Feature Updates

Nimble Storage Driver

The Nimble storage driver is currently available in a limited capacity, see Known Issues for more information.

The Nimble storage driver enables a host to configure and manage Nimble Storage array features using Block Storage interfaces.

The Nimble storage driver uses iSCSI only. Fibre Channel is not supported.

The Nimble storage driver supports the following operations:

  • Create, delete, clone, attach, and detach volumes.
  • Create and delete volume snapshots.
  • Create a volume from a snapshot.
  • Copy an image to a volume.
  • Copy a volume to an image.
  • Extend a volume.
  • Get volume statistics.
  • Manage and unmanage a volume.

    The capacity report downloads to your local computer in a text file named YYYY-MM-DD-capacity-report.txt.

You can now see full names for AZs in the Dashboard. For example an AZ named examp1 will display Example Company Production Environment 1 in reports.

New Guest Operating System Support

You can now run Windows 2016 in a fully supported configuration.

Bug Fixes

The current release includes the following bug fixes:

  • During live block migration, VM migrations with attached volumes will no longer stop unless there is a risk of data corruption caused by the storage platform.
  • Network Usage and Network Packets are now displayed in the Hypervisors and Controllers panels.
  • Running openstack volume list --all-projects now displays accurately when there are multiple pages.
  • Capacity reports now function correctly. See Capacity Planning for more information about Capacity reports.

Known Issues

The following issues have been detected in certain edge-case tests for the Nimble Storage Driver:

  • When performing a bulk creation of volumes, some volumes were not able to attach to the VM.
  • After deleting a server, attached volumes may remain IN USE and cannot be deleted.
