NetApp Clustered Data ONTAP
===========================

The Manila Shared Filesystem Management Service can be configured to use
NetApp clustered Data ONTAP version 8.

Network approach
----------------

L3 connectivity between the storage cluster and Manila host should exist, and
VLAN segmentation should be configured.

The clustered Data ONTAP driver creates storage virtual machines (SVM,
previously known as vServers) as representations of Manila share server
interface, configures logical interfaces (LIFs) and stores shares there.

Supported shared filesystems
----------------------------

- NFS (access by IP);
- CIFS (authentication by user);

Required licenses
-----------------

- NFS
- CIFS
- FlexClone

Known restrictions
------------------

- For CIFS shares an external active directory service is required. Its data
  should be provided via security-service that is attached to used
  share-network.
- Share access rule by user for CIFS shares can be created only for existing
  user in active directory.
- To be able to configure clients to security services, the time on these
  external security services and storage should be synchronized. The maximum
  allowed clock skew is 5 minutes.
