Create Bare Metal Cloud Host

In the UCloud Global console, select the Bare Metal Cloud Host product and click on [Create Host] to enter the creation page.

On the creation page, select the region, availability zone, machine type, image, etc., and set the network and management information. Click on [Buy Now], and after payment, you will be automatically redirected to the host management page. Wait for the host to enter running status to start using it.

Tips:

• If your account does not have permissions for certain regions (not visible in the console), please contact your account manager or provide feedback to SPT.
• Bare Metal Cloud Host currently only supports daily, monthly, and yearly payments; hourly payments are not supported.
• If resources appear sold out in the console, please contact your account manager or provide feedback to SPT for the exact resource launch time.
• If the console does not offer configurations that meet your business needs, feel free to provide feedback through any channel, and the product team will evaluate it accordingly.

Bare Metal Cloud Host Management

Every bare metal cloud host can perform basic operations such as start, shutdown, restart, reinstall, and delete, with support for batch processing.

Tips:

• Reinstalling the system does not incur additional costs.
• When deleting a host, the cost for the remaining time will be automatically refunded.

Emergency Login

The emergency login function differs from the VNC login provided by cloud hosts. Its purpose is to allow you to log into the machine at the first opportunity to troubleshoot in case of a host malfunction. Of course, you can also use this function to replace SSH or jump server login methods.

Tips:

• Some bare metal cloud hosts do not currently support IPMI features. If there is a network disconnection or downtime, please urgently contact SPT. All hosts will support IPMI features by the end of April 2020.

Configure Java Environment

Please visit the official Java website and follow the instructions  to install the latest Java runtime environment.

Configure Java Security List

Take Windows as an example. Open Control Panel -> Select Java -> Security tab -> Edit Site List.

Based on the availability zone of your bare metal cloud host, configure the following addresses as exceptions:

Console Login

In the console menu, select: Emergency Login. At this point, a jnlp file will be downloaded. If you have configured the Java environment, you can open this file to log in to the bare metal cloud host normally.

Please ignore any related security warnings.

For a better user experience, it is recommended to use Firefox or Chrome browsers for login operations.

Monitoring

Bare Metal Cloud Hosts support monitoring functions, with monitoring indicators consistent with cloud hosts.

However, installing a monitoring agent is necessary (UCloud Global Monitor Agent). Refer to the Monitoring Agent Instructions for detailed steps.

Note: Windows bare metal cloud hosts do not currently support this feature.

GPU Bare Metal Cloud Host Temperature Monitoring Installation

It is recommended to install UMA on your GPU bare metal cloud host for temperature monitoring.

1. Install NVIDIA Driver

2. Visit the NVIDIA website to get the download address 

   • Select specific model for Product Family
   • Select CUDA version supported by the driver for CUDA ToolKit, without selection is the default version

3. After selection, click Search → Download, and copy the link address (Example for A100 in the images above)

4. Enter the host and execute the command to download the driver (wget followed by the copied link address): wget {copied link address from the previous step}

   • Check if gcc and make software libraries are installed, and install gcc and make

   ## Use 'which make' to check if make is installed, use command '# sudo apt-get install make' to install
   ## Use 'gcc --version' to check if gcc is installed, use command '# sudo apt-get install gcc' to install

5. Start installation: Execute sh NVIDIA-xxxxxxx.run to start the driver installation. Note: Add sudo before the command if there are permission issues.

6. Verify the NVIDIA driver: Execute nvidia-smi

7. Install UMA

Refer to the Monitoring Agent Instructions for details.

Alarm settings can be added under Monitoring -> Monitoring Templates, with the recommendation to set the GPU temperature alert threshold to 90°C.
