摘要： Volume configuration data management systems and methods are described. A logical volume provider maintains an epoch number on each of the extents comprising a volume. Upon each change in the configuration of the volume, the epoch number on each of the currently online extents is updated. When a volume is discovered and a request is made to bring the volume online, the logical volume provider can compare the epoch numbers on the extents to determine if the volume data is consistent across each of the extents, or if an extent contains stale data due to a transitory outage.

摘要： Techniques are described for providing client computing nodes with enhanced access to data from remote locations, such as by providing and using local capabilities specific to the remote locations. In at least some situations, the access of a client computing node to data from a remote location may be enhanced by automatically performing activities local to the client computing node that improve the efficiency of communications sent between the client computing node and the remote location. As one example, access to data from a remote service may be enhanced by locally performing activities specific to the remote service, such as by using information about the remote service's internal mechanisms to cause the desired data to be provided from internal storage devices of the remote service without passing through front-end or other intermediate devices of the remote service while traveling to the client computing node.

摘要： An improved hierarchical storage management (HSM) system used in connection with computer systems is provided. A technique is provided whereby a file having portion(s) migrated to remote storage location(s) may be efficiently relocated, and metadata for the file is updated according to its relocated storage relationships. Thus, when a source file having portions migrated to remote storage is to be re-located or copied by the HSM system to a target file, instead of copying the entire file across all of its associated storage locations, the minimum or efficient set of data is relocated. The metadata describing the source file's migration storage characteristics is updated to reflect its new use in connection with the target file.

摘要： Debug controls for debugging a distributed application are included in messages that are also used by the distributed application to transport data. A debug initiator causes debug controls to be inserted in the header portion of a message that is being transported across a distributed system. The debug initiator may insert debug controls directly or may cause a message router that receives the message to merge debug controls into the message. The message router may receive debug controls from the debug initiator or from configuration files that are maintained at the message router. The message, which now includes distributed application data and debug controls, is routed to a message recipient. The message recipient accesses the message to identify debug functions that are to be performed at the message recipient. The message recipient performs at least one of the identified debug functions.

摘要： A system, a method, and program products for buffering data from a file in a hierarchical data storage system allocates data buffers and buffer management structures in memory to optimize performance of no recall requests. Buffer management structures, such as buffer headers and hash queue headers, are used to optimize performance of insert, search, and data buffer reuse operations. Buffer headers are managed in a least-recently-used queue in accordance with a relative availability status. Buffer headers are also organized in hash queue structures in accordance with file-based identifiers to facilitate searching for requested data in the buffers. Data buffers can be used to buffer different data blocks within the same file and can be recycled to buffer data from other data blocks and other files from the secondary storage device. Data in a data block may be reread by the requesting process or by other processes as long as the requested data remains valid. Lock fields are used to coordinate multi-thread and multi-user accesses.

摘要： Information regarding volume mount points hosted by a logical volume are stored on the physical device underlying the logical volume so that the relationships between the host logical volume and target logical volumes mounted on the volume mount points can be reconstituted when the system containing the logical volumes is rebooted, when the underlying physical devices are moved with the system, and when the logical volumes are transported to a different system. A data structure stored on the physical device contains the directory name of the volume mount point and the unique identifier and a globally unique mount name of the target logical volume mounted at the volume mount point. When the target logical volume is present in the system, symbolic links are created to relate the volume mount point name to a device name for the target logical volume so that pathnames containing the directory junction name are resolved correctly. If the target volume is not present in the system, the corresponding symbolic link does not exist, so an incorrect logical volume cannot be mounted onto a volume mount point. Furthermore, because the logical volumes contain the directory junction information, the namespace representing the logical volumes is self-describing so that neither user knowledge nor intervention is required to reconstitute the namespace.
摘要翻译：有关由逻辑卷托管的卷安装点的信息存储在逻辑卷底层的物理设备上，以便在包含逻辑卷的系统为包含逻辑卷的系统时，主机逻辑卷与安装在卷安装点上的目标逻辑卷之间的关系可以重新构建当底层物理设备与系统一起移动时，以及何时将逻辑卷传输到其他系统时重新启动。存储在物理设备上的数据结构包含卷安装点的目录名称和唯一标识符以及安装在卷安装点的目标逻辑卷的全局唯一安装名称。当系统中存在目标逻辑卷时，会创建符号链接，以将卷安装点名称与目标逻辑卷的设备名称相关联，以便正确解析包含目录结名的路径名。如果系统中不存在目标卷，则相应的符号链接不存在，因此不正确的逻辑卷无法挂载到卷安装点上。此外，由于逻辑卷包含目录结点信息，表示逻辑卷的命名空间是自描述的，因此不需要用户知识和干预来重构命名空间。

摘要： The present invention relates to systems and methods for archiving or backing up data. The systems and methods use a staging area to temporarily store data prior to transfer to backup or archive storage. Data is copied from local storage to the staging area and stored there temporarily until it is transferred to backup or archive storage. The staging area preferably uses sparse file technology which stores a mixture of zero data and non-zero data in a storage space substantially equal to the storage space required to only store the non-zero data. Once data is transferred from the staging area to remote storage, the storage space allocated in the staging area may be deallocated in order to minimize the amount of storage space required for the staging area. In addition, the local storage space may also be deallocated, if appropriate. Using sparse file technology as the staging area results in minimal storage requirements and minimal overhead for managing the storage space of the staging area.

摘要： An apparatus, a method, and a computer program product conceptually provide a logical unit of undivided data storage that spans physical storage device boundaries. The apparatus manages the logical unit of undivided storage using metadata information stored on the physical storage devices. Advantageously, the apparatus replicates a minimum portion of the metadata information across all of the data storage devices and favors writing metadata only in the devices where the information is required to operate. In a preferred embodiment, a logical unit of undivided storage is created by defining a logical volume and allocating portions of available physical data storage devices thereto in order to provide a minimum logical volume size. Metadata is generated and stored on the data storage devices to provide detailed information about the portions of each data storage device that have been allocated to the logical volume. After initialization, the size of the logical volume can be automatically changed such that portions of the data storage devices are allocated to or deallocated from the logical volume. Following an allocation or deallocation operation, the metadata stored on the data storage devices is minimally updated only on the data storage devices affected by the operation. The metadata on unaffected storage devices is not changed such that processing time is improved. In another embodiment, the metadata may be differentiated into two types, global and local. Global metadata is maintained in a fully replicated way across all of the data storage devices. Local metadata containing information specific to a particular data storage device is maintained on that storage device but is not replicated on other storage devices. In this way, data storage space availability is improved. In still another embodiment, an in-memory data structure is constructed to maintain information derived from the stored local metadata. Full operation is possible despite failed or unavailable physical data storage devices.

摘要： An apparatus and method is disclosed for scheduling a service (such as backup) in a complex computer installation given constraints of elapsed time and resource utilization. The apparatus form of the invention has two major components: a Modeler and a Scheduler. The Modeler calculates utilization of computer installation resources and elapsed time for the service for any subset of clients and/or networks using a model of the various client types, network types and their interconnections. The Scheduler invokes the Modeler with subsets of clients to find utilizations and elapsed times and adjusts the subsets to generate a schedule (if one exists) which is a list of subsets of clients which can be serviced concurrently without exceeding the utilization criterion or an elapsed time criterion. The Scheduler uses a heuristic involving client and network types to rapidly converge on the list of subsets of clients for the schedule to greatly improve over a trial and error approach.
