Equalizer can refuse an Add Site command for several reasons, including attempting to add:
• A site with a name or IP address that is already configured
• More sites than are supported by Equalizer
• A default site when you have already configured a default site
Adjusting a Site’s Static Weight
Equalizer uses a site’s static weight as the starting point for determining what percentage of requests
to route to that site. Equalizer assigns sites with a higher static weight a higher percentage of the
load. The relative values of site static weights are more important than the actual values. For
example, if two sites are in a geographic cluster and one has roughly twice the capacity of the other,
setting the static weights to 50 and 100 is equivalent to setting the static weights to 100 and 200.
Dynamic site weights can vary from 50% to 150% of the assigned static weights. To optimize
geographic cluster performance, you might need to adjust the static 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 geographic cluster, you should set
each site’s static weight value in proportion to its capacity for handling requests. It is not necessary
for all of the static weights in a cluster to add up to any particular number.
To change a site’s static weight, follow these steps:
1. Log into the Equalizer Administration Interface in edit mode.
2. In the left frame, click the name of the site to be modified. The site screen opens in the right
frame.
3. Select Change GeoSite Parameters from the local menu. The modify site screen appears in
the right frame.
4. Enter the new weight in the weight field.
5. Click the commit button.
Deleting a Site from a Geographic Cluster
To delete a site from a geographic cluster, follow these steps:
1. Log into the Equalizer Administration Interface in edit mode.
2. In the left frame, click the name of the site to be deleted. The site screen appears in the right
frame.
3. Select Delete this GeoSite from the local menu.
4. When prompted, click OK to confirm that you really want to remove the site.
