system management
Drive Protection System
The Drive Protection System (DPS) is a diagnostic tool built into the hard drives installed in
select HP workstations. DPS is designed to help diagnose problems that might result in
unwarranted hard drive replacement.
Each installed hard drive is tested using DPS, and a permanent record of key information is
written onto the drive. Each time DPS is run, test results are written to the hard drive. Your
service provider can use this information to help diagnose conditions that caused you to run
the DPS software. Refer to the Troubleshooting Guide for instructions on using DPS.
Ultra ATA Integrity Monitoring
Ultra ATA Integrity Monitoring monitors the integrity of data as it is transferred between an Ultra
ATA hard drive and the system’s core logic. If the workstation detects an abnormal number of
transmission errors, the workstation displays a Local Alert message with recommended actions.
ECC fault prediction and prefailure warranty
When the workstation encounters an excessive number of error checking and correcting (ECC)
memory errors, the workstation displays a Local Alert message. This message contains detailed
information about the errant memory module, allowing you to take action before you experience
non-correctable memory errors. The Prefailure Warranty for ECC memory modules allows you
to replace these modules, free of charge, before the modules actually fail. ECC memory modules
are optional on selected HP systems.
NOTE:
To use this feature, you must replace the standard DIMMs with HP ECC DIMMs.
surge-tolerant power supply
An integrated surge-tolerant power supply provides greater reliability when the workstation is hit
with an unpredictable power surge. This power supply is rated to withstand a power surge of up
to 2000V (Line to PE or Neutral to PE) and 1000V (Line to Line) without any data loss or system
downtime.
thermal sensor
The thermal sensor is a hardware and software feature that tracks the internal temperature of the
workstation. The thermal sensor monitors the processor temperature and if the temperature gets
too hot, the processor clock automatically begins to throttle. If the temperature does not go down,
then the system eventually shuts down.
