Adding cloud groups

Cloud groups create isolated environments, such that workloads running in one group are not affected by workloads running in another group.

1. Access the console pane. Click Cloud > Cloud Groups.
2. Click the New icon in the toolbar
3. Define the cloud group.
   Provide the following information about the cloud group:

   Name

   Provide a name for the cloud group. Each cloud group must have a unique name.

   Description

   Provide a detailed description of the cloud group.

   Type

   Each type defines how resources are allocated to a virtual machine during deployment. Select one of the following:

   Dedicated

   CPU cores and memory are dedicated. No overcommit for memory.

   Average

   CPU cores are shared and capped. No overcommit for memory.

   Virtual Manager

   Deprecation: Virtual Manager Cloud Group is deprecated in Version 2.3.4. For more information, see Deprecated functions and replacements.

   This type of cloud group is not used for deployments. The cloud group resources are reserved for use by external applications managed outside of this system. For details about configuring external application access, see Configuring external application access.

   CPU Ratio

   Select a CPU ratio value to define how finely to divide physical CPUs into virtual CPUs within a cloud group and then click Save. Each cloud group can have a different ratio. By increasing this ratio, it is possible to have more virtual CPUs to distribute when you deploy patterns, making it possible to have more deployments. However, this change does not increase the amount of available computing power, but allows it to be only distributed to deployments in finer increments.

   This option is only available when Type is set to Average.

   Important: On already deployed virtual machines in a cloud group, modify the CPU Ratio value when the deployed virtual machines are in the cloud group and when the system is in maintenance mode. If the system is in non-maintenance mode, the value is read-only. If you modify the value without the maintenance mode, the following error message is displayed:

   CWZIP3008E The rack must be in maintenance mode.

   In a cloud group with no deployed virtual machines, modify the CPU Ratio value whether the system is in maintenance mode or in non-maintenance mode.

   Deployment type

   Select one of the following:

   Multi cloud

   Connects the management traffic of a virtual machine to an external VLAN, allowing the traffic to be subject to external routing and firewalls when that traffic crosses VLANs. It also allows virtual machines deployed to this cloud group to communicate with virtual machines in other cloud groups or other systems for the purpose of management and monitoring.

   Single cloud

   Restricts virtual machine management traffic to a private VLAN reserved only for this cloud group and contained entirely within this system

   After the cloud group is created, the Deployment type value becomes permanent.

   Management VLAN ID

   Specify an integer value between 1 and 4094. Ensure that the specified integer value is one that is not already in use in your data center. The VLANs that are already in use are listed in this field. This value is not present if you selected the Multi cloud option on the Deployment type setting.

4. Click OK.
   The name of the new cloud group is shown in the left pane of the Cloud Groups pane. The right pane contains the configuration settings for the cloud group.
