Deployment Options

You can install all CA Network Flow Analysis components on a stand-alone system or can distribute the components among multiple servers:

A stand-alone system consists of a single, dedicated server or virtual machine that is used to install both the NFA console and the Harvester software.
A two-tier distributed deployment has the NFA console and one or more Harvesters installed on separate dedicated servers or virtual machines.
A three-tier distributed deployment has the NFA console, one or more Harvesters, and one or more Data Storage Appliances (DSAs) installed on separate dedicated servers or virtual machines.

The current version of CA Network Flow Analysis supports the following operating systems:

Microsoft Windows Server 2008 R2, Standard Edition on a 64-bit processor on any of the installation servers.
Red Hat Enterprise Linux 5.5 or 5.6 on a 64-bit processor on a Harvester server in a distributed deployment
