OpenBMC: One board management software for all hardware at Facebook

What this post added

This post details the extension of OpenBMC to support Facebook's NVMe-based storage platform, Lightning. It describes the unique interface requirements for managing Lightning's BMC (USB, I2C, PCIe) due to the absence of a traditional NIC, and introduces new features like 'fscd' for fan control, 'log-util' for capturing secondary device logs, and 'flash-util' for reading SSD sideband status and managing the PCIe switch. The post highlights how this brings uniform board management across all Facebook data center hardware, simplifying provisioning and improving fault analysis.
