Chapter1 Introducing the Cisco Wide Area Application Engine
Introduction
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 WAE-7326 hardware supports installing (hot-swapping) hard disk drives
without powering off the device. However, Cisco software applications that run
on the WAE-7326 appliance do not support hot-swapping. You must reload the
WAE appliance before the software recognizes the new hard disk drives.
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.
