4. RAS
RAS stands for Reliability, Availability and Serviceability and is a specific OMRON designed
solution for the DyaloX to make it a true Industrial PC. Inside the DyaloX Industrial PC series,
a separate board, interfaced by embedded RAS utility software, continually monitors the
motherboard. Because this unique RAS board is a stand-alone board, it can gather data from
the motherboard no matter what the Operating System or hardware conditions of the DyaloX
are. The RAS solution can notify you when unstable hardware or software conditions are
detected. It can if needed take action to automatically resolve the failure and enables you to
investigate the causes of the failure.
Warning threshold levels can be set manually in the RAS utility. Data logged at time of failure,
such as motherboard temperatures, voltages, date and time, and other relevant data can be
uploaded from the RAS board for analysis.
So whatever the reason for failure, the RAS board is able to provide a system snapshot just
before failure occurs. By analyzing the log data, the trend and cause of failures can be quickly
found and rectified for higher reliability in the future.
The DyaloX Industrial PC series with its RAS functionality will help you achieve the highest
possible reliability in your PC Based application(s).
4.1 RAS Functions
The RAS system in OMRON Industrial PC provides the following main functions:
•
Monitoring Function that constantly monitors the hardware and software of an
industrial PC and gives the user failure notification when an error is detected or a
failure occurs.
•
Auto-recovery Function that forcefully shuts down the system when a failure occurs
to prevent further faults and reboot the system for recovery.
•
Logging Function that saves events in operating an industrial PC (such as Power
Supply ON/OFF, OS startup/shutdown, etc.), system status when a failure occurs and
conditions of the Motherboard (temperature, power supply) onto the RAS Board's
power-backed-up memory.
•
Log Analysis Function that analyzes cause and/or tendency of failures using
numerous amounts of logs saved on the memory.
