Another logical interface is the PortChannel sizkng, which can be used to team WAAS device interfaces together for the purposes of high availability and load balancing. 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 disk encryption feature uses AES encryption, the strongest commercially available encryption, and keys are stored only in the WAAS device memory after they have been retrieved from the Central Manager during the device boot process.
WAAS devices configured with the Transport license cannot provide Enterprise license features including application-acceleration capabilities, disk encryption, or any other features provided by other hardwwre.
Licensing > Cisco WAAS Architecture, Hardware, and Sizing
This is defined in a single policy, thereby simplifying overall system policy management. The list of configurable elements within a policy include the following:. NOTE 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 continue using them with WAAS v4.
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 alarm book which covers syslog messages, SNMP traps, and Central Manager dashboard alarmserror book which covers console messagesand product documentation can be downloaded from Cisco.

This breadth of portfolio provides customers with the flexibility necessary to allocate the right aaas for each network location where WAN optimization, application acceleration, and virtualization capabilities are needed. This license dictates what features haardware permitted to be configured on the device.
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. 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 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 qaas physical interfaces. Licenses are not enforced in WAAS; however, licenses can only be applied to platforms that support the particular license in question. 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.

Any appliance model can be used as a core data center or edge branch office device, although performance and scalability recommendations presented in this chapter must be followed. By making a comparison against the ATP using the SYN packet of hardwarw connection being established, the ATP does not need to be consulted for traffic flowing in the reverse direction, as the context of the flow is established by all WAAS devices in the path between the two endpoints and applied to all future packets associated with that particular flow.
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. Hardware Family The current Cisco WAAS hardware family consists of three router-integrated network modules, two desktop appliance models, and four rack-mounted appliance models. The Video license is commonly applied in conjunction with the Enterprise license. 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 Sizihg devices.
Keys are stored in the Central Manager database which can be encrypted and synchronized among all Central Manager devices for high availability.
Cisco WAAS devices can be configured to encrypt the data, swap, and spool partitions on the hard disk drives using encryption keys that are stored on and retrieved from the Central Manager.
Both methods of integration and interception are discussed in Chapter 4.
Transaction logs are not covered in archotecture book, but a full reference on their usage can be found in the Cisco WAAS documentation. Sizing of a Cisco WAAS solution requires consideration of a number of factors, including network conditions WAN bandwidth and LAN throughputnumber of users and concurrent optimized TCP connections, disk capacity and compression history, memory, concurrently connected peers, and virtualization requirements.
The network interception and bypass manager is used by the Cisco WAAS device to establish relationships with intercepting devices where necessary and ensure low-latency bypass of traffic that the WAAS device is not intended to handle.
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 the most demanding conditions.
Cisco WAAS is a software component that is resident on a hardware device deployed at each location with users and servers. 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. The ISR is an ideal platform for the branch office in that it provides a converged service platform for the eizing office, including routing, switching, wireless, voice, security, and WAN optimization in a single chassis platform, software version, and slot capacity dependent.
