Overview
The Veritas File System (VxFS) is an extent-based, intent logging file system. VxFS is designed
for use in UNIX environments that require high performance and availability, and deal with
large volumes of data.
Currently, VxFS 5.0.1 is available on independent media only but may later be integrated into
the HP-UX 11i v3 Operating Environment, replacing the currently available VxFS 5.0. version.
New Features
The following new features are supported with VxFS 5.0.1 on the HP-UX 11i v3 operating system:
• The Direct I/O Feature
This feature now does not require the HP OnlineJFS license and is available in all HP-UX
Operating environments with the Base-VxFS bundle.
• The Concurrent I/O Feature
The concurrent I/O database acceleration feature was previously available with the SG-SMS
license. Starting with the VxFS 5.0.1 release, this feature is also available with the HP
OnlineJFS license and will continue to be available with the SG-SMS license.
• Setting Extent Attributes
This disk space management feature now does not require the HP OnlineJFS license and is
available in all HP-UX Operating environments with the Base-VxFS bundle
• Increased File System Size
The HP OnlineJFS license previously supported file systems of size up to 32 TB. Starting
with this release of VxFS 5.0.1, the HP OnlineJFS license supports file systems of size up to
256 TB.
• The SmartMove™ Feature
SmartMove reduces the time and I/O required to attach or reattach a plex to an existing
VxVM volume, in the specific case where a VxVM volume has a VxFS file system mounted
on it. The SmartMove feature uses VxFS information to detect free extents and avoids copying
them.
