Tom Barron 90060722a9 doc migration: new directory layout 
This patch introduces a new directory layout
in doc/source in conformance with the OpenStack
manuals project migration spec [1], moves the
existing content in manila/doc/source into the
new directories, and adjusts index files accordingly.

This is the first step in the migration process
as outlined in the spec.

NetApp Clustered Data ONTAP

The Shared File Systems service can be configured to use NetApp Clustered Data ONTAP (cDOT) version 8.2 and later.

Supported Operations

The following operations are supported on Clustered Data ONTAP:

  • Create CIFS/NFS Share
  • Delete CIFS/NFS Share
  • Allow NFS Share access
    • IP access type is supported for NFS.
    • Read/write and read-only access are supported for NFS.
  • Allow CIFS Share access
    • User access type is supported for CIFS.
    • Read/write access is supported for CIFS.
  • Deny CIFS/NFS Share access
  • Create snapshot
  • Delete snapshot
  • Create share from snapshot
  • Extend share
  • Shrink share
  • Manage share
  • Unmanage share
  • Create consistency group
  • Delete consistency group
  • Create consistency group from CG snapshot
  • Create CG snapshot
  • Delete CG snapshot
  • Create a replica (DHSS=False)
  • Promote a replica (DHSS=False)
  • Delete a replica (DHSS=False)
  • Update a replica (DHSS=False)
  • Create a replicated snapshot (DHSS=False)
  • Delete a replicated snapshot (DHSS=False)
  • Update a replicated snapshot (DHSS=False)

Note

DHSS is abbreviated from driver_handles_share_servers.

Supported Operating Modes

The cDOT driver supports both 'driver_handles_share_servers' (DHSS) modes.

If 'driver_handles_share_servers' is True, the driver will create a storage virtual machine (SVM, previously known as vServers) for each unique tenant network and provision each of a tenant's shares into that SVM. This requires the user to specify both a share network as well as a share type with the DHSS extra spec set to True when creating shares.

If 'driver_handles_share_servers' is False, the manila admin must configure a single SVM, along with associated LIFs and protocol services, that will be used for provisioning shares. The SVM is specified in the manila config file.

Network approach

L3 connectivity between the storage cluster and manila host must exist, and VLAN segmentation may be configured. All of manila's network plug-ins are supported with the cDOT driver.

Supported shared filesystems

  • NFS (access by IP address or subnet)
  • CIFS (authentication by user)

Required licenses

  • NFS
  • CIFS
  • FlexClone

Known restrictions

  • For CIFS shares an external Active Directory (AD) service is required. The AD details should be provided via a manila security service that is attached to the specified share network.
  • Share access rules for CIFS shares may be created only for existing users in Active Directory.
  • The time on external security services and storage must be synchronized. The maximum allowed clock skew is 5 minutes.
  • cDOT supports only flat and VLAN network segmentation types.
