Redfish Release 2025.2 Now Available

Posted on Wed, 06/18/2025 - 09:13

DMTF’s Redfish®, Release 2025.2 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 eight new schemas, 36 schema updates, and a new message registry to support Industrial IoT equipment.

This release is the result of collaboration with several alliance partners, including PCI Industrial Computer Manufacturers Group (PICMG), Open Compute Project (OCP), and the CXL Consortium, who provided invaluable subject matter expertise to further extend the Redfish data model. 

Key highlights of the Redfish 2025.2 release are the additions of:

  • NEW support for Industrial IoT factory automation and job scheduling.  Working in collaboration with PICMG, this release includes several new schemas and other significant extensions to the Redfish data model.
    • NEW AutomationNode and AutomationInstrumentation - Schemas that model Industrial IoT equipment to support monitoring and control of automated factory processes. Includes support for PID-based control loops and single or multi-axis motion controllers. Defines several Actions to control the operating state of each node.
    • NEW JobDocument - Schema defines reusable processes and execution steps for an automated factory, and describes the required or optional parameters for creating specific instances of those jobs
    • NEW JobExecutor - Describes a resource, typically a factory production line, capable of running jobs of a specific type
    • UPDATED JobService and Job – New extensions to instantiate and manage the flow of jobs produced from a reuseable job document
  • NEW VirtualCXLSwitch, and VirtualPCI2PCIBridge schemas, developed in conjunction with the CXL Consortium, add support for Virtual CXL Switch and Virtual PCI-to-PCI Bridge devices
  • NEW UpdateServiceCapabilities schema and enhancements to UpdateService to support staging of mass firmware updates. Building on feedback from Open Compute Project (OCP) members, these enhancements allow for “staging” firmware updates, which allows synchronized activation of new images for fleet-level updates.
  • NEW TelemetryData – Provides a mechanism to retrieve device-specific telemetry data in bulk from a device without requiring the manager (BMC) to decode or unpack data intended for consumption by a specific client application

These latest enhancements are driven by the growth of Redfish and interoperability feedback received from implementers. Some of the items in the Redfish 2025.2 update include:

  • Redfish Specification v1.22.1
    • ETag guidance to avoid unnecessarily frequent updates
    • Corrected ST header for SSDP to align with UPnP
    • Message guidance for @Message.ExtendedInfo in response to PUT or PATCH operations
  • 2025.2 Redfish Schema Bundle – This .zip file contains the current versions of all Redfish schemas. In addition to the eight new schemas, this release bundle includes 36 schema updates, along with developer resources.
    • Extended UpdateService and SoftwareInventory to support staging and bulk activation of firmware images
    • Extended Job to support job creation from reusable job documents
    • Added Modbus support to AggregationSource, ConnectionMethod, ManagerNetworkProtocol, and SerialInterface supporting aggregation of data from Modbus Serial or Modbus TCP devices
    • Addition of ConditionType to the common Status object providing means to trace the source of individual Condition or Health values to the affected subsystem or resources instance
  • Redfish Message Registry Bundle 2025.2 – The Message Registry Bundle (DSP8011) contains all released Redfish message registries.
    • NEW AutomationNodeEvent message registry supports Industrial IoT automation node equipment
    • Environmental v1.2.0 adds thermal subsystem messages for liquid cooling equipment
    • JobEvent v1.1.0 adds messages related to job validation outcomes
    • Platform v1.3.0 adds messages for PCIe, memory, power, and device fault conditions
    • StorageDevice v1.5.0 adds messages for volume re-building or re-configuring
    • Telemetry v1.1.0 adds TelemetryDataCreated message
    • Update v1.2.0 adds messages for updates skipped or not applicable
  • Redfish Release 2025.2 Overview – This presentation provides detailed descriptions of each revision in Redfish 2025.2.
  • Redfish Resource and Schema Guide – Updated for 2025.2 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 Conformance Testing Tools - Open source tools for service developers to validate their conformance with the Redfish protocol, data model, and profiles. Tools include the Redfish Protocol Validator, Redfish Service Validator, Redfish Interop Validator.
  • Redfish Publications Repository - Public GitHub repository contains an official read-only copy of the Redfish schemas and standard message registries
    • Creates public, durable locations for referencing specific schema or registry items in issue reports, forum postings, or other online references
    • Allows developers to automatically synchronize with new Redfish releases using normal GitHub tools and processes
    • Repository will be updated as each Redfish release become public
  • Redfish Data Model Specification – Includes normative statements (“LongDescription”) and informative description details from schema in a single document. Intended for both Redfish Service and client-side developers.
  • 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.
