HP StorageWorks Enterprise File Services WAN Accelerator 3.0.4 deployment guide (AG421-96001, March 2007)

24 2 - IN-PATH DEPLOYMENTS
Introduction to Physical In-Path Deployments
The following section describes physical in-path network configurations where the HP
EFS WAN Accelerator is physically in the direct path between clients and servers. The
clients and servers continue to see client and server Internet Protocol (IP) addresses.
Physical in-path configurations are suitable for locations where the total bandwidth is
within the limits of the installed HP EFS WAN Accelerator.

In-Path, Failover Support Deployment
An in-path, fail-over support deployment serves offices with one WAN routing point
and where network disruptions are unacceptable. This deployment is cost effective,
simple to manage, and continues to optimize data if there is an error in the system.
The following figure illustrates the client-side of the network where redundant HP EFS
WAN Accelerators are deployed to provide optimization of data.
