Provisioning storage to the host is done by creating a volume on a specific capacity pool and mapping it to the host or cluster.
- You can either map an existing volume or create a new volume.
- Host PowerTools also automates the datastore creation. (optional)
This task performs the following actions:
- Creates a volume in InfiniBox.
- Maps it to the select host or cluster.
- Initiates a storage HBA rescan.
- Creates a datastore over the volume. (optional)
Creation a datastore
In order to create a new datastore:
In vSphere Web client select the desired host or cluster.
- Locate the INFINIDAT view. Follow the instructions here: Locating the Infinidat View.
- The available operations are Map and Create, as you can either map an existing volume, or create new volume(s).
- The Create Volume screen opens.
- Enter the following information:
- Volume name - A default volume name is displayed on the screen. You may provide another name.
- Size - Set a size for the volume. Select the unit between GB and TB.
- Thin - Check to create a thin-provisioned volume.
If this checkbox is left unchecked, the volume will be thick-provisioned.
- Pool - Select a pool to associate the volume with. Only pools that are available to the user are displayed.
Note that the available space on the storage system is indicated.
- Create Series - Set the number of volumes that will be created
- If more that a single volume is created, the volume name that was entered above will serve as a prefix to the name of the volume series.
- More information about creating a series of volumes is available on InfiniBox documentation: Creating a volume
- LUN - automatically allocated unless set by the user
- Create datastore - Check in order to create a datastore for the volume.
- Uncheck If you prefer to create the datastore later on, or if the provisioned space will be used for another purpose, such as Raw Device Mapping (RDM), disks, or existing datastore extent.
- Set device name to volume name - Set the volume name to have the name of the VMware container of virtual machines.
- Click Continue.
The Create Volume screen displays the operations that are about to take place.
- Click Start.
The progress of the volume creation process is indicated on the screen.
- Click Done.
The volume is created and is available in the volumes table.
- If a datastore was created, it is ready for use.
Virtual machines considerations
For optimal performance, It's recommended to use Lazy-zeroed thick provisioning for all hard disks. (rather than thin)
