HP Compaq dc7800 Business PC

Technical Specifications

	Network Heuristics – built-in basic capabilities to filter inbound and outbound network
	traffic. Backwards compatible with earlier management consoles
DASH 1.0 support (Desktop and	A standards initiative for representing out-of-band management capability for computer
mobile Architecture for System	systems. It is a secure, web-services based successor to ASF.
Hardware)
ASF 2.0 support (Alert Standard	Industry-standard specification for network alerting in operating system-absent
Format)	environments
TXT (Trusted Execution	TXT allows for secure management (via TPM) and measured launch of VMM, as
Technology) and VT-d (Virtualized	well as teardown of secrets in unexpected reset case. TXT support provided in
devices)	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.
Virtual Appliance support	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	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
DPS Access through F10 Setup
	produces an evaluation on whether the hard drive is the source of the problem
during Boot
	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.
SMART Technology*	Allows hard drives to monitor their own health and to raise flags if imminent failures
(Self-Monitoring, Analysis and	were predicted
Reporting Technology)	Predicts failures before they occur. Tracks fault prediction and failure indication
SMART I – Drive Failure Prediction
	parameters such as re-allocated sector count, spin retry count, calibration retry
SMART II – Off-Line Data Collection	count
	By avoiding actual hard drive failures, SMART hard drives act as "insurance"
SMART III – Off-Line Read
	against unplanned user downtime and potential data loss from hard drive failure
Scanning with Defect Reallocation	IOEDC: I/O Error Detection Circuitry
	Detects errors in Read/Write buffers on HDD cache RAM
SMART IV – End-to-End CRC for
	Interface in F10 setup for dc7800 CMT and SFF platforms provides confirmation
hard drives
	of SMART IV support.

* This feature is inoperable when a RAID (Redundant Array of Independent Disks) configuration is enabled.
