Chapter 6 Configuring Real Servers and Server Farms
Configuring Dynamic Workload Scaling
Prerequisites
The ACE is configured to communicate with the local Nexus 7000 that enables the ACE to discover the
locality of the VM Controller VMs (see the “Configuring and Verifying a Cisco Nexus 7000
Connection” section on page 6-15).
Procedure
Step 1 Choose Config > Virtual Contexts > Load Balancing > Dynamic Workload Scaling > VM
Controller Setup.
The VM Controller Setup pane appears.
Step 2 From the VM Controller Setup pane, define the VM Controller using the information in Table 6-4.
Step 3 Click Deploy Now to deploy this configuration on the ACE and save your entries to the
running-configuration and startup-configuration files.
Note Configuring the ACE for Dynamic Workload Scaling also requires configuring the ACE with
the Nexus 7000 information (see “Configuring and Verifying a Cisco Nexus 7000 Connection”
section on page 6-15) and configuring a VM health probe (see the “Configuring Health
Monitoring” section on page 6-39).
Step 4 (Optional) Click Details to verify connectivity between the ACE and the remote VM Controller.
The ACE show vm-controller device_name detail CLI command output displays in a pop-up window
and includes VM Controller status, IP address, and connection information.
Step 5 (Optional) Click Delete to delete the currently configured VM Controller.
Note If the ACE is currently configured to use the Dynamic Workload Scaling, before you can delete
the VM controller, you must delete the associated VM health probe (see the “Configuring Health
Monitoring” section on page 6-39).
