Technical Specifications
DASH 1.0 support (Desktop and
mobile Architecture for System
Hardware)
ASF 2.0 support (Alert Standard
Format)
TXT (Trusted Execution
Technology) and VT-d (Virtualized
devices)
Virtual Appliance support
Computrace
Tower
Drive Lock*
Drive Self Tests (DPS)*
DPS Access through F10 Setup
during Boot
SMART Technology*
(Self-Monitoring, Analysis and
Reporting Technology)
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.
Network Heuristics – built-in basic capabilities to filter inbound and outbound network
traffic. Backwards compatible with earlier management consoles
A standards initiative for representing out-of-band management capability for computer
systems. It is a secure, web-services based successor to ASF.
Industry-standard specification for network alerting in operating system-absent
environments
TXT allows for secure management (via TPM) and measured launch of 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.
Tested support for Virtual Appliance (VA) 2.6 ISV applications.
Hardware ready for future VA 3.0 ISV applications (with VT-d and TXT support)
Computrace agent support standard
Product can be oriented as a tower (in addition to desktop orientation)
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 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.
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 dc7800 CMT and SFF platforms provides confirmation
of SMART IV support.
