摘要： A global namespace (GNS) is constructed across heterogeneous network-attached storage (NAS) devices by organizing metadata servers into a cluster layer having cluster nodes and a consistent hashing overlay layer having overlay nodes. The global namespace is distributed based on workload at the cluster and overlay nodes, and a portion of the GNS namespace may be migrated from one layer to the other. Cluster nodes may be added to the cluster layer, overlay nodes may be added to the consistent hashing overlay layer. Further, a cluster node may become an overlay node or an overlay node may become a cluster node. To access the global namespace, a request for namespace metadata managed by a cluster node is serviced by the cluster node, but if the requested namespace metadata have been migrated to the consistent hashing overlay layer, the cluster node will forward the request to the responsible overlay node for servicing.
摘要翻译：通过将元数据服务器组织到具有集群节点的集群层和具有覆盖节点的一致的散列覆盖层，跨异构网络连接存储（NAS）设备构建全局命名空间（GNS）。全局命名空间根据集群和覆盖节点的工作负载进行分布，一部分GNS命名空间可能会从一个层迁移到另一层。群集节点可以被添加到群集层，覆盖节点可以被添加到一致的散列覆盖层。此外，集群节点可以变为覆盖节点，或者覆盖节点可以成为集群节点。要访问全局命名空间，群集节点管理的命名空间元数据请求由群集节点服务，但是如果请求的命名空间元数据已迁移到一致的散列覆盖层，则群集节点将请求转发到负责的叠加层节点用于维修。

摘要： According to this invention, a computer system which provides a client node with a file system mounted into a virtual namespace, comprising: at least one file server which provides the file system; a root node which mounts the file system provided by the file server into the virtual namespace; and a network which couples the file server and the root node. The root node has an interface coupled to the network, a processor coupled to the interface, and a memory coupled to the processor. The root node is configured to: obtain access information set to a directory above a point in the virtual namespace at which the file system is to be mounted when mounting the file system into the virtual namespace; judge whether the obtained access information is to be inherited; and set, to the file system to be mounted, the obtained access information that is to be inherited.

摘要： A storage system configured to be applied to a broad range of access forms to the file and improve performance of file access control processing. The storage system may store a part of the access control information of a variable size in the basic attribute area of the file, and store the storage format information in the basic attribute area of the file or in the file system metadata area. At the time of processing the access to the file, with reference to the storage format information, the storage system may decode a part of the access control information into an access mask bit string as needed, and perform the preceding access control processing.

摘要： In the HSM function, when supporting the file system snapshot function, a differential data volume is required for both a high-speed volume and a low-speed volume. Accordingly, when supporting the snapshot function by using a file system provided by the HSM function, a large amount of differential data volume is required. When the manager gives an instruction to acquire a snapshot, a snapshot management program executes snapshot acquisition processing to acquire a snapshot. In this processing, a snapshot reference relation building processing part copies a file storage location management table, and relates the file storage location management table to the acquired snapshot. Then, the snapshot reference relation building processing part checks a file that is migrated to a file system which does not have a differential data volume. Finally, the snapshot reference relation building processing part creates a link of the migrated file to the snapshot which is acquired previous time.

摘要： The system of the present invention curbs an unnecessary inter-tier file migration and provides an inter-tier file migration that conforms to the utilization state. The hierarchical storage management system respectively migrates a frequently accessed file to the upper Tier, and an infrequently accessed file to the lower Tier. This system carries out inter-tier file migration in conformance with the utilization state. This system provides functions for anchoring a Tier for storage for a specified file, and for not permitting an inter-tier file migration.

摘要： Decrease in the write speed is prevented even when overwriting the entire file. When a NAS apparatus receives a file size change request from a computer as an access request source for changing the size of a file, the NAS apparatus creates a new file related to the file in a file system with a processing performance that is higher than a file system containing the file as an entity of that file, associates the new file and the foregoing file, deletes the file on the condition that the new file and the file has been associated, and executes data write processing of writing data into the new file on the condition of subsequently receiving a data write request from the access request source for writing data into the file.

摘要： A computer apparatus which integrates at least two or more services of user management domains has a processor, a memory and an interface. The processor receives an access request, specifies an access source domain, specifies an access target domain, and judges whether the specified access source domain matches the specified access target domain. If the access source domain is different from the access target domain, the processor extracts a user ID of the specified access source domain from the received access request, and refers to ID conversion information indicating correspondence of user IDs between the user management domains whose services are integrated to convert the extracted user ID of the access source domain into a user ID of the specified access target domain. Thus, loads of configuration at the time of service integration are reduced.

摘要： A file storage performs control to create a virtual parent file having an identifier capable of uniquely identifying a parent file among storage systems and volumes, and to acquire block layout information of the parent file using said identifier. The file storage creates a virtual parent file in the volume in which the clone file is created, and sets the file as a virtual parent file of the clone file so as to enable creation of a clone file of a parent file that exists in a different volume or a different storage system. Moreover, by combining creating the virtual parent file and switching the identifier of the parent file which is pointed by the virtual parent file, migration of clone files and parent files astride storage systems and volumes is enabled.
