Data storage services

The LTFS Format Specification defines a file system 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.
The LTFS Format has these features:
An LTFS Volume can be mounted and volume content accessed with full use of the data without the need to access other information sources.

• Data can be passed between sites and applications using only the information written to an LTFS Volume.
• Files can be written to, and read from, an LTFS Volume using standard POSIX file operations.

The LTFS Format is particularly suited to these usages:

• Data export and import.
• Data interchange and exchange.
• Direct file and partial file recall from sequential access media.
• Archival storage of files using a simplified, self-contained or “self-describing” format on sequential access media.

The Solid State Storage System (S4) TWG was created for the purpose of addressing the unique performance behavior of solid state storage systems. The TWG creates specifications which provide guidance to accurately measure the performance of enterprise arrays as oppose to devices. These specifications are vendor agnostic and support all the solid state storage system technologies of member companies.

The S4 TWG:

• Acts as the primary technical entity for the SNIA to identify, develop, and coordinate system performance standards for solid state storage systems
• Produces a comprehensive set of specifications and drives consistency of measurement guidelines and messages related to solid state storage systems
• Documents system–level requirements and shares these with other performance standards organizations under the guidance of the SNIA Technical Council and in cooperation with the SNIA Strategic Alliances Committee

The Solid State Storage Technical Work Group has been created for the purpose of developing standards related to system implementations of Solid State Storage technology.
The Solid State Storage TWG:

• Acts as the primary technical entity for the SNIA to identify, develop, and coordinate systems standards for Solid State Storage.
• Produces a comprehensive set of specifications and drives consistency of interface standards and messages across the various Solid State Storage related efforts.
• Documents system-level requirements and shares these with other Solid State Storage standards organizations under the guidance of the SNIA Technical Council and in cooperation with the SNIA Strategic Alliances Committee.

The SSM TWG is a technical work group of the SNIA Technical Committee defining the Swordfish specification that extends the Distributed Management Task Force (DMTF)'s Redfish specification (API) to handle the emanagement of storage equipment and storage services found in modern data centers.

The target market for this interface is Cloud and Web-based IT professionals for scalable storage management and related data services. Within this community, the focus is on usability by non-computing science degree personnel. The interface should be simple to use, accessible, and compatible with the existing tool chains and with modern transports.

Recommendation ITU-T F.743.2 defines the cloud storage service requirements in visual surveillance. Cloud storage enables service users to have ubiquitous, convenient, on-demand network access to a shared pool of configurable storage resources, which can be rapidly provisioned and released with minimal management effort or service-provider interaction. Cloud storage can realize flexible and reliable data storage for large-scale visual surveillance, and its components are modularized and allocated dynamically based on real usage. This Recommendation provides the application scenarios and requirements for cloud storage in visual surveillance.

Recommendation ITU-T H.626.2 defines a cloud storage architecture in visual surveillance. Cloud storage enables the service users to have ubiquitous, convenient and on-demand network access to a shared pool of the configurable storage resources, which can be rapidly provisioned and released with the minimal management effort or service-provider interaction. Cloud storage can realize flexible and reliable data storage for large-scale visual surveillance and its components are modularized and allocated dynamically based on the real usage. This Recommendation provides the architecture, entities, reference points and service control flow for cloud storage in visual surveillance.

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.

Standards for data management within and among local and distributed information systems environments. SC 32 provides enabling technologies to promote harmonization of data management facilities across sector-specific areas. Specifically, SC 32 standards include:

• reference models and frameworks for the coordination of existing and emerging standards;
• definition of data domains, data types, and data structures, and their associated semantics;
• languages, services, and protocols for persistent storage, concurrent access, concurrent update, and interchange of data;
• methods, languages, services, and protocols to structure, organize, and register metadata and other information resources associated with sharing and interoperability, including electronic commerce.

SC 31 continues to deliver technically rigorous standards that meet user requirements. Looking ahead in 2016 SC31 will deliver three standards of note. One jointly developed with SC 17 will measure the quality of OCR Characters used on passports significantly improving the readability of the characters (ISO/IEC 30116). The second will establish the first quantitative method for test and evaluation of localization systems aiding the first responder community and public safety (ISO/IEC 18305). The third is a method for uniquely identifying devices and items touching the Internet of Things (ISO/IEC 29161). In 2016 SC31 will commence a joint effort with the ISO Conformance Assessment Organization (CASCO) focusing on use of an “eLabel” to replace traditional conformance markings on electronic devices.

This Recommendation provides overview and functional requirements of data storage federation. Data storage federation provides a single virtual volume from multiple data sources in heterogeneous storages. In this Recommendation, configuration for logical components, and ecosystem of data storage federation as well as cloud computing based data storage federation are introduced for data storage federation. Functional requirements are derived from use cases.
