Cloud computing is defined as the use of computing services and resources (hardware and software) that are delivered over a network, typically Ethernet. OpenStack is being developed as an industry standard Cloud computing project. OpenStack is a global collaboration of developers and cloud computing technologists producing the ubiquitous open source cloud computing platform for public and private clouds. To learn more about OpenStack, refer to the project website at:
With the availability of the IBM Storage Driver for OpenStack, the IBM XIV Storage System offers a range of capabilities that enable more effective storage automation deployments into private or public clouds. Enabling OpenStack with XIV allows for storage to be made available whenever needed without the traditional associated cost of highly skilled administrators and infrastructure .
After the driver is installed on the OpenStack Cinder (OpenStack Block Storage) nodes, XIV storage volumes can be allocated by the Cinder nodes to the Nova-compute nodes in the OpenStack cloud environment. Virtual machines on the Nova-compute nodes can then utilize these storage resources.
The driver controls the creation and deletion of volumes on the XIV Storage System Gen3, and manages mappings (attach or detach ) of volumes with Virtual Machines (VMs) running in OpenStack. Access to the XIV volumes is over an iSCSI connection protocol.

Note also that illustrations in this paper are based on the Openstack Folsom release. This release offers two options in terms of block storage: Nova-Volumes and Cinder. Both are nearly identical in terms of functionality, APIs, and even the general theory of operation. Remember, however, that the Nova-Volumes option is deprecated and to be removed at the release of Grizzly.
