The VERITAS File System 3.5 (HP OnlineJFS/JFS 3.5) product is an extent-based,

The base VERITAS File System 3.5 (HP JFS 3.5) is a new version of the base journaled

Additional Support for Striping and Mirroring
new at 11i
original release
Logical Volume Manager (LVM) now supports striping and mirroring for shared volume
groups. Previously under HP-UX 11.0, a volume group could not be activated in shared
mode if any of its logical volumes were striped or mirrored. This restriction has now been
lifted.
Shared volume groups are provided to support ServiceGuard Oracle Parallel Server
(OPS), so this change only affects customers using OPS. Those customers are now free to
stripe their logical volumes (to improve throughput) or mirror them (for higher
availability).
NOTE Where performance is limited by I/O throughput, striping may help.
