Beginning with the NSX-T Data Center 3.0 release, support for the Intel QuickAssist Technology (QAT) is provided on bare metal servers. Intel QAT provides the hardware acceleration for various cryptography operations.
The QAT feature is enabled by default if the NSX Edge is deployed on a bare metal server with an Intel QuickAssist PCIe card that is based on the installed C62x chipset (Intel QuickAssist Adapter 8960 or 8970). The single root I/O virtualization (SR-IOV) interface must be enabled in the BIOS firmware.
To check the status of the QAT feature, enter the following command on the
NSX Edge bare metal server CLI.
get dataplane qat
The possible responses you might receive are listed in the following table.
| Status of QAT Feature | Definition |
|---|---|
| QAT present, enabled, running | The QAT feature is enabled and running. |
| QAT present, enabled, not running | The QAT feature has been enabled, but the dataplane service must be restarted for the status change to take effect. |
| QAT present, disabled, not running | The QAT feature is disabled. |
| QAT present, disabled, running | The QAT feature has been disabled, but the dataplane service must be restarted for the status change to take effect. |
| QAT not present | The bare metal server on which you ran the CLI command does not have a QAT device installed. |
| QAT not supported in VM | You ran the CLI command on a VM edge. |
To disable or enable the use of an installed QAT device, use the following CLI commands. The expected responses are also shown.
set dataplane qat disabled QAT disabled. Please restart service dataplane to take effect.
set dataplane qat enabled QAT enabled. Please restart service dataplane to take effect.
Important: You must enter the
restart service dataplane command at the CLI prompt for the QAT feature status change to take effect.
