adaptive

Adaptive QoS policy-groups define measurable service level objectives (SLOs) that adjust based on the storage object used space and the storage object allocated space.

Name Type Description

absolute_min_iops

integer

Specifies the absolute minimum IOPS that is used as an override when the expected_iops is less than this value. These floors are not guaranteed on non-AFF platforms or when FabricPool tiering policies are set.

expected_iops

integer

Expected IOPS. Specifies the minimum expected IOPS per TB allocated based on the storage object allocated size. These floors are not guaranteed on non-AFF platforms or when FabricPool tiering policies are set.

peak_iops

integer

Peak IOPS. Specifies the maximum possible IOPS per TB allocated based on the storage object allocated size or the storage object used size.

fixed

QoS policy-groups define a fixed service level objective (SLO) for a storage object.

Name Type Description

capacity_shared

boolean

Specifies whether the capacities are shared across all objects that use this QoS policy-group. Default is false.

max_throughput_iops

integer

Maximum throughput defined by this policy. It is specified in terms of IOPS. 0 means no maximum throughput is enforced.

max_throughput_mbps

integer

Maximum throughput defined by this policy. It is specified in terms of Mbps. 0 means no maximum throughput is enforced.

min_throughput_iops

integer

Minimum throughput defined by this policy. It is specified in terms of IOPS. 0 means no minimum throughput is enforced. These floors are not guaranteed on non-AFF platforms or when FabricPool tiering policies are set.

min_throughput_mbps

integer

Minimum throughput defined by this policy. It is specified in terms of Mbps. 0 means no minimum throughput is enforced.

svm

Name Type Description

_links

_links

name

string

The name of the SVM.

uuid

string

The unique identifier of the SVM.

qos_policy
