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.
Work-in-Progress DRAFTS are subject to change. The Work-in-Progress DRAFT  may be updated, replaced, or made obsolete at any time. Some of the Intellectual Property protections for users of SNIA software and specifications are not applicable to users of Work-in-Progress DRAFTs.

Cloud Data Management Interface (CDMI) v1.0g DRAFT

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.

Hypervisor Storage Interfaces for Storage Optimization White Paper DRAFT rev 0.5a

This paper is aimed at Hypervisor software providers and providers of storage intended for use with Hypervisor environments. It documents best practices for using copy offload and space reclamation technology in a blocks environment. This includes using the SCSI Extended Copy command for providing copy offload services and SCSI UNMAP operations for space reclamation services.

Cloud Storage Reference Model v0.3 Trial-Use Draft

This paper sets out a model of cloud storage elements that describes a logical view of their functions and capabilities using a descriptive taxonomy. The purpose of this model is to form a basis upon which industry efforts can be organized, needed standards identified and vendor products can be described by vendor independent terminology. In addition, this model is used to describe standard interfaces for cloud storage.

Green Storage Power Measurement Technical Specification v0.0.18 DRAFT

The initial draft Green Storage Power Measurement Specification defines a baseline standard for idle power metrics which can be applied as a uniform method for collecting idle power consumption measurements.  It also includes a “Green Storage Taxonomy” for classifying storage products based on energy consumption characteristics and application environments.

Common Trace Semantics Specification v1.0 rev 9 DRAFT

The Common Trace Semantics Specification defines common, recommended semantics for data in I/O traces. Standardized I/O trace 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.
