Configure a Citrix ADC VPX instance to use Azure accelerated networking 编辑

Accelerated networking enables the single root I/O virtualization (SR-IOV) virtual function (VF) NIC to a virtual machine, which improves the networking performance. You can use this feature with heavy workloads that need to send or receive data at higher throughput with reliable streaming and lower CPU utilization. When a NIC is enabled with accelerated networking, Azure bundles the NIC’s existing para virtualized (PV) interface with an SR-IOV VF interface. The support of SR-IOV VF interface enables and enhances the throughput of the Citrix ADC VPX instance.

Accelerated networking provides the following benefits:

• Lower latency
• Higher packets per second (pps) performance
• Enhanced throughput
• Reduced jitter
• Decreased CPU utilization

Note

Azure accelerated networking is supported on Citrix ADC VPX instances from release 13.0 build 76.29 onwards.

Prerequisites

• Ensure that your VM size matches the requirements for Azure accelerated networking.
• Stop VMs (individual or in an availability set) before enabling accelerated networking on any NIC.

Limitations

Accelerated networking can be enabled only on some instance types. For more information, see Supported instance types.

NICs supported for accelerated networking

Azure provides Mellanox ConnectX3 and ConnectX4 NICs in the SR-IOV mode for accelerated networking.

When accelerated networking is enabled on a Citrix ADC VPX interface, Azure bundles either ConnectX3 or ConnectX4 interface with the existing PV interface of a Citrix ADC VPX appliance.

For more information about enabling accelerated networking before attaching an interface to a VM, see Create a network interface with accelerated networking.

For more information about enabling accelerated networking on an existing interface on a VM, see Enable existing interfaces on a VM.

How to enable accelerated networking on a Citrix ADC VPX instance using the Azure console

You can enable accelerated networking on a specific interface using the Azure console or the Azure PowerShell.

Do the following steps to enable accelerated networking by using Azure availability sets or availability zones.

1. Log in to Azure portal, and navigate to Azure Marketplace.

   

2. From the Azure Marketplace, search Citrix ADC.

   

3. Select a non-FIPS Citrix ADC plan along with license, and click Create.

   

   The Create Citrix ADC page appears.

4. In the Basics tab, create a Resource Group. Under the Parameters tab, enter details for the Region, Admin user name, Admin Password, license type (VM SKU), and other fields.

   

5. Click Next : VM Configurations >.

   On the VM Configurations page, perform the following:

   1. Configure public IP domain name suffix.
   2. Enable or disable Azure Monitoring Metrics.
   3. Enable or disable Backend Autoscale.

   

6. Click Next: Network and Additional settings >.

   On the Network and Additional Settings page, create a Boot diagnostics account and configure the network settings.

   Under the Accelerated Networking section, you have the option to enable or disable the accelerated networking separately for the Management interface, Client interface, and Server interface.

   

7. Click Next: Review + create >.

   After the validation is successful, review the basic settings, VM configurations, network and additional settings, and click Create. It might take some time for the Azure Resource Group to be created with the required configurations.

   

8. After the deployment is complete, select the Resource Group to see the configuration details.

   

9. To verify the Accelerated Networking configurations, select Virtual machine > Networking. The Accelerated Networking status is displayed as Enabled or Disabled for each NIC.

   

Enable accelerated networking using Azure PowerShell

If you need to enable accelerated networking after the VM creation, you can do so using Azure PowerShell.

Note:

Ensure to stop the VM before you enable Accelerated Networking using Azure PowerShell.

Perform the following steps to enable accelerated networking by using Azure PowerShell.

1. Navigate to Azure portal, click the PowerShell icon on the right-hand top corner.

   Note:

   If you are in the Bash mode, change to the PowerShell mode.

   

2. At the command prompt, run the following command:

   az network nic update --name <nic-name> --accelerated-networking [true | false] --resource-group <resourcegroup-name>
