Because the Dell EMC Isilon driver has now been renamed to PowerScale, we should change all the relevant parts of the code. Implements: blueprint powerscale-rename-manila Change-Id: Ic377d336972c55ce3cd59549c6b1c034e062bc52 Signed-off-by: cuiyeliu <cuiye.liu@dell.com>

Dell PowerScale driver
The EMC Shared File Systems driver framework (EMCShareDriver) utilizes Dell 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 Dell storage products.
The PowerScale driver is a plug-in for the EMC framework which allows
the Shared File Systems service to interface with an PowerScale back end
to provide a shared filesystem. The EMC driver framework with the
PowerScale plug-in is referred to as the PowerScale Driver
in this document.
This PowerScale Driver interfaces with an PowerScale cluster via the REST PowerScale 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 PowerScale driver:
share_driver = manila.share.drivers.emc.driver.EMCShareDriver
emc_share_backend = powerscale
emc_nas_server = <IP address of PowerScale 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.
powerscale_threshold_limit = <threshold percentage value>Restrictions
The PowerScale 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.
