and VT-d (Virtualized devices) VMM, as well as teardown of secrets in unexpected reset case. TXT support
provided in select Intel processors.
VT-d is a chipset technology that virtualizes directed I/O
Together, TXT and VT-d may be used to support verified launch of a known trusted
VMM that also may protect VMs from accessing each other's memory.
Computrace Computrace agent support standard
Tower Product can be oriented as a tower (in addition to desktop orientation)
Drive Lock Implementation of the industry standard ATA Security feature set. When enabled, it
prevents software access to user data on the drive until one or two user-defined
passwords are provided.
Drive Self Tests (DPS) * Drive Protection System
A diagnostic hard drive self test. It scans critical physical components and
every sector of the hard drive for physical faults and then reports any faults
to the user.
Running independently of the operating system, it can be accessed through
a Windows-based diagnostics utility or through the computer's setup
procedure. It produces an evaluation on whether the hard drive is the source
of the problem and needs to be replaced.
The system expands on the Self-Monitoring, Analysis, and Reporting
Technology (SMART), a continuously running systems diagnostic that alerts
the user to certain types of failures.
DPS Access through F10 Setup during
Boot
SMART Technology *
(Self-Monitoring, Analysis and Reporting
Technology)
Allows hard drives to monitor their own health and to raise flags if imminent failures
were predicted
Predicts failures before they occur. Tracks fault prediction and failure
indication parameters such as re-allocated sector count, spin retry count,
calibration retry count
By avoiding actual hard drive failures, SMART hard drives act as "insurance"
against unplanned user downtime and potential data loss from hard drive
failure
IOEDC: I/O Error Detection Circuitry
Detects errors in Read/Write buffers on HDD cache RAM
Interface in F10 setup for all dc7900 platforms provides confirmation of
SMART IV support.
SMART I – Drive Failure Prediction
SMART II – Off-Line Data Collection
SMART III – Off-Line Read Scanning
with Defect Reallocation
SMART IV – End-to-End CRC for hard
drives
* This feature is inoperable when a RAID (Redundant Array of Independent Disks) configuration is enabled.
