4. In both methods of creating GeoSite Instances the GeoSite IP Address is required. This is the IP address

returned by DNS to a client when the GeoCluster is accessed. For example, when a client opens

www.coyotepoint.com, the local DNS server returns an A record that contains the IP address for

www.coyotepoint.com. This is usually the address of an Equalizer cluster and in this case is also

used as the resource IP. However, the site’s A record IP may be different from the cluster (resource) IP if

the A record IP address is NAT’ed to an internal address (the actual cluster IP). In this case, you specify

the A record IP as the site IP and the cluster IP as the resource IP.

5. Using the slider on either form, adjust the Weight, which is an integer that represents the site’s capacity.

(This value is similar to a server’s initial weight.) Valid values range between 10 and 200. Use the default of

100 if all sites are configured similarly; otherwise, adjust higher or lower for sites that have more or less

capacity.

Equalizer uses a site’s initial weight as the starting point for determining what percentage of requests to

route to that site. Equalizer assigns sites with a higher initial weight a higher percentage of the load. The

relative values of site initial weights are more important than the actual values. For example, if two sites are

in a GeoCluster and one has roughly twice the capacity of the other, setting the initial weights to 50 and 100

is equivalent to setting the initial weights to 100 and 200.

Dynamic site weights can vary from 50% to 150% of the assigned initial weights. To optimize GeoCluster

performance, you might need to adjust the initial weights of the sites in the cluster based on their

performance.

Site weights can range from 10 to 200. When you set up sites in a GeoCluster, you should set each site’s

initial weight value in proportion to its capacity for handling requests. It is not necessary for all of the initial

weights in a cluster to add up to any particular number.

6. Click on Commit to add the GeoSite instance. The instance will appear beneath the GeoCluster on the left

navigational pane as shown below.

7. Select additional options for the GeoSite instance by clicking the GeoSite instance from the left

navigational pane to display the Configuration Required screen (tab).From this screen all configuration

options can be modified.
