VPX instance on Microsoft Hyper-V

Hyper-V version	SysID	VPX models
2016, 2019	450020	VPX 10, VPX 25, VPX 200, VPX 1000, VPX 3000

VPX instance on Nutanix AHV

NetScaler VPX is supported on Nutanix AHV through the Citrix Ready partnership. Citrix Ready is a technology partner program that helps software and hardware vendors develop and integrate their products with NetScaler technology for digital workspace, networking, and analytics.

For more information on a step-by-step method to deploy a NetScaler VPX instance on Nutanix AHV, see Deploying a NetScaler VPX on Nutanix AHV.

Third-party support:

If you experience any issues with a particular third-party (Nutanix AHV) integration on a NetScaler environment, open a support incident directly with the third-party partner (Nutanix).

If the partner determines that the issue appears to be with NetScaler, the partner can approach NetScaler support for further assistance. A dedicated technical resource from partners works with the NetScaler support team until the issue is resolved.

For more information, see the Citrix Ready Partner Program FAQs.

VPX instance on generic KVM

Generic KVM version	SysID	VPX models
RHEL 7.4, RHEL 7.5 (from NetScaler version 12.1 50.x onwards), RHEL 7.6	450070	VPX 10, VPX 25, VPX 200, VPX 1000, VPX 3000, VPX 5000, VPX 8000, VPX 10G, VPX 15G. VPX 25G, VPX 40G, VPX 100G
RHEL 8.0, Ubuntu 16.04, Ubuntu 18.04, RHV 4.2	450070

Points to note:

Consider the following points while using KVM hypervisors.

The VPX instance is qualified for hypervisor release versions mentioned in table 1–4, and not for patch releases within a version. However, the VPX instance is expected to work seamlessly with patch releases of a supported version. If it does not, log a support case for troubleshooting and debugging.
Before using RHEL 7.6, complete the following steps on the KVM host:
1. Edit /etc/default/grub and append "kvm_intel.preemption_timer=0" to GRUB_CMDLINE_LINUX variable.
2. Regenerate grub.cfg with the command "# grub2-mkconfig -o /boot/grub2/grub.cfg".
3. Restart the host machine.
Before using Ubuntu 18.04, complete the following steps on the KVM host:
1. Edit /etc/default/grub and append "kvm_intel.preemption_timer=0" to GRUB_CMDLINE_LINUX variable.
2. Regenerate grub.cfg with the command "# grub-mkconfig -o /boot/grub/grub.cfg “.
3. Restart the host machine.

VPX instance on AWS

AWS version	SysID	VPX models
N/A	450040	VPX 10, VPX 200, VPX 1000, VPX 3000, VPX 5000, VPX BYOL, VPX 8000, VPX 10G, VPX 15G, and VPX 25G are available only with BYOL with EC2 instance types (C5, M5, and C5n)

Note:

The VPX 25G offering doesn’t give the 25G throughput in AWS but can give a higher SSL transactions rate compared to the VPX 15G offering.

VPX instance on Azure

Azure version	SysID	VPX models
N/A	450020	VPX 10, VPX 200, VPX 1000, VPX 3000, VPX 5000, VPX BYOL

VPX features supported on public clouds

Multi-PE Support	Yes	Yes	Yes
Clustering Support	No	No	No

Hot-plug	Yes	No	No

The superscript numbers (1, 2, 3) used in the preceding tables refers to the following points with respective numbering:

Clustering support is available on SRIOV for client-facing and server-facing interfaces, and not for the backplane.
Interface DOWN events are not recorded in NetScaler VPX instances.
For Static LA, traffic might still be sent on the interface whose physical status is DOWN.

The following points apply to the respective features captured in the two preceding tables:

For LACP, the peer device knows the interface DOWN event based on the LACP timeout mechanism.
- Short timeout: 3 seconds
- Long timeout: 90 seconds
For LACP, do not share interfaces across VMs.
For Dynamic routing, convergence time depends on the Routing Protocol since link events aren’t detected.
Monitored static Route functionality fails if you do not bind monitors to static routes because the Route state depends on the VLAN status. The VLAN status depends on the link status.
Partial failure detection does not happen in high availability if there’s link failure. High availability-split brain condition might happen if there’s link failure.
- When any link event (disable/enable, reset) is generated from a VPX instance, the physical status of the link does not change. For static LA, any traffic initiated by the peer gets dropped on the instance.
- For the VLAN tagging feature to work, do the following:
  
  On the VMware ESX, set the port group’s VLAN ID to 1–4095 on the vSwitch of the VMware ESX server. For more information about setting a VLAN ID on the vSwitch of the VMware ESX server, see VMware ESX Server 3 802.1Q VLAN Solutions.
Hot-plug is not supported on VPX instances with ENA interfaces, and the behavior of the instances can be unpredictable if hot-plugging is attempted. Hot adding is supported only for PV and SRIOV interfaces with NetScaler on AWS.
Hot removing either through the AWS Web console or AWS CLI interface is not supported with the PV, SRIOV, and ENA interfaces for NetScaler. The behavior of the instances can be unpredictable if hot-removal is attempted.
