Setting Optimization Services

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

‹“Enabling In-Path and Out-of-Path Support,” next

‹“Setting In-Path Rules” on page 25

‹“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 HSTCP Protocol Options” on page 42

‹“Enabling Connection Pooling” on page 44

‹“Enabling Transparent Prepopulation” on page 46

‹“Enabling and Synchronizing Prepopulation Shares” on page 47

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.
