Components of Veritas Storage Foundation for Oracle

Veritas Storage Foundation for Oracle combines the strengths of the core

technology products with database-specific enhancements to offer performance,

availability, and manageability for Oracle database servers.

Veritas Storage Foundation for Oracle includes the following products:

■ Veritas Volume Manager (VxVM)

A disk management subsystem that supports disk striping, disk mirroring,

and simplified disk management for improved data availability and

performance.

■ Veritas File System (VxFS)

A high-performance, fast-recovery file system that is optimized for

business-critical database applications and data-intensive workloads. VxFS

offers online administration, letting you perform most frequently scheduled

maintenance tasks (including online backup, resizing, and file system changes)

without interrupting data or system availability. VxFS also provides support

for large file systems (of more than 8 exabytes in a 64-bit environment) and

large files (in the exabyte range in a 64-bit environment).

Veritas File System offers the following performance-enhancing features that

are of particular interest in a database environment:

■ Veritas Quick I/O is a VxFS feature that improves the throughput for Oracle

databases built on VxFS file systems. Quick I/O delivers raw device

performance to databases run on VxFS, providing the administrative

advantages of using file systems without the performance penalties.

■ Veritas Cached Quick I/O further enhances database performance by

leveraging large system memory to selectively buffer the frequently

accessed data.

■ Veritas Concurrent I/O improves the performance of regular files on a VxFS

file system without the need for extending namespaces and presenting the

files as devices. This simplifies administrative tasks and allows relational

databases (such as Oracle), which do not have a sequential read/write

requirement, to access files concurrently.
