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).


  • Isilon cluster running OneFS 7.2 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.

Back end configuration

The following parameters need to be configured in the Shared File Systems service 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>


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.
