Cloud groups create isolated environments,
such that workloads running in one group are not affected by workloads
running in another group.
Before you begin
You must be assigned System level, Cloud group administration role with permission to Manage cloud resources (Full permission) to
add cloud groups.
About this task
You can use the console, the command line interface, or the REST API to complete this task. For the command line and REST API information, see the Related information section.Important: If there are not enough resources available in the
system to satisfy the requirements of the new cloud group, the operation
will fail.
Procedure
- Access the console pane. Click .
- Click the New icon
in the toolbar
- 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
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 deploying
patterns, making it possible to have more deployments. Note, however, that this does not increase
the amount of available computing power, but only allows it to be 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.
- 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.
