摘要： Embodiments are directed to a unified and extensible telemetry method together with a data telemetry model aimed at the data activities of a system. Information collected using the telemetry data model is analyzed using telemetry analytics to derive insights on data activities, through the analysis of single events and subsequent linear relationships between these events, as well as the more generally networked multi-dimensional relationships among the data activities. Such analysis can provide insights for system owners to understand past data activities, optimize current data activities, and predict future data activity demands and requirements.

摘要： Embodiments of the present invention disclose a checkpoint reclaim method and apparatus in a copy-on-write file system. The checkpoint reclaim method includes: obtaining, according to a checkpoint reclaim instruction, M data blocks allocated by the file system between a moment of a previous checkpoint reclaim and a moment of a current checkpoint reclaim, where M is an integer not less than 1, and the M data blocks are data blocks allocated for at least one of a checkpoint or a snapshot generated between the moment of the previous checkpoint reclaim and the moment of the current checkpoint reclaim; performing an addition operation with a fixed step on a reference count of a data block that needs to be reserved in the M data blocks, and determining, in the M data blocks, a first data block that needs to be reclaimed; determining, in N data blocks allocated for at least one of a checkpoint or a snapshot reserved at the moment of the previous checkpoint reclaim, a second data block that needs to be reclaimed, where N is an integer not less than 1; and reclaiming the first data block and the second data block.

摘要： Various embodiments for managing migration between server systems are presented. Indications of a plurality of migration scripts to be executed during a migration of a database system from a source server system to a target server system may be received. An execution order for the plurality of migration scripts may be determined based upon characteristics of a plurality of database objects to be migrated using the plurality of migration scripts and characteristics of the plurality of migration scripts. Execution of a first migration script of the plurality of migration scripts may be initiated according to the determined execution order. The first migration script may cause copying of a database object of the plurality of database objects from the source server system to the target server system.

摘要： Various arrangements for performing an online migration between server systems is presented. A transfer, from a source server system to a target server system, of a database, may be initiated. During the transfer, the database of the source server system may remain online. A timing indication of when transfer of the database was initiated may be recorded. While transferring the database, modifications to the records of the database may be received. The plurality of modifications may be stored, and, for each modification of the plurality of modifications, a timing indication of when the modification was received may be stored. After completing the transfer of the database to the target server system, the plurality of modifications to the database stored by the target server system may be applied while the source server system is online.

摘要： A method and apparatus for rapid replication of deduplicated file system data is described. The method may include initiating replication of a file from a source deduplication system to a destination deduplication system, and transferring deduplication metadata for each block of the file from the source deduplication system to the destination deduplication system. The method may also include transferring an identifier file from the source deduplication system to the destination deduplication system that includes a block number corresponding to a block of the file and a unique identifier value generated from the block of the file. The method may also include receiving a data request file from the destination deduplication system, and transferring the blocks of data identified in the data request file to complete replication of the file on the destination deduplication system.

摘要： Systems and methods for data classification to facilitate and improve data management within an enterprise are described. The disclosed systems and methods evaluate and define data management operations based on data characteristics rather than data location, among other things. Also provided are methods for generating a data structure of metadata that describes system data and storage operations. This data structure may be consulted to determine changes in system data rather than scanning the data files themselves.

摘要： The present invention is directed to a system and method for transferring workload files on a host to a Virtual Machine (VM) destination disk without the need for the VM to be running. This accomplished by creating a VM disk device interface to move data from the workload files to the VM destination disk. The VM disk device interface comprises a device driver to interact with the VM destination disk and destination access software utilizing standard operating system procedures to access the VM destination disk.

摘要： There has never been disclosed a method of executing migration on a fine-grained basis than a file system basis in a manner that is transparent to clients in a storage system with a plurality of servers to which a global name space is applied. In a storage system with a plurality of servers (110A, 110B) and a disk subsystem (120), which is coupled to the plurality of servers, a file system in the disk subsystem is assigned a first identifier, which is unique throughout the storage system, at least one of directories contained in the file system is assigned a second identifier, which is unique throughout the storage system, and a file contained in the file system is assigned a third identifier, which is unique throughout the file system. The server identifies a file below the directory that has the second identifier by the second identifier and by the third identifier.
