Chapter 5 Configuring Virtual Servers

Configuring Virtual Servers

Load balancing using an existing sticky group 1. In the Server Farm field, select the primary server farm

1

to use for

load balancing. This must be the primary server farm specified in

the existing sticky group.

2. In the Backup Server Farm field, select the backup server farm

1

to

use for load balancing. This must be the backup server farm

specified in the existing sticky group.

3. In the Sticky Group field, select the sticky group to use.

Note Sticky groups appear in the Sticky Group field only when their

configured primary and backup server farms are selected,

respectively. If you select a sticky group and then select a

different primary or backup server farm, the sticky group that

you selected in the Sticky Group field no longer appears. To

change an existing sticky group configuration, modify it in the

Stickiness configuration screen (Config > Virtual Contexts >

context > Load Balancing > Stickiness).

Load balancing using a new sticky group

1. In the Server Farm field, select the primary server farm

1

to use for

load balancing, or select *New* to configure a new server farm (see

Table 5-11).

2. In the Backup Server Farm field, select the server farm

1

to act as the

backup server farm for load balancing if the primary server farm is

unavailable, or select *New* to configure a new backup server farm

(see Table 5-11).

3. In the Sticky Group field, select *New*, and then configure a new

sticky group using the information in Table 5-13.

Note The context in which you configure a sticky group must be

associated with a resource class that allocates a portion of ACE

appliance resources to stickiness. See the “Managing Resource

Classes” section on page 4-35 for more information on resource

classes.
