RE: Cluster File System Versus ASM for RAC Deployment in Production?... Pros & Cons

I think this is a big factor- VCS can cost a lot of money, while ASM is free.

OCFS2 has an advantage in one area- training, because it appears as a standard file system. Once you get past the initial install, it looks the same as a regular filesystem. Its also free.

ASM is reportedly faster that OCFS2 or cluster file systems, but I have not seen that in the real world (yet). Its also free.

Any new thing requires training. Big shops tend to use cluster file systems such as VCS for many other things like nfs, besides rac. So, if there is an expertise in VCS, and if they dont care much abt licensing costs, go ahead and use vcs.
