30 4 - OUT-OF-PATH NETWORK DEPLOYMENTS

Typically, in an out-of-path deployment, the client-side HP EFS WAN Accelerator is

configured as an in-path device, and the server-side HP EFS WAN Accelerator is

configured as an out-of-path device.

Figure 4-1. Physical Out-of-Path Deployment

Out-of-Path, Failover Deployment

An out-of-path, failover deployment serves networks where an in-path deployment is

not an option. This deployment is cost effective, simple to manage, and provides

redundancy.

In an out-of-path, failover deployment, two HP EFS WAN Accelerators are deployed.

When both HP EFS WAN Accelerators are functioning properly, the connections

traverse the master appliance. If the master HP EFS WAN Accelerator fails,

subsequent connections traverse the backup HP EFS WAN Accelerator.

When the master HP EFS WAN Accelerator is restored, the next connection traverses

the master HP EFS WAN Accelerator. If both HP EFS WAN Accelerators fail, the

connection is passed through unoptimized to the server.
