In the Service Provider Admin Portal, you can change the I/O operations per second (IOPS) settings of your provider VDC storage policy. By default, the organization VDCs to which the policy is published inherit the provider VDC storage policy settings.

The screenshot shows the Edit Storage Policy Settings modal.

Procedure

  1. From the top navigation bar, select Resources and click Cloud Resources.
  2. In the left panel, select Provider VDCs, and click the name of the target provider virtual data center.
  3. Under Policies, select Storage .
  4. Click the radio button next to the target storage policy, and click Edit Settings.
  5. If you want to limit the IOPS, turn on the IOPS Limiting Enabled toggle.
  6. If you want IOPS to be considered during placement, turn on the Impact Placement toggle.
    If the Impact Placement toggle is turned on, VMware Cloud Director provides IOPS load balancing across datastores. When you set IOPS settings for a disk, VMware Cloud Director considers datastores with enough IOPS capacity for the selected disk. If the Impact Placement toggle is turned off, you do not need to set IOPS capacities per datastore and you can use Storage DRS clusters.
  7. Configure the maximum and default IOPS settings and click Save.
    Option Description
    Maximum Disk IOPS The maximum I/O operations per second (IOPS) for all disks associated with this storage policy.
    Disk IOPS Per GB Max The maximum IOPS that can be assigned to any disk associated with this storage policy based on the size of the disk (in GB). This value is also the default IOPS value that VMware Cloud Director uses for any disk associated with this policy. If the value is zero, VMware Cloud Director uses the Default Disk IOPS as the default IOPS for the disks associated with this storage policy.
    Default Disk IOPS The default IOPS to apply to any disk associated with the storage policy. VMware Cloud Director uses this default only when the Disk IOPS Per GB Max value is zero.
    IOPS Limit The sum of IOPS across all disks associated with this policy cannot be greater than this value.

Results

The new storage policy settings apply to all organization VDCs to which this policy is published.
