We are proud to announce that the IBM Storage Driver for OpenStack has been recently upgraded to a new version - 1.6.0. This version brings support for OpenStack Liberty release, as well as for DS8870 microcode version 7.5 SP3 and DS8880 version 8.01. In addition, this release introduces the XIV and Spectrum Accelerate support for the OpenStack consistency groups. It also brings in the RESTful API that replaced the Java-based ESSNI driver in DS8000 storage systems.

We are happy to announce the release of an updated OpenStack Cinder driver for IBM Spectrum Virtualize, Storwize Family and FlashSystem V9000. This release complies with OpenStack Liberty specifications, emphasizing IBM's continuous commitment to making the cutting-edge OpenStack features available for IBM storage customers.
Another change is the enabling or disabling the fast format option during thick volume creation. As some volume operations are disabled until fast format is completed, the customer can now skip the fast format, when creating a thick volume. This makes the volume operational immediately after its creation.
Version 7.6 of IBM Spectrum Virtualize and Storwize Family will be supported after its release with no additional Cinder driver code change.
In this post we would like to introduce the latest version of the IBM Storage Driver for OpenStack, which we released on January 31st, 2013.

To put in a few words, OpenStack is an open-source software platform for building private and public cloud environments. The IBM driver is a software component that enables storage provisioning of the IBM XIV Storage Systems in OpenStack cloud environments.
The latest IBM driver version was preceded by an earlier one (1.1.0), which enabled basic storage provisioning operations, such as volume creation and deletion from OpenStack Cinder Node, and volume attachment to OpenStack VMs.
The new release (1.1.1) further enhances the integration between OpenStack and IBM XIV Storage System by adding support for XIV volume snapshot functions.
For example, let's look at the following OpenStack Web UI management page:
In this example, if you want to create a snapshot of ‘vol1’ on IBM XIV Storage System, you can use the ‘Create Snapshot’ action using either OpenStack CLI or Web UI.
Here is your created snapshot, as can be viewed from the XIV GUI:
Similarly, you can use OpenStack's ‘Create volume from snapshot’ action to create a volume based on an existing snapshot.
An additional ease-of-use enhancement in version 1.1.1 is the new unattended installation option, allowing no user interaction during the installation, perfect for automating the installation process. You can use the following command format to install the IBM driver in an unattended mode:
Cinder-node# ./install.sh –s –a <xiv_address> –u <username> –p <password> –o <pool_name>
The IBM Storage Driver for OpenStack can be downloaded here along with the Installation Guide and Release Notes.
Whenever you choose to integrate your IBM XIV Storage System with an OpenStack cloud environment, our driver is available to help you achieve this goal. We are happy to provide this newer version that further facilitates and enhances the utilization of your XIV storage resources and capabilities in your cloud environment.
As always, you are welcome to share your thoughts with us.
