Enabling Load Balancing

This topic describes how to link your load balancing hardware and software to an existing COS ConfigurationA logical grouping of devices, usually consisting of one or more COS - SDs and Testing Devices. A COS Configuration has two primary functions: It allows you to logically group Testing Devices and COS - SDs and it allows you to easily specify the settings for all of the devices in the COS Configuration..

1. After you complete the Configuration wizard for the first COS device by following the normal progression of steps, open your new COS Configuration by clicking on its name in the COS DashboardProvides visual status information for all COS Configurations, COS - SDs, and Testing Devices plus links that can be used to manage each COS Configuration, including COS - SDs and Testing Devices. and navigate to the Content HostingA COS - SD function used to provide content to student Testing Devices. Content Hosting authenticates content requests, decrypts content, and aggregates items into forms. page. From the Content Hosting page, perform steps 2-5.

2. Toggle Do you have a load balancer? to Yes.

3. Using the Load Balancer Service Device Manager drop-down menu, select which pooled COS - SDs will populate content into your shared storage location. Because you only added the first COS - SD to the pool, there will only be one choice. Later, you can add a different device and select one of them.

4. In the Load Balancer IP Address field, enter the internal IP address of your local load balancer. This IP address must be accessible from all of your Testing Devices.

   Note: The system automatically generates a fully-qualified domain name (FQDN) for your load balancer, displayed in the Load Balancer Hostname field for informational purposes only. You do not need to do anything with this value—COS automatically “points” the Testing Devices to this FQDN.

5. Click Update Configuration.
