Veritas Storage Foundation 5.1 SP1 for Oracle RAC Release Notes (5900-1513, April 2011)

The solution stack comprises the Veritas Cluster Server (VCS), Veritas Cluster
Volume Manager (CVM), Veritas Oracle Real Application Cluster Support
(VRTSdbac), Veritas Oracle Disk Manager (VRTSodm), Veritas Cluster File System
(CFS), and Veritas Storage Foundation, which includes the base Veritas Volume
Manager (VxVM) and Veritas File System (VxFS).
Benefits of SF Oracle RAC
SF Oracle RAC provides the following benefits:
■ Support for file system-based management. SF Oracle RAC provides a generic
clustered file system technology for storing and managing Oracle data files
as well as other application data.
■ Support for high-availability of cluster interconnects.
For Oracle RAC 10g Release 2:
The combination of LMX/LLT protocols and the PrivNIC/MultiPrivNIC agents
provides maximum bandwidth as well as high availability of the cluster
interconnects, including switch redundancy.
For Oracle RAC 11g Release 1/Oracle RAC 11g Release 2:
The PrivNIC/MultiPrivNIC agents provide maximum bandwidth as well as high
availability of the cluster interconnects, including switch redundancy.
■ Use of clustered file system and volume management technologies for
placement of Oracle Cluster Registry (OCR) and voting disks. These technologies
provide robust shared block and raw interfaces for placement of OCR and
voting disks. In the absence of SF Oracle RAC, separate LUNs need to be
configured for OCR and voting disks.
■ Support for a standardized approach toward application and database
management. A single-vendor solution for the complete SF Oracle RAC software
stack lets you devise a standardized approach toward application and database
management. Further, administrators can apply existing expertise of Veritas
technologies toward SF Oracle RAC.
■ Increased availability and performance using dynamic multi-pathing (DMP).
DMP provides wide storage array support for protection from failures and
performance bottlenecks in the HBAs, SAN switches, and storage arrays.
■ Easy administration and monitoring of SF Oracle RAC clusters from a single
web console.
■ Support for many types of applications and databases.
■ Improved file system access times using Oracle Disk Manager (ODM).
■ Ability to configure ASM disk groups over CVM volumes to take advantage of
dynamic multi-pathing (DMP).
