Introduction to Out-of-Path Deployments
An out-of-path deployment is a network configuration in which the HP EFS
WAN Accelerator is not in the direct physical path between the client and the
server. In an out-of-path deployment, the HP EFS WAN Accelerator acts as a
proxy. An out-of-path configuration is suitable for data center locations where
physical in-path or logical in-path configurations are not possible.
