Preface Welcome to the Silver Peak NX Series Appliances Network Deployment Guide. Read the Preface to understand the target audience, the manual’s organization, related documents, and how to contact Customer Support. Who Should Read This Manual? This guide is written for network administrators who are familiar with administering and managing networks. Specifically, this guide provides an overview and summary of the most common deployment scenarios, followed by detailed and illustrated procedures for configuring and verifying each deployment. Because each enterprise’s network topologies and needs can differ, the network administrator needs to evaluate the environment and choose the deployment that best serves their needs. Silver Peak Systems’ support personnel are available to help you determine the best course of action. Because of this focus, this manual assumes that you are already familiar with the material covered in the Silver Peak NX Series Appliances Operator’s Guide. This includes basic installation procedures and how to use the Appliance Manager. Manual Organization This section outlines the chapters and summarizes their content. To keep things simple, we illustrate the examples with the typical in-line deployment in Site B offices and out-of-path deployment at Site A. However, Site B offices are not restricted to in-line deployment, nor is Site A restricted to out-of-path deployments. Chapter1, “Fundamentals of Deploying WAN Optimization,” describes some of the fundamental concepts of deploying WAN acceleration in enterprise networks. It provides an overview and introduction to common installation models, pros and cons of each, and recommendations. Chapter2, “Selecting a Silver Peak Deployment,” provides a summarized overview of the typical network deployments for the Silver Peak NX Series appliances. It also provides definitions of the common interfaces and terms used. Chapter3, “In-Line Deployment,” describes the procedures for an in-line deployment where the Silver Peak Appliance sits between the WAN router and the Ethernet switch. Chapter4, “Out-of-Path with Policy-Based-Routing Redirection,” describes the procedures for a scenario that deploys the Site B location in-line and the Site A network out-of-path with an available spare router port and uses Policy-Based Routing (PBR) on the WAN router to redirect traffic to the Silver Peak appliance. Chapter5, “Out-of-Path with WCCP,” describes the procedures for setting up Web Cache Coordination Protocol (WCCP) service. The example uses a Cisco router paired with a single Silver Peak appliance deployed out-of-path (Router mode). vii Silver Peak NX Series Appliances Network Deployment Guide Related Publications Chapter6, “Out-of-Path with VRRP Peering to a WAN Router,” describes the procedures for a scenario where the Silver Peak appliance uses the Virtual Router Redundancy Protocol (VRRP) to peer with the existing router, when no spare router port is available. Chapter7, “Out-of-Path with PBR and VRRP Redundant Silver Peak Appliances,” describes the procedures for setting up high availability. In this example, Site A deploys a primary and a secondary appliance out-of-path (Router mode), and the Site B location deploys the appliance in-line (Bridge mode). Additionally, the peered Site A appliances use the Virtual Router Redundancy Protocol (VRRP) to create and share a common IP address, called the Virtual IP address (VIP). Chapter8, “Out-of-Path with WCCP Redundant (Active/Active) Appliances,” describes the procedures for setting up high availability by using Web Cache Coordination Protocol with a Cisco router and redundant Silver Peak appliances in an out-of-path deployment. AppendixA, “Deployment Planning Aids,” provides a blank Configuration Worksheet where you can collect the IP addresses and other data needed for configuring the appliance(s) and deployment.
