        Subject: Re: Cluster file systems versus raw devices in Oracle RAC                           i think that the only reason for using raw devices is if you don't have NAS for nfs or you dont have the cache to get a good CFS.

... great play on words :-) ! But let's think about this viewpoint. Hmmmm, the topic is CFS or RAW with RAC. I am astonished that after paying ~60K per CPU for RAC, why is paying some ~10% list for a really good general purpose and Oracle optimized CFS such a stumbling block? Sort of like paying for a fully loaded Mercedes, but shorting yourself on the air conditioning isn't it?
