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. Keys are stored in the Central Manager database which can be encrypted and synchronized among all Central Manager devices for high availability.
By following the recommended guidelines for performance and scalability, a robust Cisco Arcihtecture design can be realized, thereby allowing administrators to deploy the solution confidently to improve application performance over the WAN hardwsre enabling centralization and consolidation of costly infrastructure.
When a classifier match is found, the ATP examines the policy configuration for that classifier hardwaare determine how to optimize the flow. Allows a WAAS device to apply all the WAN optimization provided by the Transport license and all the application acceleration functionality with the exception of Video which is licensed separately.

The interface manager also provides management over logical interfaces that can be configured over physical interfaces. This can be coupled with a configuration that applies a specific DSCP marking to the packets within the flow.
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 Aand 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.

The distinction between the two is that a WAVE device, available only as an appliance, can also provide branch office virtualization services in conjunction with WAN optimization and application acceleration. 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 a LAN switch, similar to an appliance.
Each network module has a single hard disk with capacity ranging zrchitecture 80 to GB. Chapter Description This architetcure provides an introduction to the Cisco WAAS hardware family, along with an in-depth examination of the hardware and software architecture. The ISR is an ideal platform for the branch office in that it provides a converged service platform for the remote office, including routing, switching, wireless, voice, security, and WAN optimization in a single chassis platform, software version, and slot capacity dependent.
The Cisco WAE model WAE is a single-processor rack-mount system that is designed for deployment in small- and medium-sized branch office locations or small data center locations. Sample Chapter is provided courtesy of Cisco Press. Cisco WAAS also supports the definition of up to four syslog servers, which can be used as alarm recipients when syslog messages are wizing. The alarm book which covers syslog messages, SNMP traps, and Central Manager dashboard alarmserror book which covers console messagesarchtecture product documentation can be downloaded from Cisco.
It also looks at the licensing options for Cisco WAAS, positioning for each of anv hardware platforms, and performance and scalability metrics for each of the platforms.
About Affiliates Cisco Systems, Inc. The Cisco WAAS appliance family is designed to be deployed in a architeecture of any size, including the small branch office, campus networks, or the largest of enterprise data center networks. This chapter also looks at the licensing options for Cisco WAAS, positioning for each of the hardware platforms, and performance and scalability metrics for each of the platforms.
Each Cisco WAAS device, regardless of form factor, is configured with some amount of hard disk storage and a compact flash card. The WAE model is end-of-life and is not covered in this section; however, its performance architectre scalability metrics are covered waas this chapter to support those who have already deployed these devices in their networks and wish to continue using them with WAAS v4.

The ATP is consulted only during the establishment of a new connection, which is identified through the presence of the TCP synchronize SYN flag which occurs within the first packet of the architecure. 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.
WAVE appliance models and do not have externally accessible hard disk drives, and with a single hard disk drive, do not support RAID. Having a compact flash card enables the device to remain accessible on the network should the device suffer hard drive subsystem failure for troubleshooting and architectuge purposes in such a scenario, optimization and virtualization services would not be operational.
hatdware Router-Integrated Network Modules The Cisco WAAS router-integrated network modules are designed to provide optimization services for the remote branch office or achitecture edge. 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.
WAE appliance models andalong with WAVE appliance models, aarchitectureare targeted toward branch office deployments, whereas the WAE appliance models, are targeted toward regional office and data center deployments. Should a WAAS device be physically compromised or a disk stolen, power is removed from the device, which destroys the copy of the key in memory memory is not persistent. It also looks at the licensing options for Cisco WAAS, positioning for each of the hardware platforms, and performance and scalability metrics for each of the platforms.
With two drives, the system is configured automatically for software RAID
