摘要： A primary processor manages metadata of a production dataset and a snapshot copy, while a secondary processor provides concurrent read-write access to the primary dataset. The secondary processor determines when a first write is being made to a data block of the production dataset, and in this case sends a metadata change request to the primary data processor. The primary data processor commits the metadata change to the production dataset and maintains the snapshot copy while the secondary data processor continues to service other read-write requests. The secondary processor logs metadata changes so that the secondary processor may return a “write completed” message before the primary processor commits the metadata change. The primary data processor pre-allocates data storage blocks in such a way that the “write anywhere” method does not result in a gradual degradation in I/O performance.

摘要： A protocol is provided for allocating file locking tasks between primary and secondary data mover computers in a network file server. When there is frequent read access and infrequent write access to a file, a primary data mover grants read locks to the entire file to secondary data movers, and the secondary data movers grant read locks to clients requesting read access. When write access to the file is needed, the read locks to the entire file are released and the read locks granted to the clients are released or expire or are demoted to non-conflicting byte range locks managed by the primary data mover. Concurrent read and write access to the same file is then managed by the primary data mover.
摘要翻译：提供了一种协议，用于在网络文件服务器中的主要和次要数据移动计算机之间分配文件锁定任务。当对文件进行频繁的读取访问和不频繁的写入访问时，主数据移动器将授予对整个文件的读取锁定到辅助数据移动器，次要数据移动器将向读取访问权限的客户端授予读取锁定。当需要对文件进行写入访问时，释放对整个文件的读取锁定，授予客户端的读取锁定将被释放或过期或降级到由主数据移动器管理的非冲突字节范围锁定。然后由主数据移动器管理对同一文件的并发读写访问。

摘要： Techniques are provided for storing files in a parallel computing system based on a user-specification. A plurality of files generated by a distributed application in a parallel computing system are stored by obtaining a specification from the distributed application indicating how the plurality of files should be stored; and storing one or more of the plurality of files in one or more storage nodes of a multi-tier storage system based on the specification. The plurality of files comprise a plurality of complete files and/or a plurality of sub-files. The specification can optionally be processed by a daemon executing on one or more nodes in a multi-tier storage system. The specification indicates how the plurality of files should be stored, for example, identifying one or more storage nodes where the plurality of files should be stored.

摘要： Improved techniques are provided for storing files in a parallel computing system using a list-based index to identify file replicas. A file and at least one replica of the file are stored in one or more storage nodes of the parallel computing system. An index for the file comprises at least one list comprising a pointer to a storage location of the file and a storage location of the at least one replica of the file. The file comprises one or more of a complete file and one or more sub-files. The index may also comprise a checksum value for one or more of the file and the replica(s) of the file. The checksum value can be evaluated to validate the file and/or the file replica(s). A query can be processed using the list.

摘要： Cloud infrastructure of an information processing system comprises one or more processing devices implementing a plurality of virtual machines. The cloud infrastructure is configured to receive a processing job from a tenant, to obtain a first key specific to the tenant, to determine a second key utilizing information supplied by the tenant, and to encrypt one or more results of the processing job utilizing a combination of the first key and the second key. At least a portion of the second key is determined by at least one application that is run on at least one virtual machine of the cloud infrastructure in conjunction with performance of the processing job. The encrypted results of the processing job may be stored in a virtual memory of the cloud infrastructure and transmitted to the tenant.

摘要： Servers in a storage system store a nested multilayer directory structure, and a global index that is an abstract of the directory structure. The global index identifies respective portions of the directory structure that are stored in respective ones of the servers, and the global index identifies paths through the directory structure linking the respective portions. Upon performing a top-down search of the directory structure in response to a client request and finding that a portion of it is offline, the global index is searched to discover portions of the directory structure that are located below the offline portion. The global index may also identify the respective server storing each of the respective portions of the directory structure, and may indicate whether or not each of the respective portions of the directory structure is known to be offline.

摘要： Embodiments of the present invention are directed to techniques for selecting a data path over which to exchange information between a client device and a storage system by making a selection between a file system server (NAS) data path type (a first data path type) and a direct (SAN) data path type (a second data path type) based on one or more adjustable path selection factors and/or information regarding components of the computer system. For example, a data path may be selected based on a type of an input/output operation to be executed (i.e., whether the operation is a read operation or write operation) and/or any other suitable path selection factor.

摘要： Network servers in a cluster share the same network protocol address for incoming client requests, and in a data link layer protocol a reply of a client to a request from a server is returned to this same server. For example: (1) ports of the servers are clustered into one single network channel used for incoming and outgoing requests to and from the servers; or (2) ports of the servers are clustered into one single network channel used for incoming requests to the servers and a separate port of each of the servers is used for outgoing requests from each of the servers; or (3) logical ports of the servers are clustered into one network channel used for requests to the servers and a separate logical port of each of the servers is used for outgoing requests from each of the servers.

摘要： A shallow file is adapted for intensive read-only access to data of a primary file. The primary file resides in another file system or file server. The shallow file includes the data block mapping metadata of the primary file and a link to the primary file. To open the shallow file, the file system manager of the shallow file obtains a read lock on the primary file from the file system manager of the primary file. Then the file system manager of the shallow file may use the data block mapping in the shallow file to access the file data from the primary file in storage without participation of the file system manager of the primary file. This permits offloading of data protection services for secure and efficient storage of a backup copy of the file data.
摘要翻译：浅文件适用于对主文件的数据进行强读取访问。主文件位于另一个文件系统或文件服务器中。浅文件包括数据块映射主文件的元数据和到主文件的链接。要打开浅文件，浅文件的文件系统管理器从主文件的文件系统管理器获取主文件上的读锁定。然后浅文件的文件系统管理器可以使用浅文件中的数据块映射来访问存储中的主文件的文件数据，而不需要主文件的文件系统管理器的参与。这允许卸载数据保护服务，以安全和高效地存储文件数据的备份副本。
