Users and Servers. A site that has users and servers that are accessed remotely. Typically, users and servers are in a regional office with branch offices at remote sites that accesses data from remote sites and a data center.
2.Determine what kind of WAN routing infrastructure you have. For example, do you have one or two WAN routers?
3.How much bandwidth do you use? If you use large amounts of bandwidth, you need to consider deploying multiple HP EFS WAN Accelerators using a Layer-4 switch, Web Cache Communication Protocol (WCCP), or deploying HP EFS WAN Accelerators in a static cluster.
4.Choose a network template:
Physical In-Path. In a physical in-path deployment 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 any location where the total bandwidth is within the limits of the installed HP EFS WAN Accelerator. For detailed information, see Chapter 2, “In-Path Deployments.”
Virtual In-Path. In a virtual in-path deployment the HP EFS WAN Accelerator is virtually in the path between clients and servers. In a virtual in- path deployment, clients and servers continue to see client and server IP addresses. This deployment differs from a physical in-path deployment in that a packet redirection mechanism is used to direct packets to HP EFS WAN Accelerators that are not in the physical path of the client or server. Redirection mechanisms include Layer-4 switches, Web Cache Communication Protocol (WCCP), and Policy-Based Routing (PBR). For detailed information, see Chapter 3, “Virtual In-Path Network Deployments.”
Out-of-Path. In an out-of-path deployment the HP EFS WAN Accelerator is not in the direct path between the client and the server. In an out-of-path deployment, the HP EFS WAN Accelerator acts as a proxy. An out-of-path configuration is suitable for data center locations where physical in-path or virtual in-path configurations are not possible. For detailed information, see Chapter 4, “Out-of-Path Network Deployments.”
5.Determine how many HP EFS WAN Accelerators you need for your site:
One HP EFS WAN Accelerator is typically deployed in network environments with small to moderate bandwidth requirements.
Two HP EFS WAN Accelerators are deployed for redundancy in network environments where network outages cannot be tolerated.
Two HP EFS WAN Accelerators are deployed in network environments with multiple WAN links.
Multiple HP EFS WAN Accelerators are deployed in cluster configurations.
6.Do you have a firewall?
