Abstract
A system for monitoring server blades includes a cabinet having a plurality of racks configured to receive a server blade. The server blade includes one or more microprocessors, memory, and a service processor all interconnected via one or more busses. The system includes a management blade to monitor the local service processors. Upon installation, a new blade identifies itself to the management blade by its physical slot position within the cabinet. In response to a reset, the local blade service processor determines from a tamper latch whether the blade has been removed from the chassis since the last power-on event. If the tamper latch is broken, the local service processor informs the management blade and resets the tamper latch. The local service processor of each blade may send a periodic heartbeat to the management blade, which monitors for loss of the heartbeat signal to determine when a blade is removed.
