The Most Manageable RAC Solution in the Industry
Certified by Oracle, VERITAS Storage Foundation
for Oracle RAC provides an integrated suite of Symantec technology
optimized for Oracle RAC. The solution includes of VERITAS
clustering, file system, and volume management technologies
allowing you to implement robust, manageable, and scalable
Oracle Real Application Clusters. The solution delivers
the industry’s first cluster file system supporting
Oracle RAC on the Solaris and HP-UX operating systems.
A cluster file system dramatically simplifies that installation
and ongoing management costs of an Oracle9i RAC environment.
Industry-Leading High-Availability Technology
VERITAS Storage Foundation™ for Oracle
RAC includes VERITAS Cluster Server™ technology.
VERITAS Cluster Server is the industy’s leading
open systems high availability technology with thousands
of customers.
In a VERITAS Storage Foundation for Oracle RAC environment, VERITAS Cluster Server provides a low latency interconnect to improve the performance and scalability of the Oracle CacheFusion technology. This technology runs on top of low cost, well understood, Ethernet connections, no proprietary interconnects are needed.
VERITAS Storage Foundation for Oracle RAC also includes I/O Fencing technology that prevents database corruption if a cluster split brain occurs. The VERITAS I/O Fencing implementation is the most robust in the industry, protecting aginst interconnect failures, interconnect timeouts, node hangs, and a varity of other failure mechanisms.
Clustered File System for Simplified Management
VERITAS Storage Foundation™ for Oracle
RAC provides a cluster file system (CFS) that has been
certified by Oracle to work with Oracle9i RAC. A CFS
simplifies the installation and ongoing management of
a RAC database. The VERITAS cluster file system provides
excellent I/O performance so you get the manageability
of a file system with no sacrifices in performance.
Installation is simplified because a single set of Oracle binaries can be installed and used on all nodes. Shared Oracle binaries also simplify the application of Oracle patches. This reduces the repetitive installation and updating work found in an environment without a CFS. Adding new Oracle data files is as simple as creating a new file, not the complication process of adding a new raw device.
The VERITAS CFS provides excellent I/O performance. All nodes in the cluster can directly read/write to the storage devices, there is no write-shipping being done over the inter-node connections. VERITAS takes advantage of the Oracle Disk Manager API for increased performance and manageability. The VERITAS CFS uses direct I/O bypassing file system locking and buffering. VERITAS CFS enables ease of management, without sacrificing I/O performance.
Flexible Storage Provisioning to Adapt to
Changing Business
VERITAS Storage Foundation™ for Oracle
RAC uses volume management technology to enable physical
disks to be managed as logical devices or volumes. The
clusterized volume manager included in this solution
provides flexible mirroring and striping configurations.
Multiple connections from servers to storage devices
further improve performance and availability. Online
administration allows administrators to reconfigure
the storage topology while RAC is up and running.
- Support for RAID 0, RAID 1, RAID 1+0, and RAID 0+1 increase performance and availability
- Online changes to size and layout of storage reduce planned downtime
