1OU OCP Power Management Controller (PMC)
PMC SOFTWARE
The PMC software runs on Yocto Linux combining open source packages with customized driver and application software.
PMC Boot and Software / Firmware Update
Update via RedFish
The PMC software must allow update of all images in the system via the RedFish Update Service. These images include, but not limited to:
• uBoot images and other code in SPI flash
• Kernel and filesystem in eMMC
• PSU firmware images
It must be possible to download the new image while maintaining full functionality of the shelf. It is permissible to reboot into the newly downloaded
image - i.e. no 'live' update required.
Update via Command Line / Debug
It must be possible to update all the same images via command line over the SSH or debug UART connection.
Firmware Rollback
After updating the PMC firmware, it must be possible to rollback to the previous version easily, without downloading more images. This should be
done automatically if the new images fail to boot. It must also be possible to trigger this rollback manually. Ideally via Redfish but certainly via the
command line.
PMC Connected Shelf Monitoring
Redundancy Status
The PMC can be configured to have an expected number of active supplies. It will signal an alert via RedFish if the available number drops below that
is configured.
Communication Fault
The PMC will indicate through the attention LED if there is a communication error between the PMC and PSUs.
PMC System Communications
RedFish
The system provides a full Redfish interface aligned with the Redfish 2021.4 version. Where functionality is not available in Redfish OEM extensions
may be used. OEM extensions appear under the OEM name Advanced Energy.
Redfish is available over HTTP or HTTPS but HTTP can be disabled in the configuration. HTTPS certificates are self-signed.
SSH Command Line and Tools
The system provides a Linux command line with a standard set of configurations, diagnostic and debug tools. These are aligned with other hyperscale
products.
Other PMC Functionality
Network Configuration
The PMC Ethernet configuration can be configured into DHCP or Static address mode either via Redfish, the command line or the web interface. All
normal network settings should be configurable.
Logging
The PMC should store logs from its various processes at different logging levels following the Linux standard. The default logging level should be
ERROR and this can be read and configured via Redfish or the command line.
The logs should be available via Redfish or the command line.
