Storage capability profiles and VASA Provider

VASA Provider for clustered Data ONTAP enables you to create storage capability profiles. You can then match the set of capabilities in the profile to a datastore. Having storage capability profiles simplifies provisioning storage and ensures consistency across the storage.

Each storage capability profile defines Service Level Objectives (SLOs) and associates these SLOs with storage features, such as disk type, high availability, disaster recovery, performance options, deduplication, and space efficiency. You can assign the profile to any datastore whose attributes match the profile. As a result, storage capability profiles enable you to define and maintain consistency in your storage SLOs.

You can also specify a storage capability profile when you use Virtual Storage Console for VMware vSphere to provision virtual machines. The provisioning wizard filters information based on that profile so you can easily select datastores that match the storage requirements for the virtual machines.

In addition, you can manually map a profile to any datastore that has resources matching the profile.

VASA Provider continuously monitors these datastores for compliance with the associated profiles. If the attributes associated with a datastore change and cause it to fall out of compliance, VASA Provider displays an alarm.

You set up and manage storage capability profiles from the VASA Provider for clustered Data ONTAP section of the VSC GUI. There are several methods for creating a storage capability profile:

By default, VASA Provider provides three standard storage capability templates to address the different needs of companies. You can use these templates to create the appropriate profiles for your storage environment. The following table provides information about the default templates:

Template Storage SLO
Gold-Template The Gold template targets the needs of business critical storage. It has the following features:
  • Very high performance
  • Performance isolation
  • Disaster recovery isolation
  • Long retention of the storage
Silver-Template The Silver template targets the needs of departmental storage. It has the following features:
  • High performance
  • Performance isolation
  • Disaster recovery on a group
  • Short retention of the storage
Bronze-Template The Bronze template supports other applications. It has the following features:
  • High capacity
  • No disaster recovery
  • No retention

To view the settings for these templates, go to the VASA Provider section in the VSC GUI. You select the template on the Storage Capability Profile page. You can view the template on the Summary page.
