High-speed, object-based replication
Key Benefits:
- Replication Performance – Full replication performance typically improves by 2x to 3x with JetMirror. Incremental replication, especially at the scale of millions of small files or high rates of change, typically improves up to 25x over file-based replication methods.
- Improved disaster recovery – Object replication enables fast failover in the event of a disaster, without the need for the same hardware at both ends.
- Flexible deployment options – Object-based replication maintains the replication status on both the source and target file system, allowing replication to continue in the event of an interruption.
BlueArc JetMirror is a significant enhancement for data replication and disaster recovery at scale. It is enabled by the core technology in the object-based file system, BlueArc SiliconFS.
The BlueArc file system is object based; meaning that file system structures, metadata and user data are stored as objects, rather than as complete files or blocks. Object replication takes advantage of this structure to replicate these blocks natively, regardless of which file or directory that they may belong to. There is no need to assemble all of the objects associated with a file before transfer, making the overall transfer more efficient.
File-based replication must first walk the file system and process the file metadata in order to determine which blocks to transfer. For dense file systems, this can take significantly longer than block-based replication.
Block-based replication is known for being fast, but it is inefficient because there is no awareness of the block contents. For example blocks are replicated to the target where they consume space, even when they are empty.
BlueArc object-based replication is typically just as fast as block-based replication and often even faster. JetMirror delivers high-performance replication for disaster recovery at the scale of large, complex environments.
