The disk encryption feature uses AES encryption, the strongest commercially available encryption, hhardware keys are stored only in the WAAS device memory after they have been retrieved from the Central Manager during the device boot process.
It also looks at the licensing options for Cisco WAAS, positioning for each of arhitecture hardware platforms, and performance and scalability metrics for each of the platforms. The Cisco WAAS router-integrated network modules are designed to provide optimization services for the remote branch office or enterprise edge.
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. Keys are stored in the Central Manager database which can be encrypted and synchronized among all Central Manager devices for architecrure availability.
This license dictates what features are permitted to be configured on the device.

When a classifier match is found, the ATP examines the policy configuration for that classifier to determine how to optimize the flow. Cisco WAAS also supports the definition of up to four syslog servers, which can be used as alarm recipients when syslog messages are generated. See All Related Articles.
The interface manager also provides management over logical interfaces that can be configured over physical interfaces. Allows a WAAS device to apply all the WAN optimization provided by architceture Transport license and all the application acceleration functionality with the exception of Video which is licensed separately.
Both methods of integration and interception are discussed in Chapter 4. The compact flash card is used for boot-time operation and configuration files, whereas the architectue 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.
This section examines the specifics of each of the current and legacy hardware platforms and positioning of each. Each WAAS appliance has expansion slots to support one or waaw additional feature cards, such as the inline bypass adapter, which has two two-port fail-to-wire pairs.
Additionally, the Enterprise license enables support for disk encryption and NetQoS integration. 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. In either configuration, the WAE can provide full WAN optimization and application acceleration capabilities, but does not support virtualization.

In addition, the ISR provides a strong foundation for application performance management APM solutions in that along with WAAS, other performance-related features can be configured, including quality of service QoS for network provisioning, Performance Routing PfR for optimal path selection and network utilization, and NetFlow for visibility into traffic distribution, throughput, and other metrics.
WAAS devices configured with the Transport license cannot provide Enterprise license features including application-acceleration capabilities, disk encryption, or any other features provided sizinh other licenses. 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.
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. 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. Licenses are not enforced in WAAS; however, licenses can only be applied to platforms that support the particular license in question.
The Adn appliance models, andalong with WAVE appliance modeleach have externally accessible hard disk drives and RAID support some models support hot-swappable disk drives.
The ATP is discussed in the next section, and Chapter 8 and Chapter 9 discuss the configuration and management of policies. This module is not capable of running the advanced services enabled by the Enterprise license discussed later in the chapterincluding application layer acceleration or disk encryption.
This breadth of portfolio provides customers with the flexibility necessary to allocate the right platform for each network location where WAN optimization, application acceleration, and virtualization capabilities are needed.
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.
This can be coupled with a configuration that applies a specific DSCP marking to the packets within the flow. The ATP is responsible for examining details of each incoming flow after being handled by the interception and bypass mechanisms in an attempt to identify the application or protocol associated with the flow.
Router-Integrated Network Modules The Cisco WAAS router-integrated network modules are designed to provide optimization services for the remote branch office or enterprise edge. 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. 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.
Return to Beginning Previous Section. Performance and scalability metrics for each are examined later in this chapter, along with best practices around accurately sizing a Cisco WAAS deployment. 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.
Hardware Family Next Section. Sample Chapter is provided courtesy of Cisco Press. 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. The product family scales from MB of memory to 24 GB of memory, utilizing single-processor subsystems up to dual quad-core processor subsystems.

Each network module has a single hard disk with capacity ranging from 80 to GB. Cisco Linux provides an interface for the Cisco WAAS software to use for purposes of monitoring and generating alarms. 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.

Licensing Next Section Previous Section. The Cisco Cisco WAE model WAE is a single quad-core rack-mount system four processors that is designed for deployment in large enterprise data centers. 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.
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 connection.
The reason for this level of configurability is the unique position of the WAE, which can be used for branch offices and data centers of virtually any size. With two drives, the system is configured automatically for software RAID
