NetApp iSCSI direct driver for clustered Data ONTAP

The NetApp iSCSI direct driver for clustered Data ONTAP is a driver interface from OpenStack to clustered Data ONTAP storage systems for provisioning and managing the SAN block storage entity, that is, NetApp LUN using iSCSI protocol.

The NetApp iSCSI direct driver for clustered Data ONTAP does not require additional management software to achieve the desired functionality. It uses NetApp APIs to interact with the clustered Data ONTAP.

Configuration options for the clustered Data ONTAP direct driver

Set the volume driver to the clustered Data ONTAP direct driver by setting the volume_driver option in cinder.conf as follows:

  volume_driver=cinder.volume.drivers.netapp.iscsi.NetAppDirectCmodeISCSIDriver

Table 11.5. List of configuration flags for clustered Data ONTAP iSCSI direct driver
Flag name	Type	Default	Description
`netapp_server_hostname`	Mandatory		The cluster management IP address for the clustered Data ONTAP.
`netapp_server_port`	Mandatory		The clustered Data ONTAP port to use for communication. As a custom 80 is used for http and 443 is used for https communication. The default ports can be changed if other ports are used for ONTAPI on clustered Data ONTAP.
`netapp_login`	Mandatory		Login user name for clustered Data ONTAP management.
`netapp_password`	Mandatory		Login password for clustered Data ONTAP management.
`netapp_transport_type`	Optional	http	Transport protocol for communicating with clustered Data ONTAP. Supported protocols include http and https.
`netapp_size_multiplier`	Optional	1.2	The quantity to be multiplied to the requested OpenStack volume size which then is used to make sure that the final size is available on clustered Data ONTAP Vserver before creating OpenStack volume on the same.
`netapp_vserver`	Optional	openstack	The Vserver on the cluster on which provisioning of OpenStack volumes will be done.
