Redfish Release 2021.3 Now Available

Posted on Tue, 11/30/2021 - 09:09

DMTF’s Redfish®, Release 2021.3 is now available for public download. Designed to deliver simple and secure management for hybrid IT and the Software Defined Data Center (SDDC), the latest release of the Redfish standard includes three new schemas, 20 schema updates, and additional developer resources. 

The new release includes support for Licenses and License Management allowing for inventory and installation of licenses, as obtained by the end user, or otherwise included in a product implementation. The release supports Service-level, Device-centric or Capacity-limited license types to allow for a variety of licensing models. This support allows for either binary (file-based) or text-based licenses in a unified fashion to provide a single, interoperable method for client software to implement. The 2021.3 release also includes support for electrical buses and related products added to the PowerDistribution schema with added properties to Outlet, Circuit, Chassis, and PowerSupply to show electrical connectivity between devices.

These latest enhancements are driven by the growth of Redfish and interoperability feedback received from implementers. Some of the items in the new Redfish 2021.3 update include:

  • Redfish Specification v1.14.1 – Clarified the link header clause and corrected payload annotation examples.
