This page describes how to manage datastore tiers to offer storage service levels in private cloud datacenters.
For details of how to recommend or enforce the use of datastore tiers, see Manage datastore storage policies
For a general introduction, see About datastore tiers
Create datastore tiers
To create a datastore tier:
Privileges: Access infrastructure view and Private DCs, View datacenter details, Manage storage elements
Go to Infrastructure → Private
Select a datacenter → Datastore tiers
Click the + Add button
Enter the Name and Description
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
Click Save
The platform will create the tier and allow access to all future enterprises that you create.
Set access to tier service levels for datastores
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
Changes here will override the settings defined for an individual enterprise
You cannot restrict the access of enterprises that have already created disks in the tier
To display a list of enterprises that currently have access to a datastore tier:
Go to Infrastructure → Private → select Datacenter → Datastore tiers → edit datastore tier → Enterprise access
Click Cancel or select Do not change enterprise access
Allow a tenant to use datastore tiers in a datacenter
You can control access to datastore service levels with datastore tiers.
To allow or prohibit access to a datastore tier for an individual enterprise
Go to Users → edit enterprise → Datacenters → edit allowed datacenter → Datastore tiers
Drag datastore tiers to the Allowed or Prohibited lists for this enterprise
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
Troubleshooting
You cannot restrict the access of enterprises that have already created disks in the tier
Changes in Infrastructure view to the Datastore tiers on the Enterprise access tab will override these settings
Edit a datastore tier and add multiple datastores
You can edit a datastore tier and select multiple hypervisor datastores to add them to this service level.To add multiple datastores to a tier:
Go to Infrastructure → Private → select datacenter → Datastore tiers
Select a datastore tier
Click the + add button in the Datastores pane on the right
From the popup list, select the Datastores to add
Click Add
Troubleshooting
Generally, you cannot add datastores with managed VMs deployed on them to a datastore tier
Exception: if a datastore with managed VMs deployed on it does not have a tier (e.g. as a result of datastore synchronization), you can assign it to a tier and the platform will automatically assign all disks to that tier
You can also add datastore tiers to services levels when you create or edit a hypervisor. See Compute in datacenters
