Since I have been involved in developing Redbooks and Redpapers for IBM® Storage, Storage Cloud, Storage Systems and Solutions the past few years I have noticed a theme that continues to grow with each project: IBM General Parallel File System (GPFS™). GPFS is more than storage it is about data management. The initial GPFS support in the OpenStack® Cinder Havana Release is evidence of the growing value of GPFS in the Cloud Infrastructure.
If you are thinking it is time to learn more about GPFS here is an introductory video focusing on the value of GPFS: IBM GPFS
If you want to jump ahead and take a look at how GPFS and OpenStack Cinder work to take a look at Bill Owen's video: The Features of IBM GPFS in an OpenStack® Environment. BIll is a Senior Software Developer for IBM Systems & Technology Group, Software Defined Systems - GPFS and OpenStack. His video introduces the OpenStack® Cinder driver support for GPFS. This driver gives architects building public, private, and hybrid clouds access to the features and capabilities of the industry's leading enterprise scale-out file system, and provides a single data plane for all your cloud storage needs.
In our recent Redpaper, IBM Private, Public, and Hybrid Cloud Storage Solutions , we highlight the GPFS support in the OpenStack Cinder Havana Release. The OpenStack® Cinder driver support for GPFS allows you to leverage GPFSs scalable, high performance data and file management solution in your Openstack cloud environment. When you deploy your OpenStack cloud environment with GPFS storage all of your nodes are able to access image, block, object, and file data locally in the shared file system. The figure below shows a high level view of the GPFS single name space in the OpenStack cloud environment.
The GPFS vision for cloud includes:
GPFS as a single scale-out data plane for entire data center
Unifies VM images, block devices, objects, and files
Single name space no matter where data resides
De-clustered parity - GPFS Native RAID (GNR)
Data in best location, on the best tier (performance & cost), at the right time
All in software
As you read through our Storage books keep an eye on GPFS. It has a bright future in the cloud. I look forward to focusing on GPFS projects.
