NVIDIA Licensing Information

This chapter contains the following sections:

NVIDIA GRID License Server Overview

The NVIDIA Tesla P6 GPU combines Tesla and GRID functionality when you enable the licensed GRID features GRID vGPU and GRID Virtual Workstation. You enable these features during OS boot by borrowing a software license that is served over the network from the NVIDIA GRID License Server virtual appliance. The license is returned to the GRID License Server when the OS shuts down.

The NVIDIA Tesla P6 GPU has dual personality. It can work in Compute (Tesla) and GRID mode. Only GRID mode needs a license.

You obtain the licenses that are served by the GRID License Server from the NVIDIA Licensing Portal as downloadable license files, which you install into the GRID License Server via its management interface. See the following figure.

Figure 1. GRID Licensing Architecture


There are three editions of GRID licenses that enable three different classes of GRID features. The GRID software automatically selects the license edition based on the features that you are using. See the following table.

Installing Drivers to Support the NVIDIA GPU Cards

After you install the hardware, you must update to the correct level of server BIOS, activate the BIOS firmware, and then install NVIDIA drivers and other software in this order:

1. Updating the Server BIOS Firmware

Install the latest Cisco server BIOS for your blade server by using Cisco UCS Manager.


Note

You must do this procedure before you update the NVIDIA drivers.


Caution

Do not remove the hardware that contains the endpoint or perform any maintenance on it until the update process completes. If the hardware is removed or otherwise unavailable due to maintenance, the firmware update fails. This failure might corrupt the backup partition. You cannot update the firmware on an endpoint with a corrupted backup partition.

Procedure

Step 1

In the Navigation pane, click Equipment.

Step 2

On the Equipment tab, expand Equipment > Chassis > Chassis Number > Servers.

Step 3
