Redfish Release 2021.2 Now Available

DMTF’s Redfish®, Release 2021.2 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 8 new schemas, 42 schema updates, and additional developer resources. 

The new release includes the OAuth 2.0 Authorization Framework allowing for authorization to be performed by an external entity – no usernames or passwords need to be provided by the client.  Additionally, there are several new additions to the support modeling use cases for SmartNICs including the AllowDenyCollection, which was added to NetworkDeviceFunction to show firewalling configurations; the ProcessorCollection was added to NetworkAdapter to show offload processors dedicated to a SmartNIC; and a DPU Value was added to SystemType in ComputerSystem to showcase a system-view of an SoC on a SmartNIC. Key provisioning via Redfish was also added to support NVMe-oF boot use cases where UEFI and the OS need key information to connect to remote NVMe-oF targets.

These latest enhancements are driven by the growth of Redfish and interoperability feedback received from implementers. Some of the items in the new Redfish 2021.2 update include:

  • Redfish Specification v1.14.0 – Adds OAuth 2.0 as a method of authorization and a new clause describing OEM-defined query parameters.
