Setting Optimization Services
This section describes how to set optimization service parameters for the HP EFS
WAN Accelerator. It includes the following topics:
‹ “Enabling In-Path and Out-of-Path Support,” next
‹ “Setting In-Path Rules” on page 25
‹ “Configuring CIFS Protocol Support” on page 29
‹ “Configuring MAPI Protocol Options” on page 32
‹ “Configuring MS-SQL Protocol Options” on page 35
‹ “Enabling HSTCP Protocol Options” on page 37
‹ “Enabling Connection Pooling” on page 39
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. You can also limit connections on the client machine
that is initiating connections.
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.
If you have an HP EFS WAN Accelerator that contains multiple two-port or four-port
bypass cards, the Management Console displays options to enable in-path support for
these ports. The number of these interface options depends on the number of pairs of
Local Area Network (LAN) and Wide Area Network (WAN) ports that you have
enabled in your HP EFS WAN Accelerator.
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 may be suitable for data center locations
where physically in-path or virtually in-path configurations are not possible.
