After you have installed and configured the Citrix ADC VPX instance on VMware ESX, you can use the VMware vSphere web client to configure the virtual appliance to use single root I/O v virtualization (SR-IOV) network interfaces.

限制

A Citrix ADC VPX configured with SR-IOV network interface has the following limitations:

The following features are not supported on SR-IOV interfaces using the Intel 82599 10G NIC on ESX VPX:
- L2 mode switching
- Static Link Aggregation and LACP
- Clustering
- Admin partitioning [Shared VLAN mode]
- High Availability [Active - Active mode]
- Jumbo frames
- IPv6
The following features are not supported on the SR-IOV interface with an Intel 82599 10G NIC on KVM VPX:
- Static Link Aggregation and LACP
- L2 mode switching
- Clustering
- Admin partitioning [Shared VLAN mode]
- High Availability [Active – Active mode]
- Jumbo frames
- IPv6
- VLAN configuration on Hypervisor for SR-IOV VF interface throughip linkcommand is not supported

Prerequisite

Make sure that you:

Add the Intel 82599 NIC (NIC) to the ESX Host. IXGBE driver version 3.7.13.7.14iov is recommended.
Enable SR-IOV on the host physical adapter, as follows:
1. In the vSphere Web Client, navigate to the Host.
2. On theManage > Networkingtab, selectPhysical adapters. The SR-IOV Status field shows whether a physical adapter supports SR-IOV.
3. Select the physical adapter, and then click the pencil icon to open theEdit Settingsdialog box.
4. Under SR-IOV, selectEnabledfrom theStatusdrop-down list.
5. In theNumber of virtual functionsfield, enter the number of virtual functions that you want to configure for the adapter.
6. ClickOK.
7. Restart the host.
Create a Distributed Virtual Switch (DVS) andPortgroups. For instructions, see the VMware Documentation.

Note

Citrix has qualified the SR-IOV configuration on DVS andPortgroupsonly.

To configure Citrix ADC VPX instances to use SR-IOV network interface by using VMware vSphere Web Client:

In the vSphere Web Client, selectHosts and Clusters.
Upgrade the Compatibility setting of the Citrix ADC VPX instance to ESX 5.5 or later, as follows:
a. Power off the Citrix ADC VPX instance.
b. Right-click the Citrix ADC VPX instance and selectCompatibility > Upgrade VM Compatibility.
c. In the配置ure VM Compatibilitydialog box, selectESXi 5.5 and laterfrom theCompatible withdrop-down list and clickOK.
Right-click on the Citrix ADC VPX instance and clickEdit Settings.
In the - Edit Settingsdialog box, click theCPUsection.
In theCPUsection, update the following settings:
- Number of CPUs
- Number of Sockets
- Reservations
- Limit
- Shares
Set the values as follows:
a. In theCPUdrop-down list, select the number of CPUs to assign to the virtual appliance.
b. In theCores per Socketdrop-down list, select the number of sockets.
c. (Optional) In theCPU Hot Plugfield, select or clear theEnable CPU Hot Addcheck box.
Note:Citrix recommends accepting the default (disabled).
d. In theReservationdrop-down list, select the number that is shown as the maximum value.
e. In theLimitdrop-down list, select the number that is shown as the maximum value.
f. In theSharesdrop-down lists, selectCustomand the number that is shown as the maximum value.
In the内存section, update the following settings:
- Size of RAM
- Reservations
- Limit
- Shares
Set the values as follows:
a. In theRAMdrop-down list, select the size of the RAM. It must be the number of vCPUs x 2 GB. For example, if the number of vCPU is 4 then RAM = 4 x 2 GB = 8 GB.
Note:For Advanced or Premium edition of the Citrix ADC VPX appliance, make sure that you allocate 4 GB of RAM to each vCPU. For example, if the number of vCPU is 4 then RAM = 4 x 4 GB = 16 GB.
b. In theReservationdrop-down list, enter the value for the memory reservation, and select theReserve all guest memory (All locked)check box. The memory reservation must be number of vCPUs x 2 GB. For example, if the number of vCPUs is 4, the memory reservation must be 4 x 2 GB = 8 GB.
Note:For Advanced or Premium edition of the Citrix ADC VPX appliance, make sure that you allocate 4 GB of RAM to each vCPU. For example, if the number of vCPU is 4 then RAM = 4 x 4 GB = 16 GB.
c. In theLimitdrop-down list, select the number that is shown as the maximum value.
d. In theSharesdrop-down lists, selectCustom, and select the number that is shown as the maximum value.
Add an SR-IOV network interface. From theNew devicedrop-down list, selectNetwork并点击Add.
In theNew Networksection. From the drop-down list, select thePortgroupthat you created, and do the following:
a. In theAdapter Typedrop-down list, selectSR-IOV passthrough.
b. In thePhysical functiondrop-down list, select the physical adapter mapped with thePortgroup.
c. In theGuest OS MTU Changedrop-down list, selectDisallow.
In the - Edit Settingsdialog box, click theVM Optionstab.
On theVM Optionstab, select theAdvancedsection. From theLatency Sensitivitydrop-down list, selectHigh.
ClickOK.
Power on the Citrix ADC VPX instance.
Once the Citrix ADC VPX instance powers on, you can use the following command to verify the configuration:

show interface summary

The output must show all the interfaces that you configured:
