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

Personally, I'd choose ASM and recommend it to all my customers. This is partly because: 1) Oracle recommends it, 2) if Oracle recommends something, they generally support it better than things they don't recommend, 3) it doesn't cost extra money, and 4) I think ASM is a fine product that does its job well (admittedly better in 11g than 10g, but that's not your question). 

I think that using a CFS requires training for system admins while ASM would also require training, but possibly for the DBAs instead of the sysadmins. Typically, I still see ASM being managed by DBAs even though it really isn't a database. Many companies have the DBAs manage anything with the word Oracle stamped on it.

For docs or links, see otn.oracle.com/asm.

Folks
 

  
 

Additionally does ASM administration need additional Skill Set / Training versus administration
on Cluster File System(CFS), for RAC?
 

If so, in what context? 
 

  
 

Docs /
Links please?
 

  
 

Cheers
