V480 Server's reliability, availability and serviceability features include:
Error correction and parity check for improved data integrity for memory and on internal data paths
Internal error detection and diagnosis capability, including via an internal 'back door bus'
Hot plug disks and hot swap power supplies.
Easily accessible LED status indicators.
Front panel LED display
Remote System Control (RSC) for monitoring and administrative capability
Automatic System Recovery (ASR) for isolation of failed components and automatic reboot capability
Environmental monitoring and fault protection
Watchdog timer
This hardware device is continually reset as long as the operating system is running. In the event of a system hang, the
timer will expire and force a reset/reboot. The timer must be enabled and the system rebooted in order to activate the
device.
MTBF
Detailed information concerning MTBF and availability may obtained using RAStool at:
http://ram-server.eng/
Alternatively, a detailed analysis report is available at:
http://ramserver.eng/RAM/Ram_ToolSer/PROJECTS/
DAKTARI/avail_analysis/
daktari_availability_report.html
These documents will indicate that the system can provide extremely high levels of availability. It is important to note the
method of analysis. For example, the system is fully operational without the RSC module which contains an industry
standard modem.
However, the characteristics of the modem do impact the overall system availability.
Therefore,
calculations are available with and without the RSC module included in the calculations.
MTTR
The vast majority of FRUs can be replaced in under 30 minutes by the average, trained service engineer.
Those
components requiring a longer time for replacement generally have a significantly higher MTBF.
The time for replacement does not include time for diagnosis.
