The Cloud Data Management Interface defines the functional interface that applications will use to create, retrieve, update and delete data elements from the Cloud. As part of this interface the client will be able to discover the capabilities of the cloud storage offering and use this interface to manage containers and the data that is placed in them. In addition, metadata can be set on containers and their contained data elements through this interface.
This interface is also used by administrative and management applications to manage containers, accounts, security access and monitoring/billing information, even for storage that is accessible by other protocols. The capabilities of the underlying storage and data services are exposed so that clients can understand the offering.

CDMI Reference Implementation Working Draft
This early access version of the CDMI Reference Implementation is released for use in developing to the CDMI standard (above). This working draft CDMI Reference Implementation is being released so that developers can get started with integrating CDMI into their products and applications. As the SNIA Cloud Storage Technical Working Group (TWG) continues to create additional functionality, subsequent releases of the CDMI Reference Implementation will be made available.
Get the working draft release.
To provide feedback, please use the SNIA Feedback Portal.
For more information on the CDMI Reference Implementation and specifications, please join the SNIA Cloud Google Group where the experts are available to answer questions about this release.
Video of the CDMI tutorial given at SNW is available here.

Get the new whitepaper on Managing Data Storage in the Public Cloud
The Storage Networking Industry Association has recently published a whitepaper on Managing Data in the Public Cloud.
Public cloud storage can be utilized in many different ways. For example: local data (such as on a laptop) can be backed up to public cloud storage; a virtual disk can be “synched” to the cloud and distributed to other computers; and the cloud can be used as an archive to retain (under policy) data for regulatory or other purposes.
When evaluating cloud implementations, there are three types to be considered: public, private, and hybrid models (many users implement a combination of these). While the Storage Networking Industry Association™ (SNIA) is addressing all three types, this paper discusses public cloud storage solutions and the emerging methods available to best manage these environments.

Get the new whitepaper on Cloud Storage for Cloud Computing
The Storage Networking Industry Association in conjunction with the Open Grid Forum have recently published a whitepaper on Cloud Storage for Cloud Computing. The Cloud has become a new vehicle for delivering resources such as computing and storage to customers on demand.
Rather than being a new technology in itself, the cloud is a new business model wrapped around new technologies such as server virtualization that take advantage of economies of scale and multi-tenancy to reduce the cost of using information technology resources.
This paper discusses the business drivers in the Cloud delivery mechanism and business model, what the requirements are in this space, and how standard interfaces, coordinated between different organizations can meet the emerging needs for interoperability and portability of data between clouds.
To learn more about SNIA's Cloud Data Management Interface (CDMI) standard, and how it works with Cloud Computing standards such as the OGF Open Cloud Computing Interface (OCCI) please download the new whitepaper from one of the following locations:
SNIA Cloud Resources
The SNIA has created the Cloud Storage Technical Work Group for the purpose of developing SNIA Architecture related to system implementations of Cloud Storage technology. The Cloud Storage TWG:
Acts as the primary technical entity for the SNIA to identify, develop, and coordinate systems standards for Cloud Storage.
Produces a comprehensive set of specifications and drives consistency of interface standards and messages across the various Cloud Storage related efforts.
Documents system-level requirements and shares these with other Cloud Storage standards organizations under the guidance of the SNIA Technical Council and in cooperation with the SNIA Strategic Alliances Committee
The SNIA is participating in a group that will coordinate cloud standards across Standards Development Organizations (SDOs). SNIA has existing relationships with DMTF and OGF that have recently been expanded to include cloud standards. The new group has a Cloud Standards Coordination wiki at:
How to get involved
The TWG will also assist and cooperate with other SNIA TWGs in their efforts to incorporate Cloud Storage into their standards work.
