E:Performance is improved by load balancing across multiple network interfaces (if available).
Note:
* To enableDirect NFS Client, you must replace the standard Oracle Disk Manager (ODM) librarywith one that supports Direct NFS Client.
Incorrect:
Not A:Direct NFS Client is capable of performing concurrent direct I/O, which bypasses any operating system level caches and eliminates any operating system write-ordering locks Not B:
*To use Direct NFS Client, the NFS file systems must first be mounted and available over regular NFS mounts.
*Oracle Direct NFS (dNFS) is an optimized NFS (Network File System) client that provides faster and more scalable access to NFS storage located on NAS storage devices (accessible over TCP/IP).
Not D:Direct NFS is provided as part of the database kernel, and is thus available on all supported database platforms - even those that don't support NFS natively, like Windows.
Note:
*Oracle Direct NFS (dNFS) is an optimized NFS (Network File System) client that provides faster and more scalable access to NFS storage located on NAS storage devices (accessible overTCP/IP). Direct NFS is built directly into the database kernel - just like ASM which is mainly used when using DAS or SAN storage.
*Oracle Direct NFS (dNFS) is an internal I/O layer that provides faster access to large NFS files than traditional NFS clients.
