Moving Management Module that moves the Need for BMCs on Every Server

Most servers have a Baseboard Management Controller (BMC) subsystem on the system motherboard to handle low-frequency tasks, such as measuring system health and reprogramming non-volatile memories out of band. This subsystem is typically about $30-worth of hardware (about $1,200 in a rack full of 1U servers), and is of limited value when the server is functioning properly and is executing the workload.

The novel design described herein positions the management subsystem on a vertical geared track with a solenoid activated push-pin connector to merge with the selected target server in the rack. The Moving Management Module (MMM) connects to the outside world via flexible looping power and Local Area Network (LAN) cables (similar to a print-head), and interface to the target system through I2C, analog input/output (I/O), General Purpose Input/Outputs (GPIOs), etc. at the target connector. The MMM can be programmed to visit each server either periodically or on demand. An additional option adds a horizontal component to the MMM's travel, such that a single ceiling or floor mounted MMM could move from rack to rack.

The MMM contains the same basic components as a standard BMC, plus the analog power circuits to control and/or drive the solenoid and track motor (these might be in the base, not on the moving component). The rack servers are specifically designed to function with the MMM, bringing out...
