Setting the load balancing mode for a pool

A load balancing mode is specified as a pool attribute when a pool is defined

and may be changed by changing this pool attribute. For information about

configuring a pool, see Working with pools, on page 4-3. The following

example describes how to configure a pool to use Ratio Member load

balancing. Note that for Ratio Member mode, in addition to changing the

load balancing attribute, you must assign a ratio weight to each member

node.

Tip

The default ratio weight for a node is 1. If you keep the default ratio weight

for each node in a virtual server mapping, the nodes receive an equal

proportion of connections as though you were using Round Robin load

balancing.

To configure the pool and load balancing mode using the

Configuration utility

1. In the navigation pane, click Pools.

The Pools screen opens.

• If you are adding a new pool, click the Add button.

The Add Pool screen opens.

• If you are changing an existing pool, click the pool in the Pools

list.

The Pool Properties screen opens.

2. In the Add Pool screen or Pool Properties screen, configure the pool

attributes. For additional information about defining a pool, click

the Help button.

Note

Round Robin is the default load balancing mode and never needs to be set

unless you are returning to it from a non-default mode.

To switch a pool to ratio_member mode using the

Configuration utility

1. In the Current Members list, click the member you want to edit.

2. Click the Back button (<<) to pull the member into the resources

section.

3. Change or add the ratio value for the member.

4. Click the Add button (>>) to add the member back to the Current

Members list.

5. Click Done.
