• Disk Size. Appears only if Custom Disk Size is not selected. Define the volume size in GB.
• QoS Type. Three options: Empty (no Quality of Service), hypervisor (rate limiting enforced
on the hypervisor side), and storage (guaranteed minimum and maximum IOPS enforced on
the storage side). If using QoS, make sure that the hypervisor or storage system supports this
feature.
• (Optional) Storage Tags. The tags that should be associated with the primary storage for this
disk. Tags are a comma separated list of attributes of the storage. For example "ssd,blue".
Tags are also added on Primary Storage. CloudPlatform matches tags on a disk offering to tags
on the storage. If a tag is present on a disk offering that tag (or tags) must also be present on
Primary Storage for the volume to be provisioned. If no such primary storage exists, allocation
from the disk offering will fail..
• Public. Indicate whether the service offering should be available all domains or only some
domains. Choose Yes to make it available to all domains. Choose No to limit the scope to a
subdomain; CloudPlatform will then prompt for the subdomain's name.

9.1.3. Modifying or Deleting a Service Offering
Service offerings cannot be changed once created. This applies to both compute offerings and disk
offerings.
A service offering can be deleted. If it is no longer in use, it is deleted immediately and permanently. If
the service offering is still in use, it will remain in the database until all the virtual machines referencing
it have been deleted. After deletion by the administrator, a service offering will not be available to end
users that are creating new instances.
9.2. System Service Offerings
System service offerings provide a choice of CPU speed, number of CPUs, tags, and RAM size, just
as other service offerings do. But rather than being used for virtual machine instances and exposed
to users, system service offerings are used to change the default properties of virtual routers, console
proxies, and other system VMs. System service offerings are visible only to the CloudPlatform root
administrator. CloudPlatform provides default system service offerings. The CloudPlatform root
administrator can create additional custom system service offerings.
When CloudPlatform creates a virtual router for a guest network, it uses default settings which are
defined in the system service offering associated with the network offering. You can upgrade the
capabilities of the virtual router by applying a new network offering that contains a different system
service offering. All virtual routers in that network will begin using the settings from the new service
offering.
9.2.1. Creating a New System Service Offering
To create a system service offering:
1. Log in with admin privileges to the CloudPlatform UI.
2. In the left navigation bar, click Service Offerings.
3. In Select Offering, choose System Offering.
4. Click Add System Service Offering.
