DMTF’s Redfish^®, Release 2021.4 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 four new schemas, 29 schema updates, and additional developer resources. 

Key highlights of the Redfish 2021.4 release are the addition of ComponentIntegrity, RegisteredClient, and ServiceConditions schemas. The new Component Integrity Model allows resources to represent security related information between two entities (typically a BMC and end device); the RegisteredClient resource collection enables clients to be aware of other clients to avoid configuration conflicts when desired; and the ServiceConditions resource provides a roll up of all active, non-normal status conditions that require attention. 

These latest enhancements are driven by the growth of Redfish and interoperability feedback received from implementers. Some of the items in the new Redfish 2021.4 update include:

• Redfish Specification v1.15.0 – Updated Operation apply time and Multipart HTTP operations to expand usage of OperationApplyTimeSupport
• 2021.4 Redfish Schema Bundle – This .zip file contains the current versions of all Redfish schemas. The bundle includes four new schemas, 29 schema updates and additional developer resources. 
  • Addition of ComponentIntegrity, ManagerDiagnosticData, RegisteredClient and ServiceCondition schemas
• Redfish Message Registry Bundle 2021.4 – The Message Registry Bundle (DSP8011) contains all released Redfish message registries.

• Redfish Release 2021.4 Overview – This presentation provides detailed descriptions of each revision in Redfish 2021.4.
• Redfish Resource and Schema Guide – Updated for 2021.4 this human-readable guide to the Redfish Schema is designed to help educate users of Redfish. Application developers and DevOps personnel creating client-side software to communicate with a Redfish service, as well as other consumers of the standard, will benefit from the explanations in this resource. 
• Redfish Property Guide – Intended primarily for schema authors, this newly revised reference helps with locating existing property definitions within the Redfish schema. 
• Redfish Release History – Updated with each new release, this presentation offers a comprehensive view of each revision to Redfish since 2016.
