NFS as unix service?

jpsingh · #1 (**permalink**) 3 Weeks Ago

Hi All

I want to understand the difference between 'NFS as a unix service' vs 'NFS attached to NAS' for the purpose of identifying shared storage solution for my test RAC setup. Oracle support says that 'NFS as unix service (what I understand is a local PC/server disk mounted as NFS) is not supported and that standard NFS client software (client systems that use the operating system provided NFS driver) is not optimized for Oracle database file I/O access patterns. But I still have my doubts that I can use this as a test setup? Please guide.

Also, it is said that with the introduction of Oracle 11g, a new feature known as Direct NFS Client integrates the NFS client functionality directly in the Oracle software. Through this integration, Oracle is able to optimize the I/O path between the Oracle software and the NFS server resulting in significant performance gains. Direct NFS Client can simplify, and in many cases automate, the performance optimization of the NFS client configuration for database workloads... does that mean I can use NFS as a unix service with oracle 11g?
