There are two types of allocation rules: Global rules apply to all datacenters and Datacenter rules apply to the selected datacenter. 

Manage allocation rules with the API

Tip

API Documentation

For the Abiquo API documentation of this feature, see Abiquo API Resources and the page for this resource RulesResource.

...

The platform uses allocation rules to control the scheduling of resources in datacenters, although your virtualization technology must manage the use of the resources. For details of the allocation process, see the Virtual machine allocation section. 

You can create the following types of load balance rules:

...

  1. Go to Infrastructure --> Private → select Datacenter → Allocation rules → Global

  2. Click the + add button

  3. Select Restrict shared server rule 

  4. Select the two enterprises that must not share a physical server. The cloud admin must configure the rules properly to customize VM deployments.

Rule type

Select Load level compute

Rack

Select All or a specific rack

Server

Select All or a specific server.

If you are using a cluster as a physical machine, to create rules for the cluster, select the Server option

Cluster

If you are using vCenter with ESXi, the platform detects the clusters. Select a specific cluster

A cluster rule affects all hosts irrespective of their state, for example, it applies to hosts that are powered off.

Aggregate

Select to create a rule for the sum of all resources in a group (datacenters, racks, or clusters). This means that the platform will sum all of the resources in the group and calculate the load level percentage of the total in order to determine the available resources for the group.

Service Port

The port used by the cloud nodes to connect to the storage technology

RAM

Percentage usage of memory to allow. We DO NOT recommend the overallocation of RAM

CPU cores

Percentage usage of CPU cores to allow. We DO NOT recommend the oversubscription of CPU cores
