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 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 snapshot
  • Delete snapshot
  • Create share from snapshot
  • Extend share

Backend Configuration

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.

Restrictions

The Isilon driver has the following restrictions:

  • Only IP access type is supported for NFS and CIFS.
  • Only FLAT network is supported.
