Configure pooled capacity

July 16, 2019
Contributed by:  C M

In Citrix Application Delivery Management (ADM), you can allocate licenses from the license pool to Citrix ADC instances on demand. You can upload the pooled capacity license files to the License Server.

You can also check out the licenses from Citrix ADC (VPX, MPX, and BLX) instances based on the minimum and maximum capacity of an instance.

Configure ADM as License Server

Note

Configure a License Server to pool and allocate the licenses to the pooled-capacity enabled instances. Otherwise, check out licenses from the pooled capacity enabled ADC instance.

You can configure the ADM as a License Server for the pooled capacity. With this configuration, you can allocate licenses to a Citrix ADC instance in two ways:

  • An ADC instance sends a check-out request to Citrix ADM to obtain its bandwidth and instance licenses.

  • The licenses are allocated to the ADC instance through ADM.

Note

You can view the pooled capacity in Citrix ADM only if the pooled licenses are added to the ADM.

The following are the operating modes of the instances that are using the pooled capacity:

  • Optimum: Instance is running with proper license capacity.

  • Capacity mismatch: Instance is running with a capacity less than user configured.

  • Grace: Instance is running on grace license.

  • Grace & Mismatch: Instance is running on grace but with a capacity less than user configured.

  • Not available: Instance is not registered with ADM for management, or NITRO communication from ADM to the instances is not working.

  • Not allocated: License is not allocated in the instance.

Install license files on ADM

  1. In Citrix ADM, navigate to Networks > Licenses.

  2. In the License Files section, select Add License File and select one of the following options:

    • Upload license files from a local computer. If a license file is already present on your local computer, you can upload it to ADM.

    • Use license access code. Specify the license access code for the license that you have purchased from Citrix and select Get Licenses. Then select Finish.

    Note

    At any time, you can add more licenses to ADM from the License Settings.

Allocate pooled capacity licenses from ADM

Prerequisite: Before you can manage your instance’s pool licenses through ADM, you must register the instance with ADM.

  1. Log in to Citrix ADC GUI.

  2. Navigate to System > Licenses > Manage Licenses.

  3. Click Add New License.

  4. Select Use remote licensing and select the remote licensing mode from the list.

  5. In Server Name/IP address, Specify the host name or IP address of Citrix ADM which you have configured as a License Server.

  6. Check the Register with Citrix ADM check box and click Continue.

    Note

    If you have not registered the instance with ADM, you can check out licenses from ADM, but you cannot allocate the from ADM to the pooled capacity enabled instance.

    Note

    In the user name and password fields on the above screen, enter your ADM credentials.

  7. Select the license edition and specify the required bandwidth.

  8. Click Get Licenses.

After the instance is registered with the License Server, allocate the licenses from Citrix ADM as follows:

  1. Log in to Citrix ADM.

  2. Navigate to Networks > Licenses > Bandwidth Licenses > Pooled Capacity.

  3. Click on the license pool that you want to manage.

  4. Select an ADC instance from the list of available instances by clicking on the > button.

    The License status column displays corresponding license allocation status messages.

  5. If you want to change or release a license allocation, click Change allocation or Release allocation.

  6. A pop-up window with the available licenses in the License Server appears.

  7. You can choose the bandwidth or instance allocation to the instance by setting the Allocate list options. After making your selections, click Allocate.

  8. You can also change the allocated license edition from the list options in the Change License Allocation window.

Configure pooled capacity on ADC MPX-Z instances

MPX-Z is the pooled-capacity enabled ADC MPX appliance. MPX-Z supports bandwidth pooling for Premium, Advanced, or Standard edition licenses.

MPX-Z requires platform licenses before it can connect to the License Server. You can install the MPX-Z platform license by either uploading the license file from a local computer or using the instance’s hardware serial number, or the License Access Code from System > Licenses section of the instance’s GUI. If you remove the MPX-Z platform license, the pooled-capacity feature is disabled and all the checked-out licenses are checked in to the License Server.

You can dynamically modify the bandwidth of a MPX-Z instance without a restart. A restart is required only if you want to change the license edition.

Note

When you restart the instance, it automatically checks out the pooled licenses required for its configured capacity.

Configure pooled capacity on ADC VPX instances

A pooled-capacity enabled ADC VPX instance can check-out licenses from a bandwidth pool (Premium/Advanced/Standard editions). You can use the ADC GUI to check-out licenses from the License Server.

You can dynamically modify the bandwidth of a VPX instance without a restart. A restart is required only if you want to change the license edition.

Note

When you restart the instance, it will automatically check-out the pooled licenses required for its configured capacity.

Allocate pool licenses to ADC MPX-Z or ADC VPX instances from Citrix ADC

To allocate your licenses:

  1. Navigate to System > Licenses > Manage Licenses, click Add New License and select Use Pooled Licensing.

  2. Enter the details of the License Server in the Server Name/IP Address field.

  3. If you want to manage your instance’s pool licenses through ADM, select the Register with Citrix ADM check box and enter the ADM credentials.

  4. Select the license edition and the required bandwidth, click Get Licenses.

  5. You can change or release the license allocation by selecting Change allocation or Release allocation.

  6. If you click Change allocation, a pop-up window shows the licenses available on the License Server.

    Note

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

  7. You can allocate bandwidth or instances to the instance from the Allocate list. Then click Get Licenses.

  8. You can choose the license edition and the bandwidth required from the drop-down lists in the pop-up window.

    Note

    Bandwidth allocation should be a multiple of the minimum bandwidth unit.
