Server Features 11
Environmental Monitoring
The SPARC Enterprise T5140 and T5240 servers feature an environmental
monitoring subsystem that protects the server and its components against:
■ Extreme temperatures
■ Lack of adequate airflow through the system
■ Power supply failures
■ Hardware faults
Temperature sensors are located throughout the system to monitor the ambient
temperature of the system and internal components. The software and hardware
ensure that the temperatures within the enclosure do not exceed predetermined safe
operating ranges. If the temperature observed by a sensor falls below a low-
temperature threshold or rises above a high-temperature threshold, the monitoring
subsystem software lights the amber Service Required LEDs on the front and rear
panels. If the temperature condition persists and reaches a critical threshold, the
system initiates a graceful system shutdown. In the event of a failure of the system
controller, backup sensors protect the system from serious damage, by initiating a
forced hardware shutdown. Service Required LEDs remain lit after an automatic
system shutdown to aid in problem diagnosis.
The power subsystem is monitored in a similar fashion by monitoring power
supplies and reporting any fault in the front and rear panel LEDs.
Support for RAID Storage Configurations
You can set up hardware RAID 1 (mirroring) and hardware RAID 0 (striping)
configurations for any pair of internal hard drives, providing a high-performance
solution for hard drive mirroring.
By attaching one or more external storage devices to the SPARC Enterprise T5140
and T5240 servers, you can use a RAID software application such as Solstice
DiskSuite™ or VERITAS Volume Manager
1
to configure system drive storage in a
variety of different RAID levels.
1. Software RAID applications such as VERITAS Volume Manager are not included with this server. You must
obtain and license them separately.
