Abstract: A manager program for managing virtual machines includes a process which receives a notification message indicating an occurrence of an event affecting a data storage unit in a data storage system that supports a shared file system. The notification message might have come from a virtual machine host or resulted from a hardware reconfiguration. The manager program then determines whether another virtual machine host is sharing the data storage unit. The manager program might make this determination by polling each of the virtual machine hosts it manages or by checking information previously collected and stored in a database. If another virtual machine host is sharing the data storage unit, the manager program sends a refresh message to that virtual machine host that causes the virtual machine host to update information relating to the data storage unit in a cache associated with the virtual machine host.

Abstract: Subsequent to a storage operation performed on the source instance by a source component, a synchronization message is sent to a replicated component for the replicated instance. The synchronization message is stored locally in a persistent storage location associated with the source component along with an indicator representative of a time the storage operation was performed. Pursuant to receipt of the synchronization message by the replicated component, the replicated component is updated to a dirty state to indicate a lack of full synchronization between the source and replicated instances. Receipt of the synchronization message is acknowledged by the replicated component by sending a dirty state acknowledgement. If, during a subsequent recovery process, the dirty state is not yet cleared, the replicated component is deemed ineligible for participation in a full restoration operation.

Abstract: Described herein are a system and method for remote mirroring of data and metadata from a local node to a remote node using out-of-order delivery (OOD), while also providing data integrity at the remote node. OOD may utilize increased throughput of multiple connection paths between nodes. A mirroring layer/engine executing on the local node may receive related groups of data and metadata for storing to the remote node, each related group comprising one or more data sets and one metadata set that describes and is associated with each of the one or more data sets in the related group. The mirroring layer provides data integrity at the remote node by ensuring that the metadata set of a related group is stored to the remote node only after all the data sets in the related group are stored to the remote node, thus ensuring data consistency at the remote node.

Abstract: A unified data access mechanism can provide transparent access to data that is either stored locally or remotely. Application programs can direct data requests and data modifications to this singular component without foreknowledge of where the data is stored. The unified data access mechanism can work in concert with a synchronization mechanism that can maintain data synchronization between local data and remote data. Requested or modified data can be identified as stored locally or remotely based on the namespace of the data. If the data is stored remotely, the user credentials associated with the user's process space within which the application program is executing can be utilized to identify, and then provide, relevant authentication information to the remote data store, should it be required.

Abstract: An application server in a multi-tenant computing system is enabled access to a first set of tables and views in a database according to a first schema. The views in the first schema correspond to a table in a second schema. Thereafter, the table in the second schema is modified to add a column. Views of the modified table as defined by the second schema are generated in a third schema so that the third schema defines a second set of tables and views in the database. Subsequently, access by the application server to the second set of tables and views in the database is enabled and access by the application server to the first set of tables and views in the database is prevented. Related apparatus, systems, techniques and articles are also described.

Abstract: A combination of synchronous and asynchronous replication of data is used to replicate a local database to a replicated database. The typical tradeoff between synchronous and asynchronous replication is optimized by using hybrid replication, which is to use synchronous replication for inserting new data and asynchronous replication for updating existing data. The combined use of synchronous and asynchronous in this manner provides an efficient replicated database where the replicated database can tolerate some delay in data updates but requires no data loss of new data.

Abstract: Various techniques for improving the performance of restoring deduplicated data files from a server to a client within a storage management system are disclosed. In one embodiment, a chunk index is maintained on the client that tracks the chunks remaining on the client for each data file that is stored to and restored from the storage server. When a specific file is selected for restore from the storage server to the client, the client determines if any local copies of this specific file's chunks are stored in files already existing on the client data store. The file is then reconstructed from a combination of these local copies of the file chunks and chunks retrieved from the storage server. Therefore, only chunks that are not stored or are inaccessible to the client are retrieved from the server, reducing server-side processing requirements and the bandwidth required for data restore operations.

Abstract: In response to a write command with regard to an FAT1 area received from a host device, the data storage apparatus collectively records management information with regard to the FAT1 area simultaneously with duplicate management information of identical content as management information with regard to an FAT2 area at consecutive addresses. In response to a write command with regard to the FAT2 area received from the host device subsequent to the write command with regard to the FAT1 area, the data storage apparatus notifies the host device of completion of data writing without recording the management information with regard to the FAT2 area. This arrangement effectively enhances the data writing efficiency in the data storage apparatus having multiple records of identical management information.

Abstract: Embodiments of the present invention relate to asynchronously replicating data in a distributed computing environment. To achieve asynchronous replication, data received at a primary data store may be annotated with information, such as an identifier of the data. The annotated data may then be communicated to a secondary data store, which may then write the data and annotated information to one or more logs for eventual replay and committal at the secondary data store. The primary data store may communicate an acknowledgment of success in committing the data at the primary data store as well as of success in writing the data to the secondary data store. Additional embodiments may include committing the data at the secondary data store in response to receiving an instruction that authorizes committal of data through a identifier.

Abstract: Presented herein are methods of replicating versioned and hierarchical data structures, as well as data structures representing complex transactions. Due to interdependencies between data entities and a lack of guaranteed message ordering, simple replication methods employed for simple data types cannot be used. Operations on data structures exhibit dependencies between the messages making up the operations. This strategy can be extended to various types of complex transactions by considering certain messages to depend on other messages or on the existence of other entries at the data store. Regardless of origin, these dependencies can be enforced by suspending the processing of messages with unsatisfied dependencies until all of its dependencies have been met. Alternately, transactions can be committed immediately, creating entities that include versioned identifiers for each of their dependencies. These entities can then be garbage collected of the parent objects are not subsequently created.
