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).
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 is supported.
Deny CIFS/NFS share access
Create snapshot
Delete snapshot
Create share from snapshot
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> 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.
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.
Configuration options specific to this driver are documented here: Table 3.11, “Description of EMC Share Drivers configuration options”.
