PICMG releases Platform Management Interface specification for COM-HPC

Wakefield, MA., USA / August, 2021 – PICMG, a leading consortium for developing open embedded computing specifications, announces the release of the COM-HPC Platform Management Interface (PMI) specification. It provides a framework of remote and out-of-band platform management features for COM-HPC Computer-on-Module based edge computing designs and is freely available on the PICMG website. COM-HPC is an open Computer-On-Module (COM) form factor standard for High-Performance Computing (HPC) that combines high-end I/O bandwidth with edge computing performance levels. Standard COM-HPC modules plug into an application-specific carrier board (aka baseboard) and offer OEMs an application-ready computing core to accelerate design cycles, reduce NRE costs and increase ROI as well as sustainability by extending longevity options beyond a certain processor family or module vendor.

 “The dedicated modular system management interface, which gives remote management access to embedded systems – even out-of-band – is another industry first introduced by COM-HPC,” explains Christian Eder of congatec, the chairman of the COM-HPC committee. “Thanks to this feature, OEMs and users will be able to ensure highest levels of reliability, availability, maintainability, and safety (RAMS) for their worldwide deployments of distributed network infrastructure equipment and edge/fog computing servers as well as IIoT gateways and clients. For individual needs, these COM functions can be expanded via an optional board management controller on the carrier board. This provides OEMs with a modular framework of uniform remote management functions that can be flexibly scaled to specific requirements.”

 The COM-HPC PMI specification is a supplement to the COM-HPC open standard and serves as a guide on how to achieve interoperability between COM-HPC modules from different vendors and combinations of carrier boards. It adapts the Intelligent Platform Management Interface (IPMI) specifications to COM-HPC designs and also touches the implementation of Redfish features.

 IPMI is a collection of side-band/out-of-band management commands that are used for system interaction. IPMI firmware generally runs on a board management controller, a discrete integrated circuit that is accessed via a network connection and/or serial interface, and/or LPC/eSPI. Redfish, a standard managed by DMTF, provides a Representational State Transfer (RESTful) interface for the management of systems. Redfish is still under active development, and it continues to evolve as new use cases are discovered.

 The COM-HPC PMI document describes three different PMI maturity levels for modules and two for carrier boards. The modules’ PMI maturity levels range from unmanaged module (M.U) and basic managed modules (M.B) to fully managed modules (M.F); and carrier board levels range from unmanaged (C.U) to managed carrier boards (C.M). The goal of specifying these different levels is to allow interoperability between multiple modules and carrier board designs. The different module management capabilities are broken down by their adherence to a set of IPMI commands listed below.

 The modular COM-HPC Platform Management Interface specification is available for download on the PICMG website at https://www.picmg.org/openstandards/com-hpc/  

The open specification for high performance compute modules is approved by the PICMG Consortium

Wakefield, MA., 2021 – PICMG, a leading consortium for the development of open embedded computing specifications, announces that COM-HPC has been approved and ratified, and is now available for public download and distribution.

“Twenty-six industry-leading companies worked together diligently and cohesively over a span of five years”, said Christian Eder, the COM-HPC Working Group Chair. “I owe a big thank you to the team for the dedication and excellence they all brought to the effort. It is a clear proof of the importance of the COM-HPC specification. Now we are well prepared to address current and future technology requirements.”

COM-HPC defines five module sizes to deliver edge server performance for small, rugged data centers. The specification addresses emerging requirements in the embedded and edge computing market. The base specification will be accompanied later this year by a Platform Management Interface Specification, COM-HPC EEEP, and a Carrier Board Design Guide.

“The PICMG organization is proud of the extraordinary collaboration between industry leaders that has led to the completion of the COM-HPC base specification, said Jess Isquith, president of PICMG. “The new open standard will enable multiple AI and Industry 4.0 applications, amongst others, to be realized by bringing server-level computing to the edge. Adopting the specification provides a necessary standard to reduce time to market and stabilize costs for hundreds of solutions providers.”

It is important to note that the specification covers two classes of modules.

The COM-HPC Client Module Type targets use in high end embedded client products that need one or more displays, a full set of low, medium, and extremely high bandwidth I/O, powerful CPUs and modest size. Typical uses are in medical equipment, high end instrumentation, industrial equipment, casino gaming equipment, ruggedized field PCs, transportation and defense systems and much more.
The COM-HPC Server Type targets use in high end headless (no display) embedded servers that require intensive CPU capability, large memory capacity, and lots of high bandwidth I/O including multiple 10Gbps or 25Gbps Ethernet, and up to 65 PCIe lanes, at up to PCIe Gen 5 speeds. Typical uses are in embedded server equipment ruggedized for use in field environments and applications such as autonomous vehicles, cell tower base stations, geophysical field equipment, medical equipment, defense systems and much more. Both client and server modules have a dedicated platform management interface which is the first for a COM standard to include remote administration.

This new specification does not replace COM Express, which will continue to play a crucial role in the COM marketplace for many years.

The specification documents are available for download on the PICMG website at picmg.org/open standards/com-hpc/. Also available is a preview document and additional resources to learn more about the specification.
