DMTF’s Redfish^®, Release 2023.1 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 28 schema updates and 11 new schemas as well as additional query parameters added to the syntax of the Redpath Specification.

The key highlights of the Redfish 2023.1 release are support for Cooling Distribution Units and CoolingLoops, including critical subsystems such as LeakDetectors, Pumps, Reservoirs, and Filters. Also included are enhancements to the Drive and Storage models with new DriveMetrics and StorageControllerMetrics resources and StorageController actions. Other additions include new standard message registries to define messages for common events or errors related to Platform, Power, and Environmental conditions.

These latest enhancements are driven by the growth of Redfish and interoperability feedback received from implementers. Some of the items in the new Redfish 2023.1 update include:

• Redfish Specification v1.18.0 – Adds URI segment annotation clause to allow schemas to describe URIs that do not match applicable naming rules
• Redfish Specification v1.17.1 – Errata release. Improved M-SEARCH example response; updated authentication requirements to state that services can optionally reject requests to unauthenticated resources if the provided credentials are invalid; updated Action responses to provide guidance for finding the schema definition of the action response; and updated Response headers to make Access-Control-Allow-Origin an optional response header.
