Re: SGERAC over ASM
ServiceGuard with RAC is very reliable if configured correctly. It gives you high availability across multple systems. This reduces the number of single points of failure.
Statistically speaking that makes it more relaible than an app running on one system.
Note that newer versions of Oracle RAC have their own clustering system and don't need SG.

Re: SGERAC over ASM
You can install 10g RAC without SGeRAC, but, in this case, you won't have hardware protection, i.e., no lan cards failover, because 10g RAC doesn't care about hardware.
In speaking about ASM, it is not supported by SGeRAC'toolkit and if you want to configure ASM with SGeRAC, you MUST build your own start/stop script.
It doesn't mean that ASM is not reliable, I have a database of 1,2 TB with ASM and it's has been working for about 2 year without problems. In this case, we didn't use SGeRAC.

Re: SGERAC over ASM
Personally I prefer to have RAC without SGeRAC. However It is possible and reliable to have SGeRAC and ASM with together.
