NSX Manager: manual provisioning of Citrix ADC instances

Citrix Application Delivery Management (ADM) integrates with VMware network virtualization platform to automate the deployment, configuration, and management of Citrix ADC services. This integration abstracts away the traditional complexities associated with physical network topology, enabling vSphere/vCenter admins to programmatically deploy Citrix ADC services faster.

This article provides you with a list of tasks that you have to perform on both VMware NSX Manager and on Citrix ADM.

Note

Ensure that VMware NSX for vSphere 6.2 and above is installed and configured, and the edge gateways, DLR, and virtual machines that have to be load balanced are already created.

Prerequisites

  • Install VMware ESXi version 4.1 or later with hardware that meets the minimum requirements.

  • Install VMware Client on a management workstation that meets the minimum system requirements.

  • Install VMware OVF Tool (required for VMware ESXi version 4.1) on a management workstation that meets the minimum system requirements.

  • Install Citrix ADM on any of the supported hypervisors.

    For tasks to install Citrix ADM build 12.1, on any of the supported hypervisors, see Deploying Citrix ADM.

VMware ESXi Hardware Requirements

The following table lists the virtual computing resources that you require on your VMware ESXi server to install a Citrix ADM virtual appliance.

   
Component Requirement
RAM 8 GB
Virtual CPU 8
Storage space 500 GB
Virtual Network Interfaces 1
Throughput 1 Gbps

Note

The memory and hard disk requirements specified above are for deploying Citrix ADM on VMware ESXi server, considering that there are no other virtual machines running on the host. The hardware requirements for VMware ESXi server depends on the number of virtual machines running on it.

Configuring VMware NSX

  • Create a pool of Citrix ADC VPX instances of different capacities, which are added to the different service packages.

For example:

  • Create five Citrix ADC VPX instances of VPX1000 (1 Gbps). These instances are added to the Gold service package.

  • Create five Citrix ADC VPX instances of VPX10 (10 Mbps). These instances are added to the Bronze service package.

  1. In vSphere client, navigate to Networking, and create a port group of type VLAN trunking with range, for example, 101-105 (you can even provide the full range, but create port group of type VLAN for only the required VLANs).

  2. Create a new interface for each Citrix ADC VPX instance, and attach it to the VLAN range trunk port group that was created above.

    localized image

  3. In vSphere client, navigate to Networking, and create a port group of type VLAN.

    For example, If the initial trunked port group was created with range 101-105, create five VLAN port groups one per VLAN, that is a port group with VLAN 101, another with VLAN102, and so on, until VLAN 105.

Adding Citrix ADC VPX Instance in Citrix ADM

Add Citrix ADC VPX instances in Citrix ADM and specify the VLAN range of the trunked group for each device.

  1. In Citrix ADM, navigate to Infrastructure > Instances > Citrix ADC VPX, and click Add.

  2. On the Add Citrix ADC VPX page, specify either the host names of the instances, the IP address of each instance, or a range of IP addresses, and then select an instance profile from the Profile Name list. You can also create a new instance profile by clicking the + icon.

  3. Click OK.

  4. Select the newly added Citrix ADC VPX instance from the list on the Citrix ADC VPX page, and click the down arrow button in Action field. Select Configure Interfaces for Orchestration.

Registering VMware NSX Manager with Citrix ADM

Register VMware NSX manager with Citrix ADM to create a communication channel between them.

  1. In Citrix ADM, navigate to OrchestrationSDN  Orchestration > VMware NSX Manager from the drop-down list, and click Configure NSX Manager Settings.

  2. On Configure NSX Manager Settings page, set the following parameters:

    1. NSX Manager IP Address - IP address of NSX Manager.

    2. NSX Manager Username - Administrative user name of NSX Manager.

    3. Password - Password of the administrative user of NSX Manager.

  3. In Citrix ADM account used by NSX Manager section, set the Citrix ADC Driver Username and Password for the NSX Manager. Citrix ADM authenticates load balancer configuration requests from the NSX Manager by using these logon credentials.

  4. Click OK.

  5. Navigate to Orchestration > System > Deployment Settings. Provide the VLAN range which was configured in trunked port group.

    localized image

  6. Log on to the NSX Manager on vSphere Web Client, and navigate to Service Definitions > Service Managers.

    You can view Citrix Citrix ADM as one of the service managers. This indicates that the registration is successful and a communication channel is established between the NSX manager and Citrix ADM.

Creating a Service Package in Citrix ADM

  1. In Citrix ADM, navigate to  OrchestrationSDN  Orchestration > VMware NSX Manager > Service Packages, and click Add to add a new service package.

  2. On Service Package page, in Basic Settings section, set the following parameters:

    1. Name – type the name of a service package

    2. Isolation Policy – by default, the isolation policy is set to Dedicated

    3. Device Type – by default, the device type is set to Citrix ADC VPX

      Note

      These values are set by default in this version, and you cannot modify them.

    4. Click Continue.

      localized image

  3. In Assign Devices section, select the pre-provisioned VPX for this package, and click Continue.

  4. In Publish Service Package section, click Continue to publish the service package to VMware NSX, and then click Done.

    This procedure configures a service package in the NSX Manager. A service can have multiple devices added to it and multiple edges can use the same service package to offload the Citrix ADC VPX instance to Citrix ADM.

  5. Log on to the NSX Manager on vSphere Web Client, and navigate to Service Definitions > Services.

    You can see that the Citrix ADM service package is registered.
