Service levels

NetApp Keystone Flex Subscription (Flex Subscription) offers capacity at predefined service levels or performance service levels.

Each service level (service level) is defined by its I/O density, which is the ratio of performance (input/output operations per second [IOPS]) and used storage (TiB of stored data) which is IOPS/TiB.

Each volume managed by the Flex Subscription services is associated with a service level. All I/O operations and all used storage used on the respective volume are factored into the volume’s I/O density calculation.

The below table defines the service levels.

Service levels for difference storage types

The service levels for file, block, and object storage are listed here.

I/O density calculations at the volume level are reported to show peak I/O density during the prior week. The peak performance is determined on an hourly time interval. I/O density reports by volume are generated monthly to gauge adherence to the respective service levels.
