## How Oracle Direct NFS works

Oracle Direct NFS (dNFS) bypasses the operating system’s buffer cache. Data is cached only once in the user space, eliminating the overhead of memory copies.

The following summary explains how Oracle Direct NFS works at a high level:

The traditional NFS client uses a single network flow, as the following example shows:

In contrast, Oracle dNFS improves performance by load-balancing network traffic across multiple network flows. This capability enables the Oracle database to dynamically establish a significant number of 650 distinct network connections, as shown in the example below:

The [Oracle FAQ for Direct NFS](http://www.orafaq.com/wiki/Direct_NFS) shows that Oracle dNFS is an optimized NFS client. It provides fast and scalable access to NFS storage that is located on NAS storage devices (accessible over TCP/IP). dNFS is built into the database kernel just like ASM, which is used primarily with DAS or SAN storage. As such, *the guideline is to use dNFS when implementing NAS storage and use ASM when implementing SAN storage.*
