SNIA develops a wide range of standards to enhance the interoperability of various storage systems.
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.
The Common RAID Disk Data Format specification defines a standard data structure describing how data is formatted across the disks in a RAID group. The Disk Data Format (DDF) structure allows a basic level of interoperability between different suppliers of RAID technology. The Common RAID DDF structure benefits storage users by enabling data-in-place migration among systems from different vendors.
The iSCSI Management API defines a standard interface that applications can use to perform iSCSI management independent of the vendor of the iSCSI HBA. The IMA was designed to be implemented using a combination of a library and plugins.
An IMA library provides the interface that applications use to perform iSCSI management. Among other things, the library is responsible for loading plugins and dispatching requests from a management application to the appropriate plugin(s). Plugins are provided by iSCSI HBA vendors to manage their hardware. Typically, a plugin will take a request in the generic format provided by the library and then translate that request into a vendor specific format and forward the request onto the vendor’s device driver. In practice, a plugin may use a DLL or shared object library to communicate with the device driver. Also, it may communicate with multiple device drivers. Ultimately, the method a plugin uses to accomplish its work is entirely vendor specific.
The Multipath Management API allows a management application to discover the multipath devices on the current system and to discover the associated local and device ports. An implementation of the API may optionally include active management (failover, load balancing, manual path overrides). The API uses an architecture that allows multiple MP drivers installed on a system to each provide plugins to a common library. The plugins can support multipath drivers bundled with an OS, or drivers associated with an HBA, target device, or volume manager. This API can be used by host-based management applications and will also be included in the SMI-S Host Discovered Resources Profile for enterprise-wide multipath discovery and management. A client of the API should be able to move between platforms by simply recompiling.
The purpose of the SNIA Emerald™ Power Efficiency Measurement Specification is to provide a reproducible and standardized assessment of the energy efficiency of commercial storage products in both active and idle states.
The Storage Management Initiative Specification defines a method for the interoperable management of heterogeneous networked storage.
The XAM Interface specification defines a standard access method (API) between "Consumers" (application and management software) and "Providers" (storage systems) to manage fixed content reference information storage services. XAM includes metadata definitions to accompany data to achieve application interoperability, storage transparency, and automation for ILM-based practices, long term records retention, and information security. XAM will be expanded over time to include other data types as well as support additional implementations based on the XAM API to XAM conformant storage systems.
