11 - NETWORK FILE SYSTEM

PTIMIZATION

Basic Steps 1. Enable NFS in the Management Console Setup: Optimization Service - Protocol:

NFS page.

Enable NFS on all desired client and server HP EFS WAN Accelerators.

2. For each client HP EFS WAN Accelerator you desire, configure NFS settings that

apply by default to all NFS servers and volumes. For information, see the HP

Enterprise File Services WAN Accelerator Management Console User Guide

Configure these settings on all desired client HP EFS WAN Accelerators. These

settings are ignored on server HP EFS WAN Accelerators. If you have enabled

NFS optimization (as described in the previous step) on a server HP EFS WAN

Accelerator, NFS configuration information for a connection is uploaded from

the client HP EFS WAN Accelerator to the server HP EFS WAN Accelerator

when the connection is established.

IMPORTANT: If NFS is disabled on a server HP EFS WAN Accelerator, the applying will not

perform NFS optimization.

3. For each client HP EFS WAN Accelerator you desire, override global NFS settings

for a server or volume that you specify. You do not need to configure these settings

on server HP EFS WAN Accelerators. If you have enabled NFS optimization on a

server HP EFS WAN Accelerator, NFS configuration information for a connection

is uploaded from the client HP EFS WAN Accelerator to the server HP EFS WAN

Accelerator when the connection is established.

If you do not override settings for a server or volume, the global NFS settings are

used. If you do not configure NFS settings for a volume, the server’s specific

settings, if configured, are applied to the volume. If server-specific settings are

not configured, the global settings are applied to the server and its volumes.

NOTE: When you configure a prefetch policy for an NFS volume, you specify the desired

volume by file system identification (FSID) number. An FSID is a number NFS uses to

distinguish mount points on the same physical file system. Because two mount points on the

same physical file system have the same FSID, more than one volume can have the same FSID.

IMPORTANT: If NFS is disabled on a server HP EFS WAN Accelerator, the applying will not

perform NFS optimization.
