摘要:
In one embodiment, a data migration technique enables a source storage system to efficiently and reliably migrate data to a destination storage system. The source storage system includes a copy engine that is configured to migrate or copy a set of data, e.g., one or more files, to the destination storage system using a file-based protocol over a network. The copy engine is also configured to ensure that any locks associated with the migrated data set are reclaimed at the destination storage system using a lock-based protocol. The source storage system further includes a proxy service that is configured to translate client requests to access the migrated data set to access requests executable (i.e., discernable) by the destination storage system. The proxy service then forwards or proxies the translated requests over the network to the destination storage system for processing. In essence, the proxy service interacts with the copy engine to proxy protocol specific requests and replies between a client and the destination storage system after copying of the migrated data set has completed, thus rendering data migration transparent to the client.
摘要:
Method and system is provided for managing metadata for a plurality of data containers that are stored at one or more storage volumes in a clustered storage system. The metadata is collected from one or more storage volumes and then provided to a catalog module. The catalog module pre-processes the metadata and then generates a searchable data structure. The searchable data structure may then be used to respond to a user request for information regarding the storage system.
