Active-Active Device Active-Active device allocation can only be performed when the Server Allocation Load Balancer has been configured to be redundant and active-active.

The Active-Active device allocation page allows you to allocate which services are currently active on the two redundant Server Load Balancers. You can allocate FTP to one Server Load Balancer and HTTP to the other. The two Server Load Balancers each provide only the allocated services, until a failover occurs.

To setup up a active-active device allocation, complete the following steps:

1Click Logical View on the Toolbar.

2Select Server Load Balancing > Active-Active Device. The Active-Active Device Allocation page is displayed.

3Choose the virtual host(s) you wish to change the position of.

4Click on the host and then click the appropriate arrow.

You are now ready to configure the load balancing services. See Chapter 8 Configuring for Load Balancing.
