A method and apparatus for replicating a data container of a source storage server at the logical level in an unordered stream of individual data units are described. In certain embodiments, the replication operations can be performed without regard to the differences in geometry of physical persistent storage of the source and destination storage servers and without regard to the differences in data container format of the source and destination storage servers. An initial replication operation of the source data container is performed by transferring the data objects within the source data container to a replica data container in the destination storage server as an unordered stream of individual data units while preserving data object identifiers of the source data objects. Afterwards, incremental replication operations can be performed to capture modifications to the source data container over time after the initial replication operation.

Unordered idempotent logical replication operations

A method, non-transitory computer readable medium, and device that replicates data and provides instantaneous access to data includes receiving in a destination volume one or more named data extents and one or more references to the one or more named data extents associated with a file in parallel from a source volume. A determination is made to check whether the one or more references arrive before the one or more named data extents arrive. Each of the received one or more references which are determined to have arrived prior to the one or more data extents is allocated as absent by the storage management computing device. An instantaneous access to the file is provided during the allocation.

Methods for replicating data and enabling instantaneous access to data and devices thereof

The disclosed techniques enable push-based piggybacking of a source-driven logical replication system. Logical replication of a data set (e.g., a snapshot) from a source node to a destination node can be achieved from a source-driven system while preserving the effects of storage efficiency operations (deduplication) applied at the source node. However, if missing data extents are detected at the destination, the destination has an extent pulling problem as the destination may not have knowledge of the physical layout on the source-side and/or mechanisms for requesting extents. The techniques overcome the extent pulling problem in a source-driven replication system by introducing specific protocols for obtaining missing extents within an existing replication environment by piggybacking data pushes from the source.

Push-based piggyback system for source-driven logical replication in a storage environment

A copy-free transition tool converts storage objects from a source format associated with a source storage system to a destination format associated with a destination storage system. The transition tool exports configuration information associated with the source storage system to the destination storage system and brings the storage objects offline. Once the transition tool determines that the storage devices containing the storage objects are physically connected to the destination storage system, the tool can convert file systems from the source format to the destination format while leaving data and file layout unchanged. The tool can also modify metadata associated with each of the storage objects to conform to the destination format and store the modified metadata with the destination storage system.

Converting storage objects between formats in a copy-free transition

One or more techniques and/or systems are provided for incremental transfer with unused data block reclamation. For example, source volume of a source storage filer may have a physical replication relationship with a destination volume of a destination storage filer. Snapshots of a file system of the source volume may be used to identify new data blocks (e.g., data blocks allocated or reallocated to a new snapshot) and/or unused data blocks (e.g., data blocks of a deleted snapshot) used to incrementally update the destination volume so that the destination volume is a mirrored replication of the source volume. In this way, new data blocks may be updated and unused data blocks may be punched out (e.g., deallocated) of the destination volume during execution of an incremental update.

Incremental transfer with unused data block reclamation

Methods, non-transitory computer readable media, and computing devices that group objects with different service level objectives for an application includes receiving a request including a service level data to provision a volume. One or more aggregates for the received service level is identified. a resource pool including the identified one or more aggregates is generated. The volume including the generated resource pool with the identified one or more aggregates for the received service level is provisioned.

Methods for managing group objects with different service level objectives for an application and devices thereof

Presented herein are methods, non-transitory computer readable media, and devices for provisioning an application within a network storage system, which include: providing an application template; requesting input into the application template to construct the application in the network storage system and receiving the requested input; validating the input using standard templates for known applications stored within the network storage system; determining storage specifications within the network storage system based on the validated input; and creating storage and protocol objects associated with the application that identifies the storage specifications.

Application aware management in a network storage system

Presented herein are methods, non-transitory computer readable media, and devices providing an application centric view of storage within a network storage system, which include: creating an application instance, by the network storage system, wherein the application instance comprises at least one application-component determined based on application configuration information of the application instance; tracking the application configuration information of the application; and displaying the application configuration information in view of the storage within the network storage system.

Application granular reporting

A method, non-transitory computer readable medium and programmed apparatus that receives a request to replicate a volume from a source to a destination. The volume includes data and metadata including information descriptive of the data. The method includes determining a first set of blocks and a second set of blocks associated with the source, where the first set of blocks is associated with the metadata, and where the second set of blocks is associated with the data. The method includes initiating, based on the first set of blocks, replication of the volume from the source to the destination to generate a replicated volume at the destination. The replicated volume includes replicated metadata generated based on the replicated first set of blocks and includes absent allocated data corresponding to the data included in the volume storage at the source storage system.
