DMTF and PICMG Form Alliance
DMTF and the PCI Industrial Computer Manufacturer Group (PICMG) have formed an alliance to help ensure the two organizations’ standards are coordinated and aligned in the Industrial Internet of Things (IIoT) domain.
Expect to see Redfish listed as 10th entry here shortly, I am guessing:
ISO/IEC 30115:2018: The Redfish Scalable Platforms Management API (“Redfish”) is a new specification that uses RESTful interface semantics to access data defined in model format to perform out-of-band systems management. It is suitable for a wide range of servers, from stand-alone servers to rack mount and bladed environments but scales equally well for large scale cloud environments. There are several out-of-band systems management standards (defacto and de jour) available in the industry. They all either vary widely in implementation, were developed for single server embedded environments or have their roots in antiquated software modeling constructs. There is no single industry standard that is simple to use, based on emerging programming standards, embedded friendly and capable of meeting large scale data center & cloud needs.
The DMTF has released its new Platform Level Data Model (PLDM) for Redfish® Device Enablement Specification  as a Work in Progress, inviting public review and comment. This standard enables a management controller to present Redfish -conformant management of I/O adapters in a server, without the need for code specific to each adapter family/vendor/model. PLDM for Redfish Device Enablement describes the operation and format of request messages (also referred to as commands) and response messages, designed to be delivered using PLDM messaging. Using Redfish, messages are generated by a Redfish client through interactions with a user or a script, and communicated via JSON over HTTP or HTTPS to a management controller. Using the new standard, the management controller will encode the message into a binary format (Binary Encoded JSON, or BEJ) and communicate it using PLDM to an appropriate device for servicing. The device processes the message and returns the response back using PLDM to the management controller, again in binary format. The management controller then decodes the response and constructs a standard Redfish response in JSON over HTTP or HTTPS for delivery back to the client. PLDM for Redfish Device Enablement is developed by the DMTF’s Platform Management Components Intercommunications (PMCI) Working Group , which defines standards to address “inside the box” communication and functional interfaces. It can be used in conjunction with other PMCI standards, such as the PLDM Firmware Update Specification, to provide a comprehensive, common architecture for improved communication between management subsystem components. The new WIP release is the latest example of the ongoing hard work and close collaboration between DMTF Working Groups (including PMCI, SMBIOS and SPMF) to seamlessly address both internal- and external-facing interfaces and protocols for system management.
Redfish Specification v1.4.0 is released.
DMTF’s Redfish Version 2017.3 is now available. Version 2017.3 adds new schemas for BootOption, Assembly, Protocol, and more.
[…]Version 2017.2 of the Redfish Schema and version 1.3.0 of the Redfish Specification are now available for public download. The goal of Redfish is to publish a standard API to meet customer demands for simple and secure management in modern Software Defined Data Center (SDDC) environments, and it was recently announced the standard is being expanded to address Data Center Infrastructure Management (DCIM), as well. The latest release includes updates to the Base Message Registry and more.[…]
Note to DMTF PR team: please stop inserting “(http://www.dmtf.org/standards/redfish)” URL after every use of “Redfish”, half a dozen times per paragraph is more than enough.
DMTF has a new educational video series for Redfish in Chinese available:
If you are looking for code that uses the DMTF Redfish or SMBIOS or CIM standardss, DMTF just created a new list of these projects. It looks like there are multiple new Redfish projects these days.
New Redfish Update Adds Composability Support
Continuing its aggressive development timeline, an important update to the DMTF’s Redfish® standard is now available. The newly-released version 2017.1 of the Redfish Schema and version 1.2.0 of the Redfish Specification contain a number of additions, including support for composable infrastructures. With the ultimate goal of addressing all of the components in the data center with a consistent API, Redfish is an open industry standard that helps enable simple, modern and secure management of scalable platform hardware. DMTF continues to expand Redfish to cover customer use cases and technology, and the new Composition Service provides support for binding resources together into logical constructs. For example, disaggregated hardware – which allows for independent components, such as processors, memory, I/O controllers, and drives, to be bound together to create a composed Computer System – becomes a Computer System from an end user perspective in Redfish. Redfish composability allows clients to adjust their hardware configurations in response to their application needs, without having to touch any hardware.
DMTF Releases Updated MCTP SMBus/I2C Transport Binding Specification
The DMTF’s Platform Management Components Intercommunication (PMCI) Working Group defines standards to address “inside the box” communication and functional interfaces between the components of the platform management subsystem (e.g., management controllers, managed devices, etc.). PMCI’s Management Component Transport Protocol (MCTP) over SMBus/I2C Transport Binding Specification is now available in version 1.1.0 . This specification addresses how MCTP packets are delivered over a physical SMBus or I2C medium using SMBus transactions. It defines how physical addresses are used, how fixed addresses are accommodated, how physical address assignment is accomplished for hot-plug or other devices that require dynamic physical address assignment, and how MCTP support is discovered. In addition, timing specifications for bus and MCTP control operations are included, and a “fairness” protocol is defined for the purpose of avoiding deadlock and starvation/lockout situations among MCTP endpoints. The binding has been designed to be able to share the same bus as devices communicating using earlier SMBus/I2C management protocols, such as Alert Standard Format (ASF) and Intelligent Platform Management (IPMI), and with vendor-specific devices using SMBus/I2C protocols. The specification also allows a given device to incorporate non-MCTP SMBus functions alongside MCTP.
As William points out, the DMTF updated SMBIOS, and the Tianocore project updated EDK2 appropriately.
DMTF has just released version 2.0 of the Conformance Test Suite (CTS) for its Desktop and mobile Architecture for System Hardware (DASH) standard. DASH provides secure out-of-band and remote management of desktop and mobile systems. The DASH CTS serves to improve interoperability by validating conforming implementations. The new DASH CTS 2.0 includes the necessary updates, policies and procedures to test the latest DASH specifications, which address current requirements for managing modern hardware in a networked environment. With DASH CTS 2.0, companies can continue to self-test their implementations and submit digitally signed results to the DASH Conformance Program Administrator (an independent third party) for validation. Once validated, participants can have their submission information included in the DMTF Certification Registry.[…]
Quoting their press release:
“DMTF’s innovative Redfish standard continues its fast progression, thanks to the dedicated efforts of the Scalable Platforms Management Forum (SPMF). To date, Redfish has focused on defining a TCP/IP-based out-of-band interface between a client and a management controller. Today, the newly available Redfish Host Interface Specification expands these capabilities to allow applications and tools running on an Operating System – including in the pre-boot (firmware) stage – to communicate with the Redfish management service. Every device exposes an interface to the host software (Operating System or Hypervisor). Management controllers are no different, and this standard modernizes this interface to equalize the capabilities of “in-band” or “host-based” applications with remote applications using Redfish. To learn more about Redfish or to download the Redfish Host Interface specification, please the Redfish web site. Developers can also visit the Redfish Developer Hub, a one-stop, in-depth technical resource with all the files, tools, community support and education you may need to help you use Redfish. To participate in the Host Interface Task Force, please join the DMTF’s SPMF.”
“New in Version 3.1, SMBIOS now includes support for mini PCIe and Trusted Platform Module (TPM) devices, and adds new chassis types for Internet of Things (IoT) gateways, as well as embedded, mini and stick PCs. In addition, the standard has been updated to support extended BIOS ROM size and cache sizes greater than 2047 MB.[…]”
Apparently Lenovo’s XClarity Administrator software uses the Redfish API:
“Lenovo XClarity is a fast, flexible, and scalable hardware systems management application that enables administrators to deploy infrastructure faster and with less effort. This video provides a brief overview of XClarity Administrator, VMware Integration, the XClarity Mobile App, and new features supporting extended management of storage and network switches.”
Here’s a Lenovo video showing the tech:
The DMTF has a Github project for DMTF. They’ve recently updated it to include new tools, including ‘redfishtool’. Quoting their press release:
New tools recently shared include:
* Redfish Service Validator – a Python 2.7 tool for checking conformance of any “device” with a Redfish service interface against a Redfish CSDL schema.
* Redfish Profile Simulator – a Flask-based real simulator of the initial OCP Feature profile. Resources are loaded from a mockup into Python dictionary structures.
* Redfishtool CLI tool – a Python 3.4 program that implements a commandline tool for accessing the Redfish API. The tool outputs Redfish JSON responses for common use cases, and shows the proper way to implement the hypermedia aspects of the Redfish API.
* Mockup Creator – a Python 3.4 program that creates a Redfish Mockup folder structure from a real live Redfish service. The program executes Redfish GET requests to the Redfish service and saves the response in a file structure.
These new items join additional tools currently available in the GitHub repo:
* CSDL to JSON-schema converter – converts a valid Redfish CSDL schema to the JSON-schema (draft v4) format.
* OData CSDL Validator – a Python 3.0 tool that crawls through OData-formatted metadata, parses it and validates that it conforms to OData V4.0.
* Mockup Server – a simple Python 3.4 program that can be copied into a folder at the top of any Redfish mockup and serve Redfish requests on the specified IP/port.
* Documentation Generator – a utility to format text and values extracted from the Redfish JSON-schema files and incorporate text from additional Markdown documents to generate either web-based (Slate) or easily printed (converted to PDF) end-user documentation of the Redfish schema.

WMI, the Windows-centric API wrapper the DMTF CIM standard, has an OMI variant that works outside of Windows. I don’t understand why Microsoft didn’t just submit OMI to DMTF, instead of OpenGroup… 🙂
Open Management Infrastructure (OMI) is an open source project to further the development of a production quality implementation of the DMTF CIM/WBEM standards. The OMI CIMOM is also designed to be portable and highly modular. In order to attain its small footprint, it is coded in C, which also makes it a much more viable CIM Object Manager for embedded systems and other infrastructure components that have memory constraints for their management processor. OMI is also designed to be inherently portable. It builds and runs today on most UNIX® systems and Linux. In addition to OMI’s small footprint, it also demonstrates very high performance. RPM and DEB packages are provided for the installation of OMI on most enterprise Linux distributions. To install OMI, download the correct package for your Linux computer. […]
