Zadara VPSA Driver for OpenStack Manila
=======================================
`Zadaras <https://www.zadara.com>`__ Virtual Private Storage Array (VPSA)
is the first software defined, Enterprise-Storage-as-a-Service. It is an
elastic and private block and file storage system which provides
enterprise-grade data protection and data management storage services.
Manila VPSA driver provides a seamless management capabilities for VPSA
volumes, in this case, NFS & SMB volumes without losing the added value
provided by the VPSA Storage Array/Flash-Array.
Requirements
------------
- VPSA Storage Array/Flash-Array running version 20.12 or higher.
- Networking preparation - the Zadara VPSA driver for Manila support DHSS=False
(driver_handles_share_servers), the driver does not handle
the network configuration, it is up to the administrator to ensure
connectivity from a manila-share node and the Openstack cloud to the
VPSA Front-End network (such as neutron flat/VLAN network).
Supported shared filesystems and operations
-------------------------------------------
Share file system supported
~~~~~~~~~~~~~~~~~~~~~~~~~~~
- SMB (CIFS)
- NFS
Supported operations
~~~~~~~~~~~~~~~~~~~~
The following operations are supported:
- Create a share.
- Delete a share.
- Extend a share.
- Create a snapshot.
- Delete a snapshot.
- Create a share from snapshot.
- Allow share access.
- Manage a share.
.. note::
- Only IP access type is supported
- Both RW and RO access levels supported
Backend Configuration
~~~~~~~~~~~~~~~~~~~~~
The following parameters need to be configured in the [DEFAULT] section of
manila configuration (/etc/manila/manila.conf):
- `enabled_share_backends` = Name of the section on manila.conf used to specify
a backend i.e. *enabled_share_backends = zadaravpsa*
- `enabled_share_protocols` - Specify a list of protocols to be allowed for
share creation. The VPSA driver support the following options: *NFS* or
*CIFS* or *NFS, CIFS*
The following parameters need to be configured in the [backend] section of
manila configuration (/etc/manila/manila.conf):
Driver options
--------------
- `zadara_vpsa_host` = <VPSA - Management Host name or IP address>
- `zadara_vpsa_port` = <VPSA - Port number>
- `zadara_vpsa_use_ssl` = <VPSA - Use SSL connection (default=False)
- `zadara_ssl_cert_verify` = <If set to True the http client will validate
the SSL certificate of the VPSA endpoint (default=True)>
- `zadara_driver_ssl_cert_path` = <Can be used to specify a non default path
to a CA_BUNDLE file or directory with certificates of trusted CAs
(default=None)
- `zadara_access_key` - <VPSA access key>
- `zadara_vpsa_poolname` - <VPSA - Storage Pool assigned for volumes>
- `zadara_vol_encrypt` = <VPSA - Default encryption policy for volumes
(default = True)
- `zadara_gen3_vol_dedupe` = <VPSA - Default encryption policy for volumes
(default = True)>
- `zadara_gen3_vol_compress` = <VPSA - Enable compression for volumes
(default=False)>
- `zadara_share_name_template` = <VPSA - Default template for VPSA share names
(default=OS_share-%s>
- `zadara_share_snap_name_template` = <VPSA - Default template for VPSA share
snapshot names (default=OS_share-snapshot-%s)
- `zadara_default_snap_policy` = <VPSA - Attach snapshot policy for volumes
(default=False)>
- `driver_handles_share_servers` = <DHSS, driver working mode (must be set
to False)>
- `share_driver` = manila.share.drivers.zadara.zadara.ZadaraVPSAShareDriver
