Oracle supports VCS control of RAC resources
Mostly for control of the Database instance, Listener and other resources should still be under CRS control, but can be under VCS if customer really wants it that way.

Resolving database transactions (replaying redo logs) to recover failed transactions during fail-over is a necessary step in any HA architecture. Log replay is likely to account for the bulk of recovery time.

Comparison of 3 different solutions to implement high availability for 3 Oracle databases:
Solution 1: Complete Oracle stack with RAC using ASM+CRS
-- When a node fails, at least 25% performance hit is taken, as 3 databases need to run on 3 nodes, but have not been tuned for running with less number of cpus.
“When RAC is running in an active-active configuration, service failover takes somewhat longer, possibly as long as other HA alternatives. “ – Tim Gorman, Oracle Expert
Solution2: Non RAC Oracle 10g HA solution in standby mode with CRS and ASM
CRS HA implies having a standby database instance for every node. So for a 3 database workloads you need to have at least 3 Active and 3 Passive nodes.
--CRS does not handle OS and hardware failures
Solution3: Non RAC Oracle 9i/10g HA solution in standby mode with SF Oracle HA
For planned server or instance outages (a.k.a. "maintenance"), RAC is not the very best HA alternative;
Databases: 3
Failover time: seconds
Performance Overhead: 15-25%
Databases: 3
Failover time: minutes
Performance Overhead: 0%
Databases: 3
Failover: Seconds to minutes
Performance Overhead: 0%

Storage Foundation for Oracle HA
Detects fault
Gracefully shuts down:
Application & database
Network resources
File system & storage resources
Migrates storage to standby
Starts resources on standby
Redirects traffic to standby
Can my application be clustered?
Application must be crash tolerant
Can restart to known point after single server crash
All data needed to restart stored on disk
Does not require shutdown to come back up properly
No need for “cluster aware” applications, simply well behaved applications
Most enterprise applications are completely cluster capable!

Summary
Symantec/Veritas and Oracle Together

35. Summary – SFOR/SFRAC value adds
Fully supports enterprise IT standardization – it is a complete solution
Fully supports any combination of Oracle single instance and RAC environments.
Includes DMP which provides the necessary functionality for load balancing and channel failover of storage resources
Includes intelligent storage management, as it has understanding and visibility of underlying physical disk in enterprise class storage environments such as Hitachi, EMC, and IBM Shark
Offers flexibility and granularity in laying out storage recognizing that dynamically changing environments will need i/o tuning from time to time.
Is a mature product (about 12 years old) that is endorsed for all environments including large scale ERP such as SAP.
Provides an infra-structure that facilitates DBAs, SAs, and Storage Admins working effectively and efficiently as a team to provide robust infra-structure for mission critical environments.
Provides robust (kernel level) cluster member management and performance/availability of cluster interconnect and CVM/CFS
Because the SFOR/SFRAC suite of products fully supports single instance Oracle as well as RAC, if you choose to deploy without RAC or with a mix of single instance and RAC, the very same infrastructure will meet your needs.
With the additional capabilities of VVR and GCO, a Highly Available solution can be architected for your Oracle environment to address not only HA, but DR as well!
