17.2 Modifying a Workload Template

You can modify a workload template to change the general information (name, license costs, and description) and the VM resource settings. Modifications do not affect currently requested or deployed business services.

  1. In the Cloud Manager console, click Catalog, then click the Workload Templates tab.

  2. Select the workload template you want to modify, then click Edit.

  3. In the General section, modify the following information for the workload template:

    Name: Specify a name for the workload template. The name should be different than any other workload template name.

    License Costs: Specify the license costs associated with the template’s software. This cost is per month.

    Zone: Displays the zone you selected for the workload template. You cannot change this setting.

    Creation Date: Displays the date the template was created. You cannot change this setting.

    Description: Provide any additional information to identify the workload template.

  4. In the Virtual Machines Settings section:

    1. Select a different VM template if desired.

      If the workload template is associated with a currently deployed business service, you cannot change the VM template. In this case, the VM Template field is read-only.

    2. Customize the resource settings associated with the VM template.

      You cannot change the VM template. However, you can change any of the values to increase or decrease the resources for workloads created from the VM template.

      Number of CPUs: Select the number of CPUs for a workload. Currently, some hypervisor technologies do not support more than 8 CPUs per workload, so the maximum number allowed is 8.

      Each host group includes a vCPUs per Host setting that defines the number of available vCPUs per host in the group. You should makes sure the number you select here does not exceed the per host number for any host group that might service the workload. Otherwise, the workload will not be able to run.

      Memory: Select the megabytes (MB) of RAM to allocate to a workload.

      Number of NICs: Select the number of network interface cards (NICs) to allocate to the workload.

      Disks Summary: Displays the size of the mandatory workload disks and the number of optional workload disks defined in the template, Mandatory workload disks are always created. They are inherited from the VM template or manually defined (on the Disks tab). Optional workload disks are available to the user but are created only if the user specifies sizes for the disks.

      You add, edit, and remove disks on the Disks page (see Step 5 below).

    3. By default, each resource setting is locked, which means that a business service requestor cannot change it. If you want to enable a requestor to change a setting when creating a workload from the template, deselect the check box.

  5. If you want to change the additional disks, click the Disks tab, then do any of the following:

    • Add a disk: You can include up to 10 disks. Click Add to add a disk to the list. Make sure the disk is selected, then specify a size in the Size field (below the list) to make the disk mandatory. Or, leave the size set to 0 to make the disk optional. The maximum size per disk is 10240 GB (1 TB).

      If you specify the size when adding a disk, the disk becomes mandatory. Users cannot remove or change a mandatory disk. If you add a disk with size set to 0, the disk becomes optional. When creating a workload, users can add optional disks and specify their sizes (1 to 1024 GB).

      In the Cost field, select the check box if you want to charge money for the disk. If you don’t enable the Cost option, the disk becomes a free disk and is not included when calculating the cost of a business service.

    • Remove a disk: Select the disk in the list, then click Remove. You cannot remove disks that have the icon in front of them. These are non-removable disks inherited from the VM template.

    • Change a disk size or cost calculation: Select the disk in the list, then modify the Size and Cost fields.

  6. Click OK.
