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.
