What Is Redfish?_
Redfish provides a modern, schema-based interface for monitoring, configuring, and managing hardware components such as power supplies, fans, and network interfaces. It replaces older protocols like IPMI with a more scalable and secure approach using HTTPS and JSON. In GPU data centers, Redfish is used to automate the bring-up and health checks of thousands of nodes.
Technical Details
Redfish operates over HTTPS and uses a RESTful model with resources organized in a tree structure, typically accessed via a baseboard management controller (BMC). It supports operations like power cycling, firmware updates, and sensor telemetry retrieval. The standard defines schemas for common hardware elements, but exact endpoints and capabilities vary by OEM implementation.
How Leviathan Systems Works with Redfish
During commissioning, Leviathan Systems uses Redfish to automate node discovery, verify firmware versions, and run initial health checks across the entire GPU cluster. It is a key tool for validating that each server is correctly configured before fabric bring-up.
