Datastore Get Iorm Configuration

Deprecated as of vSphere8.0 U3, and there is no replacement for it.

Configuration of storage I/O resource management for the datastore.

Currently we only support storage I/O resource management on VMFS volumes of a datastore.

This configuration may not be available if the datastore is not accessible from any host, or if the datastore does not have VMFS volume. The configuration can be modified using the method ConfigureDatastoreIORM_Task

Returns StorageIORMInfo of type(s) application/json

This response body class contains all of the following: DataObject

{
    "_typeName": "string",
    "enabled": false,
    "congestionThresholdMode": "string",
    "congestionThreshold": 0,
    "percentOfPeakThroughput": 0,
    "statsCollectionEnabled": false,
    "reservationEnabled": false,
    "statsAggregationDisabled": false,
    "reservableIopsThreshold": 0
}

boolean

enabled

Required

Flag indicating whether or not the service is enabled.

string

congestionThresholdMode

Required

Mode of congestion threshold specification For more information, see StorageIORMThresholdModeEnum

integer As int32 As int32

congestionThreshold

Required

The latency beyond which the storage array is considered congested.

If storage I/O resource management is enabled on a datastore, the algorithm tries to maintain the latency to be below or close to this value. The unit is millisecond. The range of this value is between 5 to 100 milliseconds.

integer As int32 As int32

percentOfPeakThroughput

Optional

The percentage of peak throughput to be used for setting congestion threshold of a datastore.

Valid values are between 50 to 100. Default value is 90%

For more information, see StorageIORMInfo.congestionThreshold

boolean

statsCollectionEnabled

Required

Deprecated as of vSphere API 6.5, use StorageIORMInfo.enabled instead.

Flag indicating whether service is running in stats collection mode.

boolean

reservationEnabled

Required

Deprecated as of vSphere8.0 U3, and there is no replacement for it.

Flag indicating whether IO reservations support is enabled.

boolean

statsAggregationDisabled

Optional

Flag indicating whether stats aggregation is disabled.

integer As int32 As int32

reservableIopsThreshold

Optional

Deprecated as of vSphere8.0 U3, and there is no replacement for it.

Storage DRS makes storage migration recommendations if total IOPs reservation for all VMs running on the datastore is higher than specified threshold value.

This value (if present) overrides vim.StorageResourceManager.PodConfigInfo.reservableIopsThreshold
