Veritas Volume Manager (VxVM) can improve system performance by optimizing the layout of data storage on the available hardware. VxVM lets you optimize data storage performance using the following strategies:
Balance the I/O load among the available disk drives.
Use striping and mirroring to increase I/O bandwidth to the most frequently accessed data.
VxVM also provides data redundancy through mirroring and RAID-5, which allows continuous access to data in the event of disk failure.
