EMC Isilon driver
|
|
=================
|
|
|
|
The EMC Shared File Systems driver framework (EMCShareDriver) utilizes
|
|
EMC storage products to provide shared file systems to OpenStack. The
|
|
EMC driver is a plug-in based driver which is designed to use different
|
|
plug-ins to manage different EMC storage products.
|
|
|
|
The Isilon driver is a plug-in for the EMC framework which allows the
|
|
Shared File Systems service to interface with an Isilon back end to
|
|
provide a shared filesystem. The EMC driver framework with the Isilon
|
|
plug-in is referred to as the ``Isilon Driver`` in this document.
|
|
|
|
This Isilon Driver interfaces with an Isilon cluster via the REST Isilon
|
|
Platform API (PAPI) and the RESTful Access to Namespace API (RAN).
|
|
|
|
Requirements
|
|
~~~~~~~~~~~~
|
|
|
|
- PowerScale cluster running OneFS 9.10 or higher
|
|
|
|
Supported shared filesystems and operations
|
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The drivers supports CIFS and NFS shares.
|
|
|
|
The following operations are supported:
|
|
|
|
- Create a share.
|
|
|
|
- Delete a share.
|
|
|
|
- Allow share access.
|
|
|
|
Note the following limitations:
|
|
|
|
- Only IP access type is supported.
|
|
- Only read-write access is supported.
|
|
|
|
- Deny share access.
|
|
|
|
- Create a snapshot.
|
|
|
|
- Delete a snapshot.
|
|
|
|
- Create a share from a snapshot.
|
|
|
|
- Ensure shares.
|
|
|
|
Back end configuration
|
|
~~~~~~~~~~~~~~~~~~~~~~
|
|
|
|
The following parameters need to be configured in the Shared File
|
|
Systems service configuration file for the Isilon driver:
|
|
|
|
.. code-block:: ini
|
|
|
|
share_driver = manila.share.drivers.emc.driver.EMCShareDriver
|
|
emc_share_backend = isilon
|
|
emc_nas_server = <IP address of Isilon cluster>
|
|
emc_nas_login = <username>
|
|
emc_nas_password = <password>
|
|
|
|
Thin Provisioning
|
|
~~~~~~~~~~~~~~~~~
|
|
|
|
PowerScale systems have thin provisioning enabled by default.
|
|
Add the parameter below to set an advisory limit.
|
|
|
|
.. code-block:: ini
|
|
|
|
powerscale_threshold_limit = <threshold percentage value>
|
|
|
|
Restrictions
|
|
~~~~~~~~~~~~
|
|
|
|
The Isilon driver has the following restrictions:
|
|
|
|
- Only IP access type is supported for NFS and CIFS.
|
|
|
|
- Only FLAT network is supported.
|
|
|
|
- Quotas are not yet supported.
|
|
|
|
Driver options
|
|
~~~~~~~~~~~~~~
|
|
|
|
The following table contains the configuration options specific to the
|
|
share driver.
