HP Advanced Services zl Module with Microsoft® Windows Server® 2008 R2 Planning and Design Guide

2-5
Solution 1: WAN Optimization and Survivability
Solution Implementation
• Any additional interface modules the company requires for connec-
tivity
The switch in the example network is an HP E5406 zl switch.
 At the data center, a Riverbed Steelhead appliance
This solution is designed to fit seamlessly into the company’s existing network,
which, it is assumed, includes:
 WAN routers that connect the branch and data center
 Switches and routing switches at the branch and data center
 Domain controller and other servers at the data center
Solution Implementation
The following sections provide some basic guidelines for implementing this
solution as well as references to places where you can find more information.
You may need to adapt these guidelines to fit your particular network infra-
structure.
Predeployment Steps
By default, the server that runs on the module requests a DHCP address on its
internal interface 2. Network administrators can set the IP addresses manually
instead, or the DHCP server administrator can create a fixed DHCP reserva-
tion for the server. Generally, the first option is preferred. In this example, the
server has a static IP address at 10.10.5.2/24.
However, if you select the latter option, the server administrator should create
the reservation in advance. The administrator needs to know the MAC address
on the module’s internal interface 2. This MAC address is one higher than the
address listed on the label on module’s underside.
Branch HP zl Switch
You can configure whatever features your environment requires on the HP zl
switch that hosts the Advanced Services zl Module and the Riverbed zl module.
The sections below provide guidelines for the specific configurations required
by this solution.
