Introducing the Cisco Wide Area Application Engine
This chapter provides a basic functional overview of the Cisco Wide Area Application Engine 7326 (WAE-7326), and describes the hardware, major components, and front and back panel indicators and controls.
This chapter contains the following sections:
•
Software Functional Description
Introduction
The Wide Area Application Engine (WAE-7326) supports three different software installations that provide a comprehensive set of services for the remote office: Cisco Wide Area Application Services (WAAS) software, Cisco Wide Area File System (WAFS) software and Cisco Application and Content Networking System (ACNS) software.
The following software releases support the WAE-7326 appliance:
•
•
•
When WAAS software is installed, the WAE appliance can function as either a Central Manager or as an Application Acceleration Engine. When ACNS software is installed, the WAE appliance functions as a Content Engine or one of the other ACNS device modes (Content Router or Content Distribution Manager). When WAFS software is installed, the WAE appliance functions as a File Engine. (See Figure 1-1.)
Figure 1-1 Wide Area Application Engine 7326—Front View
The WAE-7326 has a baseboard management controller that provides environmental monitoring for the appliance. If environmental conditions exceed thresholds or if system components fail, LEDs on the baseboard management indicate the problem. The error log also lists all critical errors. The baseboard management controller also provides remote server management capabilities through the OSA SMBridge management utility program.
Note
The WAE-7326 includes two integrated Broadcom Gigabit Ethernet controllers, which support connection to a 10-Mbps, 100-Mbps, or 1000-Mbps network.
The WAE includes large data-storage and hot-swap capability. The WAE-7326 supports up to six 25.4 mm (1-inch) slim, 3.5-inch hot-swap hard disk drives installed on Ultra-Slim hard disk drive trays in the hot-swap bays. With the hot-swap feature, you can add, remove, or replace hard disk drives without powering down the appliance.
Note
The Active Memory feature of your WAE-7326 improves the reliability of memory through memory mirroring and online spare memory. Memory mirroring stores data in two pairs of DIMMs simultaneously. Online spare memory disables a failed pair of DIMMs from the system configuration and activates a pair of online spare memory DIMMs.
Your WAE also includes a large system-memory capacity. The memory bus supports up to 16 GB of system memory. The memory controller supports error correcting code (ECC) for up to eight industry-standard, 1.8 V, 240-pin, double-data rate (DDR) II, PC3200, registered SDRAM DIMMs.
The addition of an optional network interface card (NIC) in the WAE-7326 provides a failover capability to a redundant Ethernet connection. If a problem occurs with the primary Ethernet connection, all Ethernet traffic associated with this primary connection is automatically switched to the redundant Ethernet connection. If the applicable device drivers are installed, this switching occurs without data loss and without user intervention.
The WAE-7326 supports up to two Intel Xeon microprocessors. If the appliance comes with only one microprocessor, you can install an additional microprocessor to enhance performance and provide symmetric multiprocessing (SMP) capability.
Software Functional Description
The operation of the WAE is dependent on the software application that is installed on it. This section describes WAAS, ACNS and WAFS software:
WAAS Software Description
With WAAS software installed, the WAE appliance functions as either a WAAS Central Manager or a WAAS Application Acceleration Engine. The WAAS Central Manager provides a graphical user interface to monitor and configure all Acceleration Engines. The WAAS Acceleration Engine is deployed in remote branch offices and in the data center to accelerate TCP applications that access data across the network.
The Application Acceleration Engine functionality operates at different levels based on the software licenses purchased. WAAS 4.x, software offers the WAAS Transport License or the WAAS Enterprise License options.
Cisco WAAS software helps enterprises meet the following objectives:

ACNS Software Description
With ACNS software installed, the WAE appliance functions as a Content Distribution Manager, Content Engine, or Content Router. The Content Distribution Manager provides a graphical user interface to manage registered Content Engines and Content Routers. The ACNS solution addresses the need to distribute and receive high-bandwidth, media-rich content across the Internet or an intranet without performance losses or content-delivery delays.
ACNS software offers the following content-based services:
•
•
•
•
In Content Engine mode, the WAE operates either as a component of an ACNS network or as a standalone content-caching device and is generally positioned on the WAN edge between your enterprise network and the Internet.
Note
To deploy Cisco Content Engines with Cisco ACNS software within your existing network, your network must support Cisco IOS software and the Web Cache Communication Protocol (WCCP). WCCP transparently redirects HTTP requests to a Content Engine, and the Content Engine responds to those requests.
WAFS Software Description
With WAFS software installed, the WAE appliance functions as a File Engine. The File Engine is an Internet file delivery device that provides the following file-based services:

Ethernet Port Connectors
Connect a Category 3, 4, or 5 unshielded twisted-pair cable to this connector. 100BASE-TX and 1000BASE-T Fast Ethernet standards require Category 5 or higher cabling.
The WAE-7326 has three Ethernet connectors. Two of the Ethernet connectors are attached to the Ethernet controllers. The Ethernet controllers are integrated on the system board. They provide an interface for connecting to a 10-Mbps, 100-Mbps, or 1-Gbps network and provide full-duplex (FDX) capability, which enables simultaneous transmission and reception of data on the network. If the Ethernet ports in the server support auto-negotiation, the controllers detect the data-transfer rate (10BASE-T, 100BASE-TX, or 1000BASE-T) and duplex mode (full-duplex or half-duplex) of the network and automatically operate at that rate and mode. You do not have to set any jumpers or configure the controllers. However, you must install a device driver to enable the operating system to address the controllers.
The third Ethernet connector is the Remote Supervisor Adapter II SlimLine Ethernet connector. Use this connector to enable remote server management through a network. This connector is active only if an optional Remote Supervisor Adapter II SlimLine is installed.

Serial Port Connector
Your WAE has one serial port connector. Use the serial port connector to connect a serial device.
Figure 1-7 Serial Port Connector
Ultra320 SCSI Controller System Board Connectors
The WAE-7326 has one SCSI LVD port connector located on the back panel. The integrated dual-channel SCSI controller with integrated RAID supports two independent Ultra320 SCSI channels: one external and one internal. Each channel supports up to 15 SCSI devices. You can use the external LVD SCSI channel connector on the rear of the server to connect different types of SCSI devices, such as drives or printers.
This controller uses the following features to perform these actions:
•
•
•
•
The WAE-7326 has one SCSI cable, which connects the internal connector on the system board to the standard hot-swap-drive backplane. If you plan to attach external SCSI devices, you must order additional cables. To select and order the correct cables for use with external devices, contact your Cisco marketing representative or authorized reseller.
SCSI IDs
Each SCSI device that is connected to a SCSI controller must have a unique SCSI ID. This ID enables the SCSI controller to identify the device and ensures that different devices on the same SCSI channel do not attempt to transfer data simultaneously. SCSI devices that are connected to different SCSI channels can have duplicate SCSI IDs. Table 1-5 lists the SCSI IDs for the hard disk drives and backplanes that are connected to one channel.

Fibre Channel Connector
The Fibre Channel connector is an LC-style connector that supports non-OFC, multimode fiber-optic cabling using a small form factor (SFF) fiber-optic transceiver module. The Fibre Channel adapter uses LC-LC Fibre Channel cables. Total cable length cannot exceed 1640 feet (500 meters). Fibre Channel cables are not supplied by Cisco Systems.
Inline Network Adapter Description
This section describes the following features of the WAE inline network adapter:
•
•
For adapter specifications, see Table A-3 in Appendix A.
Form and Function
Your appliance supports one optional 4-port Ethernet inline network adapter. The inline network adapter is a full-height, three-quarter-length PCI-X network interface card that contains four independent Gigabit Ethernet ports. (See Figure 1-9.)
Figure 1-9 Inline Network Adapter
The Cisco WAE inline network adapter provides inline traffic interception capability for your appliance. When your appliance is configured for inline interception mode, you can set attributes to control which interfaces are to be used over which VLANs. By default, the adapter operates on all inline-capable interfaces and VLANs. You can configure the inline redirection feature using the WAAS 4.0.7 CLI or the WAAS 4.0.7 Central Manager GUI.
The WAAS software defines two new interface types: A group interface that represents an inline pair grouping and a port interface that represents the individual port. These interfaces are referred to as inlineGroup and inlinePort, respectively.
InlineGroup interfaces are numbered using the format slot/group. The slot number is the slot in which the adapter is inserted. (In the WAE 500 series and 600 series appliances, the adapter must be installed in slot 1 only.) The group number is either 0 or 1 (each adapter has 2 group pairs). The group number is displayed on the adapter label.
InlinePort interfaces are numbered slot/group/lan or slot/group/wan. The last attribute is the LAN or WAN designator.
The inline network adapter also includes an onboard programmable Watch Dog Timer (WDT) controller. You can set the time to wait after a failure event, such as a power outage or a kernel crash, before the unit begins to operate in mechanical bypass mode. In mechanical bypass mode, traffic is bridged between the LAN and WAN ports of each group. Mechanical bypass mode prevents the WAE from becoming a single point of failure and allows traffic to continue to flow between the router and the client while it passes through an unresponsive WAE without being processed.
For more information about configuring the inline network adapter, see the Cisco Wide Area Application Services Configuration Guide.
Ports and LED Indicators
Figure 1-10 shows the inline network adapter port numbers, interface designations, and LEDs. Table 1-6 describes the LED functions.
Figure 1-10 Inline Network Adapter Port Numbering and LEDs
Port 0; Group 1 WAN interface
Port 1; Group 1 LAN interface
Port 2; Group 0 WAN interface
Port 3: Group 0 LAN interface
The inline network adapter has three LEDs that correspond to each port (the 0 LEDs correspond to Port 0, and so forth). Table 1-6 describes the LEDs.
Inline Network Adapter Cabling Requirements
Your inline network adapter ships with two types of cables: crossover and straight-through. When you connect the WAE inline network adapter, proper cabling depends on the link speed (Gigabit Ethernet or Fast Ethernet) and the types of devices (DCE or DTE) being connected.
Note
If you are connecting a WAE inline appliance between two devices using Gigabit Ethernet, you can use either straight-through cables, crossover cables, or any combination of the two cable types, regardless of the type of device. However, for consistency, we recommend that you use straight-through cables for all Gigabit Ethernet connections.
Table 1-7 shows the cable requirements for WAE and non-WAE connections when you are using Gigabit Ethernet end to end.
Some switches support automatic medium-dependent interface crossover (MDIX). You can configure MDIX by using the mdix auto global configuration switch command. If your switch supports MDIX, you do not need to follow these cabling rules because MDIX automatically adjusts transmit and receive pairs when an incorrect cable type (crossover or straight-through) is installed on a 10/100 Fast Ethernet port. However, when you configure MDIX, you must also configure the port to use autosense (not manual selection of speed/duplex).
Caution
To connect the inline network adapter using the correct cables for Fast Ethernet connections, follow these steps:
Step 1
•
•
Note
Table 1-8 shows the cable requirements for WAE and non-WAE connections when you are using Fast Ethernet end to end.
Step 2
•
•
For example, if you are connecting a router and a switch (two different devices) through the WAE inline appliance, use a straight-through cable on the LAN side of the connection and use a crossover cable on the WAN side of the connection. (If you were connecting the two different devices directly, you would use a straight-through cable, so use the crossover cable instead.)
If you are connecting two switches (or two similar devices), use straight-through cables on both the LAN and the WAN sides of the WAE inline appliance.
Figure 1-11 through Figure 1-13 show the cables to use for the WAE LAN and WAN connections between Fast Ethernet ports.
Installation Scenarios and Cabling Examples for Fast Ethernet Connections
WAE appliances can be installed physically between two network devices (such as the branch office router and branch office LAN switch) by connecting the WAE inline network adapter ports to the network devices using the proper cables.
If you are connecting a WAE inline appliance between two devices using Gigabit Ethernet, you can use either straight-through cables, crossover cables, or any combination of the two cable types, regardless of the type of device. This section shows cabling examples for Fast Ethernet connections only, because Fast Ethernet has specific cabling requirements.
The inline network adapter has four ports that are divided into two inline groups (see the "Ports and LED Indicators" section). The WAE can be physically placed inline between two distinct network paths, creating redundant WAN links. (See Figure 1-11.)
Two WAEs with inline network adapters can also be installed back-to-back in a serial fashion between two network devices for failover purposes. In this type of serial cluster configuration, if one WAE fails, the other WAE can provide optimization. (See Figure 1-12.)
