|
||||
===========================
|
||||
|
||||
The Manila Shared Filesystem Management Service can be configured to use
|
||||
NetApp clustered Data ONTAP version 8.
|
||||
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
|
||||
|
||||
Supported Operating Modes
|
||||
-------------------------
|
||||
|
||||
The cDOT driver supports both 'driver_handles_share_servers' (:term:`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 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.
|
||||
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);
|
||||
- CIFS (authentication by user);
|
||||
- NFS (access by IP address or subnet)
|
||||
- CIFS (authentication by user)

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.
|
||||
- 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.
