Chapter 6 Configuring Real Servers and Server Farms
Configuring Server Farms
Adding Real Servers to a Server Farm
After adding a server farm, (see Configuring Server Farms, page 6-18), you can associate real servers
with it and configure predictors and retcode maps. The configuration screens for these attributes appear
beneath the Server Farms table or after you have successfully added a new server farm.
Note If you do not see these tabs beneath the Server Farms table, click the Switch between Configure and
Browse Modes button.
When creating or editing a server farm, if the real server to be added has the same name as an existing
global real server but contains a different IP address (or no IP address), the Device Manager displays the
following error message:
IP address of pre-existing real sever cannot be changed: “<rs-name>” (ip-addr>).
If this error message appears, ensure that you specify an existing real server with the matching IP
address.
Use this procedure to add real servers to a server farm.
Assumptions
• A server farm has been added to the ACE Appliance Device Manager. (See Configuring Server
Farms, page 6-18.)
• At least one real server exists.
Consideration
A server farm can support a mix of IPv6 and IPv4 real servers.
Procedure
Step 1 Choose Config > Virtual Contexts > context > Load Balancing > Server Farms. The Server Farms
table appears.
Step 2 Select the server farm you want to associate with real servers, and then select the Real Servers tab. The
Real Servers table appears.
Step 3 Click Add to add a new entry to the Real Servers table, or select an existing server, and then click Edit
to modify it. The Real Servers configuration screen appears.
