This section describes how to set optimization service parameters for the HP EFS
WAN Accelerator. It includes the following sections:

‹ “Modifying In-Path Descriptions” on page 30
‹ “Configuring CIFS Protocol Support” on page 31
‹ “Configuring MAPI Protocol Options” on page 34
‹ “Configuring MS-SQL Protocol Options” on page 36
‹ “Enabling the NFS-Application Streamlining” on page 38
‹ “Modifying NFS Server Settings” on page 39

‹ “Enabling Transparent Prepopulation” on page 46
‹ “Enabling and Synchronizing Prepopulation Shares” on page 47
Enabling In-
Path and Out-of-
Path Support You can modify general in-path and out-of-path interface settings in the Optimization
Service - General Settings Page.
NOTE: You were prompted to enable in-path or out-of-path support when you completed the
installation wizard. This section describes how you can modify these settings.
The following types of deployments are available to you:
‹ Physical In-Path. The HP EFS WAN Accelerator is physically in the direct path
between the client and server. The clients and servers continue to see client and
server IP addresses. Physical in-path configurations are suitable for any location
where the total bandwidth is within the limits of the installed HP EFS WAN
Accelerator.
‹ Virtual In-Path. The HP EFS WAN Accelerator is virtually in the path between
the client and server. This differs from a physical in-path in that a packet
redirection mechanism is used to direct packets to HP EFS WAN Accelerators
that are not in the physical path. Redirection mechanisms include Web Cache
Communication Protocol (WCCP), Layer 4 (L4) switches, and Policy-Based
Routing (PBR). In this configuration, clients and servers continue to see client
and server IP addresses.
‹ Out-of-Path. The HP EFS WAN Accelerator is not in the direct path between the
client and the server. Servers see the IP address of the server-side HP EFS WAN
Accelerator rather than the client IP address, which might impact security
policies. An out-of-path configuration is suitable for data center locations where
physically in-path or virtually in-path configurations are not possible.
