A&AI Schema Changes

Image RemovedRequirements that are kept in mind are :

  • Expose HW capability of various CPU architecture (Intel x86,  ARM etc...) in generic fashion.
  • Provide flexibility to expose CPU architecture and vendor specific features.
  • Support for multiple Clouds such as Openstack clouds, AWS Cloud,  Azure Cloud etc...
  • No hardcoding of HPA feature names OR attribute names in ONAP (other than Multi-Cloud plugin)
  • HPA Impact on the AAI Project
  • Please refer to HPA Requirement & Capability Specification

Following format is used to represent the HPACapability:

  • Data centers typically have flavors (openstack calls them flavors,  Azure calls them VM sizes and AWS calls them as Instance types). Each flavor is represented by hardware features.   When these are discovered by ONAP,  there are few ways to represent them in A&AI DB. 
    • Approach 1:
      • flavors as children to the cloud-region (Already existing)
      • Represent HPA capabilities under each flavor (HPA capabilities as children of each flavor)
    • Approach 2:
      • flavors as children to the cloud-region (Already existing). Also, represent HPA capabilities also children to the cloud-regions.
      • Then provide relationship between flavors and capabilities.
    • Approach 3:
      • Approach 1 +
      • Create another tree with capability to region+flavor list.
    • Which approach to follow?  Some guidance from A&AI team.  Requirement is this:
      • During VNF instantiation, OOF gets hold of hardware requirements and based on that requirements, it needs to find out the best cloud-region and flavor.
      • Would Approach 3 seem possible?
  • Each HPACapability is defined as 
    {HPACapability-id,HPAFeature, Schema Version, hardware-architecture, [List of HPAAttributes] - names and values}
  • HPAFeatureAttribute is <hpaAttributeKey, hpaAttributeValue>
  • Refer Supported HPA Capability Requirements(DRAFT) for more specific Capability names and values.

HPA Feature Definition

Requirements that are kept in mind are :

  • Expose HW capability of various CPU architecture (Intel x86,  ARM etc...) in generic fashion.
  • Provide flexibility to expose CPU architecture and vendor specific features.
  • Support for multiple Clouds such as Openstack clouds, AWS Cloud,  Azure Cloud etc...
  • No hardcoding of HPA feature names OR attribute names in ONAP (other than Multi-Cloud plugin)

Following table provides HPA features and attributes.  Also, it describes matching constraints for each HPA feature. These constrains are applied while finding the best compute-group for placing VNFC.

Following format is used to represent the HPA feature name:

<Hardware or Software feature>-<Generic feature or CPU architecture/vendor specific featuers>-<feature name>

Attributes are represented as:
