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 available servers through either the command-line nova client or the Cloud Control Panel interface.
For information about installing the nova client on Windows, Linux, or Mac systems, see Using python-novaclient with Rackspace Cloud Servers.
On the command line, run the following command:
All available server configurations are displayed. The list contains the following information:
- ID - The server 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
Copy the ID of the configuration that you want to use from the ID field. You need it to create your server.
For instructions on creating a cloud server through the nova client, see the Cloud Servers API guide.
You can view all the available information for your cloud server through the Cloud Control Panel interface. 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.
Log in to the Cloud Control Panel.
In the top navigation bar, click Select a Product > Rackspace Cloud.
Select Servers > Cloud Servers.
On the Cloud Servers page, click Create Server.
In the Flavor section, view server configuration information by first choosing the class of server--General Purpose, Compute, Memory, I/O, or Standard--and then using the slider bar to select the specific configuration.
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.
- 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. You can also click the Comparison Chart link to see a comparison chart for all the configurations in each class.
