NetScaler Pooled capacity on NetScaler instances in cluster mode

You can configure NetScaler Pooled capacity on the NetScaler instances configured as a cluster. The following are the prerequisites for configuring Pooled capacity on NetScaler instances in cluster mode:

Instances are individually running in a Pooled capacity license mode to form the cluster.
All the instances must be running with the same bandwidth.
All the instances checked out the Pooled capacity from the same NetScaler Console.
New instances cannot be added to an existing NetScaler cluster unless their capacity and NetScaler Console configurations are the same as those of the existing instances in the cluster.

Any capacity check-out from the NetScaler cluster assigns the 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 NetScaler 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 process the traffic with the remaining instances’ capacity.

Allocate NetScaler Pooled capacity to a NetScaler cluster

Allocate licenses to each cluster node separately. Because the commands to propagate and synchronize licenses across the cluster nodes are disabled.

Repeat the following procedure on each cluster node:

In a web browser, type the NetScaler IP address (NSIP). 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 NetScaler Console, select the Register with NetScaler Console for manageability checkbox and enter the NetScaler Console 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 NetScaler 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.

Allocate NetScaler Pooled capacity to a NetScaler cluster using the CLI

Allocate licenses to each cluster node separately. Because the commands to propagate and synchronize licenses across the cluster nodes are disabled.

Repeat the following procedure on each cluster node:

In an SSH client, enter the NetScaler IP address (NSIP), and log in by using administrator credentials.

To add a licensing server, enter the following command:

add ns licenseserver (<licenseServerIP> | <serverName>) [-port <port number >]
<!--NeedCopy-->

add-license-server-cli-1

To show the available licenses on the licensing server, enter the following command:
```
sh licenseserverpool

```
To assign a license to the NetScaler VPX appliance, enter the following command:
```
set capacity –platform V\[S/E/P\]\[Bandwidth\]

```
