The EMC manila driver framework (EMCShareDriver) utilizes EMC storage products to provide shared filesystems to OpenStack. The EMC manila driver is a plugin based driver which is designed to use different plugins to manage different EMC storage products.
The Isilon manila driver is a plugin for the EMC manila driver framework which allows manila to interface with an Isilon backend to provide a shared filesystem. The EMC driver framework with the Isilon plugin 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).
Isilon cluster running OneFS 7.2 or higher
The following operations are supported on an Isilon cluster:
Create CIFS/NFS Share
Delete CIFS/NFS Share
- Allow CIFS/NFS Share access
Only IP access type is supported for NFS and CIFS
Only RW access supported
Deny CIFS/NFS Share access
Create share from snapshot
The following parameters need to be configured in the manila configuration file for the Isilon driver:
share_driver = manila.share.drivers.dell_emc.driver.EMCShareDriver
driver_handles_share_servers = False
emc_share_backend = isilon
emc_nas_server = <IP address of Isilon cluster>
emc_nas_server_port = <port to use for Isilon cluster (optional)>
emc_nas_login = <username>
emc_nas_password = <password>
emc_nas_root_dir = <root directory path to create shares (e.g./ifs/manila)>
Restart of manila-share service is needed for the configuration changes to take effect.
The Isilon driver has the following restrictions:
Only IP access type is supported for NFS and CIFS.
Only FLAT network is supported.
