We've got mostly 2 node (but also have a 6 and 4 node) clusters setup using
CRS. Oracle binaries on OCFS2. Storage on ASM. Multiple database in
active/passive mode on each cluster. This is all on Redhat Linux on
commodity hardware. Prior to that, we were on Solaris using Veritas file
systems. If a database crashed in the Solaris/Veritas environment, it would
take 45 mins for that server to reboot and mount all the file systems for
all the databases. With out current environment, there's no need to
mount/fschk file systems upon reboot so our failover time is usually less
than 5 mins. We also reduced the number of licenses needed by going from
the Solaris full license price to the 1/4 priced AMD's. Uptime has also
increased dramatically as the Sun 2900's and 6800's were not as fault
tolerant as advertised.
