Get started with Xtreme1

For Xtreme1 to operate, the cloud server must be accessible from the Internet. To achieve this, when creating a server, you must create a private subnet and attach a public floating IP address.

1. Create a public floating IP address.

2. Create a cloud server with Xtreme1.

3. Create an account.

4. Launch Xtreme1.

1. Create a public floating IP address

Create a public floating IP address to make the cloud server with Xtreme1 accessible from the internet.

Use the Create a public floating IP address section of the Public Floating IP addresses guide.

2. Create a cloud server with Xtreme1

1. In the Control panel, on the top menu, click Products and select Cloud Servers.

2. Click Create server.

3. Fill in the blocks:

   • Name and placement;
   • Source;
   • Configuration;
   • Volumes;
   • Internet;
   • Private network;
   • Security;
   • Access;
   • Additional settings.

4. Check the cloud server price.

5. Click Create.

Name and placement

1. Enter a server name. It will be set as the hostname in the operating system.

2. Select a location where the server will be created. The available server configurations and resource costs depend on the location. You cannot change the location after the server has been created.

Source

1. Open the Applications tab.

2. Select Xtreme1 VM.

3. Optional: if you need a different current or archived application version, select the required version in the Version field.

Configuration

Select a configuration from 2 vCPU, RAM starting from 4 GB and a boot disk size starting from 20 GB. For all lines, except Shared and Dedicated, two types of server configurations are available:

• fixed configurations — configurations of lines with different technical specifications where the resource ratio is fixed;
• custom configurations — configurations in which you can specify any resource ratio.

Configurations use different processors depending on the line and pool segment. You can customize the selected configuration. After the server is created, you will be able to change the configuration.

Fixed configuration

1. Open the tab with a line.

2. Click Fixed.

3. Optional: you can customize the configuration if you are creating a server in a multi-AZ pool ru-6 segment or ru-3b, ru-7a, and ru-7b pool segments:

   3.1. Expand the block with the configuration settings description.

   3.2. Optional: select a processor manufacturer. Choosing a manufacturer is not available in all pools.

   3.3. Optional: if you do not want physical processor cores to be pinned to the vCPUs of the cloud server, uncheck the Dedicated cores checkbox. For more information, see the Dedicated cores instruction.

   3.4. Optional: if you want to disable Hyper-Threading for a server with dedicated cores, uncheck the Hyper-Threading (SMT) checkbox.

   3.5. Optional: if you are creating a cloud server with dedicated cores and want to place a multiprocessor server on a single NUMA node, check the Mandatory placement on a single NUMA node checkbox. You can place a server with 4 vCPUs or more on one NUMA node. If the cloud server resources cannot be placed on one node, it will not be created. For more information, see the Placement on a single NUMA node section of the Dedicated Cores instruction.

4. Select a configuration.

5. If both local and network volumes are available in the selected configuration, select the volume to be used as the boot disk:

   • local disk — check the Local SSD NVMe disk checkbox. A server with a local disk can only be created from images and applications;
   • network volume — do not check the Local SSD NVMe disk checkbox.

   The amount of RAM allocated to the server may be less than specified in the configuration — the operating system kernel reserves part of the memory depending on the kernel version and distribution. You can check the allocated volume on the server using the sudo dmesg | grep Memory command.

Custom configuration

1. Open the tab with a line.

2. Click Custom.

3. Optional: you can customize the configuration if you are creating a server in a multi-AZ pool ru-6 segment or ru-3b, ru-7a, and ru-7b pool segments:

   3.1. Expand the block with the configuration settings description.

   3.2. Optional: select a processor manufacturer. Choosing a manufacturer is not available in all pools.

   3.3. Optional: if you do not want physical processor cores to be pinned to the vCPUs of the cloud server, uncheck the Dedicated cores checkbox. For more information, see the Dedicated Cores instruction.

   3.4. Optional: if you want to disable Hyper-Threading for a cloud server with dedicated cores, uncheck the Hyper-Threading (SMT) checkbox.

   3.5. Optional: if you are creating a cloud server with dedicated cores and want to place a multiprocessor server on a single NUMA node, check the Mandatory placement on a single NUMA node checkbox. You can place a cloud server with 4 vCPUs or more on one NUMA node. If the cloud server resources cannot be placed on one node, it will not be created. For more information, see the Placement on a single NUMA node section of the Dedicated Cores instruction.

4. Specify the number of vCPUs.

5. Specify the RAM size.

6. If you need to add GPUs to the server, click Add GPU, select the GPU type, and specify the number of GPUs. The selected line will change to the GPU line. If in the Source block you chose an image without GPU optimization and have the Auto-select GPU image toggle enabled, the selected image will automatically change to an image with GPU optimization.

7. If both local and network volumes are available in the selected configuration, select the volume to be used as the boot disk:

   • local disk — check the Local SSD NVMe disk checkbox. A server with a local disk can only be created from images and applications;
   • network volume — do not check the Local SSD NVMe disk checkbox.

   The amount of RAM allocated to the server may be less than specified in the configuration — the operating system kernel reserves part of the memory depending on the kernel version and distribution. You can check the allocated volume on the server using the sudo dmesg | grep Memory command.

Volumes

1. If you did not check the Local SSD NVMe disk checkbox during configuration, the first specified network volume will be used as the server's boot disk. To configure it:

   1.1. Select the network boot disk type.

   1.2. Specify the network boot disk size in GB or TB. Mind the network volume limits on the maximum size.

   1.3. If you selected the Universal v2 or SSD Fast v2 disk type, specify the total number of read and write operations in IOPS. After the disk is created, you can change the IOPS amount — reduce or increase it. The number of IOPS changes is unlimited.

2. Optional: add an additional network volume server :

   2.1. Click Add.

   2.2. Select the network volume type.

   2.3. Specify the size of the network disk in GB or TB. Keep in mind the network volume limits on the maximum size.
