to a flexible volume by: creating an aggregate on storage devices other than the storage devices of the traditional volume; on the aggregate, creating a flexible volume large enough to store metadata describing files residing on the traditional volume; on the flexible volume, creating metadata structures that describe the files of the traditional volume, except that the metadata indicates that data blocks and indirect blocks are absent and must be fetched from another location. As the filer handles I/O requests directed to the flexible volume, the filer calculates physical volume block number (PVBN) addresses where the requested blocks would be located in the aggregate and replaces the absent pointers with the calculated addresses. After the absent pointers have been replaced, the filer adds the storage devices of the traditional volume.

摘要： The battery apparatus introduced here provides a tool for reliably measuring the run time to empty of a battery used in a network storage server for protection of data during a failure mode. The battery run time to empty can be determined by a management controller based on battery information generated by a controller and received at the management controller. The information received at the management controller includes run time to empty, voltage, current and current battery capacity.

摘要： In an RBAC system, a capability is defined as including an operation and an object on which the operation is to be performed. The capability is assigned to a role, which is in turn assigned to a user. Then the user will have the authorization to perform the operation on the object. Rather than specifying the object by predetermining the identity of the object, an expression (e.g., a regular expression, a query, etc.) may be specified in place of the predetermined object. In response to a request initiated by a user, the expression is then evaluated to determine the identity of the object(s) on which the operation may be performed.

摘要： A method and apparatus to generate information representing differences between two data sets are described. Information representing differences between a first data set and a second data set is acquired, where the first and second data sets each include multiple nodes. A traversal map that identifies nodes for which a difference has been detected between the first and second data sets is generated, and then during an output phase, a hierarchy of nodes is traversed to generate output indicating user-level differences between the first and second data sets. The traversal map is used to avoid traversing at least some of the nodes in the hierarchy during the output phase. A child map may be generated to represent parent-child relationships between the nodes and used during the output phase to prefetch certain nodes in the hierarchy.

摘要： A group of data storage units are serially connected in a sequential data communication path to communicate read and write operations to first and second interfaces of each data storage unit in the group. A data management computer device (“filer”) manages read and write operations of the data storage units of the group through an adapter of the filer. Main and redundant primary communication pathway connectors extend from the filer to the interfaces of the data storage unit, thereby establishing redundancy through multiple pathways to communicate the read and write operations to the data storage units of the group. Main and redundant secondary communication pathway connectors extend from partner filers to the groups of data storage units associated with each partner filer, thereby further enhancing redundancy.

摘要： A file server that provides for backup and restore of files in a heterogeneous file server environment. Metadata associated with each file by each model or protocol is preserved across backup and restore operations. The file server performs at least three tasks as part of the backup and restore operations. The file server notes all file attributes associated with each file in either model. These file attributes can include Unix perms, ownership and timestamp information, and link information. On backup, the file server records those file attributes in an analogous record using a different model. The file server records each element of Unix metadata as an NT Extended Attribute for use by an NT backup element. On restore, the file server restores those file attributes from the analogous record. The NT Extended Attributes provided by an NT restore element are translated into Unix metadata. The file server provides an element for translating between Unix metadata and NT Extended Attributes transparently to the NT backup and restore elements, so that NT backup and restore elements that were created without reference to the heterogeneous file server environment can be used.

摘要翻译： 一种文件服务器，用于在异构文件服务器环境中备份和还原文件。 每个模型或协议与每个文件相关联的元数据将跨备份和还原操作进行保留。 文件服务器至少执行三个任务作为备份和还原操作的一部分。 文件服务器注释与任一模型中的每个文件相关联的所有文件属性。 这些文件属性可以包括Unix perms，所有权和时间戳信息以及链接信息。 在备份时，文件服务器使用不同的模型将这些文件属性记录在类似的记录中。 文件服务器将Unix元数据的每个元素记录为NT扩展属性，供NT备份元素使用。 恢复时，文件服务器从类似的记录中恢复这些文件属性。 由NT恢复元素提供的NT扩展属性被转换为Unix元数据。 文件服务器提供了一种元素，用于将Unix元数据和NT扩展属性之间的数据透明地转换为NT备份和恢复元素，以便可以使用在不引用异构文件服务器环境的情况下创建的NT备份和恢复元素。
