Fault Management Architecture
Overview
The Sun Fire X4540 server features the latest fault management technologies. With
the Solaris 10 Operating System (OS), the Sun Fire X4540 Server introduces a new
Fault Management Architecture (FMA) that diagnoses and predicts component
failures before they actually occur. This technology is incorporated into both the
hardware and software of the server.
At the heart of the Sun Fire X4540 server Fault Manager is the diagnosis engine. The
disk diagnosis engine receives data relating to hardware and software errors and
automatically and silently diagnoses the underlying problems. The diagnosis engine
runs in the background, silently capturing telemetry, until a diagnosis can be
completed or a fault can be predicted.
