NetApp Clustered Data ONTAP
The Shared File Systems service can be configured to use
NetApp Clustered Data ONTAP (cDOT) version 8.2 and later.
Supported Operations
The following operations are supported on Clustered Data ONTAP:
- Create CIFS/NFS Share
- Delete CIFS/NFS Share
- Allow NFS Share access
- IP access type is supported for NFS.
- Read/write and read-only access are supported for NFS.
- Allow CIFS Share access
- User access type is supported for CIFS.
- Read/write access is supported for CIFS.
- Deny CIFS/NFS Share access
- Create snapshot
- Delete snapshot
- Create share from snapshot
- Extend share
- Shrink share
- Manage share
- Unmanage share
- Create consistency group
- Delete consistency group
- Create consistency group from CG snapshot
- Create CG snapshot
- Delete CG snapshot
- Create a replica (DHSS=False)
- Promote a replica (DHSS=False)
- Delete a replica (DHSS=False)
- Update a replica (DHSS=False)
- Create a replicated snapshot (DHSS=False)
- Delete a replicated snapshot (DHSS=False)
- Update a replicated snapshot (DHSS=False)
Note
DHSS is abbreviated from driver_handles_share_servers.
Supported Operating Modes
The cDOT driver supports both ‘driver_handles_share_servers’ (DHSS)
modes.
If ‘driver_handles_share_servers’ is True, the driver will create a storage
virtual machine (SVM, previously known as vServers) for each unique tenant
network and provision each of a tenant’s shares into that SVM. This requires
the user to specify both a share network as well as a share type with the DHSS
extra spec set to True when creating shares.
If ‘driver_handles_share_servers’ is False, the manila admin must configure a
single SVM, along with associated LIFs and protocol services, that will be
used for provisioning shares. The SVM is specified in the manila config file.
Network approach
L3 connectivity between the storage cluster and manila host must exist, and
VLAN segmentation may be configured. All of manila’s network plug-ins are
supported with the cDOT driver.
Supported shared filesystems
- NFS (access by IP address or subnet)
- CIFS (authentication by user)
Known restrictions
- For CIFS shares an external Active Directory (AD) service is required. The AD
details should be provided via a manila security service that is attached to
the specified share network.
- Share access rules for CIFS shares may be created only for existing users
in Active Directory.
- The time on external security services and storage must be synchronized. The
maximum allowed clock skew is 5 minutes.
- cDOT supports only flat and VLAN network segmentation types.
The manila.share.drivers.netapp.common.py Module
Unified driver for NetApp storage systems.
Supports multiple storage systems of different families and driver modes.

class NetAppDriver
Bases: object
“NetApp unified share storage driver.
Acts as a factory to create NetApp storage drivers based on the
storage family and driver mode configured.
