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.
