    Your confusing Apples with Oranges. ASM is a database instance that allows your RAC or single instance database to seamlessly interact with a raw device in a clustered or non clustered file system. GPFS is one of IBM's ways of clustering the file system. They are complementary technologies (see Metalink NOTE:302806.1). If your going to run a RAC cluster then ASM is IMHO the way to go as it handles all of the mess with RAW devices for you and gives you the flexibility of a cooked file system with the speed & efficiency of RAW.

Subject: ASM Vs GPFS

Can somebody please provide some comparision of ASM and GPFS. There is big debate going on for Selecting ASM vas GPFS for Oracle 10g RAC on AIX server and I had to share some point to management and appreciate any link. Ofcourse ASM is free but SA are not ready to go with ASM and want to stick with GPFS. GPFS has some advatage like shared files etc. Even some DBA's are also inclined to GPFS as they have never worked with ASM aqnd also don;t want to try it. Management is ready to work based on unified solution with facts like big deployment using ASM or GPFS as well opinion of lots of technical community.
