nVent Releases Next Generation nVent SCHROFF MicroTCA.4 Crate

  • NEW MTCA.4 Crate achieves 128 Gbits bandwidth per slot with PCIe Gen 5
  • Enhanced Cooling: Improved rear card cage cooling
  • Future Proof: New Cooling Unit Manager design based on controller with long life cycle
  • Backward Compatible: Mix and match legacy and new chassis and cooling units

nVent Electric plc (NYSE:NVT) (“nVent”), a global leader in electrical connection and protection solutions, announced the launch of its first MicroTCA.4 (MTCA.4) Crate in accordance with Revision 3.0 of the MTCA.0 base standard.

In September 2023 PICMG released Revision 3.0 of the MTCA.0 specification. This revision supports PCI Express Gen 4 and PCI Express Gen 5, as well as 100GBASE-KR4, to improve system performance by 4x. To accomplish these higher data rates, SMD and compression mount connectors have been evaluated by the Next-Gen MTCA working group, and the simulation results have been taken as a base to define the whole data transmission channel for MicroTCA. The transmission channel has been divided into logical parts to define the limits for boards and backplane to ensure all MTCA.0 Rev 3.0 MCHs, AMCs and crates work together in a PCI Express Gen 4/5 or 100 GbE environment.

As these high-end switches consume more power compared to their predecessors, the power budget for the MicroTCA Carrier Hub (MCH), where the switch resides, has been upgraded from 80 W to 110 W. To prevent overheating, the cooling unit’s power budget was also upgraded to 110 W. A software mechanism helps ensure the backward compatibility of old and new MCHs, Power Modules and Cooling Units.

In the Rear Transition Module (RTM), cooling the improved 110W power limit is achieved with powerful fans and superior cooling design.

The Cooling Unit firmware performs in accordance with revision 3.0 of the MicroTCA specification. When powering up it remains in the 80 W power rating. If the Power Module supports 110 W per slot, the cooling unit will adjust accordingly. If it only supports 80 W, or if the IPMI communication gets lost, the Power Module will stay in the 80W power envelope.

The Renesas H8S controller previously used on nVent SCHROFF MTCA.4 Crates has been end of life’d (EOL’d). For this reason, nVent has introduced a new Cooling Unit Manager design based on the STM32 controller from STMicroelectronics, which includes the additional features described above.

Providing the Highest Data Bandwidth

To achieve the higher data bandwidth, the maximum trace length defined in the MTCA.0 Rev. 3.0 specification needs to be matched. Therefore, MCH slots were moved from the outside to the middle of the card cage.

Upgraded Materials

The PCB material has been upgraded to a lower loss material with SMD connectors for superior performance. For optimized routing, the physical order of the AMC modules has been changed. In the past, nVent SCHROFF MTCA.4 Crates used the physical order starting from 1 (from left to right), which has now changed to: 7-8-9-10-11-12-MCH1-MCH2-6-5-4-3-2-1.

30 Years of Advancing Open Standards in Embedded Computing

Jess Isquith

As PICMG’s 30th anniversary comes to a close, it’s worth reflecting on the incredible progress and momentum built over the past three decades. Today, we are a vibrant, diverse community of engineers and innovators with member companies from more than 20 countries. These organizations are responsible for expanding PICMG’s global influence, as well as the sustained adoption of PICMG specifications and products in key growth areas.

These growth areas include:

* IoT Expansion
* Edge Computing
* Automation and AI
* Security

The ongoing adoption of open standards is driven by the same core principles that have guided PICMG for three decades: flexibility, vendor-neutral competition (no lock-in), long lifecycle support, and security. We’re proud to support open standards in an embedded computing industry that is forecast to exceed $150 billion USD by 2030—where open standards alone represent about 30% of the market and hardware accounts for a significant portion of that $50 billion.

While we celebrate our successes, we also recognize that many of the early pioneers and members of PICMG are transitioning to new phases in their careers. We thank them for their invaluable contributions and have full confidence that the next generation of engineers will continue to carry forward their legacy of excellence and innovation.

Looking ahead, PICMG remains open to new members. We encourage organizations and companies to get involved, learn more about our work, and explore the many opportunities available to contribute to the future of embedded computing. Visit picmg.org or reach out to me directly at [email protected].

We’re excited for the next chapter in the PICMG journey.

DMTF Publishes PICMG IoT.x IP Submission into Redfish API Specification

PICMG

  • PICMG IoT.1 interoperable data modeling capabilities have been included in the latest release of the DMTF Redfish specification.
  • Ongoing work will extend the Redfish job model to support factory orchestration and management via cloud-based platforms like AWS.
  • A reference Redfish server based on PICMG IoT.x is being developed on GitHub to demonstrate the potential of plug-and-play Industry 4.0 use cases.

WAKEFIELD, MA. PICMG, the consortium driving open standards for modular, scalable computing, and DMTF, have announced that an IP submission containing the PICMG IoT.x firmware specification was accepted and included in the most recent Work in Progress phase of the Redfish® standard. The extensions to Redfish will streamline the creation of plug-and-play Industry 4.0 systems by connecting interoperable data models on IoT.x-enabled endpoints to software-defined converged infrastructure via the Redfish API.

Redfish is an IT industry standard commonly used for data collection and device management in equipment such as data center fans and coolant pumps. Since 2018, PICMG and DMTF have worked collaboratively to extend the capabilities of Redfish to automation and factory equipment, enabling remote management and control of robotic motion platforms, contextualized sensing systems, and other advanced control endpoints.

The result of those efforts is PICMG IoT.1 and IoT.2, which add extensions to DMTF’s Redfish standard, now included in the latest publication.

“DMTF specifies protocols, data formats, and models for interoperable management on control plane infrastructure including edge systems,” said Jeff Hilland, DMTF president. “Since a lot of what we do is applicable to edge hardware, it makes sense to work with PICMG as part of our alliance partner program.”

Extending Data and Control Capabilities

The PICMG IoT.1 firmware specification defines a standard data model for sensor makers and systems integrators, while PICMG IoT.2 addresses the data model and network architecture requirements for the integration of larger sensor/effector networks.

Together, the two specifications accelerate the development and deployment of smart sensors in Industry 4.0 applications. Redfish extensions integrate these capabilities in a larger system of systems context while remaining fully compatible with the PICMG IoT.x specifications.

PICMG is also working on extending the Redfish job model to support cloud-based scheduling and orchestration of factory equipment. This will allow industrial operators to leverage powerful cloud platforms like AWS to manage jobs all the way to control endpoints on a factory floor.

“Imagine a modular factory where every component is interconnected and fully plug-and-play not just at the sensor and effector level, but across the entire assembly line,” said Doug Sandy, CTO of PICMG. “A factory where every piece of equipment has its own associated Redfish service, workloads, and processing could happen wherever they need to, while operators could manage and monitor everything through a top-down hierarchy of building, floor, and line controllers.”

“That’s what PICMG and DMTF ultimately want to support. And with our current work on Redfish, we’ve taken a big step in the right direction,” he added.

Building the Factory of the Future

PICMG’s IP submission recently entered DMTF’s Work in Progress phase and is slated for a projected full release in 2025. During the Work in Progress phase, the development community will have the opportunity to review and comment on the new content of the specification so changes can be incorporated prior to the next Redfish release.

PICMG and DMTF also currently have a team working on an example implementation of the interoperable data environment, expressed in the form of an open-source server. Accessible on the PICMG GitHub repository, new functionality is being added to the server each month with the goal of it becoming fully functional in time for the next Redfish specification release.

The PICMG extension is publicly available on the DMTF website at: www.dmtf.org/sites/default/files/PICMG_DMTF_Work_Register_v1.1.pdf.
