SNIA Draft Technical Work available for Public Review
During the development of technical work, the SNIA may make available a Work-in-Progress DRAFT version for public review & feedback. Work-in-Progress DRAFTS are not endorsed by the SNIA for commercial shipping product implementation, but rather for review/feedback and prototyping work to ensure the work, when completed, will meet the needs of the Industry.
The Simple Storage Management Model (SSM) is designed to make the Storage Management Initiative Specification (SMI-S) more efficient and easy to use, especially for entry-level work.
This document defines a Linear Tape File System (LTFS) Format separate from any implementation on data storage media. Using this format, data is stored in LTFS Volumes. An LTFS Volume holds data files and corresponding metadata to completely describe the directory and file structures stored on the volume.
This paper explores the requirements that High Availability extensions to the NVM.PM.FILE mode of the SNIA NVM Programming Model might place on high speed networking, specifically RDMA.
We propose an approach to digital content preservation that leverages the processes of the archival profession thus helping archivists remain comfortable with the digital domain. One of the major needs to make this strategy possible is a digital equivalent to the physical container - the archival box or file folder - that defines a series, and which can be labeled with standard information in a defined format to allow retrieval when needed. Self-contained Information Retention Format (SIRF) is intended to be that equivalent - a storage container format for a set of (digital) preservation objects that also provides a catalog with metadata related to the entire contents of the container as well as to the individual objects and their interrelationship. This logical container makes it easier and more efficient to provide many of the processes that will be needed to address threats to the digital content.
This Working Draft defines an interface between WBEM-capable clients and servers for the secure, extensible, and interoperable management of networked storage.
This Working Draft describes a standardized method to assess the energy efficiency of commercial storage products in both active and idle states of operation. A taxonomy is defined that classifies storage products in terms of operational profiles and supported features. Test definition and execution rules for measuring the power efficiency of each taxonomy category are described; these include test sequence, test configuration, instrumentation, benchmark driver, IO profiles, measurement interval, and metric stability assessment. Qualitative heuristic tests are defined to verify the existence of several capacity optimization methods. Resulting power efficiency metrics are defined as ratios of idle capacity or active operations during a selected stable measurement interval to the average measured power.
The LTFS Bulk Transfer standard defines a method by which a set of files, directories and objects from a source system can be transferred to a destination system. The bulk transfer of large quantities of data is well suited for LTFS due to the economic and environmental characteristics of tape. Building on top of the LTFS format, a standardized method for transferring data is defined that provides many advantages.
In this test specification document, we define the overall test scope and test specifications for the Storage Network Industry Association (SNIA) to test the conformance to the CDMI specification.
The CDMI Reference Implementation is a SNIA Software development project that implements the Cloud Data Management Interface.
The Cloud Storage Technical Work Group is adding new functionality to CDMI by publishing individual extensions the the CDMI standard. These can be implemented as needed in conjunction with a CDMI implementation to add new functionality before the next release of CDMI. As implementation experience is gained and interoperable implementations are tested, these extensions will be made part of the next release of CDMI.
The Cloud Storage TWG will also be publishing profiles of CDMI that scope it down to specific use cases based on different types of clouds.
See the dedicated web page DRAFT CDMI Extensions and Profiles for additional information.
