Introduction to datastore tiers

Excerpt
nameIntroduction to datastore tiers

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.

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

Display datastore tiers

Excerpt
nameDisplay datastore tiers

To display datastore tiers for hypervisor storage service levels:

  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.

Create datastore tiers

...

To create combine storage service levels across the cloud to set cloud storage limits for tenants, use abstract datastore tiers.

Set access to tier service levels for datastores

Excerpt
nameSet 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:

  1. To modify enterprise access for

ALL

  1. all enterprises,

  2. Go to Infrastructure → Private

→ select Datacenter → Datastore tiers → create

  2. Select a datacenter and go to Datastore tiers

  3. Create or edit datastore tier

→

  1. and go to Enterprise access

  2. Select Allow all enterprises or Restrict all enterprises

Note

  • 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

Allow a tenant to use datastore tiers in a datacenter

Excerpt
nameAllow 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

  1. Go to Users → edit enterprise → Datacenters → edit allowed datacenter → andedit an enterprise

  2. Go to Datacenters and edit an allowed datacenter

  3. Go to Datastore tiers

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

  5. Click Accept to save the Enterprise datacenter resources

Image Removed Allow an enterprise to use datastore tiersImage Added

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

Note

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

Excerpt
nameEdit 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:

  1. Go to Infrastructure → Private → select datacenter →

  2. Select a datacenter and go to Datastore tiers 

  3. Select a datastore tier

  4. Click In the + add button in the Datastores pane on the right

  6. Click Add

Note

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
