Technical Work Groups
SNIA's Technical Work Groups (TWGs) deliver information and standards that accelerate the adoption of storage networking. They support the SNIA mission, charting a course for the storage industry. If you are thinking about becoming a member of the SNIA, check out what our TWGs are doing. Benefits of joining a Technical Work Group include:
- Make sure the next revision of the standard meets the technical requirements of your company.
- Gain in-depth knowledge of the details in the standard being developed and as a result, become an expert on the standard.
- Fastest way to become an Expert is through participation, not just reading the standard!
- Work with and get assistance from the other experts on the standard as you develop your implementation of the standard.
- Participate in the development and become an expert in the Software being developed in support of the standard.

Cloud Storage TWG
The Cloud Storage TWG acts as the primary technical entity for the SNIA to identify, develop, and coordinate systems standards for Cloud Storage. This group aims to produce a comprehensive set of specifications and drives consistency of interface standards and messages across the various Cloud Storage related efforts. The TWG also 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. SNIA members can join the TWG here. Not a SNIA member yet? Join now.
Green Storage TWG
The Green Storage TWG acts as the primary technical entity for the SNIA to identify, develop, and coordinate technical matters related to energy and cooling of storage networking products. To be effective, standard metrics must be a realistic reflection of efficiency: work accomplished per energy expended, allowing a determination of clear costs for operations. We believe that a variety of types of storage work must be considered, and that several distinct 'figures of merit' will be needed. We believe that the SNIA is uniquely qualified, as an impartial forum with the right participants, to create useful metrics for users.
I/O Traces, Tools & Analysis TWG
The primary focus of the I/O Traces, Tools, and Analysis (IOTTA) TWG is to create a worldwide repository for storage-related I/O trace collection and analysis tools, application workloads, I/O traces, and best practices around such topics. That repository is located at http://iotta.snia.org
The I/O traces of interest to the IOTTA TWG include those up at the host (e.g., system call, file system), those involving a file server (e.g., NFS, CIFS) and those at the "transport level" (e.g., SCSI, Fibre Channel). I/O traces of application workloads along with the analysis and definition of common, recommended semantics and formats for I/O traces are also specific areas of focus for the TWG. Standardized I/O trace formats/semantics will enable the development and use of common I/O trace collection and analysis tools as well as facilitate the sharing of the I/O traces themselves.
The IOTTA TWG is for those interested in the use of empirical data/metrics to better understand the actual operation and performance characteristics of storage I/O, especially as they pertain to application workloads. This includes not only storage vendors but also storage users as well as those within the academic community who are performing research related to storage I/O and storage devices.
Linear Tape File System (LTFS) TWG
The Linear Tape File System TWG was created for the purpose of developing SNIA Architecture related to the on-tape format for LTFS.
Long Term Retention TWG
The Long Term Retention (LTR) TWG is focused on the technical challenges of long term digital information retention & preservation, namely both physical ("bit") and logical preservation.
The TWG will generate reference architectures, create new technical definitions for formats, interfaces and services, and author educational materials. The group will be working to ensure that digital information can be efficiently and effectively preserved for many decades, even when devices are constantly being replaced, new technologies, applications and formats are introduced, consumers (designated communities) often change, and so on.
NVM Programming TWG
The NVM Programming TWG was created for the purpose of accelerating availability of software enabling NVM (Non-Volatile Memory) hardware. The TWG creates specifications which provide guidance to operating system, device driver, and application developers. These specifications are vendor agnostic and support all the NVM technologies of member companies.
Object Drive TWG
- Acts as the primary technical entity for the SNIA to identify, develop, and coordinate standards for Object Drives operating as storage nodes in scale out storage solutions.
- Produces a comprehensive set of specifications related to data and control path interfaces and protocols.
- Promotes interoperability among Object Drive software hosting environments
Scalable Storage Management (SSM) TWG
The SSM TWG is a technical work group of the SNIA Technical Committee, intending to create a specification that defines a customer centric interface for the purpose of managing storage and related data services.
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.
The DMTF Scalable Platforms Management Forum (SPMF) creates management specifications for the adjacent server management domain. The SSM TWG collaborates with the DMTF SPMF to align interfaces to enable a seamless, holistic storage system management experience, with goals to:
- Create an HTTP/HTTPS RESTful interface using the Redfish protocol and schema
- Produce an extensible interface with sufficient compatibility rules
- Enable delivery of value-add, vendor-specific data alongside standardized items
The Security TWG provides architectures and frameworks for the establishment of information security capabilities within the storage networking industry, including that of stored information in heterogeneous environments. The focus of the Security Work Group is directed toward long-term security solutions, taking into account any security inherent in underlying transports or technologies.
The Storage Management Initiative Technical Work Group (SMI TWG) is responsible for the maintenance and evolution of the SNIA Storage Management Initiative Specification (SMI-S). SMI-S defines an interface for the interoperable management of a heterogeneous Storage Area Network (SAN). It describes the information available to a WBEM Client from an SMI-S compliant CIM Server via an object-oriented, XML-based, messaging-based interface designed to support the specific requirements of managing devices in and through SANs.
Solid State Storage TWG
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.
Solid State Storage System TWG
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
- Produce 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
One objective of this TWG is communicating the need for accurately measuring the performance of solid state storage systems and its unique behavior. By aggregating the goals of SNIA members, we hope to get solid state storage array vendors in agreement on how to accurately measure performance of this technology. This is expected to accelerate the availability of a broad range of solid state storage array solutions to customers.
