Citrix ADC pooled capacity on Citrix ADC instances in cluster mode

You can configure Citrix ADC pooled capacity on the Citrix ADC instances configured as a cluster. Following are the prerequisites for configuring pooled capacity on Citrix ADC instances in cluster mode:

Instances should be individually running in a pooled-capacity license mode to form the cluster.
All the instances should be running with same bandwidth.
All the instances should check out the pooled capacity from the same Citrix Application Delivery Management (ADM).
New instances cannot be added to an existing Citrix ADC cluster unless their capacity and Citrix ADM configurations are same as those of the existing instances in the cluster.

Any capacity check-out from the Citrix ADC cluster will assign same capacity to all the cluster nodes and the checkout Bandwidth = Bandwidth provided * number of nodes.

For example, if you check-out 50 Mbps of bandwidth from the Citrix ADC cluster, and the cluster includes 12 instances, each instance automatically receives 50 Mbps; and 600 mbps is checked out from the pool.

Note

If one or more instances in the cluster become unresponsive, the cluster continues to work with the capacity of the remaining instances.

To allocate Citrix ADC Pooled capacity on Citrix ADC instances in cluster mode:

In a web browser, type the IP address of the Cluster IP (CLIP) address (for example, http://192.168.100.1).
In the User Name and Password fields, enter the administrator credentials.
On the Configuration tab, navigate to System > Licenses > Manage Licenses, click Add New License, and select Use Pooled Licensing.
Enter the name or address of the license server in the Server Name/IP Address field.
If you want to manage your instance’s pool licenses through Citrix ADM, select the Register with Citrix ADM for manageability check box and enter the ADM credentials.
Select the license edition and the required bandwidth, and click Get Licenses.
You can change or release the license allocation by selecting Change allocation or Release allocation.
If you click Change allocation, a pop-up window shows the licenses available on the license server.

Note

Bandwidth allocation must be an integral multiple of the minimum bandwidth unit of the corresponding form factor.
You can allocate bandwidth or instances to the Citrix ADC instance from the Allocate drop-down list. Then click Get Licenses.
You can choose the license edition and the bandwidth required from the drop-down lists in the pop-up window.

Note

A restart is not required if you change the bandwidth allocation, but a warm restart is required if you change the license edition.
