Datastore tiers
In private cloud, use datastore tiers to group hypervisor datastores and price them according to service levels.
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.
In widgets on the Dashboard, the platform will display tiers that are allowed, and tiers that are disabled.
Abstract datastore tiers
To work with the same service levels in multiple datacenters, and public cloud, use Abstract datastore tiers to group storage service levels.
You can then create limits for an enterprise in each storage service level.
You can display abstract datastore tiers on the dashboard, with usage and limits by enterprise. See Dashboard widgets. Note that this widget will display the abstract datastore tiers that are enabled and allowed to the enterprise, and also disabled tiers.
