Understanding CDMI and S3 Together

How does the Cloud Data Management Interface (CDMI™) International Standard work? Is it possible be to both S3 and CMDI compliant? What security measures are in place with CDMI? How, and where, is CDMI being deployed? These are just some of the topics we covered at our recent SNIA Cloud Storage Technologies (CSTI) webcast, “Cloud Data Management & Interoperability: Why A CDMI Standard Matters.”

CDMI is intended for application developers who are implementing cloud storage systems, and who are developing applications to manage and consume cloud storage.

Q. Can you compare CDMI to S3? Is it possible to be both CDMI and S3 compliant? Is it too complicated?

Why Cloud Standards Matter

Effective cloud data management and interoperability is critical for organizations looking to gain control and security over their cloud usage in hybrid and multicloud environments. The Cloud Data Management Interface (CDMI™), also known as the ISO/IEC 17826 International Standard, is intended for application developers who are implementing or using cloud storage systems, and who are developing applications to manage and consume cloud storage. It specifies how to access cloud storage namespaces and how to interoperably manage the data stored in these namespaces. Standardizing the metadata that expresses the requirements for the data, leads to multiple clouds from different vendors treating your data the same.

Pay Attention to These Cloud Standards

What’s going on in the world of cloud standards? Since the initial publication of the National Institute of Standards and Technology (NIST) definition of cloud computing in NIST SP 800-145 in 2011, international standards development organizations (SDOs) have sought to refine and expand the cloud computing landscape. On February 13, 2020 at our next live SNIA Cloud Storage Technologies Initiative webcast “Cloud Standards: What They Are, Why You Should Care” we will dive into the cloud standards worth noting as Eric Hibbard, standards expert and ISO editor, will discuss:

LTFS Bulk Transfer Standard Q&A

Our recent live SNIA Cloud Webcast “LTFS Bulk Transfer Standard” is now available on-demand. Thanks to all the folks who attended the live event. We did not have time to address all of the questions, so here are answers to them. If you think of additional questions, please feel free to comment on this blog.

Q. The LTFS standard seems to support shared extents between files, and by extension, deduplicated files. Is this a correct assessment, and how does it play in the bulk transfer standard?

A. The LTFS Bulk Transfer Standard supports shared extents as supported by the LTFS standard, which can transparently reduce space used by having multiple references to common data stored on tape (deduplication). This typically happens below the bulk transfer layer, by the software used to read and write the LTFS volumes. At this point, few software packages support this feature due to the wear and latency consequences of read seeks resulting from using this feature.

Q. What is the state of the standard in its lifecycle? (e.g., working group draft, public review, published, etc.)

A. The LTFS standard has been around for some time; more information can be found here at http://www.snia.org/tech_activities/standards/curr_standards/ltfs. The LTFS Bulk Transfer Standard is here at http://www.snia.org/tech_activities/publicreview#ltfsbulk, and is in public review.

Q. The standard seems to be based on the idea of moving physical tapes to the cloud. Is there a definition of a virtual LTFS image that can be moved between systems over the network?

A. Not yet, but that is a great idea we’ll be taking forward in the next versions of the proposal.

Q. One of the barriers to greater use of LTFS in the Cloud is the relative lack of enterprise grade management software that ensures that the tape media is refreshed / upgraded as it ages, that its integrity is periodically checked, that reclamation and compaction is done. It needs open standards for support in standard volume management systems as well. Until these things are in place, LTFS will be interesting largely to specialized industries like film/entertainment, seismic, and bulk transfer & bulk storage — but not about the steady-state use of tape as a true additional layer of the cloud storage hierarchy. Tape with LTFS plus proper management could fill this role — but not until the full lifecycle tape management is available and integrated.

A. The management that is always required for a physical product with a well-defined and finite lifetime is not a unique requirement of LTFS. Tape has a long history of use as a backup and archive medium, and there are a number of tape management products that are commercially available from LTO tape suppliers and independent software companies, as well as open source products. A Google search for “tape management software” will provide you with a number of alternative solutions.

Q. Do you have a list or people that sell LTFS based solutions?

A. No we don’t, but it’s a very good idea, and we’ll investigate it further.
