AIX Protocol Performance Comparison With Oracle Database 11g Release 2
The protocols used in this paper are kernel Network File System (kNFS) and Oracle's new Direct NFS (DNFS) running over 10GbE connections, as well as IBM Enhanced Journaled File System (JFS2) and Oracle Automatic Storage Management (ASM) running over 4GB Fibre Channel (FC). This paper makes a distinction between two different network NFS clients. The NFS client provided by the AIX operating system is referred to as kernel NFS, or kNFS. The other NFS client, referred to as Oracle Direct NFS or DNFS, is a new NFS client provided by Oracle11g R2; it runs as part of the Oracle database. DNFS can be used only to access the Oracle database files.
