In private cloud, to group hypervisor datastores and price them according to service levels, use datastore tiers.
When you use tiers, administrators or cloud users can choose the service level for VM hard disks at the level of VM templates, virtual datacenters, and VMs.
When you perform VM or storage moves outside of Abiquo, the platform will synchronize disks to their new datastore tiers.
If you do not enable datastore tiers feature, all datastore disks will be created in the "Default Tier".
You can add datastores to a tier when you add a hypervisor to the platform, or from the Datastore tiers tab.
You can only add datastores to datastore tiers if they do not have any managed VM disks on them or if none of the disks are in a tier.
To restrict the use of datastore tiers, you can make them:
Not allowed: an enterprise cannot use a tier that is not allowed, and they cannot create disks in this tier.
Disabled: the administrator can disable a tier, for example, for maintenance, migration, or administrative reasons.

This section describes how to define access to datastore tiers. When you create a datastore tier, by default the platform will allow access to the current enterprise only. To allow access to different service levels you can set access for these levels:
To modify enterprise access for ALL enterprises, Infrastructure → Private → select Datacenter → Datastore tiers → create or edit datastore tier → Enterprise access
