Veritas File System 5.1 SP1 Administrator"s Guide (5900-1499, April 2011)

Clustered file systems are an extension of VxFS that support concurrent direct
media access from multiple systems.
■ Improved database performance
■ Cross-platform data sharing
Cross-platform data sharing allows data to be serially shared among
heterogeneous systems where each system has direct access to the physical
devices that hold the data.
See the Veritas Storage Foundation Advanced Features Administrator's Guide.
■ File Change Log
The VxFS File Change Log tracks changes to files and directories in a file
system.
■ Multi-volume support
The multi-volume support feature allows several volumes to be represented
by a single logical object.
■ SmartTier
The SmartTier option allows you to configure policies that automatically
relocate files from one volume to another, or relocate files by running file
relocation commands, which can improve performance for applications that
access specific types of files.
See the Veritas Storage Foundation Advanced Features Administrator's Guide.
Note: In the previous VxFS 5.x releases, SmartTier was known as Dynamic
Storage Tiering.
■ Storage Foundation Thin Reclamation
The Thin Reclamation feature allows you to release free data blocks of a VxFS
file system to the free storage pool of a Thin Storage LUN. This feature is only
supported on file systems mounted on a VxVM volume.
See the Veritas Storage Foundation Advanced Features Administrator's Guide.
■ Partitioned directories
The partitioned directories feature improves the directory performance of file
systems. This feature operates only on disk layout Version 8 or later file
systems.
Note: VxFS supports all HFS file system features and facilities except for the
linking, removing, or renaming of “." and “.." directory entries. Such operations
may disrupt file system sanity.
