CHAPTER 5 Configuring Connection

Forwarding

In This Chapter	This chapter describes how to deploy the HP EFS WAN Accelerator in asymmetric
	server-side networks using connection forwarding. This chapter includes the following
	sections:
	“Introduction to Connection Forwarding,” next
	“One-to-One Failover Deployment” on page 41
	“Configuring Connection Forwarding” on page 41
	This chapter assumes you are familiar with the HP EFS WAN Accelerator
	Management Console (Management Console). For detailed information about the
	Management Console and how to use it, see the HP Enterprise File Services WAN
	Accelerator Management Console User Guide.
	This chapter also assumes that you are familiar with the installation and configuration
	process for the HP EFS WAN Accelerator. For detailed information, see the HP
	StorageWorks Enterprise File Services WAN Accelerator Installation and
	Configuration Guide.

Introduction to Connection Forwarding

In asymmetric networks, a client request traverses a different network path than the server response. Although the packets traverse different paths, to optimize a connection, packets traveling in both directions must pass through the same client-side and server-side HP EFS WAN Accelerator.
