VM template settings

A VM template describes the resource allocation that you want to provide for a type of VMs. When Turbonomic deploys the associated VM to your environment or in a plan, it uses these values to determine the size of the VM. Turbonomic uses the Size settings to calculate the best placement for a VM of this type.

A VM template can optionally include an image description. When Turbonomic uses the template to deploy a VM to your environment, it uses the image to access the actual bits that install as the VM instance.

Note:

Turbonomic generates a special template called headroomVM, which it uses to calculate cluster headroom. The Template Catalog shows the template as editable, but you should not edit it because Turbonomic will overwrite your changes the next time it generates the template.

VM size

  • CPU

    The virtual CPUs assigned to the VM. Specify the number of Cores and the VCPU clock speed – Turbonomic multiplies these values to calculate the host CPU resources it will allocate when placing the VM.

    The Utilization value sets the percentage of allocated CPU that the placed VM will consume. To ensure the host has left over resources for infrastructure tasks, you should assign less than 100%.

  • Memory

    The amount of memory to allocate for the VM, in MB.

    The Utilization value sets the percentage of allocated memory that the placed VM will consume. To ensure the host has left over resources for infrastructure tasks, you should assign less than 100%.

    Note that you should never allocate less memory than is required for the VM's guest OS.

  • Storage

    The storage resources to allocate for this VM.

    • disk/rdm – If you choose rdm, then the VM can use VMware Raw Device Mapping for its storage.

    • IOPS – The capacity for IO operations you give the VM for this datastore.

    • Size – The amount of storage capacity, in GB.

    The Utilization value sets the percentage of allocated memory that the placed VM will consume. To ensure the storage has left over resources for infrastructure tasks, you should assign less than 100%.

    Note that you can allocate multiple datastores to the VM.

  • Network

    The amount of the host’s network throughput to assign to the VM, in Mb/s.

  • IO

    The amount of throughput on the host’s IO bus to assign to the VM, in Mb/s
