Basic Steps
(Server-Side)
The server-side HP EFS WAN Accelerator is configured as an in-path device. For
detailed information, see the HP StorageWorks Enterprise File Services WAN
Accelerator Installation and Configuration Guide.
In-Path, Two Routing Points Deployment
An in-path, two routing point deployment serves offices with two WAN routing points
and redundant HP EFS WAN Accelerators. This deployment is simple to manage,
provides failover support, and load balances traffic.
For an in-path, two routing point deployment you must configure the Interior Gateway
Protocol (IGP) to prefer HP EFS WAN Accelerator links (links A, B in the figure
below) over non-HP EFS WAN Accelerator links for load balancing to occur. For any
given flow, under all conditions, both halves of the connection will use the same link
(A, B).
IMPORTANT: HP strongly recommends that you use a Four-Port Copper Gigabit-Ethernet
Bypass or connection forwarding for an in-path, two routing points deployment. For detailed
information about connection forwarding, see Chapter 5, “Connection Forwarding.”
The following figure illustrates the client-side of the network where two in-path HP
EFS WAN Accelerators are configured as in-path interfaces.
