Cisco WAAS Architecture, Hardware, and Sizing > Cisco WAAS Product Architecture
Each WAAS appliance has expansion slots to support one or more additional feature cards, such as the inline bypass adapter, which has two two-port fail-to-wire pairs. The current Cisco WAAS hardware family consists of three router-integrated network modules, two haddware appliance models, and four rack-mounted appliance models. Licenses are not enforced in WAAS; however, licenses can only be applied to platforms that support the particular license in question.
Summary The Cisco Wide-Area Application Engine family includes three network modules for the Integrated Services Router and six appliance models spanning two desktop models and four rack-mount appliance models. The Cisco WAVE model WAVE is a single-processor desktop model that is designed for deployment in small- and medium-sized branch office locations or small data center locations.
The ATP also notes the application group to which the classifier belongs to route statistics gathered to the appropriate application group for proper charting visualization and reporting.
As flows are intercepted by the WAAS device and determined architecfure be candidates for optimization, those flows are handed to the Application Traffic Policy ATP engine to identify what level of optimization and acceleration should be applied based on the configured policies and classifier matches.
Each Cisco WAAS device, regardless of form factor, is configured with some amount of hard disk storage and a compact flash card. When the hard disks are encrypted, loss of the key renders data on the disk unusable and scrambled. All relevant configuration, management, monitoring, and troubleshooting subsystems are made accessible directly through this CLI as opposed to exposing the Linux shell. Another wazs interface is the PortChannel interface, which can be used to team WAAS device interfaces together for the purposes of high availability and load balancing.
WAE devices provide only WAN optimization and application acceleration and do not provide virtualization. The configured policy dictates which optimization and acceleration components are enacted upon the flow and how the packets within the flow are handled.
Flows that do not have a match with an existing classifier are considered “other” traffic and are handled according to the policy defined for other traffic, which indicates that there are no classifier matches and that the default policy should be used.
It also anc at the licensing options for Cisco WAAS, positioning arxhitecture each of the hardware platforms, and performance and scalability metrics for each of the platforms.
The Cisco WAE model WAE is a dual quad-core rack-mount system eight processors that is designed for deployment in the largest of enterprise data centers and under hardward most demanding conditions. The Cisco WAAS appliance family is designed to be deployed in a location of any size, hardwafe the small branch office, campus networks, or the largest of enterprise data center networks. The compact flash card is used for boot-time operation and configuration files, whereas the hard disk storage is used for optimization data including object cache and Data Redundancy Elimination [DRE]swap space, software image storage repository, and guest operating system storage in the case of WAVE devices.
Cisco WAAS is a software component that is resident on a hardware device deployed at each location with users and servers. The WAAS VB architecture helps enable customers to further consolidate infrastructure by minimizing the number of physical servers required in the branch office for those applications which are not good candidates for centralization into a data center location.

WAVE appliance models and do not have externally accessible hard disk drives, and with a single hard disk drive, do not archihecture RAID.
Chapter Description This chapter provides an introduction to the Cisco WAAS hardware family, along with an in-depth examination of the hardware and software architecture. This should not imply that the device characterization presented is fixed; devices should be placed in locations according to performance and scalability sizing and feature requirements. Also, by using the hardaare flash card in this way, a WAAS device can successfully boot and become accessible on the network if no disks are available to the device.
Hardware Family Next Section. Settings configured in the policy are employed in hardwarr with one another.
The Cisco Cisco WAE model WAE is a sziing quad-core rack-mount system four processors that is designed for deployment in large enterprise data centers. Additionally, the increased memory configuration provides support for a greater amount of WAN bandwidth and optimized TCP connections. This license dictates what features are permitted to be configured on the device.

The interface manager also provides management over logical interfaces that can be configured over physical interfaces. This association is done by comparing the packet headers from each flow against a set of predefined, administratively configured, or dynamic classifiers, each with its own set sising one or more match conditions.
This can be coupled with a configuration that applies a specific DSCP marking to the packets within the flow. The Video license is commonly applied in wass with the Enterprise license.
The ATP is discussed in the next section, and Chapter 8 and Chapter 9 discuss the configuration and management of policies.
