Marketing description

The Scalable File System Add-On for Red Hat Enterprise Linux uses the XFS file system to provide support for file systems that are between 16 terabytes and 100 terabytes in size. You can manage these large data stores using advanced features such as 64-bit journaling and advanced locking algorithms. In addition to supporting very large files and file systems on a single host, XFS also performs well on smaller systems running multi-threaded parallel I/O workloads.

Key selling points

• High performance - intelligent organization of file system metadata minimizes wasted space and generates lists of used and free space to speed write operations
• Quota support - project quotas can be used to restrict the amount of storage used by a given directory tree
• Online properties - common operations such as defragmentation and file system growth may be performed while the file system remains mounted
• Snapshots and backups - hardware snapshots can be facilitated by freezing an XFS file system while the snapshot is taken and backups can be made from live XFS file systems
