Admin Guide 3. Storage: NetApp

Supported NetApp Configurations

Abiquo supports NetApp storage in two different configurations:

  1. Physical vFiler 0
  2. vFilers

Physical vFiler 0

Using the NetApp device directly with vfiler0 only means you can work directly with the NetApp. This gives access to the aggregates in vFiler0, which are automatically detected by Abiquo and assigned to Abiquo storage pools.

Set Properties to Calculcate Real Available Space


In the Abiquo scheduler, the free space of an aggregate is now calculated as: 

(availableSpace - (totalAggregateSpace * freeSpaceRatio)) * VolLunRatio 


A new Abiquo Configuration Property has been created:

abiquo.storagemanager.netapp.aggrfreespaceratio 


The default value of this property is 0.05, meaning 5% of space will be kept free on the aggregate.

Note the available space is calculated first, then the Usable space and the Max volumes are calculated for the Abiquo storage pool.

vFilers

Using multiple vFilers on NetApp storage. You can add each vFiler as a storage device with the following constraints:

  • you can only have one username and password per vFiler in Abiquo
  • each vFiler must have a separate management IP and it will also have its own separate Service IP

Abiquo will detect the data volumes created in the vFiler by the Storage Administrator and assign each one to a separate Abiquo storage pool. Each storage pool can be assigned to tier (see    Storage Pool Allocation ) . Abiquo will create virtual storage volumes as LUNs on the data volumes.

Configuration Diagrams

The following diagram shows the two NetApp configurations supported by Abiquo:

See also the VMware configuration and the How to set up a NetApp vFiler for Abiquo Storage Integration pages for further information.

NetApp Authorization Credentials

The NetApp Authorization Credentials are now added in the GUI when you add the NetApp storage device. Abiquo supports one user and password per vFiler storage device. As of version 2.0, you cannot add the NetApp user and password to the abiquo.properties file.

 

NetApp Configuration in ESX and ESXi

Enable iSCSI on the ESX/ESXi host

Log in to the VMware Infrastructure Client

Follow the instructions in this order:

  1. Select your Host or Cluster (depending on your configuration)
  2. Click on the "Configuration" tab
  3. Click on "Storage Adapters" on the left
  4. Choose the iSCSI Software Adapter
  5. Click on "Properties"

As shown in the above screenshot, the adapter should be enabled. 

Click "Configure", then click OK.

If the adapter is not enabled, tick the checkbox to enable it.

Enter a name and alias or use the default ones.
This name is your ESX(i) host IQN.

To use multiple igroups, add the iSCSI Name to the abiquo.properties


Abiquo will access the NetApp API on port TCP 80. This connection is from the Abiquo Remote Services, which are either on the Monolithic Server or a separate Remote Services server.

In addition, the hypervisors and Abiquo V2V services will access the volumes on the storage host through port 3260.
