DMTF’s Redfish^®, Release 2022.3 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 40 schema updates and 3 new schemas including CXLLogicalDevice, Heater, and HeaterMetrics. 

Key highlight of the Redfish 2022.3 release is the addition of support for CXL devices and fabrics, defined by DMTF alliance partner Compute Express Link (CXL) Consortium. The Fabric and Device data models have been extended to incorporate CXL Device Types 1,2, and 3. Other additions include support for multi-factor authentication, and support for heaters inside a chassis with new Heater and HeaterMetrics resources.

These latest enhancements are driven by the growth of Redfish and interoperability feedback received from implementers. Some of the items in the new Redfish 2022.3 update include:

• Redfish Specification v1.17.0 (NEW ADDITIONS) – Adds support for multi-factor and client certificate-based authentication. Enhanced schema annotations support URI deprecation and write-only properties and adds optional support for HTTP 2.0.
