Settings configured in the policy are employed in conjunction with one another. Cisco Linux provides an interface for the Cisco WAAS software to use for purposes of monitoring and generating alarms. WAAS devices configured with the Transport license cannot provide Enterprise license features including application-acceleration capabilities, hardwxre encryption, or any other features provided by other licenses. NOTE The WAE model is end-of-life and is not covered in this section; however, its performance and scalability metrics are covered in arcchitecture chapter to support those who have already deployed these devices in their networks and wish to continue using them with WAAS v4.

The WAE is a hybrid device that is commonly used for larger branch offices and those where virtualization is requiredbut works equally well as a data center device where virtualization is not used. This chapter provides an introduction to the Cisco WAAS hardware family, along with an in-depth examination of the hardware and achitecture architecture.
architecutre Each WAAS device includes two integrated Gigabit Ethernet interfaces including the network modules, one interface is internal and shares connectivity to a peer interface in the router through the router backplane, the other is external and can be cabled to archiecture LAN switch, similar to an appliance.
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.
Another logical interface is the PortChannel interface, which can be used to team WAAS device interfaces together for the purposes of high availability and load balancing. The disk encryption feature uses AES encryption, the strongest commercially available encryption, and keys are stored only in the WAAS device memory anr they have been retrieved from the Central Manager during the device boot process.
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. The WAE model is end-of-life and is not covered in this section; however, its performance and scalability metrics are covered in this chapter to support those who have already deployed these devices in their networks and wish to harddare using them with WAAS v4.

Any appliance model can be used as a core data center or edge branch office device, although performance and scalability waaa presented in this chapter must be followed. 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 looks at the licensing options for Cisco WAAS, positioning architectur each of the hardware platforms, and performance and scalability metrics for each of the platforms. 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. The interface manager also provides management over logical interfaces that can be configured over physical interfaces.

With such a diverse hardware portfolio, Cisco WAAS can be deployed in each location with the anr amount of optimization capacity for the needs of the users or servers in that particular location.
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. The alarm book which covers syslog messages, SNMP traps, and Central Manager dashboard alarmserror book which covers console messagescsico product documentation can be downloaded from Cisco. The Cisco WAAS product family consists of a series of appliances and router-integrated network modules that are based on an Intel x86 hardware architecture.
The Cisco WAAS appliance family is designed to be deployed in a location of any size, including the small branch office, campus networks, or the largest of enterprise data center networks.
The NME-WAE can be configured with the Enterprise license, providing full WAN optimization functionality, application acceleration functionality, and other features enabled by the Enterprise license including disk encryption and NetQoS integration.
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.

WAVE appliance models and do not have externally accessible hard disk drives, and with a single hard disk drive, do not support RAID. The Cisco Linux platform hosts a command-line interface CLI shell similar to that of Cisco IOS Software, which, along with the Central Manager and other interfaces, form the primary means of configuring, managing, and troubleshooting a device or architectture.
Performance and scalability metrics for each are examined later in this chapter, along with best practices around accurately sizing a Cisco WAAS deployment. These include disk encryption, Central Management Subsystem CMSinterface manager, reporting facilities, network interception and bypass, application traffic policy ATP engine, and kernel-integrated virtualization services, as shown in Figure Additionally, the Enterprise license enables support for disk encryption and NetQoS integration.

It hardwzre looks at the licensing options for Cisco WAAS, positioning for each of the hardware platforms, and performance and scalability metrics for waaas of the platforms.
Transaction logs are not covered in this book, but a full reference on their usage can be found in the Cisco WAAS documentation. Each Wxas 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 Cisco WAE model WAE is a quad-core rack-mount system that is designed for deployment in large branch office locations or medium to large data center locations.
architetcure With two drives, the system is configured automatically for software RAID It also looks at the licensing options for Cisco WAAS, cjsco for each of the hardware platforms, and performance and scalability metrics for each of the platforms.
By following the recommended guidelines for performance and scalability, a robust Cisco WAAS design can be realized, thereby allowing administrators to deploy the solution confidently to improve application performance over the WAN while enabling centralization and consolidation of costly infrastructure.
