List Cloud Servers and Cloud Server Information

In addition to viewing CPU, RAM, and disk space configuration information for available cloud servers, you can also view disk, I/O, and networking information. Use this information to help you decide which cloud server is right for your needs. You can view the servers through either the command-line nova client or the Cloud Control Panel GUI.

View server information through novaclient

For information about installing the nova client on Windows, Linux, or Mac systems, see  Using python-novaclient with the Rackspace Cloud.

On the command line, run the following command::

$ nova flavor-list

All available server configurations are displayed.

The server list contains the following information:

  • ID – The configuration ID
  • Name – The configuration name, labeled by RAM size and performance type
  • Memory_MB – The amount of RAM that the configuration has
  • Disk – The size of the disk in GB (for General Purpose Cloud Servers, the size of the system disk)
  • Ephemeral – The size of the data disk
  • Swap – The size of the swap space
  • VCPUs – The number of virtual CPUs associated with the configuration
  • RXTX_Factor – The amount of bandwidth, in Mbps, allocated to the PublicNet ports, ServiceNet ports, and isolated networks (Cloud Networks) attached to a server
  • Is_Public – Not used

You will see one of the following possible result sets, depending on whether the region you selected supports General Purpose Cloud Servers:

Server list for General Purpose and Compute, I/O, or Memory servers


Server list for only General Purpose servers

Copy the ID of the configuration that you want to use from the ID field. You need it to create your server. To create a cloud server with nova client, see the Next Generation Cloud Servers Developer Guide.


View server information through the Cloud Control Panel

You can view all the available information for your cloud server through the Cloud Control Panel GUI. On a single page, you choose what type of server to create (Windows or Linux) and the server configuration that best meets your needs. Each server option has a unique configuration of RAM, CPU, and disk space.

  1. Log in to the Cloud Control Panel.
  2. On the Cloud Servers page, click Create Server.
  3. Enter a name and choose a location for your server.
  4. Select the operating system for your server.
  5. Select the configuration (flavor) by choosing the class of server: General Purpose, Compute, I/O, or Memory.
  6. Use the slider bar to select the configuration of your server.
    The following information is listed for each configuration:
    • CPU - The number of vCPUs
    • RAM - The amount of RAM
    • Boot Source - Allows you to boot a server from a remotely attached volume, which moves the system disk from local to remote 
    • System Disk - The size of the system disk (either 20 GB or 40 GB)
    • Network - The network throughput
    • Disk I/O - A comparison of the I/O speed of this configuration with the I/O speed of other configurations — Good, Better, or Best

A description of the selected configuration can help you decide if the configuration is right for you.

When you are satisfied with your server information and configuration, click Create Server.
