Sustainability SLO for Keystone

The sustainability service level objective (SLO) targets power consumption up to the maximum rated watts for STaaS products deployed to deliver the performance service level instance (PSLI) for unified (excluding the Value performance service level) and block-optimized storage, or per AFX cluster. Learn how Keystone's sustainability goal affects your STaaS setup and how to earn service credits if limits are not met.

Metrics

  • Watts: The power consumed by the storage arrays, or AFX cluster, and as reported by the monitoring tool. The reference maximum power consumption limits are provided in the NetApp Hardware Universe.

  • Tebibyte: The maximum of:

    • the committed capacity + allocated burst capacity for the performance service level, or

    • the effective deployed capacity, assuming a storage efficiency factor of 2:1.

To learn more about storage efficiency ratio, refer to Analyze capacity and storage efficiency savings.

Supported configurations

The sustainability SLO applies to standard Keystone STaaS orders with the following supported configurations:

  • ONTAP AFF A-Series storage arrays or AFX clusters only.

  • Two-node switchless cluster configurations only.

  • Non-commingled configurations only.

  • Non-MetroCluster configurations only.

  • Full and continuous enablement of the monitoring tool and AutoSupport (ASUP) on all storage arrays.

  • Ambient operating environment temperature during power consumption measurement must be between 25°C and 27°C.

Service credits

Note SLAs and guarantees are available on a nomination basis.

If power consumption during a billing period exceeds the maximum rated watts for the deployed STaaS products, then NetApp issues service credits based on committed capacity as follows:

Service credit request

To request a service credit, open a priority 3 (P3) support ticket with NetApp Keystone support within 7 days from the end of the service month, and provide the details as requested in the excel sheet as shown below:

Note the following conditions for service credit requests:

  • NetApp determines whether a service level breach has occurred.

  • You must provide additional information as requested by NetApp, including your wattage consumption data and measurement method.

  • Service credits are calculated based on committed capacity only.

  • Service credits can be applied to the next month's invoice only. They do not apply to expired Keystone subscriptions. To contact NetApp support and open the support case required for a service credit request, see Get help with Keystone.
