Redfish Release 2023.3 Now Available!

Posted on Thu, 01/25/2024 - 09:15

DMTF’s Redfish® Release 2023.3 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 1 new schema and 26 schema updates including a NEW ResolutionStep for providing a recommended step to resolve a condition (fault, error, etc.).

To improve developer access to and synchronization with the latest Redfish releases, a new public GitHub repository has been created to host copies of the published Redfish schemas and standard message registries. The new Redfish-Publications GitHub repository contains the contents of DSP8010 and DSP8011, providing the ability to both download and create durable links to DMTF-maintained materials.

These latest enhancements are driven by the growth of Redfish and interoperability feedback received from implementers. Some of the items in the new Redfish 2023.3 update include:

  • Redfish Specification v1.20.0 – Added requirement for Outbound Connections to include the Sec-WebSocket-Protocol header as “Redfish”; added requirement that services shall accept empty JSON objects for actions that do not have required parameters. 
  • Redfish Specification v1.19.1 (errata release) – Clarified that users can delete their own Session resources; added URI construction guidance for @Redfish.ActionInfo and OEM actions; updated the Members@odata.nextLink clause to give guidance for handling the original query parameters and for using the $skiptoken parameter; clarified the behavior of $expand query option when used with resources containing reference objects; and added ability to configure the support of HTTP Basic authentication.
  • 2023.3 Redfish Schema Bundle – This .zip file contains the current versions of all Redfish schemas. The bundle includes 1 new schema and 26 schema updates and developer resources.
    • NEW ResolutionStep for providing a recommended step to resolve a condition (fault, error, etc.).

  • Redfish Property Guide – Intended primarily for schema authors, this newly reference guide helps with locating existing property definitions within the Redfish schema. Additionally, it helps avoid re-defining property names already in use.
