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 virtual in-
path configurations are not possible.
