Manage datastore service levels with 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.

In widgets on the Dashboard, the platform will display tiers that are allowed, and tiers that are disabled.

1. Go to Infrastructure → Private 

2. Select a datacenter

3. Go to Servers view → Datastore tiers

To manage the datastores of the hypervisor in tiers: 

1. Go to Servers

2. Edit the hypervisor

To display a list of enterprises with access to a datastore tier, edit the tier and go to Enterprise access.

When you deploy VMs, the platform will copy VM templates to the hypervisor datastore and you can also create hard disks and allow users to create hard disks on the hypervisor datastores.

1. Go to Infrastructure → Private → select datacenter → Datastore tiers

2. Click the + Add button

3. Enter the Name and Description

4. Optionally select an Abstract datastore tier to add the tier to a group to control storage service levels for tenants in more than one datacenter. See Abstract datastore tiers for storage service levels

5. Click Save

The platform will create the tier and allow access to all future enterprises that you create. 

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:

• all enterprises

• enterprises in a datacenter

To modify enterprise access for ALL enterprises, Infrastructure → Private → select Datacenter → Datastore tiers → create or edit datastore tier → Enterprise access

To display a list of enterprises that currently have access to a datastore tier:

1. Go to Infrastructure → Private → select Datacenter → Datastore tiers → edit datastore tier → Enterprise access

2. Click Cancel or select Do not change enterprise access

   

You can control access to datastore service levels with datastore tiers. 

To allow or prohibit access to a datastore tier for an individual enterprise

1. Go to Users → edit enterprise → Datacenters → edit allowed datacenter → Datastore tiers

2. Drag datastore tiers to the Allowed or Prohibited lists for this enterprise

3. Click Accept to save the Enterprise datacenter resources

You can also set limits for the tenant for the datastore tiers within each datacenter. See Configure an enterprise in a cloud location#Setallocationlimitsforatenantinadatacenterorregion

To add multiple datastores to a tier:

1. Go to Infrastructure → Private → select datacenter → Datastore tiers 

2. Select a datastore tier

3. Click the + add button in the Datastores pane on the right

   

4. From the popup list, select the Datastores to add

   

5. Click Add

You can also add datastore tiers to services levels when you create or edit a hypervisor. See Compute in datacenters
