WARN  [ServerConnection on port 10000 Thread 14] com.vmware.vcops.wlp.evaluator.PlacementImpactHandler.canSupportLoad - There is no room for demand,  provider = XXXXXXXXX, providerResContainer = mem|demand, capacity = 4.831040088E8, threshold = 80.0, overhead = 4.3559489759999967E8, demandLimit = -4.9111690559999645E7

Environment

Aria Operations 8.18.X

Cause

The WLP (Workload Placement) engine will not place a deployment on any Datastore / Datastore cluster / Cluster where placement will cause the objects Workload threshold to exceed the value configured for this object in the Aria Operations policy as described in the Resolution below.

Resolution

vCenter:

• Find the Datastore / Datastore Cluster which you intend to deploy to and confirm that the usage is exceeding 80% (Aria Operations default Workload threshold)
• If Datastore usage exceeds 80%, either add additional capacity to this Datastore / Datastore Cluster or proceed with the steps below.

Aria Operations:

• Search for the Datastore / Datastore Cluster object which you intend to deploy to.
• On the top right hand corner of the window, click on "POLICY", then "View Policy".
  
  
  
  
• Once the policy opens, click on "EDIT POLICY", then open the "Capacity" tile
• In the "Capacity Thresholds and Metrics" section select the Datastore / Datastore Cluster / Cluster Compute Resource objects and increase the Workload thresholds for each so that they will allow the deployment.
  
  
  Example: Datastore Cluster object
