Isilon Driver

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).

Requirements

Isilon cluster running OneFS 7.2 or higher

Supported Operations

The following operations will be 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 snapshot
Delete snapshot
Create share from snapshot

Backend Configuration

The following parameters need to be configured in the manila configuration file for the Isilon driver:

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> isilon_share_root_dir = <directory on Isilon where shares will be created>

Restart of manila-share service is needed for the configuration changes to take effect.
