XtreemFS implements striping of files over several storage servers for increased I/O bandwidth and capacity. This is similar to RAID0. Parallel I/O ensures that read/write operations are executed in parallel on the storage servers to exploit the full link bandwidth.
Asynchronous MRC Backups
With asynchronous MRC backups you can easily create a consistent snapshot of your metadata without interrupting operations. The MRC will create the backup in background and continue to process client requests.
Asynchronous File System Snapshots
XtreemFS supports versioned files and asynchronous metadata snapshots. Together these two techniques allow you to create snapshots of a volume instantaniously.
Metadata Caching (client)
The XtreemFS client can cache metadata to speed up interactive use, e.g. from your shell. This feature is particularly useful if you mount volumes over the WAN or slow links like DSL.
